Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Intensifying hurricanes
STILL POWERFUL: Hurricane Milton made landfall in Florida on Wednesday “weakening but still tremendously powerful”, the Guardian reported, bringing “catastrophic winds likely to cause significant property damage” and leaving “nearly 3m homes and businesses…without power”. At least 16 people were killed across the state, officials told CBS News. Bloomberg noted that the US “has been hit by five hurricanes so far this year”.
2.5 TIMES MORE FREQUENT: Record-breaking sea temperatures across the Gulf of Mexico are a key driver of the intense hurricanes devastating the region this year, Carbon Brief reported (see more below). The Independent covered new World Weather Attribution analysis finding that hurricanes as intense as Hurricane Helene, the second most deadly US storm in history which made landfall just days before Milton, “are now about 2.5 times more frequent” because of human-caused climate change.
GLOBAL CRISIS: Elsewhere, “unprecedented” flooding in Niger killed 339 people and displaced more than 1.1 million, Radio France Internationale said, adding that “neighbouring Mali [saw] over 40 people killed and thousands displaced”. Floods and landslides in Bosnia killed at least 22 people, Le Monde reported. Finally, in Bangladesh, five people died and more than 100,000 were stranded by floods, Reuters said.
Oil rush
AMBITION ABANDONED: BP will abandon its “ambitious target” to cut oil and gas production by 40% by 2030, the Times reported, with the move expected to be formalised in February. The newspaper added that BP is “battl[ing] to close a valuation gap” with industry rivals and faces pressure from investors to increase fossil fuel production and “stop investing in any more ill-conceived wind projects”. (Any new fossil fuel projects globally are incompatible with keeping global warming at 1.5C.)
RACE TO THE BOTTOM: India will “radically reform regulations and invite foreign oil majors to explore both onshore and offshore [opportunities]” as the country “races to extract as much oil as possible while there remains a market”, according to the Financial Times. The newspaper noted that oil companies hope India’s strong economic growth forecast “will underpin future demand”.
UNLIKELY CHAMPIONS: In the US, oil companies are lobbying Republican presidential candidate Donald Trump “not to slash provisions of the Inflation Reduction Act”, the Wall Street Journal said, as many of them benefit from the law’s provision of billions of dollars in “tax credits vital for their investments in renewable fuel, carbon capture and hydrogen”.
Around the world
- NO-SHOWS: Ahead of COP29, the EU has called for a phaseout of “inefficient fossil fuel subsidies that do not address energy poverty or just transitions”, ENDS Europe reported. Meanwhile, Bank of America, BlackRock, Standard Chartered, Deutsche Bank and other financial institutions will “skip” COP29, the Financial Times said.
- STREAMLINING: COP16 host Colombia is pushing for the United Nations to combine the COPs for climate change, biodiversity and desertification in order to avoid “wasting time” and create “synergies” in countries’ climate plans, according to Reuters.
- NEW RULES: The UN has developed a compulsory mechanism that aims to prevent carbon credit project developers from breaching human rights or causing environmental damage with their activities, Climate Home News reported.
- ‘CATASTROPHIC’ DECLINE: Wildlife populations have dropped by a “catastrophic” average rate of 73% over the past 50 years, according to a World Wild Fund for Nature (WWF) report covered by the Washington Post.
- TWO EXTREMES: The World Meteorological Organization found that 2023 was the “driest year in more than three decades for the world’s rivers”, the Associated Press said. At the same time, the Financial Times reported, rising temperatures “helped drive extreme rainfall events” in September.
5,500
The amount of new renewable energy capacity, in gigawatts, to be added globally between 2024 and 2030, 2.6 times greater than total additions between 2017 and 2023, according to a new report by the International Energy Agency.
Latest climate research
- The presence of permafrost almost halves riverbank erosion rates in an Arctic river, according to a study published in Nature.
- Research in Nature Climate Change found that, even if global warming is limited to 1.5C, climate change’s impact will increase inequality by an average of 1.4 points of the Gini index, the most common measure of income disparity, by the end of the century.
- A new study in Nature Climate Change estimated that climate change will increase the risk of whale sharks, the world’s largest fish, crossing into global shipping routes and colliding with vessels.

Captured

The amount of heat stored in the waters of the Gulf of Mexico has reached record levels this month amid an unprecedented marine heatwave. These temperatures, themselves made 200-500 times more likely by climate change, played a key role in causing the hurricanes devastating the US this year to be more intense, according to a new study covered by Carbon Brief. The hurricanes Helene and Milton, which struck the US within two weeks of each other, were made more powerful by passing over the gulf, due to the hotter ocean water passing more energy to the storms and making them intensify more quickly.
Spotlight
How Scotland is protecting its ancient stone circles from climate change
This week, Carbon Brief explores what climate change means for a 5,000-year-old monument in Orkney.
Orkney, in the north of Scotland, is famous for its neolithic monuments, including the Ring of Brodgar, the largest stone circle in Scotland.
Historic Environment Scotland (HES), a public body that maintains Scotland’s historic sites, encourages tourists to help monitor the monument for signs of the impact of climate change through the citizen science programme Monument Monitor.
Carbon Brief interviews Dr Mairi Davies, climate change policy manager at HES, about the impact of climate change on the site and the effectiveness of citizen science in combating it.
Carbon Brief: What impact has climate change had on the Ring of Brodgar?
Mairi Davies: In 2019, we hosted a workshop in Orkney to apply the Climate Vulnerability Index (CVI), a methodology developed to rapidly assess climate impacts for all types of world heritage properties, to the Heart of Neolithic Orkney World Heritage site (HONO), which includes the Ring of Brodgar.
HONO was determined to be extremely vulnerable to the impacts of three key climate drivers: sea level change; precipitation change; and storm intensity and frequency change.
Increased footfall at the Ring of Brodgar is interacting with changes in precipitation patterns – primarily increased precipitation, but also periods of very dry weather – which has led to serious and increasing footfall erosion, threatening the fabric of the site.
CB: What inspired HES to turn to citizen science to monitor these impacts? And has it been effective?
MD: We care for a diverse estate of properties, many of which are in remote areas. While we undertake regular site inspection visits, we can’t be everywhere at once.
Since launching in 2018, Monument Monitor has been a really useful tool for aiding conservation work across the sites we care for, as well as fostering engagement with visitors and local communities alike. Using pictures sent to us by visitors, we’ve been able to model how climate change is affecting flooding at Machrie Moor Standing Stone Circle in Arran, as well as measuring the impact of increased visitor footfall at Clava Cairns…At the Ring of Brodgar, visitor photos are helping us record how well the site can drain after increasing incidences of extreme weather.

CB: What more needs to be done to protect Scotland’s neolithic heritage from climate impacts?
MD: Over the last few years at the Ring of Brodgar, we have undertaken an extensive programme…to create more resilient footpaths for visitors. Balancing access at the Ring of Brodgar, especially to the inner ring, with conservation is now a key issue for site management, with periods of partial site closure required to allow areas of footpath to recover.
Projects such as SCAPE (Scotland’s Coastal Archaeology and the Problem of Erosion) work with the public to research and promote the eroding archaeological remains on Scotland’s coasts.
More broadly, HES will continue its work with communities and partners across Scotland to investigate the impacts of climate change on our historic sites and to support climate adaptation. Our Guide to Climate Impacts identifies many of the risks and hazards of climate change that are facing Scotland’s historic environment and offers owners, local communities and carers of historic sites routes to…enhance resilience to climate change.

Trump Administration Abandons Fight Against Wind Energy as Clean Energy Output Surges
The clean energy sector is showing resilience despite challenges thrown at it by a hostile White House, a recent report found. A string of legal victories has further dampened the Trump administration’s efforts to halt wind and solar power.
The Trump administration has abandoned its effort to halt wind energy projects across the United States and dropped its challenge to the court ruling that tossed President Donald Trump’s order freezing federal permitting and leasing for wind projects. States that challenged the order hailed the development as one of the most significant legal victories against the Trump White House’s campaign against the energy transition.

Analysis: UK’s EV drivers are now saving £1,100 each a year – and £3bn in total
Amid reports that the government could weaken the UK’s electric vehicle (EV) targets, Carbon Brief analysis reveals the nation’s EV drivers are saving more than £1,100 a year in fuel costs, compared with running a petrol car.
Battery EVs (BEVs) are roughly four times more efficient than combustion-engine cars, making them far cheaper to run – particularly since the Iran crisis caused a spike in fossil-fuel prices.
The savings from driving BEVs are also more than three times higher than for “plug-in” hybrids (PHEVs), which evidence shows are mostly driven with their combustion engines.
In total, the more than 2m BEVs, 1m PHEVs and 100,000 electric vans on UK roads are saving drivers around £3bn a year, Carbon Brief’s analysis shows, as illustrated in the figure below.
In addition, these EVs are avoiding the need for nearly 2.5bn litres of fuel and cutting carbon dioxide (CO2) emissions by nearly 7m tonnes each year.
Despite recent news that EVs are now cheaper to buy than petrol cars, as well as having far lower running costs, BBC News says the government is “set to water down” its EV sales targets.
The broadcaster explains that the current goal, under the UK’s “zero-emissions vehicle” (ZEV) mandate, is for 80% of new car sales to be BEVs by 2030.
It says that the government is set to consult on weakening this to between 50% and 70%, following “lobbying” by carmakers and trade unions.
According to the Sunday Times, prime minister Keir Starmer “is understood to have overruled the energy secretary [Ed Miliband] after sustained pressure from industry, the Unite union and Peter Kyle, the business secretary”.
The car industry has consistently claimed there is insufficient demand for BEVs to meet the targets under the ZEV mandate, yet the government says manufacturers have “over-complied” to date. Independent analysts say the industry is on track to continue beating the ZEV mandate goals.
The industry has been able to beat its targets by using a wide range of “flexibilities”, which were introduced after a previous round of lobbying. These allow carmarkers to meet part of their EV targets by selling more efficient combustion cars, such as hybrids and plug-in hybrids.
The ZEV mandate is the single-largest part of the government’s plans to meet its legally binding climate goals over the next decade.
The advisory Climate Change Committee (CCC) previously warned that the extra flexibilities would result in a larger number of hybrids being sold, at the expense of battery EVs.
When it consulted on the ZEV mandate in 2023, the then-Conservative government noted that PHEVs do not deliver the cost and CO2 savings they are advertised with.
It pointed to “dramatic” differences between the performance of PHEVs in test cycles and what they deliver under real-world conditions.
In practice, less than a third of miles driven in PHEVs are fuelled by electricity, with petrol making up the rest. As a result, cost and CO2 savings from BEVs are three times larger than for PHEVs.

UN’s first Paris Agreement carbon credits face human rights and climate concerns
Civil society groups have called for an investigation into the first carbon credits approved under a new UN mechanism, alleging the project is linked to Myanmar’s military junta – which the UN says is guilty of human rights abuses – and has “massively” overstated its climate impact.
The programme, which aims to cut emissions by distributing efficient cookstoves across Myanmar, received approval to issue around 650,000 carbon credits from the Article 6.4 Supervisory Body in February, in a landmark moment for the Paris Agreement’s carbon market. Only two projects have been given the green light by the mechanism’s regulator so far.
But two reports published last week, led by the Global Forest Coalition and Brussels-based NGO Carbon Market Watch, raised serious concerns about the project’s implementation in conflict zones where civilians have faced airstrikes and mass displacement as well as its emission-reduction calculations.
Project continued after military coup
Myanmar has been ravaged by a brutal civil war since the country’s military overthrew the democratically elected government in a coup d’état in February 2021. The military regime has attacked civilian populations, persecuted ethnic minorities and committed widespread sexual violence, among other serious human rights violations, the UN Special Rapporteur on the situation of human rights in Myanmar said in April.
The cookstove programme started in 2018 under the previous UN-run carbon offsetting scheme – the Clean Development Mechanism (CDM) – as a partnership between Myanmar’s Ministry of Natural Resources and Environmental Conservation (MONREC) and the Climate Change Center (CCC), a South Korean NGO, with investment from private South Korean firms.
The project continued operating after the coup. For most of the period between 2021 and 2022 in which the issued credits were generated, MONREC was led by Colonel Khin Maung Yi, who was sanctioned by the European Union in 2021 for supporting the military regime, the Global Forest Coalition report said.
CCC acknowledged engaging with government authorities after the coup but said this “should not be interpreted as political endorsement” of the junta. The South Korean NGO added that abandoning the programme when political circumstances changed “would not necessarily have been the most responsible outcome for the households involved”.
Conflict prevents on the ground verification
The Global Forest Coalition report raised particular concerns about the project’s implementation in Myanmar’s central Dry Zone, including Sagaing Region, an anti-junta resistance stronghold that has been most heavily affected by the conflict and routinely targeted by airstrikes and violent attacks. The region accounts for more than a third of Myanmar’s 3.8 million internally displaced people.
The NGOs said that, in addition to ethical concerns about carbon credits being produced by the military government in an area actively affected by its attacks, this raises questions over the ability to effectively verify the climate integrity of the projects.


Before carbon credits are issued, external auditors need to validate the claims made by project developers and confirm that the emission reductions claimed are correct. This process usually includes site visits to a representative sample of households to check how the improved cookstoves are being used.
But, because of the “volatile political situation” in Myanmar, the auditing team was not able to leave the capital Yangon and could only speak to project participants remotely via Zoom, project documents show.
“Due to ongoing armed conflict on the ground, the data currently used to justify carbon credit issuance in Sagaing by the Burmese military junta is unverifiable and highly likely fraudulent,” said Zaw Tuseng, founder and president of the Myanmar Policy Institute, which contributed to the report, in a written statement. “This demands an immediate suspension of credit transfers until a neutral, conflict-sensitive audit can be conducted.”
“Exceptional circumstances”
CCC told Climate Home News that, although it recognises that on-site verification is “generally preferable, particularly in complex operating environments”, the decision to opt for remote controls was not taken “as a discretionary shortcut, but as an approved alternative under exceptional circumstances”.
The South Korean NGO added that it reviewed the feasibility of the project at community level “on an ongoing basis” and it “did not identify conflict-related incidents that directly affected project implementation activities in participating communities during the monitoring period”.
A spokesperson for the UN climate change body told Climate Home News that, when site access is not possible, the UN carbon credit mechanism allows for “alternative verification approaches while still maintaining conservative assumptions and environmental integrity safeguards”. “These provisions ensure that crediting can only proceed where evidence is reliable,” they added.
Contested methodology
Carbon markets are seen as an important channel to raise money to help low-income communities in developing countries switch to less polluting cooking methods, both reducing CO2 emissions and improving air quality. But several cookstove offsetting projects have faced criticism from researchers and campaigners who argue that climate benefits are often exaggerated and weak monitoring can undermine claims of real emission reductions.
The project in Myanmar uses a contested methodology developed under the earlier Kyoto Protocol that was rejected last year by The Integrity Council for the Voluntary Carbon Market (ICVCM), a watchdog that issues quality labels to carbon credit types, because it found it “insufficiently rigorous”.
EU carbon credits could supercharge world’s clean cooking push, France says
After transitioning from the CDM to the new mechanism, the project was required to apply “more conservative” assumptions to calculate emission reductions, which resulted in 40% fewer credits being issued, according to the UN climate change body.
“The result is consistent with environmental integrity requirements and ensures that each credited tonne genuinely represents a tonne reduced and contributes to the goals of the Paris Agreement,” Mkhuthazi Steleki, the South African chair of the Article 6.4 Supervisory Body, which oversees the mechanism, said in February.
Too many credits issued
But Carbon Market Watch claimed in a second report last week that, despite the adjustment, the project is still likely to issue seven times more credits than its real climate impact justifies, comparing its calculations with values from peer-reviewed scientific literature.
The biggest driver of the credit inflation, the group said, is the failure to account for “stacking” – the widespread practice of households using multiple stoves at the same time, including more polluting ones the project does not monitor.
Peer-reviewed science considers a stacking rate of 68% a conservative assumption, but the methodology used by the Myanmar programme makes no allowance for it at all, the report said.
CCC disputed those findings. In a written response to Climate Home News, it said the project was developed under methodologies approved within the UN climate framework and that external recalculations by researchers are not “determinative of the level of crediting achieved”.
The credits are expected to be used primarily by major South Korean polluters to meet obligations under the country’s emissions trading system – a move that will also enable the government to count those units toward emissions reduction targets in its nationally determined contribution (NDC), the UN climate body told Climate Home News.
Myanmar will use the remaining credits to achieve in part the goals of its own national climate plan under the Paris Agreement.
“Over-crediting, at any magnitude, cannot be compatible with the climate ambition of a world striving to limit global warming to 1.5ºC,” said Isa Mulder, an expert at Carbon Market Watch.
