Last week, the Council of the International Civil Aviation Organization (ICAO), a permanent body comprised of thirty-six ICAO members, met in Montreal to discuss international aviation emissions. This meeting proceeded the September 24 – October 4, 2013 meeting of the full ICAO membership. The Council agreed to a temporary framework that would allow regional emissions trading systems to regulate portions of flights in their airspace.  In contrast to the European Union’s (EU) earlier attempt to regulate the full distance of all flights taking off or landing in the EU, this new agreement would allow regulation only of the flight portion in EU airspace. This agreement fell short of what many had hoped for – the adoption of a global, market-based system to reduce carbon emissions. The Council did agree, however, that such a comprehensive international plan would be secured by 2020. The agreement still must be approved by the full ICAO membership later this month at the Assembly.

In the end, the agreement is a compromise between the EU, which desires stronger emissions standards, and countries such as the United States and China, who have pushed to find a global solution. Hopefully, the Council’s decision will keep the peace until a global management plan is developed.
