A new Greenpeace International report, Toxic Skies: How Agribusiness is Choking the Amazon, reveals how fires linked to industrial agriculture are turning the forest’s air toxic during the dry season. The findings are a stark warning that the Amazon’s crisis is not only about trees. It is about the air millions of people breathe, and the health of our shared planet.
When the sun rises over Porto Velho, on the edge of the Brazilian Amazon, it does not pierce through the mist. It struggles through the smoke. For months each year, the air fills with the haze of fires deliberately set to clear forests for cattle or to renew pasturelands. What was once the world’s greenest ecosystem often breathes air contaminated with higher levels of toxic particles than Beijing, São Paulo or Santiago, according to the report.
What the study found
Researchers monitored air quality in two Amazonian cities, Porto Velho (Rondônia) and Lábrea (Amazonas), combining satellite and ground-based data. The results are alarming:
- During the record-breaking fire season of 2024, levels of fine particulate matter (PM2.5) exceeded WHO daily health guidelines by more than 20 times.
- Even in 2025, a year with far fewer fires, the air still exceeded the guidelines by over six times.
- Between 2019 and 2024, the annual average pollution in Porto Velho was higher than in major global megacities, largely driven by sharp increases in PM2.5 levels during the fire season.
- Around 75% of burned areas around Porto Velho in 2024 are used as pasture for cattle production, showing that most fires are linked to grazing land use.
- More than half of the total burned area in 2024 in the Amazon biome falls within a 360km radius around the facilities of Brazil’s largest meatpacker, JBS. Meatpackers such as JBS do not effectively prohibit and monitor the deliberate use of fire in their supply chains – leaving meatpackers exposed to the risk of indirect or direct supply chain links, including through maintaining business relations, with farms in burned areas.
This is not a natural disaster. It is a business model that profits from destruction and public suffering.
Breathing in the crisis
The Amazon’s fires are not acts of nature. They are deliberately lit to clear forest or renew pastures for cattle. And, behind every statistic are human stories. Hilda Barabadá Karitiana, from the Karitiana Indigenous Territory near Porto Velho, describes how her community lives with the smoke:
During the dry season, the air becomes thick with smoke. Even when the fire is far away, we feel it. Sore throats, constant coughing, and irritated eyes. It affects everyone.– Hilda Barabadá Karitiana
For people like Hilda, the smoke is not just a seasonal nuisance. It is a public health emergency. Exposure to high levels of PM2.5 causes respiratory infections, heart disease and asthma, especially among children and older adults. The air itself has become an agent of crisis.
Debunking Myths
✘ Fires in the Amazon region occur naturally and are beneficial for the ecosystem.
Fires in the Amazon region are caused by human activity and are highly destructive to the rainforest ecosystem.
✘ Fires in the Amazon happen because of logging.
Vast areas of the Amazon biome are set on fire to make way for cattle ranching.
A turning point before COP30
This year’s COP30, hosted in Belém, on the edge of the Amazon, will be the first UN Climate Summit held inside a tropical forest. It is an opportunity to put Amazonian voices and air quality at the centre of global climate negotiations and to demand that governments and corporations act.
Chief Zé Bajaga, from the Caititu Indigenous Territory, says:
Here in the Amazon, we face invasion, fires and pollution from companies that profit while our land burns. Those who destroy for money must be held accountable.– Chief Zé Bajaga
What needs to happen now
World leaders need to step up and:
- COP30 should deliver an action plan to implement the UNFCCC’s 2030 target to halt and reverse deforestation and forest degradation of the world’s forests. It’s time to turn commitments into action.
- Governments must urgently regulate the agricultural and financial sectors to ensure their alignment with the Paris Agreement, the Global Biodiversity Framework, and the UN Sustainable Development Goals.
- Governments must ensure the transition to truly ecological and just food systems, an end to deforestation, and the reduction of emissions associated with agriculture, including methane.
- World leaders must ensure funding for real solutions to protect and restore forests by providing finance directly accessible to Indigenous Peoples and Local Communities.
The Amazon’s toxic skies are not inevitable. They are the product of political choices and economic greed. As world leaders prepare for COP30, this is the moment to act.

DeBriefed 12 June 2026: El Niño begins | COP31 hosts eye electrification | Atlantic current monitoring at risk
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
El Niño begins
‘DOMINO WEATHER’: The natural weather phenomenon El Niño, which can raise global heat and “bring domino weather effects across the planet”, is now underway, the US National Oceanic and Atmospheric Administration (NOAA) declared on Thursday, reported the Washington Post. The Japanese Meteorological Administration also identified the start of El Niño on Wednesday, said Bloomberg. According to the Japanese weather agency, the event is “expected to intensify in the coming months and become very strong later in the year, persisting into at least December”, reported the outlet.
‘SUPER EVENT’: BBC News reported that “many forecasts suggest this could end up as a so-called ‘super’ El Niño” and be “among the strongest ever recorded”. It added: “Coming on top of decades of human-caused warming, it could bring another record-hot year – most likely in 2027 – with disruption to weather, food supplies and economies running well into that year.”
COP31 hosts eye electrification
‘35 BY 35’: COP31 hosts Turkey and Australia have called for countries to support a target of electrifying 35% of global energy use by 2035, reported Politico. Speaking at climate talks in Bonn, Germany, Turkish minister Murat Kurum said that electrification would be a “flagship priority” at the COP31 summit, noted the publication. Kurum added that “electrifying daily life, from transport to buildings and industry” could “protect families and businesses from volatile energy markets”, said the outlet.
WASTE AND BUILDINGS: Climate Home News reported that electrification was one of three priorities unveiled by the COP31 hosts, with the other two being waste and buildings. On buildings, the COP31 hosts “quietly overhauled [their] goal”, Climate Home News said. It reported: “An initial press statement on Monday set out a target ‘to achieve at least a 25% increase in energy efficiency in buildings by 2035’. But…on Tuesday, that was replaced with a different goal to ‘reduce energy consumption intensity in the building sector by at least 25% by 2035’.”
‘HARDEST’ CHALLENGE: Elsewhere in Bonn, UN climate chief Simon Stiell said “governments must stop revisiting climate commitments and start delivering on them”, South Africa’s Mail and Guardian reported. It quoted Stiell as saying: “Tackling the global climate crisis is the hardest but most important thing humanity has ever tried to do together…We are not yet where we need to be. But we are somewhere we have never been before.”
Around the world
- ETS EXTRA: The EU has agreed “stronger” price controls on “ETS2”, its planned trading system for heating and transport emissions, according to Reuters.
- OCEAN STRESS: The rate of sea level rise has doubled in 10 years amid “severe and accelerating” pressures on oceans, said a UN report covered by Time.
- CLIMATE MIGRANTS: Donald Trump’s “immigration crackdown is largely targeting people from the countries most vulnerable to displacement from climate-driven disasters”, according to Guardian analysis.
- ULTRA-RICH: Investments by the world’s ultra-rich in 2022 are linked to nearly $1tn in climate damages, according to a Greenpeace Africa analysis covered by BusinessGreen.

Captured
Solar power has overtaken gas in Asia to become the region’s third largest electricity source behind coal and hydropower, according to Carbon Brief analysis of data from the thinktank Ember. Solar became the third largest electricity source for Asia on an annual basis in April 2026, according to the analysis. In the year to April 2026, solar generated 1,727 terawatt hours (TWh), while gas generated 1,711TWh, it added.
Spotlight
Atlantic current monitoring at risk
This week, Carbon Brief reports on how Trump plans could disrupt efforts to track a major ocean current.
The Irminger Sea, a patch of frigid ocean east of Greenland, plays an outsized role in the Earth’s climate.
Here, surface water that has travelled thousands of kilometres from the tropics grows cold and dense enough to sink to the ocean’s depths – a transformation that must occur for the water to begin a long journey back to the southern hemisphere.
This makes the Irminger Sea an “action centre” for the mighty Atlantic Meridional Overturning Circulation (AMOC), the vast system of ocean currents that keeps temperatures in Europe mild.
Last week, the US government announced plans to dismantle ocean moorings installed in the Irminger Sea which, among other things, collect data on the health of the AMOC.
This came as part of a programme to “descope” the Ocean Observatories Initiative, a $368m network of ocean sensors installed in the Pacific and Atlantic oceans.
Two of the moorings earmarked for removal in the Irminger Sea form part of an internationally funded, trans-Atlantic AMOC monitoring array, known as OSNAP, that stretches from Canada to Scotland.
Experts told Carbon Brief the move by the Trump administration highlights the vulnerability of AMOC observation systems around the world. These deep-sea moorings – scattered across the Atlantic – collect real-time data on, among other things, ocean current, temperature, pressure and biochemistry.
Prof Penny Holliday, chief scientific officer of the UK National Oceanography Centre, told Carbon Brief that the OSNAP array, as well as the RAPID array at 26N, are “entirely dependent” on research grants that have to be “continually reapplied for”.
“Funding is perilous all the time,” she said.
A report prepared last month by scientists for Nordic ministers exploring the security of funding for AMOC observing systems warned that RAPID and OSNAP were in “critical condition” and faced “material exposure over an 18-month horizon”. Meanwhile, other key basin-wide and global components of the global AMOC observing system were rated as “at risk”.
It is not just US funding that is uncertain. The report notes, for example, that the five-yearly funding the UK provides to RAPID and OSNAP is “at risk from 2027 due to year-on-year budget reductions” at the Natural Environmental Research Council.
(RAPID is funded by the US and UK, whereas OSNAP is backed by five different countries, with the US contributing half of the total financial support.)
Report co-author Dr Femke de Jong from the Royal Netherlands Institute for Sea Research told Carbon Brief that “continued AMOC observations” are under pressure in “multiple countries”. She said:
“While the risk of a declining AMOC to society is starting to be recognised, there is not yet a system or institution in place to guarantee a way to monitor it.”
AMOC monitoring arrays are still in their infancy – RAPID, the oldest, was launched in 2004. Two decades of data captured so far shows that the AMOC is slowing down. However, scientists will need many more years of data to be able to confidently link the decline to climate change, rather than natural variability in the ocean.
NOC’s Holliday points to the disconnect between scientific and funder timelines:
“The timescale of observations needed in order to be able to detect a climate change signal from the very naturally variable ocean is around 40-60 years…. [And yet], in the Netherlands, they have to apply for a new grant for their ocean moorings every two years. They are going to have to do that for 40 years.
“This is a very inefficient way of getting funding for what should be critical infrastructure.”

Solar has overtaken gas power in Asia to become the continent’s third-largest source of electricity, according to new analysis by Carbon Brief.
The rapid expansion of solar power in nations such as China, India and Pakistan has seen its annual output increase nearly fourfold since 2020.
Asia accounts for around 60% of the world’s solar-power growth in this period, putting the continent at the heart of the global solar boom.
Coal and hydropower remain Asia’s largest sources of electricity, generating roughly 52% and 12% of the continent’s power each year, respectively.
Yet despite expectations that gas power would undergo “explosive growth” in the region, output has stalled due to supply disruptions, relatively high gas prices and growth in clean alternatives.
In contrast, solar has surged, generating some 1,727 terawatt hours (TWh) of electricity in the 12 months to April 2026.
As the chart below shows, this pushes it just ahead of gas, which generated 1,711TWh over the same period and has remained roughly flat for the past several years.
The milestone reflects wider trends in the global electricity mix, with monthly generation from both wind and solar surpassing gas generation globally for the first time in April 2026.
Asia’s solar expansion has been driven largely by China, which accounts for nearly three-quarters of the growth in the region’s output since 2020.
Record installations in 2025 took China’s cumulative installed capacity to 1.2 terawatts (TW) by the end of the year.
China also dominates global solar supply chains, hosting more than 80% of solar manufacturing capacity.
This means it has played an important role in enabling solar deployment in other Asian countries through cheap solar-panel exports. Amid the energy crisis sparked by the Iran war, Chinese solar exports to Asia doubled to reach a record 39 gigawatts (GW) in March 2026.
Meanwhile, Asian countries have faced a number of challenges in expanding gas-power capacity. Most of these nations are reliant on imported liquified natural gas (LNG) to support their gas-power projects.
Around 81GW of planned gas capacity in Asia was cancelled in 2022 and 2023, amid LNG supply disruptions and price spikes following Russia’s invasion of Ukraine.
LNG import terminals and pipelines have faced delays and cancellations in south Asia and South Korea as a result of rising fuel and construction costs, as well as weak demand for gas power.
Global gas turbine shortages have also delayed plans to build new gas-power plants in Vietnam and the Philippines.
While Asia’s gas-power capacity increased by 22% between 2019 and 2024, gas-fired generation has only increased by a modest 6% over the same period. Existing gas plants are not always operating at high capacities, as gas is outcompeted by other fuels.
These trends are not uniform across the region, with increased generation in some countries – such as China and Taiwan – being offset by declines in others – such as Japan and India.
Although China has nearly doubled its gas -power generation in the past decade, gas supply issues and high prices make it less competitive than coal and renewables.
The expansion of clean energy has also reduced the need for gas-fired generation in many Asian countries. Pakistan’s widely reported “boom” in rooftop solar is one notable example of this trend.
According to the International Energy Agency (IEA), the latest energy crisis has “renewed gas supply reliability and affordability concerns” among gas-importing countries in Asia, many of which are highly dependent on gas flows through the strait of Hormuz.
Methodology
The figures in this article are based on Ember’s monthly and annual electricity data for Asia.
Annual data was used for the year-end data points, as the coverage is more complete compared to the monthly data.
Rolling annual totals based on monthly data were used to interpolate between the annual data points.
The figures in the chart are based on Ember’s definition of Asia, which covers the following countries: Afghanistan, Armenia, Azerbaijan, Bangladesh, Bhutan, Brunei, Cambodia, China, Georgia, Hong Kong, India, Indonesia, Japan, Kazakhstan, North Korea, Kyrgyzstan, Laos, Macao, Malaysia, Maldives, Mongolia, Myanmar, Nepal, Pakistan, the Philippines, Singapore, South Korea, Sri Lanka, Taiwan, Tajikistan, Thailand, Timor-Leste, Turkmenistan, Uzbekistan and Vietnam.
This does not include some countries that are part of the continent of Asia and that use relatively large amounts of gas, such as Iran, Saudi Arabia, the United Arab Emirates (UAE) and Russia.
