Allocating international aviation CO2 emissions: the airspace-based approach and its alternatives

The ICAO Council established a High-level Group (HLG) last November to consider political questions relating to a global market-based measure (MBM) for international aviation and a Framework for MBMs. The Framework basis should harmonise state/regional MBM schemes that could build over time into a global scheme. Provisions for geographic scope in the Framework and global architecture should be consistent in order to avoid duplication. The Framework should presumably contribute towards a workable resolution of the dispute over the EU ETS. However, some states see the Framework as merely intended to ‘contain’ the EU ETS, in which case the two architectures – Framework and global – might not be compatible. So a key question for ICAO is how geographic scope is to be treated in the national/regional MBM Framework. However, argues Bill Hemmings (right), basing it on airspace – as becoming increasingly favoured by some major states – is unrealistic.
