Members of Parliament voted, on 13 November, in favour of slightly toughening up a Commission plan to include the aviation sector in the EU's emission trading scheme, requesting the following changes:
- All airlines flying to and from EU territory should join the scheme in 2011. MEPs thereby rejected the Commission's proposal that international flights should be given an extra year and ignored threats from third countries, including the US, that they would instigate legal action if the EU attempts to unilaterally force them to comply with the scheme;
- airlines would be required to reduce emissions by 10% compared to average 2004-2006 levels, rather than just having to maintain those levels, as the Commission had initially proposed;
- 25% of the pollution permits would be auctioned out to airlines, rather than having at least 90% distributed to operators for free, as the Commission had originally suggested. Revenues from the sales would be used to mitigate greenhouse gas emissions, fund relevant research and "lower taxes and charges on climate-friendly transport such as rail and bus";
- the cost of all CO2 permits bought by airlines would be multiplied by two unless the Commission develops legislation to address additional climate impacts caused by Nitrogen Oxide (NOx) emissions from aircraft;
- an "efficiency clause" states that the aviation sector can only buy permits from other sectors if it first improves its own fuel efficiency, and;
- military flights and planes weighing less than 20,000kg, such as business jets, would be excluded.
