The aviation industry often argues that emissions from aviation are only around 2% of total carbon emissions.
These claims are misleading: they are based on out of date information; and they usually refer to a percentage of global emissions when a more relevant comparison would be with total UK emissions. None of them mention that aircraft emissions in the upper atmosphere are especially harmful. This briefing paper gives more realistic numbers, and explains why curbing emissions from aviation is vital if the UK is to meet its commitments on climate change. It concludes by examining air quality issues, and pointing out that the airport in its current form is already breaching EU air quality laws, a situation which expansion can only exacerbate.
