The expansion of high-speed, frequent rail and sea services will see a dramatic reduction in domestic and short-haul flights within the 'Island Britain' scenario. With few alternatives to conventional aviation fuel, air travel far from a zero-carbon technology. People will simply be travelling by less carbon-intensive transport. Train, ferry and coach fares would become cheaper, more frequent and more accessible.

In moving towards a zero-carbon economy there seem to be no easy fixes for international aviation. A number of airlines are currently researching synthetic fuels and hydrogen as a zero-carbon alternative to existing fuels. However, the latter still raises a secondary concern that high altitude flights would introduce water vapour to the atmosphere, a potent greenhouse gas at that level. Within the report's policy framework and 20 year zero-carbon target the challenge would lie with the aviation industry to innovate and develop a zero-carbon form of aviation.
