About this data

Indicator: Carbon dioxide (CO2) emissions (total) excluding LULUCF (Mt CO2e)
Unit: Mt CO2e

A measure of annual emissions of carbon dioxide (CO2), one of the six Kyoto greenhouse gases (GHG), from the agriculture, energy, waste, and industrial sectors, excluding LULUCF. The measure is standardized to carbon dioxide equivalent values using the Global Warming Potential (GWP) factors of IPCC's 5th Assessment Report (AR5).
