Emission Scenarios for Non-CO2 Greenhouse Gases in the EU-27--Mitigation Potentials and Costs in 2020

To provide quantitative information for the debate on the burden sharing of the European Union target to reduce greenhouse gas (GHG) emissions in 2020 by 20 per cent, this report assesses the potential and costs for further mitigation of the non-carbon-dioxide (CO2) GHG emissions beyond the currently agreed policies. It addresses the non-CO2 gases included in the Kyoto protocol [i.e., methane (CH4); nitrous oxide (N2O); and the three F-gases: hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6). This study employs the GAINS (Greenhouse and Air pollution Interactions and Synergies) model to project future emissions and to assess the remaining mitigation potentials and costs.
