Government Advisors Urge Significant Airfare Hikes to Meet Net Zero Goals

Flights could become hundreds of pounds more expensive by 2050 as part of a strategy to decrease demand and meet Net Zero climate targets, government advisors have recommended. The Climate Change Committee (CCC) estimates that a family holiday to Alicante, Spain, could see a £150 increase in cost, while a round trip to New York could rise by £400.

These proposed cost increases are intended to be funded by the aviation industry, which would then pass the expenses on to consumers through ticket prices. The CCC suggests this approach would simultaneously reduce demand for air travel and generate revenue to invest in solutions for cutting emissions. The committee also warned that there is ‘no credible pathway’ to expanding Heathrow Airport without a reduction in emissions.

Policies such as employing more efficient aircraft, optimizing flight paths, and utilizing sustainable aviation fuels are necessary to achieve Net Zero, the CCC stated. The committee's report emphasizes that the costs associated with reducing the sector’s emissions impact, whether through direct reductions or carbon removal, should be borne by the aviation industry.

"We assume these costs will be passed on to consumers through ticket prices," the report notes. "This in turn will both reduce demand growth and generate revenues, so that the same policy instrument both reduces the size of the problem and serves to fund solutions."

The CCC found that while passengers believe airlines, rather than taxpayers, should bear the costs, they are hesitant about families being priced out of international travel. Potential measures include introducing a frequent flyer tax for individuals who take multiple flights annually, with an exemption for domestic UK flights.

Nigel Topping, Chairman of the CCC, highlighted that UK aviation emissions have doubled since 1990, contrasting with an overall halving of national climate pollution. He stated that Heathrow Airport is responsible for approximately half of the sector’s emissions and that by 2050, aviation emissions could overshadow those from all other economic sectors. He asserted that expansion at Heathrow alone could generate more emissions than any other sector.

"Ultimately, the polluter pays principle must apply," Topping said. "If aviation is to grow, it must take responsibility for the emissions it creates. Expansion can only be compatible with the UK’s climate commitments if the sector is required to manage and pay for the full cost of reaching net zero."

However, the airline industry has called for an affordable transition to Net Zero, pointing to existing investments in new aircraft, sustainable aviation fuel, and airspace upgrades totaling billions of pounds.

A spokesperson for the Department for Transport commented that any expansion proposal would need to align with net zero targets. The department is investing £219 million in sustainable aviation fuel production and an additional £43 million in cleaner technologies. The spokesperson also noted that airport expansion could contribute around £40 billion to the economy and support up to 60,000 local jobs. The department will consider the CCC's advice alongside responses to the Heathrow expansion consultation.
