The International Air Transport Association, IATA, states that biofuels offer the greatest hope for aviation to reach carbon emissions targets and that government support for the industry could be crucial. An E4tech report for the UK Committee on Climate Change in 2009 identified a significant potential for use of sustainable biofuels in aviation if technologies continue to be developed. E4tech’s estimate for the penetration of biofuels in the aviation fuel mix in 2050 is as high as 85% - given favourable conditions.

The agreements reached at COP16 in Cancun 2010 call for countries to join the UNFCCC’s effort to cut global emissions by half by 2050. Christiana Figueres, Executive Secretary of the UNFCCC, said that the Cancun Agreement “needs to be implemented as fast as possible”. E4tech supports this objective, but we also recognise that achieving it will be hard. In the meantime, low carbon innovation must continue. Whether it is by unilateral, bilateral or multilateral means, the need is the same – to make the most efficient, fair and low impact use of the energy resources available to us, whilst capturing economic benefits.
