The recent legal clearance for Gatwick Airport to proceed with a second runway has reignited a debate regarding the role of aviation in the UK economy and its environmental footprint. Proponents of airport expansion generally argue that such projects are essential for infrastructure growth, international connectivity, and regional economic development.

Conversely, environmental advocates contend that the expansion is fundamentally incompatible with climate change targets. A central point of contention is the economic classification of the aviation sector. While industry representatives often frame aviation as a critical driver of trade and business, critics argue that the sector is primarily a leisure industry. These critics suggest that the industry’s narrative of 'business as usual' ignores the reality of rising planet-heating emissions. The disagreement centers on whether the economic benefits of increased flight capacity outweigh the long-term environmental costs, with critics asserting that the industry is not as vital to the UK's financial stability as its lobbyists claim.
