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.



Scientific developments regarding SLCFs

The two acronyms SLCFs (Short-lived Climate Forcers) and SLCPs (Short-lived Climate Pollutants) have been introduced in recent years to represent chemical components that have relatively short lifetime in the atmosphere – a few days to a few decades – and tend to have a warming influence on climate. The focus is on agents that are warming, but strictly speaking, short-lived components include also cooling agents. This distinction is important when discussing the influence on climate by aerosols, since they can have both warming and cooling effects depending on chemical composition, size, distribution and other factors. The change in wording from “forcers” to “pollutants” reflects the importance of stressing the co-benefits of reducing short-lived components that are both air pollutants and “climate pollutants”.
