Change in global mean surface temperature caused by greenhouse gas emissions

This dataset quantifies the change in global mean surface temperature (GMST), in degrees Celsius, that can be attributed to cumulative greenhouse gas emissions (CO₂, CH₄, N₂O) from each economy, from 1851 to the most recent year. It estimates how each country’s historical contribution to atmospheric CO₂-equivalent emissions drives warming, using global warming potentials (GWP*) and the transient climate response to cumulative emissions (TCRE) approach. The warming impact is calculated based on national emissions data aggregated across fossil and land-use sources and converted to a temperature change index, showing the contribution to global climate change over time.
