For electricity,
Location based method: In Japan, we use the actual emission factors announced by the Electric Power Council for a Low Carbon Society (ELCS) . Overseas, we use the factors according to country, as published by the International Energy Agency (IEA)
Market based method： We use the factors of each electric power company in principle, but if it is not available, use the emission factors based on location based method.
At the Kansai Office, we utilize CO2-free electricity through non-fossil fuel certificates supplied by the owner of the building.
