For reporting our greenhouse gas emissions we are referring to the Greenhouse Gas (GHG) Protocol. This includes direct CO2 emissions (Scope 1 emissions) from energy generations and production, and indirect CO2 emissions (Scope 2 emissions) from purchased energy. Together with other greenhouse gases, the total is expressed in CO2 equivalents.
Scope 2 emissions calculated using the location-based method include regional emissions factors. For the majority of our sites around the world we calculate our emissions using the market-based method. In 2018, the market-based method covered 94 percent of our power-related scope 2 emissions and 80 percent of steam emissions.
