Should the government ban short-haul flights where a train alternative exists?

Short-haul flights are notoriously carbon-intensive per kilometer compared to train travel, often emitting ten times more CO2 per passenger. France recently enacted a ban on flights where a 2.5-hour train alternative exists, sparking a global debate about the future of travel. Proponents argue that in a climate emergency, eliminating unnecessary high-carbon travel is a crucial step toward Net Zero. Opponents argue that bans infringe on consumer freedom, ignore the unreliability of rail networks, and stifle aviation innovation.
