The Climate Change Committee has stated that the proposed third runway at Heathrow cannot proceed without significant changes to current climate policies. They emphasize that the aviation sector must fund cleaner fuels and carbon removal technologies to align with the UK's Net Zero targets.
The expansion project, estimated at £33 billion, aims to increase passenger capacity significantly. However, the committee warns that without the aviation industry bearing the costs of decarbonization, the expansion remains incompatible with climate goals, raising concerns about its environmental impact.
