Forest destruction in the tropics eased by over a third in 2025, thanks in large part to Brazil’s stronger environmental protection which drove forest loss not caused by fires to a record low in the country, an annual survey showed.
In 2025, the world lost 4.3 million hectares of tropical primary rainforest – an area roughly the size of Denmark, according to data from the University of Maryland hosted on Global Forest Watch. That is 36% lower than in 2024 when climate-fuelled fires pushed forest disappearance to a record high.
Elizabeth Goldman, co-director of Global Forest Watch at the World Resources Institute (WRI), said the drop was “encouraging” and proved what “decisive” government action can achieve. But she cautioned that part of the decline reflected “a lull” after an extreme fire year and forest destruction remains far too high to meet international goals to protect forests and limit global warming to acceptable levels.
Deforestation was 70% higher than it needed to be in 2025 to meet a global pledge to halt and reverse deforestation by 2030, which 145 countries first committed to at COP26 nearly five years ago, the report said. Brazil, which holds the COP30 presidency, has promised to deliver a global roadmap guiding countries toward that goal before this year’s UN climate summit.
“Achieving this goal in the coming years will not be easy as forests become more vulnerable to climate change and as humanity’s growing demand for food, fuel and material sourced from forests in the land they stand on continues to grow,” Goldman told journalists.
Agriculture, fires cause most losses
Primary tropical forests – such as the Amazon in Latin America, the Congo Basin and rainforests in Southeast Asia – are critical carbon sinks that help regulate the global climate by absorbing vast amounts of planet-heating CO2. Their loss weakens one of the world’s most important defences against planetary heating.
Agricultural expansion, driven both by industrial agribusinesses and shifting cultivation for subsistence, returned to being the leading cause of forest destruction in the tropics last year, the Global Forest Watch analysis found. After hitting a record high in 2024, fires – which are usually started by humans – still contributed to around a third of forest destruction in those critical regions.
Climate change is increasing fire risk in the tropics by creating hotter, drier conditions that allow blazes to spread more easily.
Lula’s policies drive progress in Brazil
Trends in global forest destruction are significantly influenced by what happens in Brazil, home to the world’s largest remaining rainforest. In 2025, the South American nation recorded a 42% fall in primary forest loss and its lowest-ever rate of forest loss caused by reasons other than fire.
Analysts said Brazil’s progress in tackling forest loss is a result of the stronger environmental protection and enforcement actions introduced since President Luiz Inácio Lula da Silva returned to office in 2023, after years of budget cuts and policy rollbacks under his pro-business predecessor Jair Bolsonaro.
Lula’s administration revived the Action Plan for the Prevention and Control of Deforestation in the Legal Amazon (PPCDAm), an anti-deforestation framework that coordinates actions across federal agencies and promotes strengthened monitoring, commodities tracking and support for sustainable livelihoods.
The Brazilian government also beefed up the activities of the federal environmental agency Ibama, which between 2023 and 2025 issued 81% more infraction notices and 64% more fines than in the previous two-year period.
“Brazil’s progress shows what’s possible when forest protection is treated as a national priority,” said Mirela Sandrini, executive director of WRI Brasil, adding that the success is derived from building partnerships between the government, civil society, academia, local communities and the private sector.
Neighbouring Amazon country Bolivia recorded the second-highest amount of primary forest loss in the world last year, despite being home to a fraction of the forest held by other rainforest nations like Indonesia or the Democratic Republic of Congo (DRC).
Fires, likely started by humans, were the main cause of forest destruction in Bolivia, alongside the expansion of cattle ranching and crops such as soy and maize, the WRI analysis said.
Forest loss also remained high last year in countries including Peru, Laos and the DRC.
Malaysia and Indonesia showed stable and relatively low levels of forest loss compared to the highs reached in the mid-2010, although experts said Jakarta’s plans to massively expand food and energy production risk threatening the progress seen in the past decade.
Global policies and cash needed
Analysts said protecting the world’s remaining tropical forests will depend not only on national political leadership but also on global policy and financial developments.
Those include the creation of the Tropical Forest Forever Facility (TFFF), a major new rainforest protection fund launched by Brazil at COP30. The mechanism, which gives financial rewards to countries that keep trees standing, has been billed as an historic opportunity to finance forest production. But it is far from raising the $125 billion of public and private investment needed for it to reach a meaningful scale and is unlikely to start making payments until 2028.

How a global roadmap can meet the promise to halt deforestation
Meeting the goal requires political will and a pathway that brings together efforts and drives implementation. An international roadmap can deliver this -
UK imports of “green” jet fuel linked to Amazon deforestation
A Texas refinery shipping sustainable aviation fuel to Europe has sourced beef tallow with links to a meatpacking firm fined over illegal cattle purchases
After failing to secure a negotiated agreement on forest protection at COP30, Brazil promised it would deliver this year a global roadmap charting a course to end deforestation by 2030.
The COP30 presidency said it has received 177 contributions from governments, UN agencies, business groups and civil society with suggestions on what the document should include.
What countries want in the roadmap
The Coalition of Rainforest Nations, which includes 50 countries, wants the roadmap to adopt a “global carbon budget” lens, mapping out region by region where CO2 emissions cuts are most urgent and where existing forest carbon stocks must be protected.
The negotiating bloc also wants finance, including from carbon markets, to be given a prominent space in the document, which will need to obtain broad support from governments to be effective. Without it, the roadmap “risks becoming yet another [plan] collecting dust on the shelves of posterity”, its submission said.
Colombia said interventions should focus on tackling the root causes of deforestation, pointing out that forest loss in the country is concentrated in regions afflicted by deep inequalities, high levels of poverty and the widespread presence of organised crime.
Indonesia wants the roadmap to function as a collaborative platform that “strengthens partnerships”, but warns that international initiatives should “avoid unilateral measures that may undermine trust and effective cooperation”, a thinly veiled rebuke of the European Union’s deforestation regulation.
In its submission, the United Kingdom said the roadmap should focus on a small number of “critical interventions” that can unlock the greatest progress, such as securing legal land rights for Indigenous communities, encouraging sustainable land use and introducing demand-side measures to promote deforestation-free products.
Meanwhile, Russia voiced its opposition to the creation of a “universal roadmap” to end deforestation, saying it instead wants to see a “dedicated dialogue” on forests where countries just exchange best practices.

Analysis: Energy-efficient air conditioning could save Indian homes 69bn rupees a year
More energy-efficient air-conditioning units could, together, save Indian households ₹69bn ($724m) a year, according to new analysis by Carbon Brief.
Climate change-induced extreme heat is driving up the use of air conditioning across the country, as people try to cope with record-breaking temperatures.
This demand, however, is straining the country’s power grid and raising emissions.
On 21 May 2026, India’s power demand reached a record 270 gigawatts (GW), fuelled by a heatwave sweeping across the country and a surge in air-conditioning demand.
Carbon Brief’s analysis shows that, if the roughly 15m households expected to buy a new air conditioning (AC) unit this year bought a “five-star” rated one instead of a “two-star”, it would cut carbon dioxide (CO2) emissions by nearly 5m tonne (Mt).
The installation of AC units in India is currently uneven and ongoing challenges remain, predominantly around the cost of the technology.
Below, Carbon Brief looks at what more energy-efficient models would mean for India’s emissions and household electricity savings, as well as opportunities and barriers to cooling access.
Record heat
Historically, India has had one of the lowest levels of access to cooling in the world. As the nation continues to see an increasing number of heatwave days, this is shifting.
For example, India saw record-breaking heat in 2024 and nearly 14m air conditioners sold – up from 10m in 2023.
Between 2021 and 2023, AC sales volumes increased by more than 25% year-on-year in India.
While solar power is playing an increasing role in meeting the daytime electricity demand from these units, coal power plays a significant role in powering air conditioners on warm nights.
By 2037, India’s space-cooling demand was expected to grow nearly 11-fold in a business-as-usual scenario compared to 2017, according to the government’s 2019 India Cooling Action Plan (ICAP).
According to a World Bank study, this would mean a new air-conditioning unit is bought every 15 seconds in India. There would also be a 435% increase in annual greenhouse gas emissions related to air conditioning in the country over the next two decades.
The chart below shows the ICAP’s estimated rise in air conditioner units in India from 2021 to 2037. The blue line represents a high-growth scenario, while the green line corresponds to a low-growth scenario.
Growing demand
Despite the upswing in installations over recent years, it remains rare for households to have access to air conditioning in India.
According to India’s national sample survey in 2020-21, only 4.9% of Indian households owned air conditioning, with ownership concentrated among the urban rich. As of 2024, this had increased to around 8%.
(Ownership of evaporative air coolers is significantly higher than it is for air conditioning, particularly in the arid north and central Indian states, where humidity is low.)
Dr Nikit Abhyankar, an associate adjunct professor at the Goldman School of Public Policy at the University of California Berkeley, tells Carbon Brief that India is set to add between 100-150m new air conditioners in the next 10 years, which could go up to 200m “if you factor in the crazy heatwaves”.
According to his research, the two factors that drive “dramatic” sales of ACs are income and extreme temperatures.
He tells Carbon Brief:
“The moment you cross a specific income threshold, the first appliance you buy is an air conditioner, no matter whether it’s hot or not. And the moment there are extreme temperatures, the next summer, you see a huge wave of new ACs being purchased.”
With that in mind, he says India offers a “classic lock-in opportunity”, since 90% of the air conditioners that will exist in 2040 have yet to be purchased, particularly given the tendency among Indian users to repair and reuse units. Abhyankar continues:
“That’s why making sure that first AC purchase is the most efficient one is very important in India, because that AC is not going out of the market in seven years.”
Energy-efficient units
With the number of air-conditioning units in India on the rise, ensuring they are as energy-efficient as possible could save households money, while cutting emissions and electricity demand.
India’s Bureau of Energy Efficiency (BEE) mandates star ratings for air conditioners to indicate their efficiency. It uses a metric called the Indian seasonal energy efficiency ratio (ISEER), which is based on an India-specific temperature distribution.
Ratings range from one to five stars, with the latter being the most energy-efficient.
According to the International Energy Agency (IEA), three-star units “dominate” India’s air-conditioning market, “possibly due to [up-front] cost considerations”, while four- and five-star units account for a minority of sales.
The chart below shows AC production volumes in India between 2019 and 2023 by energy-efficiency star rating, according to the IEA.
Carbon Brief analysis finds that buying a five-star air conditioner could cut the emissions associated with generating electricity to run the unit by around 300 kilograms (kg) of CO2 per year, when compared to a two-star unit.
As such, if all 15m air-conditioning units expected to be sold in 2026 were five-star, it could save 5MtCO2 annually.
This is roughly equivalent to the emissions from an average-sized coal-fired power plant, the analysis shows.
In a year, the lower electricity demand from more efficient units could mean ₹69bn ($724m) in cost savings for consumers, as shown in the chart below. Each affected household could save ₹4,600 ($48) annually on their bills.
There are also significant savings from five-star units compared with three-stars, amounting to around 150kgCO2 and ₹2,300 ($24) per household per year.
Carbon Brief’s illustrative analysis is supported by a new working paper from the India Energy and Climate Center (IECC) at UC Berkeley, which looks at the longer-term impact of AC demand on electricity demand and emissions, as well as grid investment costs and consumer savings.
Released in May 2026, it says that room air conditioners already account for nearly a quarter of India’s peak electricity demand (60-70GW).
The authors estimate that AC-driven peak power demand could reach 120GW by 2030 and 180GW by 2035, pushing India’s power grid beyond its capacity. They warn:
“Even with all under-construction generation and storage projects online, power shortages are expected as early as 2028.”
Sustained energy-efficiency improvements, however, could reduce this cooling-driven peak power demand by 10GW by 2030 and 47GW by 2035.
They estimate that these improvements could help avoid nearly $80bn in power infrastructure investments and deliver $9-25bn in consumer savings between 2028 and 2035, while reducing emissions by 12MtCO2 per year by 2030.
Rolling out five-star units
While there are emissions and cost benefits to five-star air-conditioning units compared to the alternatives, the higher upfront costs can still present a barrier.
These more energy-efficient units can pay for their higher purchase price over a three-year period, but on average cost ₹5,000 to ₹8,000 ($52-84) more upfront than a three-star unit.
Researchers at the Indian climate thinktank Sustainable Futures Collaborative (SFC) called on Indian state and national governments to create a “highly-targeted active cooling” programme last year.
They recommended deploying a subsidy or a large-scale purchase programme that allows families to buy energy-efficient air conditioners. This, they said, must be targeted at portions of Indian cities with the highest heat risk, determined by the vulnerability assessments of their heat action plans.
Climate adaptation researcher at King’s College London and SFC author Aditya Valiathan Pillai tells Carbon Brief:
“Commit money to air conditioning for the poorest-of-the-poor: subsidise ultra-efficient ACs and electricity, but give them cool air at the cheapest possible, most efficient rate.
“Because these are the people running the economy, which is not going to function in a heatwave if these people are dying or unable to work.”
Methodology
Carbon Brief’s analysis is based on official energy consumption, power pricing and emissions data from different ministries and government institutions.
It uses BEE’s “search and compare” tool to list all five-star and three-star “variable speed” or “inverter” air conditioners, given their enhanced efficiency and ability to regulate humidity.
This was then filtered to air conditioners with a capacity of 1.5t, which studies say are most preferred by Indian households.
Using the same tool, Carbon Brief then listed all “fixed speed” two-star ACs of a similar capacity (1.45t to 1.55t), given that these account for the majority of two-star ACs available on the market and favoured by renters.
Based on expert estimates, the analysis lists the energy consumption of each of these key categories in kilowatt-hours (kWh) and added 15% to account for losses in power transmission and distribution.
The carbon intensity of Indian electricity is specified by the CO2 baseline database published by India’s Central Electricity Authority in November 2025.
The number of hours per year a household’s air conditioning runs is estimated at 1,600 hours by the BEE.
Carbon Brief uses a marginal electricity tariff of ₹10 per kWh to calculate annual electricity consumption costs.
This is because average electricity tariffs vary significantly from state to state, but especially by energy consumption “slabs”, with AC use pushing bills into higher-tariff rates.
For instance, in Maharashtra, electricity tariffs for domestic households range from ₹1.52 per unit for below-poverty-line households to ₹16.64 per unit for homes using more than 500 units of electricity.
Savings from higher energy efficiency, therefore, reduce electricity consumption in the highest electricity tariff block, where rates are the most expensive.
Cooling hours
Air-conditioner usage varies across India’s climatic zones. The ISEER metric that underpins star ratings estimates that, on average, a household air conditioner runs for 1, 600 hours a year.
This estimate is based on 2014 weather data for 54 cities across India, to see how many hours in a year temperatures exceed 24C.
Refrigerant emissions
The analysis only accounts for emissions from electricity generation and does not factor in “fugitive” emissions from refrigerant leaks.
These are significant, given that refrigerants are greenhouse gases that can have hundreds of times more warming potential than CO2.
According to a study published by climate thinktank iForest last year, Indian households with air conditioning are refilling their refrigerants more frequently than the global average.
It estimates that greenhouse gas emissions from refrigerant release from India’s air conditioners were 52Mt of CO2 equivalent (CO2e) in 2024, likely to increase to 84MtCO2e by 2035.
Cooling access and population data
Government estimates vary on how many Indian households do not own a single air conditioner, with little publicly available data differentiating between cooling devices and a delayed national census.
India’s national sample survey, published in 2020-21, is the only one of its kind in recent years to separate air-conditioner ownership from air cooler ownership, estimating that only 4.9% of all Indian households owned an air conditioner.

For years, the dominant story on coral reefs has been one of inevitable loss, with news headlines focusing on mass bleaching, ecosystem collapse, and catastrophic tipping points. As ocean temperatures continue to rise, many people have come to see the decline of the world’s reefs as unavoidable.
The threats are real and urgent, but new evidence points to a more complicated and useful conclusion: some reefs still have a meaningful chance to survive and recover, provided they are protected.
A major new analysis, published today with the support of Bloomberg Philanthropies, identifies more than 165,000 square kilometers of coral reefs, across 71 countries and 100 territories and jurisdictions, with the strongest potential to withstand and recover from climate impacts.
Drawing on more than 45,000 coral surveys, along with decades of climate and ocean data, the research finds that three times more reefs may be capable of surviving the climate crisis than previously understood. That has major implications for reef-dependent communities, food security, coastal protection, fisheries, tourism, and national economies.

The Pacific made history in the courts – now we must do it in the negotiations
Legal clarity alone will not lead to reduced emissions, more finance or stronger national climate plans – political will is key to meeting states’ obligations
Essential natural infrastructure for communities
The findings make clear that reefs will not all respond to climate impacts in the same way. Some are located in rare underwater cool spots that can help shield them from extreme heat. Some show greater resistance to bleaching and other climate-related stress. Others recover more quickly after severe disturbances. These differences matter because they show where protection can have the greatest long-term impact.
More than 500 million people depend on reefs for food, livelihoods, and coastal protection. For those communities, climate-resilient reefs are not an abstract conservation priority. They are essential natural infrastructure. They help protect coastlines, sustain fisheries, support local economies, and reduce climate risk. Because ocean currents move coral larvae and marine life between reef systems, some of these reefs may also help regenerate wider reef ecosystems after climate shocks.
This should change how governments, funders, and conservation partners prioritize action.
Climate change remains the greatest long-term threat to coral reefs. At the same time, many of the pressures pushing reefs closer to collapse are immediate and local. Sewage pollution, deforestation, agricultural runoff, destructive fishing practices, and poorly managed coastal development continue to damage reefs that are already under stress. Recent research shows that water pollution and fishing pressure are now among the leading local threats affecting nearly two-thirds of the world’s coral reefs.
These pressures can be reduced. Governments and local partners are already working to improve reef management, cut pollution, strengthen enforcement, and protect critical ecosystems. Those efforts need to move faster, alongside much stronger action to reduce greenhouse gas emissions.
Prioritising climate-resilient reefs
The new maps of climate-resilient reefs give governments, communities, and reef managers a clearer basis for action. They show where reefs have the strongest potential to persist over time, and where protection can deliver the greatest benefits for people, coastlines, and economies.
Right now, only around 28 percent of the identified climate-resilient reefs fall within protected or conserved areas. If these reefs are among the most capable of surviving climate impacts and helping regenerate broader reef systems, they should be prioritized for protection, management, and investment.
The case for action is practical as well as ecological. Healthy reefs can reduce wave energy by up to 97 percent, helping protect coastlines from storms, flooding, and erosion. They support fisheries that feed millions of people, sustain tourism jobs and local economies, and help reduce climate risk for vulnerable coastal communities.
For many families, a healthy reef means food, income, and protection when storms hit. For Indigenous Peoples and coastal communities, reefs are also tied to culture, heritage, identity, and traditional knowledge systems.
Ocean conservation must catch up
Governments are beginning to recognize the urgency of protecting climate-resilient reefs. At last year’s UN Ocean Conference in Nice, 11 countries signed a declaration committing to stronger protection of these reefs, including action to address destructive fishing, pollution, and unsustainable coastal development.
As leaders meet in Kenya this week to discuss the challenges facing the world’s ocean, more governments should join the declaration and help build a broader coalition committed to safeguarding these critical ecosystems.
As coral reefs pass tipping point, ocean protection rises up political agenda
Some countries are already showing what this leadership can look like. Brazil has included corals in its national climate plans. The Bahamas is embedding reef protection into national policy and local stewardship systems. The declaration offers a way to build on these efforts and scale them globally.
But commitments will not be enough. Success will depend on implementation. That means stronger protection and management, reduced local pressures, increased investment, and meaningful support for the Indigenous Peoples and local communities stewarding these ecosystems.
The science is clear. Many reefs still have the capacity to persist and recover. The question is whether policy and investment will move quickly enough to protect them, so they can continue sustaining communities, economies, and coastlines for generations to come.

Months After a Jet Fuel Leak, No Agency Tested Waters Downstream of Piscataway Creek. So Community Groups Are Doing It Themselves.
Authorities that manage the Potomac River tributary did not sample the stretch where residents fish and recreate. One Indigenous leader sees the lack of response as part of a pattern of ongoing neglect.
In the five months after jet fuel started leaking from Joint Base Andrews into Piscataway Creek, no agency tested the water or sediment some 20 miles downstream, where the creek empties into the Potomac River and the shoreline community and anglers gather to fish and boat along the riverbank.
