Explore updated data on greenhouse gas emissions and their climate impacts

To limit and stop climate change, we need to greatly reduce global emissions of greenhouse gases (GHGs).

Our CO₂ and Greenhouse Gas Emissions Data Explorer lets you track how emissions are changing country by country, and also understand their impacts on the climate.

I recently updated our charts with data on GHG emissions from the publication Jones et al. (2025), which in turn relies on data from the Global Carbon Project (GCP) and PRIMAP-hist.

Contribution to global mean surface temperature rise, 1851 to 2024.

Line chart showing each country’s cumulative contribution to global mean surface temperature change from 1851 to 2024, calculated from emissions of three gases: carbon dioxide, methane, and nitrous oxide. X-axis covers years 1851 to 2024; Y-axis shows contribution in degrees Celsius from 0 to about 0.3 °C.

Key points: United States contributes the most, rising steadily to about 0.3 °C by 2024. China’s contribution increases rapidly from around 1980 to about 0.2 to 0.22 °C by 2024, making it the second largest. Russia is next at roughly 0.1 to 0.12 °C. Brazil, India, Indonesia, Germany, and the United Kingdom each contribute smaller amounts, roughly in the range of 0.04 to 0.09 °C by 2024. These are the top 8 contributing countries.
