Nordic Ministers of Environment adopted in March 2012 the “Svalbard Declaration” with decisions to reduce the negative impacts of the climate changes and air pollution caused by the emission of the so-called Short-lived Climate Forcers (SLCFs) such as black carbon (soot) and methane. Along with CO2, they are the main reasons why the ice in the Arctic now is melting rapidly.  At a workshop organised by the Nordic Group on Climate and Air Quality in June 2012 researchers and policy-makers discussed the recent scientific findings, the national experiences with emission inventories, identification of cost-effective measures to cut emissions and the drawing up of national action plans as well as the development in the field of international co-operation on SLCFs. The report presents policy recommendations, conclusions and recommendations on scientific research and monitoring.

Danish emissions of particulates and black carbon – historical estimates and projections

The primary carbonaceous aerosols emitted as part of the total particles (TSP) during fuel combustion are classified into black carbon (BC) and organic carbon (OC). BC is the light-absorbing part of the particles (soot). It has global-warming properties due to its ability to absorb light over reflective surfaces, and due to its darkening effect when deposited on snow and ice surfaces. BC is regarded as a Short-lived Climate Forcer (SLCF). Seen from a global-warming perspective, the short-term benefits of reducing BC are promising.
