This data-file breaks down global CO2 emissions into 40 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 deforestation, at 12% of the total, followed by passenger vehicles, also at 12%.
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.
The data-file contains our backup workings, and further data placing global CO2 emissions (in million tons per annum) in context with 25 other production industries globally.
