Britain is keeping in place — and raising — its Air Passenger Duty, a per-passenger charge levied on airline itineraries originating in Britain. The government had promised to design a new charge based on aircraft; the current charge does not correlate actual emissions to charges for them. Two aircraft of identical capacity but with different fuel efficiencies are assessed the same amount of APD. Even worse, private aircraft, cargo aircraft, and transfer passengers (mostly at Heathrow) are exempt from APD, meaning that commercial travelers to destinations in Britain are bearing the brunt of aviation’s climate impact there. If Britain is serious about taxing its own travelers and airlines to mitigate climate change, then it needs to align charges with actual impacts.
