The European Union's climate action commissioner has challenged those countries opposed to the EU Emissions Trading System (EU ETS) to come up with a "constructive proposal" for a global alternative.
Connie Hedegaard spoke out on Twitter today ahead of a scheduled meeting between 26 nations, including China, Russia, India and the USA, in Moscow tomorrow, at which they are expected to discuss taking joint retaliatory action against the EU ETS.
Opponents of the scheme, which requires all carriers to pay for their carbon dioxide emissions on flights to and from EU member states, argue that it creates competitive distortion. Many have called for it to be suspended while the International Civil Aviation Organisation (ICAO) works on producing a global regulatory framework.
Hedegaard responded today: "Question to countries meeting in Moscow: we know what you don't like, but what's your constructive proposal for a global agreement on aviation?"
