Under the UNFCCC, the EU and its Member States have taken a joint emission reduction target to reduce its GHG emissions by at least 20 % compared to 1990 by 2020, with a conditional offer to move to a 30% reduction, provided that other developed countries commit themselves to comparable emission reductions and developing countries contribute adequately according to their responsibilities and respective capabilities. This is documented in the UNFCCC revised notes on the "Compilation of economy-wide emission reduction targets to be implemented by Parties included in Annex I to the Convention"?
