This report designs policy instruments to reduce the climate impact from aviation NOx emissions.
In its feasibility study on the inclusion of aviation in the EU ETS, CE Delft argued that the non-CO2 climate impacts should be dealt with by ancillary policy instruments. As a result, the EU agreed to address NOx emissions in separate legislation. This report prepares for that legislation.
The main conclusions of this study are that:
There are two effective and cost-effective policy instruments to reduce the climate impact of aviation NOx emissions, viz.:
- An LTO NOx charge with a distance factor. or
- The inclusion of aviation NOx in the EU ETS, based on LTO NOx with a distance factor.
However, before either of these instruments can be implemented, two outstanding issues have to be resolved:
- A GWP for aviation NOx has to be established.
- The relationship between LTO and cruise emissions has to be established in a sufficiently robust way.
The report estimates that this can be done within three to five years, given sufficient study.
The report was prepared for the European Commission, DG Energy and Transport.
