On April 16, the European Parliament approved a proposal to delay the introduction of international airline’s into the Emissions Trading System (ETS) by a vote of 577-114 with 21 abstaining. The proposal, an informal agreement made by EU members back in March, was designed to let the International Civil Aviation Organization (ICAO) host internal discussions on greenhouse gas reduction mechanisms. According to a 2008 law, airlines had to submit 2012 emissions and permits by the end of April 2013; the deferral means airlines must submit 2013 data by the end of April 2014. Flights within the EU, however, must hand in allowances for 2012 emissions by April 30.
