Climate TRACE

THE KEELING CURVE AND MONTHLY CLIMATE TRACE EMISSIONS ESTIMATES Atmospheric concentrations of CO2 have risen steadily since tracking began in 1958. The Keeling Curve shows that change over time. So, how do Climate TRACE emissions estimates track alongside the Keeling Curve? This chart shows monthly Climate TRACE global emissions data (white) alongside monthly concentrations of atmospheric CO2 (blue) going back to 2015 — the first year of Climate TRACE data available. What do you notice?

February 2026 emissions data are live on ClimateTRACE.org. Here are the highlights: 🌏February 2026 total global emissions: 4.9 Bt CO2e (0.7% decrease from February 2025) 🗓️ Year-to-date total through February 2026: 10.2 Bt CO2e 🐄February methane emissions: 33.0 Mt CH4 Read the full release for more of the latest emissions data from Climate TRACE at the link in our bio.

Located on an island with more penguins than people, sources of emissions are slim in Port Lockroy — home to the world’s southernmost post office — but Climate TRACE data reveal clear patterns of seasonal emissions tied to the shipping sector. Port Lockroy is a historic British outpost located on Goudier Island off the Antarctic Peninsula, which is also home to a colony of nearly 1,500 penguins. Tourism is Port Lockroy’s biggest draw, and the Climate TRACE data show a clear rise in shipping emissions during the Antarctic summer in correlation with seasonal visitors. While it is not a major global emitter, this remote location serves as a prime example of the fine detail and granularity the Climate TRACE platform can provide.

This 210 MW solar farm in Rajasthan, India is reducing annual emissions by an estimated 280,000 tCO2e — a great example of how expanding renewable electricity generation is one of the most effective ways to reduce power-sector emissions. If more solar is deployed on the dirtiest grids around the world, it could reduce 9.2 BtCO2e annually. Each megawatt-hour of solar or wind generation lowers the grid’s overall emissions intensity, and prioritizing renewable projects in high-emission power systems accelerates decarbonization and improves air quality.

Agriculture is a top-five contributor to global GHG emissions, yet large-scale cattle operations remain one of the most significant blind spots in climate reporting. In many regions, there is simply no facility-level data on where these emissions are coming from — until now. We sat down with Vasit Sagan, PhD and Derek S. Tesser, PhD from the Remote Sensing Lab at @SLU_official to discuss how their research is powering Climate TRACE’s cattle emissions inventory. By integrating high-resolution remote sensing and foundation AI models, their team is moving beyond static assumptions to map the real-world complexity of livestock. As Vasit Sagan puts it: “These are global datasets about our food supply... built from satellite imagery, GeoAI, and physics, not assumptions. When you can see the full picture clearly, you can act on it.” Read the full interview at the link in our bio.

The city of Copenhagen, Denmark, has made some of the world’s most significant strides in decarbonizing its building sector. 📉 Between 2019-2023 building-related emissions fell more than 60%. How? Large-scale electrification, renewable district heating, and efficiency upgrades, primarily. Climate TRACE estimates that these changes are resulting in emissions reductions of 110,000 tonnes of CO2e annually. If this approach is adopted globally, it could result in emissions reductions of 1.6 BtCO2e annually. Learn more about this emissions reducing solution (ERS) spotlight at the link in our bio.

These 10 countries had the highest absolute greenhouse gas emissions totals in 2025.

The world’s 2025 emissions broke the annual record, reaching a global total of 60.63 Bt CO2e. Despite a small decline in power sector emissions, fossil fuel operations, transportation, manufacturing, and buildings all nudged global greenhouse gas emissions higher.

2025 ANNUAL GLOBAL EMISSIONS DATA ARE NOW LIVE. Here are some of the highlights: 🌏 Global total: 60.63 Bt CO2e Global emissions have reached a new high. The record-setting annual emissions total for 2025 is 0.50% higher than the 2024 emissions total. 🐄 Methane emissions: 412.59 Mt CH4 in 2025 Global methane emissions rebounded, after a decline in 2024, increasing year over year by 1.03% and setting a new annual record. 🛢️Oil and gas production was the subsector with the largest jump in emissions, increasing 4.1% from 2024. 🇨🇳For the first time since 2015, China’s power sector emissions decreased year over year. 🇮🇳India’s power sector emissions fell for the first time since 2020. 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 Read the release for more of the key takeaways from 2025 emissions data at the link in our bio.

New York City, USA, and the surrounding area ranks #4 on our list of regions with the most people exposed to harmful PM2.5 air pollution from the combustion of fossil fuels. The air pollution visualised here is what we estimate exposure looks like on an average day, with emissions coming from 124 sources. Emitting facilities include power plants, heavy manufacturing sites, ports, mines, and refineries. 21 of these sources are considered to be super-emittors, meaning they are among the top 10% of emitters of PM2.5 pollution tracked by Climate TRACE worldwide. 16.7 million people are exposed to this regional pollution, which is known to cause premature death for millions of people annually.
