Heathrow expansion cannot go ahead without cutting flying emissions, say climate advisers

The Climate Change Committee warns that Heathrow expansion is incompatible with climate goals unless flying emissions are significantly reduced. Advisers state a new runway could emit CO₂ equivalent to the city of Birmingham. To fund necessary mitigation measures, the cost of international flights might increase by hundreds of pounds by 2050. Consequently, the independent body asserts that the proposed expansion cannot proceed without a concrete plan to cut emissions and align with national environmental targets.
