(15)In line with the Council's conclusions of 9 March 2012 and the offer of the Union and its Member States to take on an 80 % target under the second commitment period, the emission levels of the Member States are equal to the sum of the annual emission allocations for the period 2013-2020 determined pursuant to Decision No 406/2009/EC of the European Parliament and of the Councilnote. That amount, based on global warming potential values from the Fourth Assessment Report of the Intergovernmental Panel on Climate Change, was determined under Annex II to Commission Decision 2013/162/EUnote and adjusted by Commission Implementing Decision 2013/634/EUnote. The emission level for Iceland was determined in the Agreement with Iceland.
