Air travel costs are set to rise dramatically by 2050

In the UK, the Climate Change Committee has issued a stern warning regarding the aviation industry's responsibility in reducing greenhouse gas emissions. In its latest recommendations, the committee emphasized the need for the government to implement significant measures to curb aviation emissions, which aim for a reduction of 17 percent by 2050 compared to 2023 levels. This aligns with the broader goal of achieving an overall 87 percent reduction from 1990 emission levels by 2040. The committee's advice comes amid discussions concerning the potential expansion of major airports, including Gatwick, Luton, and Heathrow. These expansions, the committee asserts, must be balanced with environmental responsibilities to ensure that air travel does not undermine the UK’s climate targets. Suggested measures to manage increasing demand include hiking air passenger duty and establishing a frequent flyer levy, both of which have received some backing from citizens' panels. In terms of direct impact on air travel costs, it is projected that a return ticket to popular destinations like Alicante, Spain, could rise by approximately £150, while a round-trip ticket to New York could see an increase of around £300 by 2050. The committee expects that technology advancements in sustainable aviation fuel and more efficient aircraft will contribute positively to reducing overall emissions. However, environmental advocates have criticized the government's focus on developing sustainable aviation fuel as overly optimistic and incompatible with climate targets. The committee has suggested that if the aviation industry fails to invest adequately in alternative technologies, stricter policies may be necessary, including limitations on airport capacity. The urgency of these recommendations is underscored by upcoming decisions regarding airport expansion plans, with deadlines set for determining the approval of these projects.
