About Carbon Majors

Carbon Majors is a database of historic production data from 141 of the world’s largest oil, gas, coal, and cement producers. This data is used to quantify the direct operational emissions (Scope 1) and emissions from the combustion of marketed products (Scope 3) that can be attributed to these entities. These entities include:

94 Invester-owned Companies, 39 State-owned Companies, 8 Nation States,

85 Oil Producing Entities, 84 Gas Entities, 64 Coal Entities, 7 Cement Entities

The data spans back to 1854 and contains over 1.42 trillion tonnes of CO2e covering 72% of anthropogenic emissions since the start of the Industrial Revolution.

Carbon Majors & Anthropogenic Industrial CO2 Emissions, 1854 - 2023

This graph shows the carbon dioxide emissions traced to the carbon fuels and cement produced by the Carbon Majors entities and compares them to global emissions of carbon dioxide from all anthropogenic industrial sources.
