The aim of this report is to give input to Finnish greenhouse gas (GHG) inventory of energy (stationary combustion) and industrial sectors. In this study, the non-CO2 emission factors (mainly CH4 and N2O; at a lesser extent, CO and NMVOC) for combustion and industrial processes used in the Finnish GHG inventory are evaluated based on domestic and international literature, available measurement data and expert interviews. Results of this study revealed many potential areas for improvements in the inventory. Consequently, recommendations to update the CH4 and N2O emission factors from boilers and industrial processes are given, including guidance on the level of the calculations.
