Black carbon and methane in the Norwegian Barents region

In 2011, land based emissions of black carbon and methane in the Norwegian Barents region were 400 tons and 23 700 tons, respectively. The largest emissions of black carbon originate from the transport sector and wood combustion in residential heating. For methane, the largest contributors to emissions are the agricultural sector and landfills. Different measures to reduce emissions from black carbon and methane can be implemented. Retrofitting of diesel particulate filters on light and heavy vehicles, tractors and construction machines will reduce black carbon emitted from the transport sector. Measures to reduce black carbon from residential heating are to accelerate the introduction of wood stoves with cleaner burning, improve burning techniques and inspect and maintain the wood stoves that are already in use. In the agricultural sector, methane emissions from food production can be reduced by using manure or food waste as raw material to biogas production. If the population reduce their waste of food or eat less red meat, the methane emissions from food production will also be reduced. Reducing emissions of black carbon and methane (as a precursor for ozone) will in addition have positive effects on human health, especially in more densely populated areas.
