title: Climate TRACE Emissions Inventory

description: Climate TRACE is a non-profit coalition of organizations building a timely, open, and accessible inventory of exactly where greenhouse gas emissions are coming from. Climate TRACE estimates greenhouse gas (GHG) and air pollutant emissions for over 1.8 million sources (from over 660 million assets), and every single country globally.

Each download package includes CSVs of:



Annual country-level emissions by sub-sector and by gas beginning in 2015

Monthly source-level emissions by sub-sector and gas beginning in 2021 and confidence

Emissions source ownership where and when available.


All Climate TRACE data are free and publicly available under a CC-BY 4.0 license to enable action and accountability at the massive scale necessary for global progress. Beginning in March 2025, Climate TRACE is releasing updated data with a 60-day lag during the final week of each month. All previous versions of the Climate TRACE asset- and country-level database will be uploaded to this page.

With the addition of April 2025 data, the Climate TRACE database is now updated to version 4.4.0.

Version 4.3.1 (released in June 5, 2025) will be available here. In this version, the database was updated to add 2024 rice cultivation data for 19 countries in Asia; added historic data covering synthetic fertilizer application emissions from 2015 through 2021; added Q1 2025 data for water reservoirs; added oil and gas refining data covering July 2024 through September 2024, adjusted refinery types on 7 US refineries and one additional refinery that is in the process of converting into a biorefinery; added February 2025 data for aluminum, steel, and cement manufacturing; added Q2 2024 data for petrochemical sources in Asia-Pacific and the Middle East and Q3 2024 data for sources in North America and Europe; updated asset-level power plant data to reflect new research on unit attributes; added 79 airports with domestic aviation emissions and 15 airports with international aviation emissions, added monthly aviation data covering emissions from 2015-2022, updated fuel burn estimates for certain aircraft types, and fixed issues with airline operation percentages at certain airports; updated road transportation data covering July 2024 through February 2025; and added February 2025 wastewater treatment and discharge emissions data. In addition, Climate TRACE updated the formatting of its ownership information for greater clarity and ease of use. Additionally, the v4.3.1 update corrected a bug in city-level road transportation emissions data and added ownership data for petrochemical assets. A detailed description of all data updates is available here.

We recommend getting familiar with how Climate TRACE data are created and structured by reviewing our FAQs, resources, and guidance:



The Climate TRACE FAQs page is an especially useful resource to quickly learn how we develop the emissions inventory, what data are contained in the inventory, details on units of measurement and coverage, and much more.

The Sectors page summarizes methodological details on dozens of sub-sectors. The data are licensed under the Creative Commons Attribution 4.0 International License; more details can be found on our terms of use page.

Detailed guidance on the data schema, licensing, and citations can be found in the data guide, as well as in the “detailed-data-schema” in the download packages.
