The expansion of Heathrow would be an expensive disaster for Britain and the world. Burnham needs to block it | George Monbiot

A lengthy commentary by George Monbiot argues that building a third runway at London Heathrow would be an economic and climate disaster for Britain and the wider world. Using figures attributed to the UK Department for Transport, the article cites a projected cost ranging from £23.4bn to £62.5bn and says the real GDP boost is far smaller than claimed: 0.03% to 0.05% versus a previously stated 0.43%. It says the project would worsen health and wellbeing for up to 3 million local people and create major global climate costs. The piece also notes delays and targets, including a now-estimated completion year of 2039, and argues that aviation emissions are set to dominate by 2050.
