Richard Sulley, senior research fellow at the Grantham Centre, said: “When we are looking at investing public money, we really need to see published what else we could be doing with it. Is this the best thing to do with a significant amount of public investment?
“The committee on climate change, the independent body that advises government, says we should not have more airport expansion until there is a process in place to manage the number of flights that leave the UK.
“The authorities are stressing this will be about building sustainable aviation, but the technologies don’t exist yet so there will be a period where aviation fuel is being burned.
“Aviation has a disproportionate effect on the environment. It’s not just about carbon emissions, it is also about the contrails and the nitrous oxide that planes leave behind as they fly so it really is damaging to the environment.”
