Russia is the world’s largest exporter of oil and gas combined and the fourth biggest CO2 emitter, so it’s efforts in mitigating CO2 emissions are globally significant in curbing climate change. However, the existing emission inventories only present national CO2 emissions; the subnational emission details are missing. In addition, the emission factors are not country-specific and energy activity data by fossil energy types and sectors are not sufficiently detailed. Since existing emission inventories of Russia do not provide detailed emissions by energy types and socio-economic sectors, a further comparison of the emissions by energy types and by socio-economic sectors cannot be made. Overall, Russia’s energy structure is relatively stable from 2005 to 2019.
