Total global emissions in the first half of 2025 are 30.99 billion tonnes COâ‚‚e and 5.12 billion tonnes COâ‚‚e for the month of June 2025. For all updates to Climate TRACE country-, state-, city-, sector-, and asset-level data, visit climatetrace.org.
OAKLAND, Calif., Aug. 28, 2025 /PRNewswire-PRWeb/ -- Today, Climate TRACE reported that total global emissions in the first half of 2025 are 30.99 billion tonnes COâ‚‚e. This is 0.13% higher than emissions were in the first half of 2024. Global greenhouse gas emissions for the month of June 2025 totaled 5.12 billion tonnes COâ‚‚e. This represents an increase of 0.29% vs. June 2024. Global methane emissions in June 2025 were 34.82 million tonnes CHâ‚„, an increase of 0.49% vs. June 2024.

Lookback: Global Greenhouse Gas Emissions for the First Half of 2025
In the first half of 2025, the sector driving the most growth in emissions was fossil fuel operations, where emissions rose by 1.5% (an increase of 77.65 million tonnes of COâ‚‚e). The United States accounted for more than half of that increase. Manufacturing emissions also rose in the first half of 2025, growing by 0.3% (an increase of 18.75 million tonnes of COâ‚‚e), led by increases in India, Vietnam, Indonesia, and Brazil.
Meanwhile, global power sector emissions saw the biggest decline in the first half of 2025, falling by 0.8% (a decrease of 60.27 million tonnes of COâ‚‚e), driven almost entirely by declines in China and India, where power emissions were 1.7% lower and 0.8% lower than their totals in the first half of 2024, respectively.
The first half of 2025 shows small but positive progress on decarbonization in , , and . China's emissions decreased 45.37 million tonnes COâ‚‚e, or 0.51% compared to the first half of 2024. Mexico's emissions decreased 7.78 million tonnes COâ‚‚e, or 1.71% compared to the first half of 2024. Australia's emissions decreased 6.56 million tonnes COâ‚‚e, or 1.51% compared to the first half of 2024. However, some of the world's other major emitting economies, including the United States, India, the EU, Indonesia, and Brazil, saw emissions rise in the first half of 2025.
- emissions increased by 48.57 million tonnes COâ‚‚e, or 1.43% compared to the first half of 2024;
- emissions increased by 4.44 million tonnes COâ‚‚e, or 0.21% compared to the first half of 2024;
- emissions increased by 2.90 million tonnes COâ‚‚e, or 0.15% compared to the first half of 2024.
- emissions increased by 3.06 million tonnes COâ‚‚e, or 0.39% compared to the first half of 2024;
- emissions increased by 9.84 million tonnes COâ‚‚e, or 1.24% compared to the first half of 2024.
Greenhouse Gas Emissions by Country: June 2025
Climate TRACE's preliminary estimate of June 2025 emissions in , the world's top emitting country, is 1.46 billion tonnes CO₂e — an increase of 0.92 million tonnes of CO₂e or 0.06% vs. June 2024.
Of the other top five emitting countries:
- emissions increased by 4.89 million tonnes COâ‚‚e, or 0.86% year over year;
- emissions declined by 0.11 million tonnes COâ‚‚e, or 0.03% year over year;
- emissions increased by 0.95 million tonnes COâ‚‚e, or 0.38% year over year;
- emissions increased by 0.43 million tonnes COâ‚‚e, or 0.33% year over year.
In the EU, which as a bloc would be the fourth largest source of emissions in June 2025, emissions declined by 1.80 million tonnes COâ‚‚e compared to June 2024, or 0.58%.
Greenhouse Gas Emissions by Sector: June 2025
Greenhouse gas emissions increased in June 2025 vs. June 2024 in fossil fuel operations, manufacturing, transportation, and waste, and decreased in power. Fossil fuel operations saw the greatest change in emissions year over year, with emissions increasing by 1.85% as compared to June 2024.
- emissions were 641.40 million tonnes COâ‚‚e, unchanged vs. June 2024;
- emissions were 285.59 million tonnes COâ‚‚e, unchanged vs. June 2024;
- emissions were 137.71 million tonnes COâ‚‚e, unchanged vs. June 2024;

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 June 2025 data, the Climate TRACE database is now updated to version V4.6.0. This release incorporates the most recent FAOSTAT and CEDS data in applicable sectors. The release also reflects updated methodology for non-GHG emissions from glass, cement, and lime production; the addition of N2O emissions across agriculture subsectors and additional refinements to agriculture emissions factors; updated North America and Europe data for Q4 2024 in petrochemicals and oil and gas refining; updated methodology and data for cement and steel production to reflect updated emissions factors; and the addition of 56 steel plants to our database.
