What you should know about this indicator

This data is based on territorial emissions, meaning the emissions produced within a country's borders, but not those from imported goods. For example, emissions from imported steel are counted in the country where the steel is produced. To learn more and look at emissions adjusted for trade, read our article: How do CO₂ emissions compare when we adjust for trade?

Emissions from international aviation and shipping are not included in the data for any individual country or region. They are only counted in the global total.

Share of global CO₂ emissions

Annual total emissions of carbon dioxide (CO₂), excluding land-use change, measured as a percentage of global emissions of CO₂ in the same year.

Sources and processing<br>This data is based on the following sources<br>Global Carbon Project – Global Carbon Budget

The Global Carbon Budget was established by the Global Carbon Project (GCP) to track global carbon emissions and sinks.

This dataset makes it possible to assess whether countries are making progress toward the goals of the Paris Agreement and is widely recognized as the most comprehensive report of its kind.

Since 2001, the GCP has published estimates of global and national fossil CO₂ emissions. Initially, these were simple republished data from other sources, but over time, refinements were made based on feedback and correction of inaccuracies.
