The aim of this study was to develop as complete an inventory of Sweden's BC emissions as possible based on the existing PM_2.5 inventory and information available in the EMEP/EEA guidebook 2013.

The Swedish BC inventory has been based on the submission 2014 PM_2.5 inventory together with BC emission factors expressed as percentages of the PM_2.5emissions, as available in the EMEP/EEA air pollutant emission inventory guidebook 2013.

The result of the Swedish BC inventory shows that the total emission of BC in Sweden was nearly 4.2 ktonnes in 2012 and that approximately 95% of BC emissions originated from the energy sector. The predominant source within the energy sector is small scale combustion, i.e. residential biomass combustion. Other important sources are stationary combustion in pulp, paper and print industries, off-road vehicles and other machinery, and road traffic.
