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.)

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.”

The post DeBriefed 20 March 2026: Energy crisis deepens | Brazil’s new climate plan | New Zealand climate case appeared first on Carbon Brief.
An Lambrechts is a biodiversity politics expert at Greenpeace International with extensive experience in biodiversity-related multilateral negotiations. She is the head of the Greenpeace delegation at the Convention on Biological Diversity (CBD) COP17 happening in Yerevan, Armenia.
In 2022, COP15 delivered the landmark Kunming-Montreal Global Biodiversity Framework to halt and reverse biodiversity loss by 2030. With COP17 starting in Yerevan, we are now halfway to the deadline, and according to the first Global Review of progress, countries are not on track to meet the biodiversity targets, and implementation must accelerate fast.
One of the main findings of the Global Review is that funding falls far short of the scale needed to halt and reverse nature loss. But the crisis facing the world’s biodiversity is not an absolute scarcity of capital – it is a profound public policy distortion.
The global economy currently spends roughly $30 destroying nature for every single dollar invested in its protection. According to a report from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, a staggering $2.4 trillion is spent in public subsidies for fossil fuels, agriculture and water use, while global investment in biodiversity conservation and restoration stands at a mere $220 billion.
Countries urged to ramp up “insufficient” nature policies at COP17
Yet, discussions about how to close the biodiversity finance gap continue to claim that salvation lies in mobilising private capital, scaling offsets and “derisking” investments in nature. This is a fundamental misunderstanding of both the nature of ecological stewardship and of the global financial architecture.
Biodiversity conservation is not a speculative investment portfolio – it is the foundation of human survival. The health of our planet is a non-monetisable, non-excludable public good. Expecting profit-seeking private capital to protect nature perpetuates the structural drivers of ecosystem destruction in the first place.
But if private market mechanisms cannot save biodiversity, where will the necessary public resources come from?
Money going to the wrong places
The answer lies in recovering the vast public wealth currently drained by cross-border tax abuse, financial secrecy and corporate impunity. Finance and environment ministers meeting in Yerevan must give a strong political signal that, to avert ecological breakdown, countries need to take swift action to reform global tax rules, eliminate harmful public subsidies and cancel unsustainable sovereign debts for the public revenues to end up where they belong.
Extractive sectors such as industrial agriculture, fishing, timber and mining continue business-as-usual, often heavily subsidised by public treasuries, while voluntary carbon and biodiversity offset markets pose a serious risk to nature conservation. Offset schemes have delivered only a negligible fraction of the funding needed to preserve ecosystems, allowing industries to continue with their destructive business-as-usual practices.

Global deforestation slowed in 2025 but Brazil’s election could undo “fragile” gains

Brazil confident new rainforest fund will reach $10bn donor milestone
Brazil’s environment minister said the Tropical Forest Forever Facility has raised billions in record time – which he hopes will convince more investors
In advanced economies, public funding often actively undermines biodiversity. In Europe, over €5.3 billion in public subsidies is funnelled annually into intensive forest biomass harvesting under renewable energy directives, degrading primary forest ecosystems and undermining long-term climate resilience. Pleading with private investors to fill a “finance gap” while pouring billions into ecological destruction is an exercise in futility.
Developing countries struggle with debt burden
For developing countries, reliance on private finance is further compounded by a crushing sovereign debt crisis. In 2024, public debt in developing economies reached record levels, with net interest payments alone absorbing $921 billion. A record 61 developing countries now spend more than 10% of government revenue on foreign debt service, with many climate-vulnerable nations spending twice as much servicing external debt as they receive in climate and biodiversity finance combined.
This burden acts as a structural driver of ecosystem destruction. Under pressure from external creditors and international financial institutions to avoid default and secure foreign exchange, governments are routinely forced into austerity measures and pushed to expand raw commodity exports into pristine biomes.
Comment: World Bank and IMF should lead the financial system in responding to the climate crisis
The current negotiations for a United Nations Framework Convention on International Tax Cooperation (UNFCITC) also offer a way forward. An estimated $492 billion in tax revenue is lost every year to offshore tax havens. Multinational corporations account for around $348 billion of this total by shifting profits away from the countries where real economic extraction and environmental degradation occur.
In the mining sector alone, developing nations lose tens of billions annually to corporate tax dodging. Furthermore, international financial secrecy shields environmental criminals, with illicit financial flows from illegal logging draining between $51 billion and $152 billion annually.
At COP17, leaders must seize the opportunity to build a bridge between the two conventions and enhance cooperation. Governments must put the world on a firm path to securing predictable, sufficient, sovereign public finance for biodiversity conservation. It’s the only path to a restorative, rights-based future for people and the planet.

Greenpeace delivers 47 metre-long petition with half a million signatures to Woodside HQ following major gas protest
Greenpeace delivers 47 metre-long petition with half a million signatures to Woodside HQ following major gas protest
PERTH, Monday 19 October 2026 — Dozens of Perth community members delivered a giant petition, signed by almost half a million people, to Woodside’s corporate headquarters this morning, calling on the government to save Scott Reef from Woodside’s reckless Browse gas proposal.
Dressed in sea creature costumes and hats, supporters carried one of Australia’s biggest environmental petitions to Woodside’s headquarters, and a local choir performed a ‘Scott Reef’ rendition of Angie McMahon’s iconic cover of ‘Reckless’ by Australian Crawl.
On the sidelines of the Perth Global Citizen Now event, it comes following a two day-long protest at Woodside’s Scarborough gas platform that saw activists scale and occupy the Floating Production Unit calling to “Stop Woodside’s Dirty Gas” and “Save Scott Reef”. The activists were taken from the platform by police helicopter on Sunday afternoon.
David Ritter, CEO at Greenpeace Australia Pacific, said: “Less than a day after two Greenpeace Australia Pacific activists were arrested for their peaceful protest at Woodside’s Scarborough gas platform to save Scott Reef, we are here again with another message to Woodside: half a million of us do not want your dirty gas at Scott Reef.
“Community pressure on Woodside is rising. Today we are here to show Woodside that they can’t ignore half a million people who want Scott Reef protected, not turned into an industrialised gas zone.
“Woodside can’t be trusted with our oceans. Woodside’s plans to drill up to 57 toxic wells at Scott Reef, Australia’s largest oceanic reef, putting endangered pygmy blue whales at risk, and jeopardising a nesting ground for unique green sea turtles.
“We Australians love our oceans and this is an opportunity for our governments to do the right thing, to reject Woodside’s reckless drilling plans, and save Scott Reef.”

Greenpeace Australia Pacific activists in police custody after two-day protest against Woodside’s Browse gas project at Scott Reef
PERTH, Sunday 18 October 2026 — Two Greenpeace Australia Pacific activists are in police custody after occupying a gas platform at Woodside’s Scarborough gas project, in peaceful protest of the fossil fuel corporation’s plans to drill for oil and gas at Scott Reef.
NEW footage and photos of the peaceful protest available here and on Instagram
The activists used specialised climbing equipment to scale and attach themselves to a Floating Production Unit (FPU), a key piece of gas processing infrastructure at the Scarborough gas field over 200km off the coast of Exmouth, at around 05:45am AWST on Saturday and proceeded to occupy the platform for two days, displaying banners reading “Stop Woodside’s Dirty Gas. Save Scott Reef.”
Special police forces landed a helicopter on the FPU at around 11:30am AWST. The activists safely removed themselves from their equipment before being taken into police custody around 1:00pm AWST. At the time of writing, no charges have been laid.
David Ritter, CEO at Greenpeace Australia Pacific, said: “It takes guts and conviction to do what our activists have done, peacefully protesting Woodside’s reckless gas plans at Scott Reef.
“Woodside’s plans to drill up to 57 toxic wells at Scott Reef are outrageous. If allowed to go ahead Woodside would turn Scott Reef, Australia’s largest oceanic reef, home to nesting green sea turtles and elusive pygmy blue whales, into an industrial gas zone. Around half a million people have called on our governments to stop Woodside and to save Scott Reef.
“Our activists are highly trained and experienced in these activities. West Australia has a proud history of peaceful, democratic protest at sea, to protect our oceans from environmental threats. From whaling in Albany in the seventies, to Woodside’s threat to Scott Reef today, there’s more than fift
