June 25, 2026 -- Today, Climate TRACE reported that global greenhouse gas (GHG) emissions for the month of April 2026 totaled 4.9 billion tonnes CO₂e. This represents an increase of 0.1% vs. April 2025. Total global year-to-date emissions are 20.1 billion tonnes CO₂e. This is 0.1% lower than 2025's year-to-date total for the same time period. Global methane emissions in April 2026 were 33.5 million tonnes CH₄, an increase of 0.1% vs. April 2025.

Data tables summarizing GHG and primary particulate matter (PM2.5) emissions totals by sector, country, and the top 100 urban areas for April 2026 are available for download here.

Greenhouse Gas Emissions by Country: April 2026

Climate TRACE's preliminary estimate of April 2026 emissions in China, the world's top emitting country, is 1.4 billion tonnes CO₂e, a decline of 3.9 million tonnes of CO₂e, or 0.3% vs. April 2025.

Of the other top five emitting countries:

• United States emissions increased by 1.0 million tonnes CO₂e, or 0.2% year over year;

• India emissions increased by 0.6 million tonnes CO₂e, or 0.2% year over year;

• Russia emissions declined by 0.2 million tonnes CO₂e, or 0.1% year over year;

• Indonesia emissions remain unchanged.
  In the EU, which as a bloc would be the fourth largest source of emissions in April 2026, emissions increased by 2.3 million tonnes CO₂e compared to April 2025, or 0.8%.

Data on all other countries and territories are available in our Country/Territory Inventory.

Greenhouse Gas Emissions by Sector: April 2026

Greenhouse gas emissions increased in April 2026 vs. April 2025 in buildings, power, and waste, and decreased in fossil fuel operations, manufacturing, and transportation. Buildings saw the greatest change in emissions year over year, with emissions increasing by 2.4% as compared to April 2025.

• Agriculture emissions were 603.9 million tonnes CO₂e, unchanged vs. April 2025;

• Buildings emissions were 308.5 million tonnes CO₂e, a 2.4% increase vs. April 2025;

• Fluorinated gases emissions were 145.0 million tonnes CO₂e, unchanged vs. April 2025;

• Fossil fuel operations emissions were 790.7 million tonnes CO₂e, a 0.1% decrease vs. April 2025;

• Manufacturing emissions were 866.7 million tonnes CO₂e, a 0.7% decrease vs. April 2025;

• Mineral extraction emissions were 17.4 million tonnes CO₂e, unchanged vs. April 2025;

• Power emissions were 1,256.3 million tonnes CO₂e, a 0.8% increase vs. April 2025;

• Transportation emissions were 753.3 million tonnes CO₂e, a 1.0% decrease vs. April 2025;

• Waste emissions were 169.7 million tonnes CO₂e, a 0.7% increase vs. April 2025.

Greenhouse Gas Emissions by City: April 2026

The urban areas with the highest total GHG emissions in April 2026 were Shanghai, China; Tokyo, Japan; Los Angeles, United States; New York, United States; and Houston, United States.

The urban areas with the greatest increases in absolute emissions in April 2026 as compared to April 2025 were Tehran, Iran; Chicago, United States; Opole, Poland; Butibori, India; and Mannheim, Germany. Those with the largest absolute emissions declines between this April and last April were Dubai, United Arab Emirates; Detroit, United States; Holland, United States; Newcastle, Australia; and Rotterdam [The Hague], Netherlands.

The urban areas with the greatest increases in emissions as a percentage of their total emissions were Butibori, India; Uruguaiana, Brazil; Mansa Nagar, India; Zenica, Bosnia and Herzegovina; and Opole, Poland. Those with the greatest decreases by percentage were Lufeng, China; Yenakiieve, Ukraine; Monclova, México; Mariupol, Ukraine; and Lueyang, China.

RELEASE NOTES Revisions to existing Climate TRACE data are common and expected. They allow us to take the most up-to-date and accurate information into account. As new information becomes available, Climate TRACE will update its emissions totals (potentially including historical estimates) to reflect new data inputs, methodologies, and revisions.

With the addition of April 2026 data, the Climate TRACE database is now updated to version V5.8.0. In this release, the iron and steel and other metal sectors had minor updates to their capacity estimates; the water reservoirs sector fixed a bug to correct its Sentinel space resolution; and the solid waste disposal sector improved its model to estimate incoming waste and uncertainty.

A detailed description of data updates is available in our changelog here.
