South East Queensland developer&nbsp;<a href="https://www.apartments.com.au/developers/gardner-vaughan-group">Gardner Vaughan Group</a>’s entry into the Gold Coast apartment market has progressed from pipeline to market, with its Chevron Island project Bronze on Chevron now formally available to purchase ahead of a planned 2029 completion.

The 119-apartment development on Mawarra Street marks the Brisbane-headquartered builder-developer’s first residential play in the Gold Coast, following its expansion south from Brisbane and the Sunshine Coast.

<a href="https://www.apartments.com.au/new-apartments/bronze-on-chevron-8-mawarra-street-surfers-paradise-qld-4217">Bronze on Chevron</a> comprises a mix of two-, three- and four-bedroom residences, with pricing starting from just over $1.5 million. The project is being delivered under Gardner Vaughan’s fully integrated model, with the group acting as both developer and builder, a structure it has consistently applied across its South East Queensland portfolio.

[smartcode_project:default project_id=107520 project_image_fid=367182]

Architecture has been designed by <a href="https://www.apartments.com.au/architects/cottee-parker-architects">Cottee Parker</a>, with landscape architecture by <a href="https://www.apartments.com.au/landscape-architect/jeremy-ferrier-landscape-design">Jeremy Ferrier</a>. The building presents as a single-tower scheme, with a focus on maximising outlook across both the Surfers Paradise skyline and the Nerang River.

Apartments have been planned with open-plan living zones extending to generous balconies, a response to the site’s dual-aspect positioning between river and ocean. Interiors follow a restrained coastal palette, with two colour schemes offered, and an emphasis on natural light and cross-ventilation.

[smartcode_project:default project_id=107520 project_image_fid=367181]

Resident amenity is concentrated across more than 1,250 sqm and includes a resort-style pool, gym, yoga lawn and rooftop entertaining areas. A function space with catering facilities forms part of the upper-level offering, alongside north- and south-facing outdoor areas.

Ground level will incorporate two retail tenancies, intended to extend the existing village character of the surrounding streets.

&nbsp;

[smartcode_project:default project_id=107520 project_image_fid=367200]

The project sits within walking distance of Thomas Drive’s established dining strip, while maintaining proximity to <a href="https://www.apartments.com.au/developments/surfers-paradise-qld-4217">Surfers Paradise</a> beach and broader Gold Coast amenity. The location, positioned on Chevron Island between the river and coastline, has increasingly attracted mid- to high-density development in recent years as the precinct evolves beyond its low-rise origins.

Gardner Vaughan’s move into the Gold Coast was first signalled in 2025, with the group identifying the region as a natural extension of its operations. Chief Executive Officer Simon Betteridge described the expansion as both “strategic and natural”, citing demand for well-designed apartments in lifestyle-driven markets.

Construction is expected to complete in early 2029.

Ellipse sets Castle Hill apartment record with $5.75 million Lily Lane penthouse sale

Fresh off completing its Delano Crows Nest development, Lindsay Bennelong has lodged plans for its next project, this time turning its attention back to the beach.

The developer, started 20 years ago by Clarendon Homes founder Peter Campbell, is proposing a 37-apartment scheme at <a href="https://www.apartments.com.au/new-apartments/17-25-ashburner-street-manly-nsw-2095">17-25 Ashburner Street</a>, Manly, positioned between the southern end of <a href="https://www.apartments.com.au/developments/manly-nsw-2095">Manly</a> Beach and East Manly Cove.

Lindsay Bennelong called on local architecture firm Platform Architects to design the new building, given their success at Finn, Lindsay Bennelong's current luxury apartment project on North Steyne.&nbsp;

According to the Design Verification Statement by Bridie Gough of Platform Architects, the proposal “relates to the current context but also the desired future character of taller buildings suitable to the new planning controls.”

The site has been identified as a Low to Mid-Rise Housing (LMR) location, given its position within 400 metres of the Manly Town Centre E1 Business Zone. The LMR controls are intended to unlock additional housing supply in well-located areas close to public transport, allowing developers to seek increased height limits to support greater density.

“The proposal seeks to provide this increased level of housing whilst being respectful of some of the smaller scale buildings also nearby,” the statement reads.

Lindsay Bennelong Development Director Leigh Manser said the project has been carefully aligned with the intent of the LMR controls. The proposal will significantly increase housing yield on the site, replacing four houses and 10 apartments, comprising 25 bedrooms, with 37 new apartments delivering a total of 94 bedrooms, whilst remaining compliant with the LMR controls.

“Sydney is in a severe undersupply, and delivering more dwellings and more bedrooms than what currently exists is exactly what the LMR policy is designed to activate,” Manser said, noting that nine of the apartments will be allocated as affordable housing for frontline workers.

“We have already commenced discussions with our community housing provider to determine the rental levels that frontline workers can realistically afford in this location,” he said. “These will need to sit well below the standard affordable housing benchmark of 20 per cent below market rent, and that has been factored into our feasibility and pricing.”

The design of the building incorporates a wave-like indentation running through the façade, referencing the nearby coastline and anchoring the building within its local context.

The&nbsp;Design Verification Statement says careful consideration has been given to the articulation of the building, ensuring the bulk is broken down to a more human scale through a defined four-storey podium."

The scheme includes a mix of one-, two- and three-bedroom apartments, as well as a full-time building manager's office and wellness facilities including a sauna and a gym.

“The design ensures a high level of amenity, with apartments offering generous private open space, many with expansive views, and all with comfortable proportions."

<a href="https://www.apartments.com.au/developers/lindsay-bennelong-developments">Lindsay Bennelong</a>&nbsp;is currently developing Finn Manly, just four full-floor luxury apartments on North Steyne. They recently welcomed residents to its 81-unit Delano Crows Nest development, a&nbsp;carefully scaled infill project designed to bridge&nbsp;<a href="https://www.apartments.com.au/developments/crows-nest-nsw-2065">Crows Nest</a>’s lively village centre with its surrounding heritage streets.

Designed by&nbsp;<a href="https://www.apartments.com.au/architects/ajc-architects">AJC Architects</a>,&nbsp;<a href="https://www.apartments.com.au/new-apartments/delano-crows-nest-27-57-falcon-street-crows-nest-nsw-2065">Delano</a>&nbsp;is arranged across three low-rise buildings, incorporating a mix of one, two, and three-bedroom apartments alongside a limited number of townhomes addressing Hayberry Lane. The architectural approach drew on the area’s Art Deco lineage, reinterpreted through contemporary detailing and framed by landscaped communal gardens.

The developer also has a development site in Maroubra.

First look: Lindsay Bennelong's new Manly apartment development revealed

Fifty-nine residences across 37 levels. No more than two per floor. With 80 per cent now sold, what remains at <a href="https://www.apartments.com.au/new-apartments/madeline-by-mosaic-broadbeach-22-mary-avenue-broadbeach-qld-4218">Madeline by Mosaic</a> is a short list.

Madeline was always conceived at a scale that sits outside the normal register of Gold Coast apartment living. The residences are half- and full-floor configurations, with the largest spanning more than 400 sqm, dimensions that place them closer to the penthouse end of the market regardless of where they sit in the building.

That scale is the organising principle of everything else: how the floorplans are laid out, how the materials read, how the connection between inside and outside works.

[smartcode_project:default project_id=150135 project_image_fid=355941]

The interiors were developed in collaboration with <a href="https://www.apartments.com.au/architects/fraser-partners-0">Fraser &amp; Partners</a>, the architecture practice&nbsp;<a href="https://www.apartments.com.au/developers/mosaic-property-group">Mosaic</a> brought in as design partner for the first time on this project. The palette runs to natural stone, textured timbers, and soft metallics, materials chosen as much for their tactile quality as their appearance.

Light cleverly shifts across surfaces through the day, and the design is explicit about wanting that to be noticed. Full-height glazing runs across the primary living areas, and where the building faces east toward the ocean, those walls of glass are doing real work: framing a view corridor that the site's position directly opposite Broadbeach State School's playing fields keeps permanently open.

That outlook is the site's most consequential asset. In a suburb where new towers continue to rise, a protected view line is genuinely rare, and the Mary Avenue address secures it. Residents at Madeline will look out over open parkland rather than the rear of another building, a distinction that becomes more meaningful with each new development approved nearby.

[smartcode_project:default project_id=150135 project_image_fid=355939]

The private outdoor spaces are sized to match the residences themselves. Terraces on the upper levels frame uninterrupted ocean panoramas, and the planning ensures that living areas extend into those outdoor zones rather than treating them as separate attachments. The flow between the two is part of the design intent, not an afterthought.

Inside, the finish specification reflects the same approach. Rich stone benchtops, warm timber joinery, bespoke hardware, each element specified to hold up over time rather than read as a moment in a particular trend cycle.

[smartcode_project:default project_id=150135 project_image_fid=3409]

Beyond the residences, the amenity offering extends that register. A lap pool and sun deck anchor the outdoor space, alongside a magnesium pool, cold plunge, steam room, and sauna.

A commercial-grade gymnasium, residents' lounge, library, and boardroom round out a programme that functions more like a private members club than a standard building amenity floor.

Construction has commenced under Mosaic's in-house building arm, with completion scheduled for late 2028.

Madeline by Mosaic delivers penthouse-level living across every apartment

Developer Fortezza Group is the latest to take its new apartment development, <a href="https://www.apartments.com.au/new-apartments/the-belvedere-5-7-church-street-nelson-bay-nsw-2315">The Belvedere in Nelson Bay</a>, to the NSW Government.

Fortezza, predominantly a South East Queensland developer, is the latest to apply for State Significant Development&nbsp; status through the NSW Government's Housing Delivery Authority, a pathway becoming favoured by developers to speed up the approval process.

They are planning 57 two- and three-bedroom apartments across 5-7 Church Street and 42 Donald Street, near d'Albora Nelson Bay Marina. The diverse apartment mix has sizes from just over 80 sqm to the largest three-bedroom penthouses that reach nearly 200 sqm.

<img alt="Fortezza" data-entity-type="file" data-entity-uuid="090360e1-66d7-43ad-b686-aba81f173bf2" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-04-29%20at%2010.22.40%E2%80%AFAM.png?VersionId=DMqF96eBZolqSAAAcugX0l66ueWng66m" />

Fortezza calls the project a "piece of Istria in Nelson Bay,"&nbsp;referring to the largest peninsula in the Adriatic Sea, shared by Croatia (90%), Slovenia, and Italy, which is known for its Roman history, Venetian-style coastal towns and inland hilltop villages.

They say the The Belvedere is strategically positioned at the apex of Nelson Bay, offering unrivalled views of the ocean, the bay and captivating topography of the area.

"Our commitment to maintaining the integrity of every view and sight line has been relentless," Fortezza Group says.

"Through extensive modelling and analysis, we ensure that each apartment enjoys the natural beauty of Nelson Bay, regardless of future developments. Each design element is carefully curated to harmonise with our European heritage, drawing profound inspiration from the Roman architectural marvels in Istria. The arches, the cascades of greenery and the stonework that define our project pay homage to the structures that once exemplified Roman grandeur."

Residents will have access to a pool, communal green spaces, an office and a coffee shop.

GUEST OBSERVATION
Victoria has some of the most <a href="https://www.propertyobserver.com.au/https://www.pnas.org/content/106/28/11635" target="_blank">carbon-dense native forests</a> in the world. Advocates for logging these forests <a href="http://www.naturallybetter.com.au/carbon-and-environment" target="_blank">often argue</a> that wood products in buildings and furniture become long-term storage for carbon.
However, these claims are misleading. Most native trees cut down in Victoria become woodchips, pulp and pallets, which have short lifespans before going to landfill. In landfill, the wood breaks down and releases carbon back into the atmosphere.
On the other hand, our <a href="https://www.theguardian.com/environment/2019/mar/28/common-sense-littleproud-backs-victoria-plan-to-exit-logging-to-earn-carbon-credits" target="_blank">evolving carbon market</a> means Australia’s native forests are extremely valuable as long-term carbon stores. It’s time to recognise logging for short-lived wood products is a poor use of native forests.
The problem with logging native forests
Victoria has about 7.6 million hectares of <a href="http://www.agriculture.gov.au/abares/research-topics/forests/forest-data#australian-forest-and-wood-products-statistics" target="_blank">native forests</a>. The most <a href="https://www.propertyobserver.com.au/https://www.pnas.org/content/106/28/11635" target="_blank">carbon-dense</a> areas are in ash forests, consisting of mountain ash, alpine ash and shining gum trees.
These forests can store up to 1,140 tonnes of carbon per hectare <a href="https://www.sciencedirect.com/science/article/pii/S0378112704001343" target="_blank">for centuries</a>.
But around 1.82 million hectares of <a href="http://www.gazette.vic.gov.au/gazette/Gazettes2014/GG2014S405.pdf" target="_blank">Victorian native forests</a> are allocated to the government’s logging business, VicForests.
VicForests <a href="http://www.vicforests.com.au/static/uploads/files/report-vicforests-annual-report-2018-wfccxhsjgpfj.pdf" target="_blank">claims</a> logging is the only market for the large area of native forest allocated to it. In other words, its forests are exclusively valued as timber asset, in the same way a wheat crop would be exclusively valued for wheat grain production.
In Victorian native forests, industrial scale clearfell logging removes around <a href="https://esajournals.onlinelibrary.wiley.com/doi/full/10.1890/ES14-00051.1" target="_blank">40% of the forest biomass</a> for logs fit for sale.
The remaining 60% is debris, which is either burned off or decomposes – becoming a <a href="https://esajournals.onlinelibrary.wiley.com/doi/full/10.1890/ES14-00051.1" target="_blank">major source</a> of greenhouse gas emission.
Myth one: storing carbon in wood products
The first myth we want to address is logging native forests is beneficial because the carbon is stored in wood products. This argument depends on the proportion of forest biomass ending up in wood products, and how long they last before ending up in landfill.
On average, logs suitable to be sawn into timber make up only an average <a href="http://www.agriculture.gov.au/abares/research-topics/forests/forest-data#australian-forest-and-wood-products-statistics" target="_blank">35% of total logs</a> cut from Victorian native forests.
Of this 35%, sawmills convert <a href="http://www.vafi.org.au/wp-content/uploads/2015/06/vafi_investment_innovation_report2012.pdf" target="_blank">less than 40%</a> into sawn timber for building and furniture. Offcuts are woodchipped and pulped for paper manufacturing, along with sawdust sold to <a href="https://www.timberbiz.com.au/chickens-in-a-flap-over-heyfield/" target="_blank">chicken broiler sheds</a> for bedding.
Sawn timber equates to 14% of log volume cut from the forest. The remaining 84% of logs cut are used in short-lived and often disposable products like copy paper and pallets.
The lifespan of paper products is assumed to be <a href="https://web.archive.org/web/20061019205713/http://www.greenhouse.gov.au/ncas/reports/tech08" target="_blank">three years</a>. Although around <a href="https://www.sustainability.vic.gov.au/Government/Victorian-Waste-data-portal/Interactive-waste-data-mapping/Waste-projection-model" target="_blank">75% of paper and cardboard </a>is recovered, recycling is growing more <a href="https://www.theage.com.au/politics/victoria/state-government-must-act-to-fix-recycling-crisis-councils-urge-20190222-p50zos" target="_blank">uncertain</a> with recovered paper being sent to landfill.
The maximum lifespan of a timber pallet is <a href="http://vta.com.au/wp-content/files_mf/1505108242PalletSurveyReport2017.pdf" target="_blank">seven years</a>. At the end of their service, <a href="https://www.sciencedirect.com/science/article/pii/S2212827115000852" target="_blank">timber pallets</a> are sent to landfill, chipped for particleboard, reused for landscape mulch or burnt for energy generation.
Longer-lived wood products, such as the small proportion of native timber used in building and furniture, have a lifespan of around <a href="https://web.archive.org/web/20061019205713/http://www.greenhouse.gov.au/ncas/reports/tech08" target="_blank">90 years</a>. These wood products are used to justify logging native forests.
But at the end of their service life, the majority of these wood products also end up in landfill.
In fact, for the 500,000 tonnes of wood waste generated annually from building, demolition and other related commercial processes in Victoria, over two thirds end up in landfill, according to a Sustainability Victoria <a href="http://www.sustainability.vic.gov.au/-/media/resources/documents/publications-and-research/research/market-analysis/market-analysis-timber-sept-2014-pdf.pdf" target="_blank">report</a>.
Myth two: the need to log South East Asian rainforests
A second myth is using logs from Victorian native forests will prevent logging and degradation of rainforests across South East Asia, particularly for <a href="https://www.fwpa.com.au/images/resources/Amended_Final_report_C_native_forests_PNC285-1112.pdf" target="_blank">paper production</a>.
This is patently absurd. The wood from the Victorian plantation sector – essentially timber farms, rather than trees growing “wild” in native forests – could replace native forest logs used for paper manufacturing in Victoria several times over.
In fact, in 2016-17 89% of logs used to make wood pulp (pulplogs) for paper production in Victoria <a href="http://www.agriculture.gov.au/abares/research-topics/forests/forest-data#australian-forest-and-wood-products-statistics" target="_blank">came from plantation trees</a>, with the majority of hardwood logs exported.
And Australia is a <a href="http://www.agriculture.gov.au/SiteCollectionDocuments/abares/afwps-overview-mar-jun-2018.pdf" target="_blank">net exporter</a> by volume of lower-value unprocessed logs and woodchips.
Processing pulplogs from <a href="https://au.fsc.org/en-au" target="_blank">well managed</a> plantations in Victoria instead of exporting them would give a much needed jobs boost for local economies.
With most of these plantations established on previously cleared farmland, they offer one of the most robust ways for the land use sector to <a href="https://publications.csiro.au/rpr/download?pid=csiro:EP113280&amp;dsid=DS6" target="_blank">off-set greenhouse gas emissions</a>.
Next steps
The time is right for Australian governments to develop a long-term carbon storage plan that includes intact native forests.
Logging results in at least 94% of a forest’s stored carbon ending up in the atmosphere. A maximum of 6% of its carbon remains in sawn timber, for up to 90 years (but typically much shorter). This is patently counterproductive from a carbon-storage point of view.
State-owned forest management companies, such as VicForests, can transition away from the timber business and begin managing forests for carbon storage. Such a concept is not new – the federal government has <a href="https://www.legislation.gov.au/Details/F2017L01038/Explanatory%20Statement/Text" target="_blank">already approved</a> a way to value the carbon storage of plantations.
The same must now be developed to better protect native forests and the large amounts of carbon they can store.<img src="https://counter.theconversation.com/content/115054/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 OBSERVER
Land clearing is on the rise in Queensland and New South Wales, with land clearing laws being fiercely debated.
In Queensland in 2013–14, 278,000 hectares of native vegetation were cleared (1.2 times the size of the Australian Capital Territory). A further 296,000ha were cleared in 2014–15. These are the highest rates of deforestation in the developed world.
Land clearing on this scale is bad for a whole host of reasons. But our research shows that it is also likely to make parts of Australia warmer and drier, adding to the effects of climate change.
<h2>How do trees change the climate?</h2>
Land clearing releases greenhouse gases into the atmosphere, but the effect of land clearing on climate goes well beyond carbon emissions. It causes warming locally, regionally and even globally, and it changes rainfall by altering the circulation of heat and moisture.
Trees evaporate more water than any other vegetation type – up to 10 times more than crops and pastures. This is because trees have root systems that can access moisture deep within the soil. Crops and pastures have 70% of their roots in the top 30cm of the soil, while trees and other woody plants have 43% of their roots in the deeper part of the soil.
The increased evaporation and rough surface of trees creates moist, turbulent layers in the lower atmosphere. This reduces temperatures and contributes to cloud formation and increased rainfall. The increased rainfall then provides more moisture to soils and vegetation.
The clearing of deep-rooted native vegetation for shallow-rooted crops and pastures diminishes this process, resulting in a warmer and drier climate.
We can see this process at work along the “bunny fence” in southwest Western Australia, where there is a moister atmosphere and more clouds over native vegetation compared with nearby farming areas during summer.
Studies in Amazonia also indicate that as deforestation expands rainfall declines. A tipping point may be reached when deforestation reaches 30-50%, after which rainfall is substantially reduced. Complete deforestation results in the greatest decline in rainfall.
<h2>More trees, cooler moister climate</h2>
We wanted to know how land clearing could affect Australia’s climate in the future. We did this by modelling two scenarios for different amounts of land clearing, using models developed by CSIRO.
In the first scenario, crops and pasture expand in the semi-arid regions of eastern and southwest Australia. The second scenario limits crops and pastures to highly productive lands, and partially restores less productive lands to savanna woodlands.
We found that restoring trees to parts of Australia would reduce surface temperatures by up to 1.6℃, especially in western Queensland and NSW.
We also found that more trees reduced the overall climate-induced warming from 4.1℃ to 3.2℃ between 2050 and 2100.
Replanting trees could increase summer rainfall by 10% overall and by up to 15.2% in the southwest. We found soil moisture would increase by around 20% in replanted regions.
Our study doesn’t mean replanting all farmed land with trees, just areas that are less productive and less cost-effective to farm intensively. In our scenario, the areas that are restored in western Queensland and NSW would need a tree density of around 40%, which would allow a grassy understorey to be maintained. This would allow some production to continue such as cattle grazing at lower numbers or carbon farming.
<h2>Political and social challenges</h2>
Limiting land clearing represents a major challenge for Australia’s policymakers and farming communities.
The growing pressure to clear reflects a narrow economic focus on achieving short- to medium-term returns by expanding agriculture to meet the growing global demand for food and fibre.
However, temperatures are already increasing and rainfall is decreasing over large areas of eastern and southwest Australia. Tree clearing coupled with climate change will make growing crops and raising livestock even harder.
Balancing farming with managing climate change would give land owners on marginal land new options for income generation, while the most efficient agricultural land would remain in production. This would need a combination of regulation and long-term financial incentives.
The climate benefits of limiting land clearing must play a bigger part in land management as Australia’s climate becomes hotter and drier. Remnant vegetation needs to be conserved and extensive areas of regrowth must be allowed to regenerate. And where regeneration is not possible, we’ll have to plant large numbers of trees.

Stopping land clearing and replanting trees could help keep Australia cool in a warmer future

GUEST OBSERVER
We are living in the most explosive era of infrastructure expansion in human history. The G20 nations, when they met in Australia in 2014, argued for between US$60 trillion and US$70 trillion in new infrastructure investments by 2030, which would more than double the global total value of infrastructure.
Some of the key players in this worldwide infrastructure boom are huge investors such as the World Bank. The past few years and decades have seen the rise of major new investment banks, such as the recently founded Asian Infrastructure Investment Bank (AIIB), and the dramatic growth of funds such as the Brazilian Development Bank (BNDES).
The new banks, along with traditional big lenders such as the World Bank, the International Monetary Fund, and the Asian, African, and Inter-American Development Banks, are very fond of funding big infrastructure such as roads, dams, gas lines, mining projects, and so on.
Some people had hoped that these banks would promote sustainable and socially equitable development, but it now seems that they could end up doing precisely the opposite.
<h2>The infrastructure tsunami</h2>
The next few decades are expected to see some 25 million km of new paved roads, thousands more hydroelectric dams, and hundreds of thousands of new mining, oil and gas projects.
The environmental impacts of the modern infrastructure tsunami could easily dwarf climate change and many other human pressures, as thousands of projects penetrate into the world’s last surviving wild areas. Roughly 90 perch t of the new projects are in developing nations, often in the tropics or subtropics which harbour the planet’s biologically richest and environmentally most critical ecosystems.
In these contexts, new infrastructures such as roads can open a Pandora’s box of environmental problems, by promoting widespread deforestation, habitat fragmentation, poaching, fires, illegal mining and land speculation.
For instance, our research in the Brazilian Amazon has shown that 95 percent of all deforestation occurs within 5.5 km of a legal or illegal road.
In Brazil, 12 new dams planned for the Tapajós River (and their associated road networks) are expected to increase Amazon deforestation by nearly a million hectares. Across the Amazon, more than 330 dams are now planned or under construction.
In the Congo Basin, an avalanche of new logging roads has opened up vast areas of rainforest to poachers armed with rifles and cable snares. As a result, the past decade has seen two-thirds of all Forest Elephants slaughtered for their valuable ivory tusks.
<h2>Fears of fast-tracking</h2>
Brazil’s BNDES has been heavily criticised for funding scores of environmentally and socially harmful projects, such as mega-dams in the Amazon. Fears were raised that China’s AIIB would behave similarly, especially when it announced that it would be using “streamlined” procedures for evaluating its projects.
Such fast-tracked procedures would differ from those used by other major lenders such as the World Bank, which after years of criticism have gradually implemented measures designed to limit the environmental and social impacts of its projects. Even these safeguards are often inadequate, as I and others argued in a recent article, but at least they are a big improvement over past practices.
When China opened up its AIIB to other countries, 30 nations initially joined as founding members. Many of these are western economies, including the United Kingdom, Germany, France, Italy, Norway, Australia and New Zealand.
At the time, many observers hoped that the bank’s broader membership would encourage the AIIB to moderate its hard-charging stance — perhaps fostering environmental and social safeguards more akin to those of the existing major lenders.
<h2>Race to the bottom?</h2>
But in fact the exact opposite appears to be happening. Rather than the AIIB raising its game, the World Bank recently concluded a review of its environmental standards — a move that has been criticised as weakening its environmental and social safeguards.
It is doing so, it says, in order to keep up with “new and varied development demands”. This is widely seen as a response to increasing competition with other investors such as the AIIB.
What will this mean? The global economy has slowed for the moment, giving environmental planners a tiny window of breathing space. But make no mistake, the infrastructure tsunami is still happening. If the global economy rebounds to a degree, the feeding frenzy of projects seen in recent years could easily return.
This could be bad news for the global environment and socially disempowered peoples. For instance, a 2009 analysis found that many developing nations had become “pollution havens” for projects funded by China or Chinese investors, who were attracted to nations with weak environmental controls. Notably, other advanced (OECD) economies showed no such tendency. 
Will other major lenders follow suit? Will there simply be a “race to the bottom” among big lenders in order to remain competitive? Only time will tell.
The other key question revolves around the role of western nations that are parties to the AIIB, such as the EU members and Australia. Do they have enough influence and determination to make a difference? With China, India and Russia holding the biggest shares of the bank’s capitalisation, it’ll be an uphill battle.
Right now, for the environment and human rights, the signs are all pointing in the wrong direction.
