GHG Protocol Scope 1 - direct emissions from sources owned or controlled by the company. 4 SUB-CATEGORIES: (1) STATIONARY COMBUSTION - emissions from combustion of fuels in stationary equipment including boilers + furnaces + burners + turbines + heaters + incinerators + engines + flares + ovens + dryers + and other stationary processes; FUELS include natural gas + coal + oil + biomass + biofuels + waste-derived fuels + hydrogen; CALCULATION via fuel consumption x emission factor (IPCC + national + manufacturer + EPA Mandatory Reporting Rule + EEA + others); (2) MOBILE COMBUSTION - emissions from transportation in mobile sources including company-owned/controlled vehicles + trucks + ships + planes + trains + machinery; FUELS include gasoline + diesel + jet kerosene + biofuels + LPG + CNG + LNG + hydrogen; CALCULATION via fuel-based or distance-based methods; (3) PROCESS EMISSIONS - emissions from physical or chemical processes including cement production + iron + steel + ammonia + chemical processes + refrigeration + waste treatment + landfill methane + manure management; CALCULATION via mass-balance + process-specific emission factors; (4) FUGITIVE EMISSIONS - emissions from unintentional releases including refrigerant leaks (HFCs + CFCs + HCFCs + PFCs + SF6 + NF3) + methane leaks (natural gas systems + agriculture) + air conditioning + fire-suppression; CALCULATION via direct measurement + emission factors + leak rates. GHG GASES (Kyoto basket + others): CO2 + CH4 + N2O + HFCs + PFCs + SF6 + NF3; expressed in tCO2e using GWP (Global Warming Potential) from IPCC AR5 (most recent + with AR6 update pipeline).
