A measure of annual emissions of carbon dioxide (CO2), one of the six Kyoto greenhouse gases (GHG), from electricity and heat generation (subsector of the energy sector) including IPCC 2006 code 1.A.1.a. The measure is standardized to carbon dioxide equivalent values using the Global Warming Potential (GWP) factors of IPCC's 5th Assessment Report (AR5).
