Estimated Black Carbon Emissions from Priority Source Categories in Russia

Black carbon is commonly considered as a short-lived climate forcer, the relatively short lifetime of which can cause climatic effects at the regional level. The lack of mandatory reporting on black carbon emissions and a unified methodology for black carbon inventory leads to high uncertainty of existing estimates of black carbon emissions in Russia. The estimates of emissions from priority source categories are provided in the present paper. According to the estimates, averaged black carbon emissions for the period of 2010-2020 from intentional fuel combustion at anthropogenic sources in Russia, including fuel combustion at energy and industrial enterprises, small and domestic combustion, transport, hydrocarbon flaring, are 100 x 10(3) t per year, and those from open combustion sources on non-forest lands are 10 x 10(3) t per year. Emissions from forest fires have the greatest interannual variability and vary from 100 x 10(3) to 300 x 10(3) t of black carbon per year.
