Property developer One Living, backed by former Macquarie banker turned investment manager Chris Green’s investment firm, has unveiled plans to bring more institutional capital into housing to help address the national supply crisis.

The New York-based investor has focused his firm, GreenPoint Partners, on addressing the supply shortage hitting middle market housing in Australia.

It is backing the new One Living business to develop more than 1000 units along the eastern seaboard. The new firm is starting with a development on Mona Vale Road, on the border of Mona Vale and Pymble, in Sydney’s Northern Beaches, with around 140 apartments planned. They are eyeing off more sites across the city.

With cost pressures rising in the industry, One Living’s model is to be a vertically integrated developer-builder, so it can respond directly to the housing gap by removing the cost inefficiencies embedded in traditional residential delivery.

“We are building a platform designed to operate at scale and starting in a market where there’s a clear need for quality, attainable housing,” One Living joint managing director Joseph Scuderi said.

“It’s that missing middle – it’s that attainable end of housing… that’s what most Australians invest into and what Australians can actually afford.”

GreenPoint Partners brings years of experience assembling and scaling real estate operating businesses across major markets. And Green sees a big opportunity in Australia.

“For its size, sophistication and importance to the community, Australia’s living sector has remained largely under-institutionalised, which represents significant opportunity,” Green said. “GreenPoint identified that gap, assembled the right team, and is backing One Living to build a platform that is aligned to market needs.”

Green said being a builder-developer would give the company the capacity and flexibility it required to deliver reasonably-priced homes.

“We want it to be at that attainable level; not super high end luxury but at that attainable level,” he said.

&nbsp;

One Living will undertake a component of affordable housing in its schemes, which it will own and operate, and it could also run build-to-rent on some sites.

Green praised local policy settings.

“The NSW government is being very supportive, strategic and pragmatic in terms of how do we generate more supply of housing,” he said. “We think it’s actually positive for development and the bit that’s been lacking at that attainable level is that it’s lots of relatively small private developers, whereas we want to create an institutional platform.”

One Living is also&nbsp;looking at high-density projects and could take on more institutional funding in the future.

“The way we will be able to achieve economies of scale is through size,” Green added.

One Living enters Sydney's new apartment market with Northern Beaches site acquisition

It's been several years since there's been an opportunity to buy a brand new townhome in Melbourne's coastal suburb of Mordialloc. Even apartment developments in recent times have been few and far between in the area.

Local developer LDS Property identified the gap in new housing, securing a site on White Street, directly opposite&nbsp;Woodlands Golf Club Mordialloc. They've recently launched&nbsp;<a href="https://www.apartments.com.au/new-townhouses/wm-residences-mordialloc-102-white-street-mordialloc-vic-3195">WM Residences</a>, just 13 townhouses which they have already started building.

Projects by Buxton Director Heath Thompson, who is selling WM Residences, says the townhouses x that perfect middle ground be

"Mordialloc residents have had limited options to downsize within the suburb, often forcing them to look elsewhere despite long-standing ties to the area," Thompson says.

"With very little comparable new supply coming to market, projects like WM Residences are well placed, particularly as buyers look to capitalise on current conditions amid constrained supply."

[smartcode_project:default project_id=134646 project_image_fid=6109]

The development, designed by regarded architecture firm&nbsp;<a href="https://www.apartments.com.au/architects/ewert-leaf">Ewert Leaf</a>,&nbsp;adopts a deliberately restrained architectural approach, focusing on simplicity, durability and liveability rather than overt design gestures.

The boutique scale is central to the offering. With only 13 three-bedroom residences, each home is configured to prioritise functional layouts and everyday use, supported by private terraces and secure two-car garages.

Ewert Leaf’s design response leans into a calm, neutral material palette. Interiors are defined by oak flooring, white walls and soft finishes, creating a consistent and understated backdrop. The approach avoids trend-driven detailing in favour of longevity, with an emphasis on natural light and spatial clarity.

[smartcode_project:default project_id=134646 project_image_fid=6110]

Beyond aesthetics, the homes are designed to meet contemporary performance expectations. Each residence targets a minimum 6-star energy rating, incorporating double glazing, comprehensive insulation and all-electric Bosch appliances.

The project’s location supports a walkable coastal lifestyle, sitting within close proximity to Mordialloc’s foreshore, Main Street retail strip and the train station. Local cafés and dining venues, including Suburbia Deli and Hendriks Café, are within a short walk, reinforcing the area’s established neighbourhood character.

[smartcode_project:default project_id=134646 project_image_fid=6116]

While <a href="https://www.apartments.com.au/developments/mordialloc-vic-3195">Mordialloc</a> is often defined by its beach and pier, the project taps into other areas of day to day living, offering easy access to local food, casual dining and transport, rather than positioning itself purely as a lifestyle retreat.

WM Residences reflects a continued trend across Melbourne’s coastal suburbs towards smaller-scale, design-led townhouse developments, particularly on infill sites where proximity to amenity is already established.

With construction commenced prior to its market entry, the project aligns with a growing preference among buyers for developments with visible progress and defined delivery timeframes.

WM Residences fills gap in Mordialloc townhouse market

Developer GURNER™ Group has revealed $1.65 billion in residential sales nationally across the 12 months to December 2025, driven largely by the continued momentum of its Docklands wellness-focused precinct, Elysium Fields.

The sales result was generated across seven projects in Victoria and New South Wales, headlined by Elysium Fields, GURNER™’s $2.75 billion mixed-use precinct planned for Harbour Esplanade in Docklands.

The project has recorded more than $500 million in sales across the first three towers, equating to around 580 apartments sold.

The first tower, Helios, has now sold out of its 240 private residences, with GURNER™ preparing to release a premium penthouse collection comprising 15 three-bedroom penthouses in coming weeks.

[smartcode_project:default project_id=144441 project_image_fid=370975]

Elysium Fields is being developed on the long-held 20,000 sqm Docklands site at 208-226 Harbour Esplanade, which had remained undeveloped for more than two decades prior to GURNER™ taking over the project around four years ago.

Construction has now commenced across four towers ranging between 18 and 30 storeys, with Hamilton Marino and Maxcon appointed as builders.

Once complete, the precinct is expected to comprise around 1,100 residences, alongside retail, hospitality and public realm uses integrated throughout the site.

[smartcode_project:default project_id=144441 project_image_fid=370981]

Designed by Fraser &amp; Partners in collaboration with GURNER™ Design House, the project has been positioned around the developer’s broader focus on wellness-led residential living.

“We don’t sell apartments. We create a true luxury lifestyle that simply doesn’t exist elsewhere in the market today,” Founder and Executive Chairman Tim Gurner said.

“To deliver that requires an extraordinary level of detail, coordination and discipline across multiple verticals, from design and hospitality through to wellness and service.”

“We’ve always believed that living extends far beyond the physical residence. It’s about how you feel the moment you arrive, how you live day-to-day, and the ecosystem that supports that.” 
[smartcode_project:default project_id=144441 project_image_fid=370977]

The project’s design places a heavy focus on landscaping, wellness amenities and biophilic design principles.

Plans include around 3,700 sqm of landscaped gardens and open space throughout the precinct, alongside a retail and dining offering spanning approximately 5,000 sqm.

The broader public realm strategy centres around what GURNER™ describes as the “Path of Life”, an urban forest and landscaped pedestrian environment intended to connect the various buildings and wellness spaces across the precinct.

The apartments themselves will incorporate a range of wellness-focused inclusions, including purified air and water systems, circadian lighting, antimicrobial surfaces, and optional in-home wellness upgrades.

[smartcode_project:default project_id=144441 project_image_fid=370980]

Gurner said the company’s experience through its Saint Haven wellness clubs had directly informed the residential offering now being incorporated into Elysium Fields.

“We’re seeing a clear global shift toward longevity, performance and proactive health,” Gurner said.

“Our role is to deliver that in a way that feels seamless, highly private and beautifully resolved within the environments we create.”

A large component of the wellness offering is planned through the resident amenity and health facilities proposed within the precinct.

That includes plans for bathing and recovery facilities spread throughout the towers, incorporating mineral pools, saunas, steam rooms, flotation therapy, red light therapy and wellness lounges.

The developer is also seeking approvals for what it describes as a “reverse ageing medical clinic” within the precinct.

[smartcode_project:default project_id=144441 project_image_fid=370978]

According to project information released by the group, the proposed facility would include cryotherapy, IV infusion therapy, infrared and dry saunas, PEMF beds, MRIs, DEXA scans, brain scans and blood analysis services.

Within the first tower, Helios, residents will also have access to a dedicated amenity offering known as the Sky Private Club.

The upper 15 levels of the building will include private lounges, dining spaces, rooftop amenities and optional private wellness studios integrated within residences.

The Helios tower itself comprises 260 apartments ranging between 60 sqm and 300 sqm, including a collection of penthouses.

That includes a planned two-storey penthouse spanning around 600 sqm with uninterrupted bay views.

The Elysium Fields precinct is being delivered in partnership with Digital Harbour Holdings, a consortium that includes the Liberman family, which controls the development rights across the Docklands site.

[smartcode_project:default project_id=144441 project_image_fid=370979]

The sales result comes as GURNER™ continues expanding its national development pipeline beyond Victoria.

“We have a strong pipeline across Australia and are now focused on scaling into key markets including New South Wales and Queensland, while continuing to build on our Melbourne base,” Gurner said.

“We currently have more than $3 billion in the market, growing to over $5 billion by October, and expect to materially outperform last year in the 2026 calendar year.”

The result also reflects the continued strength of the upper-end apartment market in Melbourne, particularly for owner-occupier-focused product with large-scale amenity and lifestyle offerings.

Record result anchored by the Group’s “utopian” Elysium Fields precinct – defying market headwinds in Docklands.

Elysium Fields drive Gurner to $1.65 billion in apartment sales over 2025

National Australia Bank (NAB) will fund <a href="https://www.apartments.com.au/new-apartments/palmera-residences-gold-coast-18-garfield-terrace-surfers-paradise-qld-4217">Palmera</a>, a $1 billion, 52-level luxury residential tower being developed by Central Equity in one of the Gold Coast’s most tightly held coastal locations at Northcliffe.

The project, launched recently by <a href="https://www.apartments.com.au/developers/central-equity">Central Equity</a>, one of Victoria’s largest private residential developers, comes at a time when construction funding for large residential developments has become increasingly competitive as lenders tighten exposure to the sector.

Multiplex has been appointed the builder, and construction is now underway.

[smartcode_project:default project_id=108274 project_image_fid=365784]

Since its first project, Central Equity has delivered more than 85 residential developments with a combined end value exceeding $8 billion.

Palmera reflects Central Equity’s growing focus on the Gold Coast luxury apartment market and continues a relationship between Central Equity and NAB that dates back to the late 1980s, when the bank funded one of Melbourne’s earliest inner-city residential towers at a time when high-rise apartment living in the CBD was largely unproven.

“NAB’s funding of Central Equity’s $36 million CBD development in the late 1980’s to the financing of the billion-dollar tower today highlights the long-term relationship between the two organisations in delivering major residential projects” said Central Equity Founder and Chairman Eddie Kutner.

He said NAB’s early support was instrumental in helping establish the company’s development model.

“When we commenced our first residential tower in the late 1980s the concept of funding off-the-plan apartments was still largely untested in Australia,” Kutner said.

“NAB recognised the opportunity early and supported the project when others were uncertain. That relationship has now continued for more than 37 years across many developments.”

[smartcode_project:default project_id=108274 project_image_fid=365771]

Central Equity was established in 1987 when Melbourne’s CBD and Southbank precinct were still dominated by warehouses and commercial buildings. Fewer than 100 residents lived in Southbank at the time, and large-scale residential development in the inner city was not widely considered.

Recognising changing demographics and lifestyle preferences, the company began developing high-rise residential projects designed to bring permanent residents into the city centre.

Central Equity has provided accommodation for approximately 40,000 residents across Melbourne’s CBD and Southbank, while also incorporating supporting infrastructure including essential lifestyle facilities like retail spaces, childcare facilities and neighbourhood activity centres.

Central Equity has spent many years assembling the Palmera development site on the corner of Garfield Terrace and Frederick Street in Northcliffe, creating a supersite of around 3,300 sqm.

The developer said the Palmera apartment tower reflects its long-term view of the Gold Coast as a growing and increasingly diversified economy.

[smartcode_project:default project_id=108274 project_image_fid=365768]

Supported by infrastructure including the light rail network, major road upgrades expanded education, hospital and medical facilities and continued expansion at the Gold Coast Airport with more international and domestic flights.

Positioned in the tightly held Northcliffe precinct, the 52-level tower will deliver 347 apartments, targeting buyers seeking a high-end coastal lifestyle, from downsizers to interstate investors.

Designed by Marchese Partners with interiors by DBI, Palmera has been conceived as a next-generation residential offering, featuring a collection of oversized apartments, with premium three-bedroom residences offering sweeping northern views stretching from Surfers Paradise through to Burleigh Heads.

NAB funds $1 billion Surfers Paradise apartment development, Palmera

Two years after completing one of the newest developments in North Sydney, developer <a href="https://www.apartments.com.au/developers/aqualand-australia">Aqualand</a> is turning its attention to the rapidly evolving St Leonards apartment market.

The developer, which completed AURA by Aqualand on North Sydney's Walker Street, has lodged plans for a 5,918 sqm site at <a href="https://www.apartments.com.au/new-apartments/33-37-herbert-street-st-leonards-nsw-2065">33-37 Herbert Street, St Leonards,</a> seeking approval for a pair of residential towers rising above a shared podium opposite Royal North Shore Hospital.

The proposal forms part of the broader transformation underway across the St Leonards-Crows Nest precinct, where former industrial and commercial sites are increasingly being redeveloped into high-density mixed-use projects tied to major transport infrastructure.

<img alt="Aqualand" data-entity-type="file" data-entity-uuid="2cc428cf-fe70-4cac-9cd5-264ad53af62c" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-05-28%20at%209.51.56%E2%80%AFAM.png?VersionId=otKSnHtbjAvAddOnovyXQMgcAwE6DMe1" />

According to the planning documents, the site sits “within the St Leonards–Crows Nest Strategic Centre, identified by the NSW Government as a key area for accommodating future jobs and housing across Sydney.”

The proposal has been designed by fjcstudio, formerly FJMT Studio, and is being progressed through the State Significant Development pathway due to its scale and affordable housing provision.

The scheme would comprise 413 apartments, including 46 affordable housing units, alongside retail and commercial uses fronting Herbert Street. The project would also include communal open space, landscaping, a swimming pool, gymnasium, children’s play areas and podium-level resident amenities.

Planning documents show the development would consist of a part-13, part-39 storey tower form positioned above a four-storey podium.

“The development comprises a unified podium that activates the street interface, and two setback towers to accommodate new housing supply while maintaining an appropriate human scale at ground level,” fjcstudio noted in its Design Report.

The northern and southern towers have been shaped to respond to the surrounding skyline while also limiting overshadowing impacts to nearby public open space, particularly Talus Reserve.

The design report said the differing tower heights were intended to “contribute to a varied skyline while responding to the surrounding built form context and solar access considerations.”

<img alt="Aqualand" data-entity-type="file" data-entity-uuid="36da62dc-ff9e-41f2-a7e3-7be38373751c" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-05-28%20at%209.51.45%E2%80%AFAM_0.png?VersionId=Mo6Rp2r.XRLTzIfg_PEEpw8NepDH8UBs" />

The site sits directly opposite Royal North Shore Hospital and within walking distance of both St Leonards Station and the new Crows Nest Metro station.

While the site itself sits just outside the formal Crows Nest Transport Oriented Development boundary, the planning documents repeatedly reference its alignment with the broader TOD objectives reshaping the Lower North Shore.

“The site is located adjacent to St Leonards Station and in close proximity to Crows Nest Metro which is within the Crows Nest Transit Orientated Development Accelerated Precinct which has been identified by the NSW Government to support housing delivery,” the Design Verification Statement noted.

According to fjcstudio, the project has been designed to respond to the broader transition occurring across St Leonards, where increasing residential density is being concentrated around transport infrastructure and employment hubs.

“The broader precinct is undergoing significant change, with a mix of existing mid-rise buildings and newer high-density developments,” the report stated.

“Recent and approved projects indicate a consistent shift toward taller built form, typically organised as tower-and-podium typologies with more active ground levels.”

The proposal includes close to 6,000 sqm of retail and commercial space across the ground floor and podium levels, designed to create a more activated street edge along Herbert Street.

Aqualand’s plans would also introduce a landscaped podium shared between the two towers, with communal open space in the form of a podium rooftop designed to support resident interaction and improve urban greening outcomes. The scheme would also introduce pocket parks at the northern and southern ends of the site, including a landscaped area at the corner of Herbert and Ella streets designed to improve pedestrian amenity and soften the streetscape.

&nbsp;

The proposal is being progressed through the NSW Government’s Housing Delivery Authority pathway, which was introduced to accelerate housing supply across the state. The application was declared State Significant Development in April 2025 following an expression of interest process.

<img alt="Aqualand" data-entity-type="file" data-entity-uuid="faf6d97d-2671-454f-b85a-fe1c6a7be608" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-05-28%20at%209.51.49%E2%80%AFAM.png?VersionId=diVd28OBVr5.YV.7prrOz.uAanwwwm7a" />

St Leonards has been particularly active with new developments in recent weeks. Developer SP Setia’s <a href="https://www.apartments.com.au/news/nsw/first-look-sp-setia-targets-st-leonards-skyline-with-40-storey-tod-tower">plans for a new 42-storey tower</a> recently went on exhibition through the same pathway, while <a href="https://www.apartments.com.au/news/nsw/first-look-stockland-plans-52-storey-538-apartment-st-leonards-tower">Stockland’s 52-storey tower proposal</a> was also recently unveiled.

Aside from the St Leonards project, which is expected to take around nine months to move through the approvals process ahead of a potential 2027 launch, Aqualand is also preparing to launch Boronia, a new apartment project in Roseville comprising around 111 apartments on Larkin Street.

The developer also has approvals in place for the next stage of the Barangaroo precinct, which will feature new residential, retail, hospitality and community uses, alongside a new metro entry across the five-hectare site.

More than 50 new retail destinations are planned for Central Barangaroo, alongside a 270-metre-long boulevard connecting Hickson Park to Nawi Cove. Together with Harbour Park, more than 50 per cent of the precinct will comprise public open space and parkland.

Global Warming

<html><body>
GUEST INSIGHTS

In cities around the world, temperatures could rise by <a href="https://www.scientificamerican.com/article/cities-face-withering-heat-under-worst-warming-scenarios/">more than 4℃</a> by 2100 under a high-emissions climate change scenario, suggests <a href="https://www.nature.com/articles/s41558-020-00958-8">research published this week</a> in Nature Climate Change.

It comes as the Bureau of Meteorology’s <a href="http://www.bom.gov.au/climate/current/annual/aus/">annual climate statement</a>, released today, shows 2020 was Australia’s fourth-warmest year on record, despite being an “La Niña” year, which usually leads to cooler temperatures.

Cities occupy just 3% of Earth’s surface. As this portion of land is so small, they’ve typically been left out of most climate models, which generally make projections on global scales.

Yet more than half the world’s population live in urban environments (set to jump to 70% by 2050). This is why the researchers call for “multi-model projections” of local climates for cities.

In the study, the researchers say their predictions on climate will give “urban planners and decision-makers in any city […] access to city-specific projections for any planning horizon they need”.

It’s important these planning horizons include the cooling and shading provided by <a href="https://theconversation.com/heres-how-green-infrastructure-can-easily-be-added-to-the-urban-planning-toolkit-57277">green infrastructure</a> — the network of green spaces such as street trees and green walls — in urban areas.

For Australia, this means getting a national green infrastructure policy that provides for green spaces within our cities, open spaces and buildings to help with increasing density and rising global temperatures.

What the research found

Heat events, such as heatwaves, pose <a href="https://www.health.gov.au/health-topics/emergency-health-management/heatwave-health-tips-and-information">a significant health risk</a> and can <a href="https://theconversation.com/smart-urban-design-could-save-lives-in-future-heatwaves-33246">hit people harder in cities</a>.

Cities are hotter than in surrounding regional areas due to “<a href="https://www.nationalgeographic.org/encyclopedia/urban-heat-island/">the urban heat island</a>” effect, a result of heat created by all the densely packed people, vehicles and industries, and the heat retained among buildings and other infrastructure.

Despite having the highest population density, the researchers point out that urban areas aren’t often represented in the <a href="https://www.wcrp-climate.org/wgcm-cmip/wgcm-cmip5">Coupled Model Intercomparison Project</a>. This project is important because it informs the global authority on climate change (the <a href="https://www.ipcc.ch/report/ar5/syr/">International Panel on Climate Change</a>).

So the research authors built a statistical model emulating a complex climate model with urban regions. And they estimate that, by the end of the century, average warming across global cities will increase by 1.9℃ under an intermediate emissions scenario, and 4.4℃ with high emissions.

Urban warming would most affect mid-to-northern parts of the United States, southern Canada, Europe, the Middle East, northern Central Asia and northwestern China.

They also predict that the <a href="https://www.weather.gov/ama/heatindex#">heat index</a> would increase faster than air temperature alone over almost all cities. “Heat index” refers to how hot the human body actually feels, a combination of relative humidity and air temperature. This would mean urban residents would experience higher heat stress.

What does this mean for Australia?

While the research found most urban warming would occur in the northern hemisphere, Australian cities are also projected to continue to warm. But we need only look to the recent record-breaking years to realise climate change will result in more extremely hot days here.

2019 was <a href="http://www.bom.gov.au/state-of-the-climate/future-climate.shtml">Australia’s hottest</a> (and driest) year on record. And today’s <a href="http://www.bom.gov.au/climate/current/annual/aus/">annual climate statement</a> from the Bureau of Meteorology shows the highest temperature ever recorded in the Sydney Basin, at a whopping 48.9℃, occurred in 2020, on January 4. It also found the average national temperature for 2020 was 1.15℃ higher than normal.

These are nationwide findings, but how Australia manages climate in urban areas is particularly important as around <a href="https://www.abs.gov.au/statistics/people/population/regional-population/latest-release#capital-cities">80% of population growth</a> occurs in capital cities.

In fact, <a href="https://www.sciencedirect.com/science/article/abs/pii/S0169204620301407">2020 research</a> found we’re increasingly facing more frequent and prolonged heatwaves that intensify urban heat islands in places such as Sydney, by raising inland temperatures by as much as 10℃ more than in coastal zones.

Keeping cities cool

The best way to ensure our cities are kept cool is through greening urban spaces. Green spaces can be developed by planting trees in streets, yards and parks for shade, recreation and relief from the heat. This will create cooler urban “microclimates” for social interaction and <a href="https://theconversation.com/cities-will-endure-but-urban-design-must-adapt-to-coronavirus-risks-and-fears-135949">natural retreats</a> from city life.

<a href="https://www.dpie.nsw.gov.au/premiers-priorities/greening-our-city">Greater Sydney</a>, for example, has a welcome new policy to ensure five million more trees are planted by 2030. This is an important long-term goal as <a href="https://www.sciencedirect.com/science/article/abs/pii/S221067071630066X">2016 research from Canada</a> found tree cover in daytime reduced air temperature by up to 4℃ in Montreal city.

The design of buildings and their immediate surroundings are also important to help manage increasing heat in our cities.

Our open spaces are places of exercise, retreat, relaxation and, in a new COVID world, socially distant interactions. The pandemic has allowed us <a href="https://www.smh.com.au/national/nsw/popularity-of-parks-prompts-call-for-ideas-to-re-imagine-public-spaces-20200715-p55c5z">to rediscover</a> the importance of our community and local connections in these spaces.

Multi-storey buildings also provide opportunity for vertical greening. The Victorian government, for example, is seeking <a href="https://www.planning.vic.gov.au/policy-and-strategy/planning-for-melbourne/plan-melbourne/cooling-greening-melbourne/green-wall-on-the-go">to increase</a> the amount of green infrastructure in our urban areas to help us cope with predicted warmer conditions.

Australia needs a national planning policy

Urban planning and greening urban spaces is largely a local government responsibility, usually overseen by state and territory governments.

And there is national recognition of the importance of green cities through the federal government’s <a href="https://www.infrastructure.gov.au/cities/smart-cities/plan/index.aspx">Smart Cities Plan</a>. It states:

Green, sustainable cities […] improve the quality of air and water, reduce the heat island effect, protect biological diversity and threatened species, and enhance general amenity.

But what’s needed, urgently, is a national planning framework of green city principles so no regions get left behind. Climate change is a national issue, and all urban residents from all socioeconomic backgrounds should benefit from green cities.

This national planning policy would describe how our cities across the nation should develop appropriately spaced trees and other vegetation, to better manage and prepare for increasing density and greater activity as climate change brings hotter weather.

And importantly, more research is needed to better inform climate models. We need more information into the ways our climates will change within different land areas — whether rural, suburban or in cities — so we can develop better national plans for how we will live and work in the future.

Cities could get more than 4°C hotter by 2100, Australia needs a national planning policy

<html><body>
The Carbon Risk Real Estate Monitor (CRREM) has announced the public release of decarbonisation pathways for the global real estate sector, and the finalisation of the tool to identify and manage transition risks for individual assets.
The pathways will reportedly help market participants meet the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD).
The downscaling pathways published today on the CRREM website identify annual energy- and carbon-intensity trajectories until 2050 across real estate markets and sectors that are consistent with keeping global warming below 2 degrees Celsius.
This is a policy goal endorsed by most municipal and national governments and thereby constitutes a plausible scenario against which future climate-related transition risk can be assessed.
The major investors supporting CRREM aim to establish it as a global standard for developing long-term decarbonisation pathways in the real estate sector based on a transparent and scientifically rigorous methodology.
CRREM covers 28 countries in Europe, North America and Asia-Pacific across the commercial real estate sector, including retail, offices, and logistics, as well as the residential sector.
According to the organisation, real estate plays a major role in combatting climate change.
The construction and operation of buildings accounts for 39 percent of energy-related greenhouse gas emissions globally, and much higher percentages in densely populated urban centres.
This exposes the real estate sector to significant climate-related transition risk as governments have started to impose increasingly stringent regulations on energy use and emissions from buildings to meet their own climate goals.
Regulatory risk around energy and carbon is shaping market and technology trends in the real estate sector.
As temperature is projected to rise 3.8 degrees Celsius under current legislation, the decarbonisation pathways aligned with 1.5- and 2-degree global carbon budgets reflect significant reduction requirements beyond current legislative requirements.
CRREM estimates that the carbon-intensity of the building sector will globally have to decline from currently approx. 52 kgCO2e/m2/pa to below 10 kgCO2e/m2/pa by 2050 in order to be in line with the 2-degree global carbon budget.
Such a scenario would have significant implications for long-term asset planning and risk management in the sector – especially for developed countries which in some cases are facing 100 kgCO2e/m2/pa as a starting point for office buildings (based on a whole-building approach).
Calculation of the global reduction targets and the derived national targets for different asset classes in the real estate sector create added-value for investors.
Added value for example includes the transparent analysis of carbon risks, calculation of the abatement costs and analysing the correct timing of retrofit measures that are needed to minimize climate-related transition risk.
Along with the pathways, CRREM also finalized the development of a tool to manage stranding risk for individual buildings.
All information required is aligned with the information GRESB collects at the asset level in order to assess and benchmark the performance of real asset portfolios. The software is Excel-based and has undergone a significant testing phase. It is available on the crrem.eu website.
The decarbonisation pathways were developed by the Austria-based Institute for Real Estate Economics (IIÖ), with technical support from GRESB.
The initiative was funded by APG, PGGM and Norges Bank Investment Management (NBIM) and received further support from Japan’s Government Pension Investment Fund and Ivanhoé Cambridge.

Carbon Risk Real Estate Monitor announces decarbonisation plan

GUEST OBSERVATION
Last month, the Australian National University contracted with the Social Research Centre (SRC) to survey more than 3,000 Australian adults about their experiences and attitudes related to the bushfires.
The <a href="https://csrm.cass.anu.edu.au/research/surveys/anupoll" target="_blank">study</a> is the first of its kind to gauge how people were affected by the crisis and how it changed their views on a range of subjects, from climate change to the government response.
More than half of Australians felt anxiety
Our research shows the vast majority of Australians were touched in some way by the fires. We asked about eight different forms of impact, from lost property to disrupted holiday plans to difficulty breathing from the smoke.
About 14.4% of our respondents experienced direct exposure to the fires, either through their property damage or evacuations.
We can extrapolate further by looking at population <a href="http://stat.data.abs.gov.au/Index.aspx?DataSetCode=ERP_QUARTERLY" target="_blank">estimates</a> from the ABS and the number of visitors to areas impacted by the bushfires from the <a href="https://www.tra.gov.au/Domestic/domestic-tourism-results" target="_blank">National Visitors Survey</a> to estimate the total number of people directly affected at around 3 million.
And 77.8% of our respondents reported indirect exposure to the fires, such as having a friend or family member with damaged or threatened property, having travel or holiday plans disrupted, being exposed to the physical effects of smoke or feeling anxious or worried about the fires.
Breaking the data down by individual category, the severity of the <a href="https://www.propertyobserver.com.au/https://www.abc.net.au/news/health/2020-01-07/prolonged-bushfire-smoke-creates-new-health-risks/11844934">public health challenges</a> becomes more clear.
Nearly six in 10 respondents (57%) said they were physically affected by the smoke, while 53.6% said they felt anxious or worried about the fires.
Confidence in the government declined
The long-running <a href="https://australianelectionstudy.org/">Australian Election Study</a> has shown that confidence in the federal government has declined substantially in the past few decades.
Crises have the potential to restore some of this trust if dealt with effectively and transparently. However, the government’s handling of the recent bushfire crisis seems to have had the opposite effect.
Confidence in the federal government declined by 10.9 percentage points from 38.2% in our survey in October 2019 to 27.3% by January 2020.
Confidence in other institutions, meanwhile, was quite stable over the four-month period, and higher than for the federal government. Rural fire-fighting services had the highest level of public trust in our survey at 92.5%.
We also found a significant decline in the percentage of people who said they would vote for the Coalition if an election was held that day. This dropped from 40.4% in October 2019 to just 34.8% in January 2020 – nearly even with those who said they would vote for Labor in January (33.4%).
Significant increase in concern over global warming
We also tracked significant changes in people’s attitudes towards the environment.
For instance, 49.7% of people reported the environment as one of the top two issues facing Australia in January 2020, compared to 41.5% of respondents in October 2019.
Another interesting finding: 10.2% reported fires, natural disasters or extreme weather as the most or second-most important issue facing Australians, up from nearly nonexistent in October 2019.
Our findings showed consistently higher concern among Australians when it comes to specific environmental issues. Comparing responses from our January 2020 survey and a 2008 ANUpoll, we saw two large increases in concern for loss of native vegetation, animal species or biodiversity (13 percentage points) and drought and drying (nine percentage points).
There was an even larger increase in the proportion of people who believe global warming or climate change will impact their lives.
Nearly three-quarters (72.3%) of respondents said global warming was a very serious or fairly serious threat, a substantial increase from the 56% who said so in 2008.
The majority of those living in capital cities said they felt global warming was a very serious problem (62%) or a threat (74.9%). Perhaps even more surprising, however, was the fact these views were shared by people in non-capital cities (52% said it was very serious, 65.5% said it was a threat).
Support for new coal mines has also declined sharply over the past eight months. In our January survey, 37% of respondents said the government should allow the opening of new coal mines, down from 45.3% in an <a href="https://dataverse.ada.edu.au/dataverse.xhtml?alias=CSES">ANU survey</a> from June 2019.
While being exposed to the bushfires appears to have made people more aware of environmental issues, the drop in support for new coal mines does not appear to have been driven by the crisis itself. Rather, it appears to be consistent across the population, with the biggest decline occurring among those who voted for the Coalition in the 2019 federal election (57.5% supported new mines in January 2020, down from 71.8% in June 2019).
There is still much work to be done to fully understand people’s attitudes towards climate change and how this correlates with natural disasters like bushfires.
But the data in our survey provide opportunities for future research and new insights and will be made available through the Australian Data Archive. Future surveys could test for changes in people’s attitudes taking into account different variables and track how those attitudes change over time.<img src="https://counter.theconversation.com/content/131672/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important; text-shadow: none !important;">

GUEST OBSERVATION
During a heatwave in late 2018, Cairns temperatures topped 35°C nine days in a row and sensors at some points in the CBD recorded 45°C. <a href="https://theconversation.com/profiles/taha-chaiechi-106267"> </a>
Some <a href="https://www.un.org/en/ecosoc/integration/pdf/fact_sheet.pdf" target="_blank">60% of the planet’s expected urban area by 2030</a> is yet to be built. This forecast highlights how rapidly the world’s people are becoming urban. Cities now occupy about 2% of the world’s land area, but are home to about <a href="/news">55% of the world’s people</a> and generate more than <a href="http://nua.unhabitat.org/details1.asp?ProjectId=33&amp;ln=1" target="_blank">70% of global GDP</a>, plus the associated <a href="https://www.un.org/en/climatechange/cities-pollution.shtml" target="_blank">greenhouse gas emissions</a>.
So what does this mean for people who live in the tropical zones, where <a href="https://www.sciencemag.org/news/2014/06/expanding-tropics-will-play-greater-global-role-report-predicts" target="_blank">40% of the world’s population lives</a>? On current trends, this figure will rise to 50% by 2050. With <a href="https://sustainabledevelopment.un.org/content/documents/974736_Ziembicki%20et%20al._Implications%20of%20an%20expanding%20and%20intensifying%20tropical%20zone%20for%20the%20sustainable%20development%20agenda.pdf" target="_blank">tropical economies growing some 20% faster</a> than the rest of the world, the result is a swift expansion of tropical cities.

Population and number of cities of the world, by size class, 1990, 2018 and 2030. 
The populations of these growing tropical cities already experience high temperatures made worse by high humidity. This means they are highly vulnerable to extreme heat events as a result of climate change.
For example, extremely hot weather overwhelmed Cairns last summer. By December 3 2018, the city had recorded temperatures above 35°C nine days in a row. Four consecutive days were above 40°C.

Cairns’ heatwave summer. Authors, using BOM temperature data
For our research, temperature and humidity sensors were strategically placed in the Cairns CBD to represent people’s experience of weather at street level. These recorded temperatures consistently higher than the Bureau of Meteorology (BoM) recordings, reaching 45°C at some points.

Local effects magnify heatwave impacts
Urban environments in general are hotter than non-urbanised surroundings that are covered by vegetation. The trapping of heat in cities, known as the <a href="https://www.nationalgeographic.org/encyclopedia/urban-heat-island/" target="_blank">urban heat island</a> effect, has impacts on human health, animal life, social events, tourism, water availability and business performance.
The urban heat island effect intensifies the impacts of increasing heatwaves on cities as a result of climate change.
<a href="https://images.theconversation.com/files/291226/original/file-20190906-175678-la15cl.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/291226/original/file-20190906-175678-la15cl.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt=""></a>

But it is important to remember that other local factors also influence these impacts. These include the scale, shape, materials, composition and growth of the built environment in a particular location and its surrounding areas.
The differences between the BoM data recorded at Cairns airport and the inner-city recordings show the impacts of urban expansion patterns, built form and choice of materials in tropical cities.
The linear layout of Cairns has, on one hand, enabled the formation of attractive places for commercial activities. As these activity centres evolve into focal points of urban life, they in turn influence all sorts of socioeconomic parameters.
On the other hand, the form the built environment takes changes the patterns of wind, sun and shade. These changes alter the urban <a href="https://theconversation.com/city-temperatures-and-city-economics-a-hidden-relationship-between-sun-and-wind-and-profits-116064" target="_blank">microclimate</a> by trapping heat and slowing or channelling air movements.
<img src="https://images.theconversation.com/files/289318/original/file-20190825-170910-sjsrqt.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="">
The layout and structures of Cairns CBD alter local microclimates by trapping heat and altering air flows.
Shifting the focus to the tropics
To date, a large body of research has explored the undesired consequences of climate change and urban heat islands. However, the focus has been on capital and metropolitan cities with <a href="https://link.springer.com/article/10.1007/s00704-015-1703-8" target="_blank">humid continental climates</a>. Not many studies have looked at the economic and social impacts in the tropical context, where hot and humid conditions create extra heat stress.
Add the combined effects of climate change and urban heat islands and what are the socio-economic consequences of heatwaves in a tropical city like Cairns? We see that climate change adds another dimension to the relationship between cities, economic growth and development.
This presents a huge opportunity to start thinking about building cities that are not superficially greenwashed, but which instead tackle pressing issues such as climate variability and create sustainable business and social destinations.
In cold climates, heatwaves and urban heat islands are not necessarily undesired, but their negative impacts are more obvious and harmful in warmer climates. And these harmful impacts of heatwaves on our economy, environment and society are on the rise.
We have scientific evidence of the increasing length, frequency and intensity of heatwaves. The number of record hot days in Australia has <a href="https://www.climatecouncil.org.au/uploads/9901f6614a2cac7b2b888f55b4dff9cc.pdf" target="_blank">doubled in the past five decades</a>.

What are the costs of heatwaves?
Increased exposure to heatwaves amplifies the adverse economic impacts on industries that are reliant on the health of their outdoor workers. This is in addition to the extreme heat-related fatalities and health-care costs of heatwave-related medical emergencies. As a <a href="https://www.nccarf.edu.au/localgov/resources/protecting-human-health-and-safety-during-severe-and-extreme-heat-events-national" target="_blank">PwC report to the Commonwealth</a> on extreme heat events stated:
Heatwaves kill more Australians than any other natural disaster. They have received far less public attention than cyclones, floods or bushfires — they are private, silent deaths, which only hit the media when morgues reach capacity or infrastructure fails.
Heat also has direct impacts on economic production. A <a href="https://www.researchgate.net/publication/45660010_Temperatures_and_cyclones_strongly_associated_with_economic_production_in_the_Caribbean_and_Central_America" target="_blank">2010 study</a> found a 1°C increase resulted in a 2.4% reduction in non-agricultural production and a 0.1% reduction in agricultural production in 28 Caribbean-basin countries. Another <a href="https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2099798" target="_blank">study in 2012</a> found an 8% weekly loss of production when the temperature exceeded 32°C for six days in a row.
The 2017 <a href="http://www.agriculture.gov.au/abares/research-topics/climate/farm-performance-climate" target="_blank">Farm performance and climate</a> report by the <a href="http://www.agriculture.gov.au/abares" target="_blank">Australian Bureau of Agricultural and Resource Economics and Sciences (ABARES)</a> states:
"The recent changes in climate have had a significant negative effect on the productivity of Australian cropping farms, particularly in southwestern Australia and southeastern Australia."

It’s not just farming that is vulnerable. A <a href="/news">Victorian government report</a> report this year estimated an extreme heatwave event costs the state’s construction sector A$103 million. The impact of heatwaves on the city of Melbourne’s economy is estimated at A$52.9 million a year on average.

According to this report, economic costs increase exponentially as the severity of heatwaves increases. This has obvious implications for cities in tropical regions.
As the next step in <a href="https://www.researchgate.net/project/Evidence-based-Economic-Assessment-of-Urban-Comfort" target="_blank">our research</a>, we are examining the relationship between local urban features, urban heat islands, the resulting city temperatures and their direct and indirect (spillover) effects on local and regional economic activities.

Urban growth, heat islands, humidity, climate change: the costs multiply in tropical cities: James Cook University

One of the problems with cars is the pollution they cause.
This not only impacts the world through greenhouse gas emissions but also has an impact on the health of residents living in areas with poor air quality, according to the latest Secret Agent report.
One of the main obvious benefits of restricted car use in our cities is less congestion.
Taking cars and street parking away means that there is more room for public amenity.
This includes wider footpaths as well as more room for plants and green space. This can also lead to beneficial health effects.
If more people are out and about walking and spending time in green spaces, rather than in their car, home or office, there are more opportunities for social interaction.
This is important because social isolation is a risk factor for physical and mental illness.
Another benefit noted by the report was that: "With less cars in the area it can be expected that there will be fewer fatalities caused by traffic accidents."
In terms of property value, more green space, safer streets and less traffic are also positive features.
Improved public realm and amenity can increase the desirability of a particular area.
This combined with population growth, will increase demand and property prices will likely go up, according to the report.

GUEST OBSERVER
When you think of Antarctica, you probably picture vast, continuous ice sheets and glaciers, with maybe a penguin or two thrown in.
Yet most Antarctic plants and animals live in the permanently ice-free areas that cover about 1 percent of the continent. Our new research predicts that these areas could grow by a quarter during this century, with mixed prospects for the species that currently live there. 
Besides everyone’s favourite Emperor and Adélie penguins, terrestrial Antarctic species also include beautiful mosses, lichens, two types of flowering plants, and a suite of hardy invertebrates such as nematodes, springtails, rotifers and tardigrades, many of which are found nowhere else on Earth. Tardigrades – tiny creatures sometimes nicknamed “waterbears” – are so tough they can survive in space.
Antarctica’s ice-free areas are currently limited to a scattering of rocky outcrops along the coastline, or cliff faces, or the tops of mountain ranges. They form small patches of suitable habitat in a huge sea of ice, much like islands. 
As a result, the plants and animals that live there are often isolated from each other. But as Antarctica’s climate warms, we expect ice-free areas to get bigger and eventually start joining up. This would create more habitat for native species, but also new opportunities for non-native species to spread. 
Our study, published today in Nature, forecasts that climate change will expand Antarctica’s ice-free areas over the course of this century. Under the most severe scenario that we modelled (which is also the one on which the globe is currently tracking), more than 17,000 square km of new ice-free area could emerge across the continent by 2100. 
This would increase the current total ice-free area by nearly a quarter. The majority of this new ice-free land will be on the Antarctic Peninsula, which could have three times as much ice-free area as it does today.  
Brave new world
As the ice-free areas expand, the distances between them will decrease, giving plants and animals more opportunity to spread through the landscape. On the Antarctic Peninsula, which has already warmed more than anywhere else in Antarctica, many of the ice-free patches will expand so much that they will start joining together.
Will this increase in habitat availability benefit the plants and animals that live there? It will definitely provide new opportunities for some native plants and animals to expand their range and colonise new areas. The warming climate may also give a boost to species that are currently hampered by the lack of warmth, nutrients and water. Some Antarctic mosses, for example, are expected to grow faster as temperatures rise, and Antarctica’s two flowering plant species are already expanding southward.
However, the potential benefits seem likely to be outweighed by the negatives. The joining-up of habitat patches could allow species that have been isolated for much of their evolutionary past to meet suddenly. If the newcomers to a particular area outcompete the native species, then it may lead to localised extinctions. Over the coming centuries this could lead to the loss of many plants and animals, and the homogenisation of Antarctica’s ecosystems.

An even bigger concern is that Antarctica’s great thaw could provide new opportunities for species to invade. Antarctica’s best bulwark against non-native species is its harsh climate and extreme weather, to which native Antarctic species have spent many thousands of years adapting. 
We already know that many plants and invertebrates are reaching Antarctica, most often in food or cargo shipments. As the climate warms, some of these non-native species may be able to establish themselves on the Antarctic Peninsula, and the increasing connectivity will allow them to easily move through the landscape. Many of these animals and plants may become invasive, competing with the native species for space and resources. 
We don’t know how Antarctica’s species will cope with the increasing competition. But if the sub-Antarctic islands provide any indication, the outlook is depressing. Australia’s World Heritage-listed Macquarie Island, for example, was severely impacted by invasive cats, rats, rabbits and mice (although it has since been declared free of these pests after an intensive eradication effort).
Several non-native species have already come to Antarctica, including the invasive annual meadowgrass Poa annua (a common weed around the world), which has colonised newly ice-free areas left behind by retreating glaciers. It is thought to outcompete Antarctica’s native plants, although we don’t yet know what the impact will be on animals. 
Humans – both scientists and tourists – are key transporters of non-native species to the continent, and tourist numbers continue to grow (almost 37,000 visited in the 2016-17 summer). 
Biosecurity is paramount for the ongoing protection of Antarctica. If bags, shoes, clothes and field equipment are not properly cleaned and inspected before arriving on the continent, then non-native seeds, microbes and insects could be transported to Antarctica and begin to spread. 
We call for protection of ice-free areas that will remain intact in a changing climate, and for the Antarctic scientific and tourism communities to pinpoint key areas where greater biosecurity and monitoring for invasive species may be needed.
