Climate TRACE Data Show Global Greenhouse Gas Emissions Hit a New Record High in 2025 in World Economy News 27/02/2026 Climate TRACE released full-year 2025 emissions data, showing that global greenhouse gas (GHG) emissions increased 0.50% by 303.19 Mt CO2e last year, reaching a new high of 60.63 Bt CO₂e. Global methane emissions increased 1.03% or 4.2 Mt CH4 in 2025, rebounding from a decline in 2024 to set a new annual record of 412.59 Mt CH4, surpassing the previous record set in 2023. Key Insights from 2025 Emissions Data: Despite a small decline in power sector emissions, fossil fuel operations, transportation, manufacturing, and buildings all nudged global greenhouse gas emissions higher. Oil and gas production was the subsector with the largest jump in emissions, increasing 4.1%. The biggest movers in the power sector were China, India, and the US. For the first time since at least 2015, emissions from China’s power sector decreased year over year, but that decline was offset by an equivalent increase in US power emissions. Meanwhile, India’s power sector emissions fell for the first time since 2020. Road transportation emissions increased globally, but have dropped in Nordic countries where electric vehicle (EV) adoption is high. All 2025 emissions data — which include monthly and annual totals for all major greenhouse gases and eight major non-GHG co-pollutants across 10 sectors, 64 subsectors, every country, state/province, county, more than 9,000 cities, and more than 744 million individual assets — are now publicly available at ClimateTRACE.org. The analysis below focuses on non-land use, land-use change, and forestry (LULUCF) emissions — full LULUCF data are available on our website. Data highlights for the month of December 2025 are also included below. Global Trends Climate TRACE data show that in nearly every month of 2025, global emissions were higher than they were in 2024. In 2025, Russia’s emissions increased the most of any country in the world, while India had the largest drop in emissions. China and the United States, the world’s top two emitters, saw their emissions stay relatively flat in 2025, ticking up slightly in each country. Despite the relatively small rate of increase, China and the US ranked second and sixth, respectively, for largest increase in absolute emissions. Across 10 major emitting sectors, the most significant growth in emissions in 2025 came from fossil fuel operations, with emissions rising 1.56% or 151.57 Mt CO2e. Emissions also rose in the transportation, manufacturing, and buildings sectors last year. The power sector continues to be the largest source of global emissions in 2025 (26% of total emissions). Climate TRACE data show that global power sector emissions fell slightly, decreasing by 0.13% or 20.31 Mt CO2e in 2025 — the first decline since the COVID-19 pandemic. Most of the decline came from electricity generation in India and China (more on this in the section on clean energy uptake below), but Russia, Australia, and Poland also saw significant drops in their power sector emissions. Much of the emissions increase in fossil fuel operations came from higher oil and gas production emissions, which rose 4.1% or 163.2 Mt CO2e in 2025. This was the largest increase in emissions among the 64 subsectors tracked by Climate TRACE. Russia’s oil and gas production emissions were responsible for the majority of that increase, though other countries including Kazakhstan, China, Saudi Arabia, a
