DeBriefed 20 March 2026: Energy crisis deepens | Brazil’s new climate plan | New Zealand climate case Giuliana Viglione 03.20.26Giuliana Viglione 20.03.2026 | 2:15pmWelcome 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. 1% The percentage of England’s land surface that could be devoted to renewables by 2050, according to the long-awaited “land-use framework” released by the UK government this week and covered by Carbon Brief.

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.” Watch, read, listen COMMON APPROACH: The Heated podcast analysed fossil-fuel advertisements and highlighted the most common deception tactics they employed.
