Midway through the COP29 climate summit in Baku last November, a number of prominent figures signed an open letter calling for “fundamental reform” of how COPs work. As currently structured, they said, COPs “simply cannot deliver the change at exponential speed and scale”.
The letter put forward several proposals, like imposing eligibility criteria on COP hosts and streamlining the negotiations, adding to a heated ongoing debate about the COP process. But it ignored the most fundamental and potentially impactful reform of all: to finally introduce a voting role for the climate negotiations.
The COP process is clearly failing to take ambitious decisions commensurate with the urgency of the climate challenge. Failure at COP25 to welcome the Intergovernmental Panel on Climate Change’s special report on 1.5˚C; at COP28 to clearly acknowledge that fossil fuels need to be phased out; and at COP29 to make any advance at all on mitigation, are just some of the latest examples.
But all those concerned about the credibility, integrity, and effectiveness of international action on climate change need to be clear as to where the obstacles to strong decision-making lie. These are not primarily to do with organisational flaws in the COP process that minor reforms could address, but rather, with the blanket requirement for consensus decision-making and the obstruction resulting from it.
This stems from an act of sabotage committed at the very first COP talks in Berlin in 1995, when fossil fuel-exporting governments, notably Saudi Arabia and Kuwait, supported by allied lobby groups – in particular the US-based Climate Council and Global Climate Coalition (GCC) – blocked what should have been the routine adoption of voting rules.
The resulting default practice of consensus conferred outsize influence on very small blocking minorities of countries, who regularly water down decisions by threatening to obstruct. The result, year after year, is that the voices of the large majority of more ambitious parties fail to be reflected in the decisions of the COP. As Fiji said at COP29, “we are continuously asked to ignore our needs”.
Requiring consensus, without a clear definition, also makes for arbitrary, messy and inconsistent decision-making, overly reliant on the (sometimes dubious) judgement of the COP president. At COP28, the most high-profile decision – the Global Stocktake – was taken without small island developing states (AOSIS) in the room. At COP29, the talks’ president, Mukhtar Babayev, banged his gavel to adopt the NCQG finance goal without even looking up to see if there were objections. These incidents are testimony to the flaws of the status quo.
In this context, by far the most impactful reform would be to introduce carefully crafted voting rules. Ideally, these would require either a super-majority (seven-eighths of nations, for example), or a double-majority of developed and developing countries (especially for finance decisions). Dissenters could be listed in a footnote if they wished.
This would almost certainly have allowed much stronger language to be adopted throughout the history of the negotiations, not least at the last four COPs, sending a more powerful signal to decision-makers worldwide and in all sectors about the ambitious direction of international climate policy.
Introducing a voting rule in this way, even just for certain decisions, would be resisted tooth and nail by those who have long profited from the status quo. A broad progressive coalition cutting across political groupings would be needed to explore legal avenues for doing so, most likely amending the 1992 United Framework Convention on Climate Change (which can be done by a vote).
Pursuing such a momentous reform would involve an epic battle with those who have so effectively obstructed the negotiations since the beginning. But for the ambitious, the vulnerable, and all those who genuinely want to prevent dangerous anthropogenic climate change, it is a COP reform proposal that would definitely be worth fighting for.

What if Australia’s worst offshore oil spill hasn’t happened yet?
I’m terrified by the thought.
Our new report in partnership with Environs Kimberley analyses Woodside’s own oil spill modelling and it reveals a worst-case blowout at the corporation’s proposed Browse gas project at Scott Reef could be up to 30 times larger than the Montara oil spill – one of Australia’s worst environmental disasters to date.
Woodside’s own modelling warns that oil pollution could spread across Scott Reef, the Kimberley coast and beyond, with impacts Woodside itself describes as “severe”, “potentially irreversible” and “catastrophic”.
What’s at stake?
Scott Reef really is like nowhere else on Earth.
Scott Reef is Australia’s largest freestanding oceanic reef, a pristine marine ecosystem that has thrived for around 15 million years. About 270 kilometres off the Kimberley coast, it supports more than 2,000 marine species, including endangered pygmy blue whales, nesting green sea turtles, the endangered dusky sea snake and ancient corals.
Yet Woodside wants to drill up to 57 toxic wells around and underneath it, causing decades of deafening seismic blasting, light and noise pollution, shipping traffic and, of course, the risk of a ‘catastrophic’ oil spill.
What did Woodside’s modelling find?
Before Browse can be approved, Woodside is required to assess what could happen if something goes wrong. We analysed the corporation’s own environmental assessment documents, and the findings are deeply concerning.
Woodside’s modelling shows that the most severe Browse scenario would be the worst oil spill in Australian history, releasing up to 893,739 barrels of condensate into the Timor Sea. For context, the Montara oil spill released 30,000 barrels of oil.
A blowout of this scale could see oil spread hundreds of kilometres, reaching some of Australia’s most important marine environments, extending into Indonesian and Timor-Leste waters and even washing up along parts of the Kimberley coast. Entrained oil – oil mixed throughout the water column – is predicted to travel up to 863 kilometres from the spill site.
The modelling identifies potential impacts to at least nine marine parks, eight reefs and three Indigenous Protected Areas, as well as important habitats for endangered species, including pygmy blue whales, green sea turtles, seabirds and other marine life.
These aren’t just places on a map. They are globally significant marine ecosystems that support ancient coral reefs, endangered wildlife, tourism, fisheries and coastal communities. A spill of this scale wouldn’t simply affect one reef; it has the potential to impact an entire connected marine ecosystem.
Why this matters now
The most important thing is that Browse has not yet been approved. That means there is still time to stop Browse and the serious risks outlined in Woodside’s own modelling.
The science has been done. The risks have been modelled. The decision now rests with the Australian Government.
Governments are often forced to respond after environmental disasters happen. This is one of those rare moments where they have the opportunity to act before one does.
What you can do
Together, we still have the power to stop Woodside and save Scott Reef.
You can help by:
- Sending an email to Environment Minister Murray Watt and Prime Minister Anthony Albanese, calling on them to reject Browse.
- Sharing this story to help more Australians understand what’s at stake.
- Encouraging your friends and family to take action.
The more people who support saving Scott Reef, the harder it is for governments to approve Woodside’s drilling plans – Browse.
Together, we can ensure a reef that has existed for millions of years is known for its incredible biodiversity – not as the site of Australia’s worst oil spill.
Let’s save Scott Reef.
What if Australia’s worst offshore oil spill hasn’t happened yet?
Analysis by Greenpeace and Environs Kimberley shows that a severe oil spill at Scott Reef could be the worst in Australian history — Woodside has labeled the impact of such a spill ‘catastrophic’.
According to the fossil fuel company the impacts to Scott Reef ‘would likely be severe and potentially irreversible’. Oily pollution could reach as far as the Kimberley coast to the coasts of Indonesia and Timor Leste while endangered marine species live, breed, forage and migrate within the potential disaster zone: whales, seabirds, turtles and other marine life are all at risk.
Report Summary
Woodside’s Browse drilling plans at Scott Reef have been found to pose unacceptable risks to the Western Australian environment once before. To secure their approvals under Federal and Western Australian law, Woodside has modelled a number of possible oil spill scenarios that could result from the Browse project.
Key Findings
- The most severe Browse scenario would be the worst oil spill in Australian history – up to 30 times bigger than the 2009 Montara oil spill disaster. According to Woodside, the environmental impact of such a spill would be ‘catastrophic’.
- Scott Reef and Sandy Islet could be covered in oily pollution. Woodside has conceded that the impacts to Scott Reef from a major spill ‘would likely be severe and potentially irreversible’.
- A blowout of this scale could see oil washing up on the Western Australian Kimberley Coast, and affect at least nine marine parks, eight reefs, three Indigenous Protected Areas, and several islands in Australian, Indonesian and Timor Leste waters.
- Endangered and vulnerable marine species live, breed, forage and migrate within the potential disaster zone: whales, seabirds, turtles and other marine life are all at risk.
- A Browse oil spill threatens important tourism, diving, surfing and fishing hotspots, with potential ‘long term impacts’ for tourism operators in the Kimberley or visiting Rowley Shoals or Scott Reef.
Scott Reef: An ancient oceanic reef system
Scott Reef, located around 270 kilometres off the Western Australian Kimberley coast, is one of Australia’s largest oceanic reef systems. Ancient Scott Reef has been thriving for 15 million years, having adapted to changing seas. Today, it is a haven for marine life, providing vital habitat for more than a thousand species, including corals, fish, sharks and rays.
The deep waters surrounding the reef are home to 29 known species of whale and dolphin, including endangered pygmy blue whales, which travel along the Western Australian coast and stop at Scott Reef during their annual migration to forage and feed. The dusky sea snake, also classified as endangered, lives at Scott Reef. Sandy Islet, part of Scott Reef, is a nesting ground for a small population of genetically distinct green sea turtles, a species classified as vulnerable.
If Woodside, Australia’s largest oil and gas company, were to gain approval to drill for gas at Scott Reef, the ecosystem would face a barrage of industrial impacts, including seismic blasting, gas flaring, underwater noise, artificial lighting, pipe- laying, and fast-moving vessels over years of construction and operation. Add to that the risk of a major oil spill that could be Australia’s worst environmental disaster, with consequences spreading far beyond Scott Reef.
A disaster worse than Montara, according to Woodside itself
Woodside has proposed drilling 50 new wells around Scott Reef to extract oil and gas from beneath the reef as part of the Browse project. Woodside has proposed to build a 900-kilometre-long undersea pipeline to connect the Scott Reef-Browse site with its North West Shelf facility at Karratha in Western Australia, where the gas would be processed, mostly for international export. Woodside has modelled a number of possible oil spill scenarios that could result from the Browse project. Woodside performed this modelling to comply with mandatory environmental impact assessment requirements under Federal and Western Australian laws.
To identify which areas are at risk of an oil spill from the Browse project, Woodside engaged experts to conduct probabilistic modelling. Experts simulated different spills, noting which locations would be contaminated by oil and how much oil would make it to shore. They also assessed how likely each location was to be affected.
” Woodside’s ‘worst case’ scenario is a blowout at the Torosa gasfield, directly under Scott Reef.”
Greenpeace Australia Pacific and Environs Kimberley’s analysis shows an oil spill at Torosa could see 893,739 barrels of condensate spilled into the Timor Sea. This would be up to 30 times bigger than the 2009 Montara oil spill, considered one of Australia’s worst environmental disasters. Oil leaked into the Timor Sea for days after an oil rig caught fire off the Western Australian coast, causing a 90,000 square kilometre oil slick that spread all the way to Indonesia.
People, places and wildlife at risk
Woodside’s modelling shows that an oil spill at Scott Reef could affect eight reefs, at least nine marine parks and three Indigenous Protected Areas. In the event of a worst-case oil spill, Scott Reef and Sandy Islet, being closest to the wellhead, would be worst affected.
Woodside’s modelling finds that the impacts to Scott Reef from a major spill like this ‘would likely be severe and potentially irreversible’. The impacts of an oil spill are not confined to Scott Reef – according to Woodside’s modelling, ‘hydrocarbon spills resulting from the proposed Browse to NWS Project have the potential to significantly impact shoreline habitats at Scott Reef, Ashmore Reef, Cartier Island and Rowley Shoals.’
Oil from a blowout could also reach neighbouring countries, including Pulau Rote, Savu, Sumba and West Timor in Indonesia, and Timor Leste. This is not an exhaustive list of all places that could be affected by an oil spill at Scott Reef. Once oil hits the water, its spread is influenced by the wind, tides, currents and other external conditions. An oil spill from the Browse project could have a less or more severe impact than the modelling indicates. Equally, Woodside cannot rule out other sites being affected.
A disaster for marine life
Woodside’s oil spill modelling shows that a blowout from the Browse project would put whales, turtles, seabirds, coral, significant feedstocks such as plankton and seagrass, fish, dolphins and other marine life at risk. According to Woodside, a Browse oil spill would:
- Directly threaten the coral at Scott Reef, with ‘potential for near total coral mortality in the worst affected areas’; a severe spill could also harm coral at Seringapatam Reef and the Rowley Shoals.
- ‘Significantly impact’ the plankton, seagrass and macroalgae that support the entire food chain.
- ‘Significantly impact bird species, including protected species’, which are ‘particularly vulnerable’ to oil spills.
A spill would not only threaten birds at Scott Reef, but those that nest or breed at Ashmore Reef and Cartier Island, Browse Island, islands along the Kimberley coastline (such as the Lacepede Islands) and Rowley Shoals. Woodside’s oil spill modelling specifically notes the potential risk to thirteen species of seabirds.
Oil spills also threaten whales and other cetaceans, especially concentrations of oil on the surface of the water. This can cause ‘sublethal and lethal effects’, especially when feeding, as whales and other marine mammals have been found to aspirate oil when breathing through an oil slick at the sea surface, thus absorbing hydrocarbons directly into their lungs, leading to sublethal and lethal impacts.
According to Woodside’s modelling, a Browse oil spill could be particularly harmful to the spinner dolphins living at Scott Reef with the potential for ‘a significant portion of this local population to be impacted in the event of a worst-case hydrocarbon spill’.
Marine reptiles, including the green sea turtles found at Scott Reef, are also at risk. Woodside’s modelling warns that an oil spill could cause ‘significant mortality amongst adults and hatchlings’, leading to ‘the potential for longer-term impacts on the Scott Reef – Browse Island genetic stock of green turtles’. Further, an oil spill could have lasting impacts on the breeding populations of olive ridley turtles, flatback turtles and hawksbill turtles. Essentially, all marine life found at or near the sea surface could be impacted by such a spill.
Woodside cannot be trusted
In Woodside’s inadequate response plan, Woodside states that it considers an oil spill to be ‘highly unlikely’ and the threat to the environment and wildlife to be ‘acceptable’. We do not believe these are credible assertions. For instance, the WA Environmental Protection Authority (EPA), which is assessing Woodside’s Browse to NWS proposal, did not agree. In August 2024, it emerged that the EPA advised Woodside that its Browse development posed ‘unacceptable’ risks to WA’s environment.
A potential oil spill from the Torosa field was one of the risks cited by the EPA in its preliminary decision not to approve the project. Woodside has subsequently revised its plans to drill for gas at Scott Reef, proposing to use unproven new technology that the company claims would bring a spill under control more quickly, reducing the spill time from 77 days to 13 days.
However, an independent assessment commissioned by Woodside did not support these claims. Instead, the expert questioned whether the piece of equipment proposed by Woodside — a capping stack — could be deployed in practice, and the time it would likely take to do so.
While Woodside has also claimed that a ‘pyrotechnic shear ram’ would reduce the spill time to as little as 24 hours, the company’s expert noted that this had yet to be ‘used in anger’ and that ‘there remains a risk’ that it fails to function.
Woodside’s alarming track record
Woodside’s stated ability to prevent or control a disaster is undercut by its poor environmental and safety track record. There have been numerous incidents at Woodside’s facilities over the last decade threatening the safety of its workers and the environment. These include:
- Whale calf collision: In August 2023, a tugboat operated by a Woodside contractor hit a whale calf in the Port of Dampier. The incident was only confirmed by the Department of Biodiversity, Conservation and Attractions (DBCA) after media inquiries.
- Explosion at Pluto LNG plant: In May 2023, an explosion forced Woodside to shut down and evacuate its Pluto LNG facility. Woodside was accused by unions of downplaying the incident. Eighteen months later, Woodside was again forced to put Pluto LNG into an emergency shutdown after the control systems failed.
- Oil spill near Ningaloo: In May 2025, Woodside spilled 16,000 litres of ‘hydrocarbons’ into the ocean near World Heritage listed Ningaloo Reef while decommissioning its Griffin facility. Three months later, the government regulator ordered Woodside to stop decommissioning operations at Griffin and nearby Stybarrow following a series of ‘preventable health and safety incidents’ at both sites.
- Oil spill in Cossack field: In 2016, a Woodside oil rig in the Cossack field leaked over 10,500 litres of oil into the ocean due to a degraded seal.
- Northern Endeavour clean-up debacle: Woodside evaded a $362 million decommissioning bill for its Northern Endeavour oil platform in the Timor Sea by offloading it onto a one-person operation. When the buyer went bankrupt, the Federal Government had to step in, eventually putting a levy on offshore oil and gas companies to recover the clean up costs.
- Cost-cutting and corrosion: In 2021, Woodside announced a 30% cut in operating costs, focusing on maintenance, despite repeated warnings from the government regulator about corrosion at its oil and gas facilities. The warnings continued. In July 2023, the regulator blamed Woodside’s ‘inadequate maintenance’ for serious corrosion of the flare bridge and support structure at its North Rankin complex.
- Abandoned infrastructure: Woodside finished extracting oil from the Enfield field in 2018. In 2019, the government regulator ordered Woodside to remove the Nganhurra Riser Turret Mooring (RTM), an 83-metre-long, 2,452 tonne piece of infrastructure. Woodside instead tried to sink the RTM near the World Heritage-listed Ningaloo Reef. After a public outcry, Woodside finally removed the RTM in October 2023.
