Greenhouse Gas Emissions By Human Activity

Climate Watch Historical Emissions data contains sector-level greenhouse gas (GHG) emissions, including emissions of the six major GHGs from most major sources and sinks. Non-CO₂ emissions are expressed in CO₂ equivalents using 100-year global warming potential values from the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report (AR5).

More information about their data sources and methodology can be found in their FAQ page. Specifically, the definitions of all Climate Watch data sectors and their methodology are explained in this document.
