Directive 2008/101/EC states that revenues generated from the auctioning of allowances for aviation should be used to tackle climate change. The application of this provision by the EFTA States is without prejudice to the scope of the EEA Agreement. As regards the decisions on benchmarks pursuant to Articles 3e(3) and 3f(5) of Directive 2003/87/EC as amended by Directive 2008/101/EC, the Contracting Parties will make every effort in order to ensure swift adoption and entry into force of any EEA Joint Committee decisions incorporating each decision of the European Commission. In order to guarantee the homogeneity of the EEA and of its common ETS, a joint and parallel process of the Contracting Parties shall lead up to the decisions of the European Commission, which shall be incorporated into the EEA Agreement, if necessary by use of written procedure. With the aim to provide for a transparent ETS in the EEA for all aviation operators concerned, the European Commission will include special clauses in its decisions implementing Directive 2008/101/EC, which will make reference to the extension of the decisions to the EEA EFTA States by decisions of the EEA Joint Committee. .
