Breakdown of global CO2 emissions

This data-file breaks down global CO2 emissions into 35 distinct categories, based on prior publications, our own models and calculations.

The long tail illustrates the complexity of decarbonisation. The largest single component of global emissions is passenger vehicles, but this comprises just c14% of the total CO2e.

A further 30 line-items all account for at least 1% of the world’s total emissions including electricity, heating, cement, metals, plastics, food, fertilizers, paper, manufacturing, livestock, agriculture, military, oil refining, fossil fuel production and landfill.
