The only way the UK could have another runway without breaking climate change laws would be to increase prices
When the government’s Airports Commission endorsed the expansion of Heathrow last year it was challenged to explain how the UK could expand its airports without breaking climate change laws that limit greenhouse gas emissions.
It was a reasonable question. Like most countries, the UK has a tough emissions target for 2050 and, even though aviation has been given an easy ride compared with other industries, the sector is on course to exceed its generous limit. That’s the case even without adding a new runway. Increasing the number of flights from the UK would put the target further out of reach.
