Key developments
Amazon summit leaves observers ‘frustrated’
MISSING THE TARGET: The fifth summit of the Amazon Cooperation Treaty Organization (ACTO) took place last Friday, with the release of the Bogotá Declaration coming the next day, Agência Brasil reported. The meeting was a “platform to update the commitments of the countries” that share the Amazon rainforest, the outlet said. The declaration “emphasised the urgency of coordinated action against deforestation and biodiversity loss”, but there was an “absence of clearer targets”, which “frustrated” observers and civil-society groups. Agência Brasil also said that the “issue of energy transition and fossil-fuel exploration” was divisive at the summit.

INDIGENOUS INCLUSION: Ahead of the meeting, Indigenous groups were “demanding that oil be left underground…[and] that the Amazon be declared the world’s first no-go zone for fossil-fuel exploration and exploitation”, EFE Verde reported. According to Stand.earth, the summit “strengthen[ed] Indigenous participation” despite “fail[ing]” to meet the fossil-fuel demands. The summit resulted in the creation of the Amazonian Indigenous Peoples Mechanism (MAPI), which Stand.earth explained “establishes a co-governance structure” for ACTO where each country is represented by both a government and an Indigenous delegate.
FUND THE FACILITY: Another element of the Bogotá Declaration was a pledge to support the Tropical Forests Forever Facility (TFFF), Climate Home News reported. The outlet added that the declaration “invites” countries to “announce substantial contributions” in order to “guarantee the fund’s quick activation”. Brazil’s president, Luiz Inácio Lula da Silva, said: “We’re fed up with promises…I want to see who’s going to put up the money to keep the forest standing.” Meanwhile, ((o))eco reported that Brazil saw an 84% increase in international climate finance from 2019-20 to 2021-22, but forests received just 2%.
Wildfires continue to burn
NEW EU RECORD: Wildfires have ravaged more than 1m hectares in the EU in 2025, the largest area since records began in 2006, according to an analysis by Agence France-Presse. The news agency analysed data from the European Forest Fire Information System and found that Spain, Cyprus, Germany and Slovakia have been the hardest hit over the past two decades. Additionally, satellites revealed that wildfires across the Iberian peninsula released 13m tonnes of carbon dioxide this year – six times larger than 2022 levels, El Periódico reported.
HARDEST HIT: Six firefighters died while combatting “devastating wildfires exacerbated by an enduring heatwave” in Spain and Portugal, according to France24. More than 343,000 hectares were “ravage[d]” this year in Spain, setting a new national record, the outlet said. Scientists identified the primary cause of the fires in both countries as an “overabundance of flammable vegetation on abandoned land and authorities’ failure to take preventive measures,” which prompted Spain’s environmental prosecutor to initiate an “investigation into the lack of prevention plans”, Politico added.
US FIRES: Wildfires in California and Oregon led to the evacuation of thousands of homes, the Associated Press reported. In Oregon, the fire began Thursday and “grew quickly amid hot, gusty conditions”, the newswire said. A “sweltering” heatwave has hospitalised people in the western US, it added. Mongabay covered the “scientific standoff” surrounding the “active management” of forests, which consists of using controlled burning and thinning of forests to promote regeneration and resilience. It added that forest managers are “grappl[ing] with the growing effects of climate change”.
News and views
PRIVATE SECTOR CALL: Nature loss will reduce UK GDP by 5% without a “greater effort” from the private sector to halt the decline, the Guardian said. A report from the Green Finance Institute and WWF said that companies in many sectors can receive economic returns from investment in nature. The outlet noted that some businesses “are failing to reform or are unaware of the impact of their actions on nature and the climate”. The report listed suggestions for companies to take action on nature decline.
SOLAR SLOWDOWN: The US Department of Agriculture (USDA) announced it will “heighten scrutiny of some solar and wind projects” on farmland across the country, reported Reuters. The agency said it will stop funding larger renewable energy facilities and will not allow the use of foreign-made solar panels. Inside Climate News said the agency had expressed concern about the possible expansion of wind and solar facilities on productive farmland. However, the outlet cited a 2024 USDA analysis finding that renewables occupy 0.05% of the 897m acres of pasture and cropland in the country.
FISHERY REFORM: Ghanaian president John Dramani Mahama signed a “sweeping” fisheries and aquaculture reform act into law last week that the government believes will “ensure sustainability…and better protection for the country’s fishing communities”, according to Ghana Broadcasting Corporation. One provision in the bill is an expansion of the country’s inshore exclusion zone, which prevents industrial trawling ships from encroaching on artisanal fishing grounds. News Ghana reported that the law is “designed to address EU trade sanctions”, which threaten the country’s $425m annual seafood exports.
POLARISED POLICY: A new forest land policy in the Philippines has been touted by officials as a “major shift in forest governance”, but has been questioned by civil society organisations, Mongabay reported. Under the policy, farmers are able to carry out multiple different land uses – including reforestation, ecotourism, conservation and commercial use – in designated forest areas. The secretary of the Philippines’s environment department said the reform is an attempt to “unlock the economic potential” of the country’s forests and scale up sustainable investment. The outlet said that environmental groups warned of the policy resulting in forest degradation, the displacement of Indigenous peoples and greenwashing.
PARAGUAYAN PLANTATIONS: Apple purchased carbon credits associated with the use of agrochemicals harmful to communities on eucalyptus plantations in Paraguay, a joint investigation for Consenso and Climate Tracker revealed. The investigation used documents, field visits and satellite images to show that the forestry company selling these carbon credits does not “comply with agrochemical regulations”. It added that eucalyptus monocultures cover more than 300,000 hectares in Paraguay. Residents have pointed out the risks of wildfire due to “persistent drought” conditions in the country over the past five years. Apple had not responded to the allegations at the time of the investigation’s publication.

Extreme heat could triple lost work hours by century’s end
This week, Carbon Brief covers a new UN-backed report that examines the impacts of climate change on labour productivity and health.
Manual labourers, such as farmworkers and fisherfolk, are “already” being impacted by rising temperatures, according to two UN agencies.
A new report from the World Meteorological Organization (WMO) and the World Health Organization (WHO) examined the effects of climate change on heat stress in the workplace and offered technical guidance for employers, workers and policymakers.
The report called occupational heat stress a “global societal challenge”.
It also noted that both the direct and indirect impacts of environmental heat stress will worsen and spread geographically as the world continues to warm.
In a press conference prior to the release of the report, Dr Rüdiger Krech, interim director of the WHO’s environment, climate change and migration programme, said the report offered the “most comprehensive evidence yet on how rising temperatures are harming workers”.
‘Adverse consequences’
In 1969, the WHO published a technical report on the potential health threats of working under environmental heat stress. The report concluded that “knowledge relating to occupational heat exposures is inadequate in many respects”. It recommended several priorities for further research.
The new report updated the 1969 report with decades’ worth of research showing that workplace heat stress “directly threatens workers’ ability to live healthy and productive lives and leads subsequently to worsening poverty and socioeconomic inequality”.
It found that around half of the global population currently experiences “adverse consequences of high environmental temperatures”. Agricultural work is “often regarded as [one of] the highest-risk occupations” for work-related heat illness, it said.
Farmworkers typically work with little or no shade during the hottest hours of the day. Some groups of agricultural workers – such as those who manually spray pesticides or other agrochemicals – face added risk of heat stress due to the protective gear that they must wear.
The report warned that, while several early warning systems are in place to protect people during heatwaves, these systems may not be adequate to protect workers, who differ in their exposure to heat and their ability to adapt.
Raising the risk
The new report also examined the changing risks of occupational heat exposure in the context of climate change.
Citing the work of the Intergovernmental Panel on Climate Change, it noted that each additional 0.5C of warming “significantly raises the risk of longer and more severe heatwaves”. The largest relative shifts will take place in the temperate mid-latitudes, but the frequency of dangerous events will also increase in the tropics, which have the “greatest workplace heat stress problems at present”.
Under the emissions scenario that aligns with current national climate policies, the worst-affected countries will face annual work hour losses of up to 11% by the end of the century – up from 2-4% today, the report said.
Previous research has found that 3C of warming could reduce global labour capacity by up to 50%, driving up food prices and requiring higher levels of agricultural employment to make up the shortfall.
Krech told the press conference:
“Protecting workers from extreme heat is not only a health priority, it is essential to building resilient, equal and sustainable societies in a warming world.”

New science
- A study published in One Earth found that the “planetary boundary” of ecosystem integrity may have already been breached on up to 60% of the Earth’s land surface. Researchers modelled ecological disruption and found that 38% of the Earth is “already at high risk of degradation”.
- Research in the Proceedings of the National Academy of Sciences found that if global temperatures rise 2.3C above pre-industrial temperatures, soil bacterial and fungal diversity would be reduced by 16 and 19%, respectively. It also found that soil organic carbon would drop by 18% under that level of warming.
- Eating a diet of biodiverse, plant-based foods can have “modest benefits” for both sufficient nutrition and environmental health, according to new research published in Nature Food. The study found that diversity of animal-sourced foods was inversely associated with both greenhouse gas emissions and land use.

Wondering How to Talk About Climate Change? Take a Lesson from Bad Bunny
Sydney, Thursday 19 March 2026 — In response to escalating attacks on gas fields in the Middle East, including Israeli strikes on Iran’s giant South Pars gas field and Iranian retaliations on gas fields in Qatar and Saudi Arabia, the following lines can be attributed to Solaye Snider, Campaigner at Greenpeace Australia Pacific:
“The targeting of gas fields across the Middle East is a perilous escalation that reinforces just how vulnerable our fossil-fuelled world really is.
“Oil and gas have long been used as tools of power and coercion by authoritarian regimes. They cause climate chaos and environmental pollution and they drive conflict and war. The energy security of every nation still hooked on gas, including Australia, is under direct threat.
“For countries that are reliant on gas imports, like Sri Lanka, Pakistan and South Korea, this crisis is just getting started. It can take months to restart a gas export facility once it is shut down, meaning the shockwaves of these strikes will be felt for a long time to come.
“It is a gross and tragic injustice that while civilians are killed and lose their homes to this escalating violence, and families struggle with a tightening cost-of-living, gas giants like Woodside and Santos have seen their share prices surge on the prospect of windfall war profits.
“We must break this cycle. Transitioning to local renewable energy is the way to protect Australian households from the inherent volatility of fossil fuels like gas.”

DeBriefed 20 March 2026: Energy crisis deepens | Brazil’s new climate plan | New Zealand climate case
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.”
