Definition of terms
GHG Greenhouse gases. There are six categories of greenhouse gases: carbon dioxide, methane, nitrous oxide, hydro fluorocarbons, per fluorocarbons and sulfur hexafluoride. Carbon dioxide itself can be divided into energy source and non-energy source types. Greenhouse gases other than energy-source carbon dioxide are known in Japan as the 5.5 gases. At Astellas, non-energy source CO2 was discharged from waste fluids from our incinerators before, but only energy-source CO2 is emitted now. In this report, GHG is used for all types of gas.
CO2 Abbreviation for carbon dioxide. In the Environmental Plan of Action, it is referred to as carbon dioxide.
Scope1 Volume of GHGs emitted directly from Company premises as a result of the burning of fuels (city gas, fuel oil, kerosene, diesel oil, gasoline, LPG, LNG)
Scope2 Volume of GHGs emitted indirectly in the use of electric power or heat supplied to the Company from outside
Scope3 GHGs emitted indirectly at some point on the Company's value chain (production, transportation, business trips, commuting, etc.)
SOx Sulfur oxides-emitted by the burning of fossil fuels containing sulfur
NOx Nitrogen oxides-formed through the combination of nitrogen and oxygen in the atmosphere during the combustion of substances
BOD Biochemical oxygen demand. Used as a benchmark for indicating extent of water pollution by organic matter in rivers.
COD Chemical oxygen demand-indicates the amount of water pollution due to the presence of organic compounds in seas or lakes
VOCs Volatile organic compounds-organic chemical compounds that are volatile in the atmosphere at standard ambient temperatures and pressures
