Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Iran war fallout continues
WORK FROM HOME: The International Energy Agency has advised its member countries to take 10 steps in response to the ongoing energy crisis fuelled by the Iran war, including reducing highway speeds and encouraging people to work from home, said the Guardian. It came after retaliatory attacks between Israel and Iran continued to destroy energy infrastructure in the Middle East, causing energy prices to soar further, said Reuters.
SUPPLY DISRUPTED: The IEA also said it is prepared to make more of its member nations’ 1.4bn-barrel oil reserves available to help ease the impacts of what it called the “biggest supply disruption in the history of the oil market”, reported Bloomberg. The outlet noted that Asian countries have been hit hardest by the shortages, caused by a “near-halt” of shipping through the Strait of Hormuz.
EU SUMMIT: The energy crisis dominated talks at an EU leaders summit on Thursday, said Politico. Arriving at the summit, Spain’s prime minister Pedro Sánchez attacked other European leaders for using the energy crisis as an excuse to “gut climate policies”, according to the EU Observer. The Financial Times said that some European leaders have asked the European Commission to overhaul its flagship emissions trading system (ETS) by summer in response to the energy crisis.
COAL BOOST: In response to the conflict, utility companies in Asia are “boosting coal-fired power generation to cut costs and safeguard energy supply”, said Reuters. UN climate change executive secretary Simon Stiell told Reuters: “If there was ever a moment to accelerate that energy transition, breaking dependencies which have shackled economies, this is the time.”
Around the world
- WINDFARM WINDFALL: The Trump administration in the US is considering a nearly $1bn settlement with TotalEnergies to cancel the French energy company’s two planned windfarms off the US east coast and have it instead invest in fossil-gas infrastructure in Texas, according to documents seen by the New York Times.
- BUSINESS CLASH: Following “clashes” with the agribusiness sector, Brazil launched its new climate plan, which calls for a 49-58% reduction in greenhouse gas emissions from 2022 levels by 2025 and includes “specific guidelines for different sectors”, reported Folha de Sao Paolo.
- SALES SLUMP: Sales of liquified petroleum gas from India’s state-run oil companies have fallen by 17% this month due to cuts in deliveries to commercial and industrial consumers “amid the widespread logistical bottlenecks triggered by the Iran war”, said the Economic Times.
- CUBAN ENERGY CRISIS: The US imposed an “effective oil blockade” on Cuba, leaving the country facing its “worst energy crisis in decades”, reported the Washington Post. Meanwhile, Chinese exports of solar panels to the island have “skyrocketed” since 2023, it added.
- RECORD HIGHS: An “unprecedented” heatwave in the western and south-western US is “shattering dozens of temperature records” and could lead to drought in California in the coming months, reported the Los Angeles Times.
- VULNERABILITY CONCERNS: Landslides that killed more than 100 people in southern Ethiopia have “renewed concerns about Ethiopia’s vulnerability to climate-related disasters”, said the Addis Standard.

Captured
Carbon Brief this week published a significant update to its map of how climate change is affecting extreme weather events around the world. The map now includes 232 new extreme weather events from studies published in 2024 and 2025. Of these events, 196 were made more severe or more likely to occur by human-driven climate change, 12 were made less severe or less likely to occur and 10 had no discernible human influence. (The remaining 14 studies were inconclusive.)
Spotlight
New Zealand breaks new ground on climate litigation
This week, Carbon Brief speaks to experts about a first-of-its-kind climate lawsuit in New Zealand.
Earlier this week, representatives from two environmentally focused legal advocacy groups challenged the New Zealand government’s climate-action plan in court.
The plaintiffs argued that the measures laid out in the plan are insufficient to achieve the country’s legal obligation to hold global warming to 1.5C above pre-industrial temperatures.
The case could be “influential” in shaping lawsuits and rulings around the world, one legal expert not involved in the case told Carbon Brief.
Reductions vs removals
The new case contends that there are several issues regarding the New Zealand government’s response to climate change.
One of the key arguments the plaintiffs make is that New Zealand’s second emissions reduction plan, which covers the period from 2026-30, is overreliant on the use of tree-planting to achieve its targets.
When the plan was released in December 2024, it was “immediately clear that it was a pretty lacklustre plan”, Eliza Prestidge Oldfield, senior legal researcher at the Environmental Law Initiative, one of the groups behind the legal case, told Carbon Brief.
The plan called for large-scale planting of pine tree plantations, which are not native to New Zealand and have a high risk of burning. Because of this, there are concerns about how permanent any carbon removal provided by these plantations actually can be, experts told Carbon Brief.
Catherine Higham, senior policy fellow at the Grantham Research Institute on Climate Change and the Environment who was not involved in the case, said:
“The lawyers are arguing that there are real challenges with equating the emissions that you may be able to remove from the atmosphere through afforestation with actual emissions reductions, which are much more certain.”
‘Global dialogue’
While other climate lawsuits elsewhere in the world have also focused on the inadequacy of a government’s plan to meet its stated emissions-reduction targets, this is the first such case that addresses the role of removals head-on.
Lucy Maxwell, co-director of the Climate Litigation Network, told Carbon Brief that the lawsuit “builds on a decade of climate litigation” in national, regional and international courts.
Maxwell, who was not involved in the New Zealand case, added that there is a “real global dialogue” between, not just plaintiffs, but national courts as well. She said:
“[National courts] look to common issues that have been decided in other countries. They’re not binding on that court if it’s at the national level, but they are influential.”
Given that many other countries have legal frameworks requiring their governments to create plans outlining the pathway to their long-term climate targets, Prestidge Oldfield told Carbon Brief that other jurisdictions “should be interested in these questions around the level of certainty”.
Higham noted that, even if the case is successful, addressing the plan’s shortfalls will face its own set of challenges. She told Carbon Brief:
“A lot of these decisions are political and they can be politically contentious…Those [measures] have to be put into action through legislation and that is then subject to the usual political process. So that’s where the challenge comes in.”
While she could not speculate on the outcome of the case, Prestidge Oldfield said it was “very heartening” to see that both the judge and the opposing counsel “appreciated how much of a concern climate change is globally”.
She added:
“It’s not a given that the judge would even be interested in climate change.”

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.

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.

European, island states seek clear future for global roadmap to cut fossil fuels
Some European, small island and other nations argue the forthcoming roadmap should be part of UN climate talks, while Russia has resisted this idea
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.

In a packed room last Friday, the COP30 Presidency presented preliminary elements of the work on the global roadmap for the transition away from fossil fuels and some European and small island governments argued the roadmap should be integrated into the formal negotiation process. But besides the global work, how is Brazil’s national roadmap coming along?
“The presidential order [by Lula at COP30] was that the ministries of environment, finance and energy should work together,” Flávia Bellaguarda, extraordinary advisor to Brazil’s environment ministry, told Climate Home News in Bonn.
“We do have different points of view about what the roadmap means. We have to face our contradictions and bring them to the table because the roadmap is about energy security, economic security, social security,” she said, adding that “we have reached a common place of the guidelines of what must be addressed on the roadmap”.
Those guidelines—that Bellaguarda couldn’t share yet—are now under revision by the Brazilian presidency and then will be analysed by the National Energy Policy Council (CNPE). After those revisions, the three ministries will begin working on the roadmap itself and its governance. That work will include consultations with different stakeholders, including representatives of the energy sector and civil society organisations.
The Brazilian government still prefers not to give dates for these next steps because “they do not expect it to be something quick,” but rather to respect the steps and time that the process requires.
Roadmaps to transition away from fossil fuels are, at least for now, voluntary for each country. “There is no right and wrong on how to do the roadmap. Countries know what is best for each reality,” said Bellaguarda, encouraging countries to advance on their national roadmaps alongside the global one. “It’s not easy to address the issue nationally, but it’s totally necessary.”
