Annex - Methodology to calculate GHG emissions (1) 2 - IE, electricity used Step 1. Calculation of emissions Activity data
Electricity consumption (GWh) Emission factor for electricity (ton/GWh)
Step 2. Calculation of total emissions of CO2e in kg
Emissions calculated per GHG and converted to CO2e multiplying by GWP
EF are country & year specific
