Regulation of climate gas emission from air transport

    It is well known that within the transport sector the aviation industry is facing serious challenges from the focus on climate gas emissions. Commercial flight stands for 2-3 per-cent of CO2-emissions, but has the highest expected growth rate within transport. At the same time alternative fuels and technologies with significant less climate impact seem to be far ahead (Lee et al. 2009, 2013).
    It is also well known that aviation, besides CO2, has significant green house gas-emissions (GHG-emissions) stemming from NOx’s and H2O emitted at high altitudes. The climate effect of these is very dependent on the concrete circumstances of the individual flight (Peeters and Williams 2009).
    The only regulation of climate gas emissions having been proposed is the inclusion of (European) aviation in the Emission Trading Scheme (ETS). This system only comprises CO2-emissions.
    This is not necessarily adequate. To ask the aviation industry for minimizing CO2-emissions is also to ask for lowered fuel consumption, which can be reached by increased flight altitudes, which in turn increases the climate effect of the other emissions from flight. The overall result is that we do not get the behavioral effect that minimizes air travels’ climate effect.
