Climate impact of Finnish air pollutants and greenhouse gases using multiple emission metrics
We present a case study where emission metric values from different studies are applied to estimate global and Arctic temperature impacts of emissions from a northern European country. This study assesses the climate impact of Finnish air pollutants and greenhouse gas emissions from 2000 to 2010, as...

We present a case study where emission metric values from different studies are applied to estimate global and Arctic temperature impacts of emissions from a northern European country. This study assesses the climate impact of Finnish air pollutants and greenhouse gas emissions from 2000 to 2010, as well as future emissions until 2030. We consider both emission pulses and emission scenarios. The pollutants included are SO 2 , NO x , NH 3 , non-methane volatile organic compound (NMVOC), black carbon (BC), organic carbon (OC), CO, CO 2 , CH 4 and N 2 O , and our study is the first one for Finland to include all of them in one coherent dataset.
