European Union (EU) negotiators are clashing with member states on whether to require all airlines using EU airports to pay for their emissions. Currently, only emissions from intra-EU flights are regulated; last Thursday, however, members of the European parliament’s environment committee voted to charge for emissions for all flights through European airspace. The proposed rules were met with opposition from EU member states including Great Britain, France, and Germany, who want the EU’s Emissions Trading System confined to intra-EU flights in order to avoid angering trading partners. Low-cost airlines that fly primarily within Europe, however, support the legislation. They feel that being required to pay for emissions—while major international airlines are not—puts them at a competitive disadvantage. If an agreement is not reached by April, previous legislation that would charge all flights in and out of EU airports for emissions over their entire journeys would automatically apply. For the full story, see http://uk.reuters.com/article/2014/01/30/us-eu-carbon-aviation-idUKBREA0T0Y820140130 and http://www.euractiv.com/transport/parliament-defies-european-counc-news-533156.
