Britain will not be able to meet its goals on climate change without curbing the demand for air travel, according to an Oxford University report.
The government is targeting a 60% cut in carbon dioxide emissions by 2050.
But the report authors say the UK is becoming “air dependent” and government policies on increasing air travel contradict that stated aim.
The government said it wanted aviation included in the next round of the EU Emissions Trading Scheme.
Carbon dioxide emissions from aviation doubled during the 1990s while those from the rest of the economy fell.
