Russia’s Black Carbon Emissions: The Arctic and Beyond Pacific Northwest National Laboratory has worked on BC emission study in Russia. The study consists of three part: BC diesel emission inventory for Murmansk, Russia-wide emission inventory from diesel sources and all-Russia inventory of BC emissions from all sources. The study estimates BC emissions from diesel sources in Murmansk Region and Murmansk City, the largest city in the world above the Arctic Circle. The study presents a detailed inventory of diesel sources including on-road vehicles, off-road transport (mining, locomotives, construction and agriculture), ships and diesel generators. The study presents a detailed inventory of Russian BC emissions from diesel sources. Drawing on a complete Russian vehicle registry with detailed information about vehicle types and emission standards, the study analyzes BC emissions from diesel on-road vehicles. Using Russian activity data and fuel-based emission factors, we also present BC emissions from diesel locomotives and ships, off-road engines. The study also factors in the role of superemitters in BC emissions from diesel on-road vehicles and off-road sources. Finally, the study estimates Russia-wide BC emissions from all sources. Using a wide variety of studies, we assess Russian BC emissions from wildfires, flaring, transportation, the domestic sector, power generation, heating and industry. Using satellite data, we estimate emissions from flaring, the second largest source of BC emissions after wildfires. We also present an adjusted estimate of Arctic forcing from Russian BC emissions.
