Heathrow Expansion Faces Climate Hurdles, Advisers Say
Government advisors state that Heathrow's third runway cannot proceed without significant changes to climate policies, potentially increasing flight costs.
Heathrow's proposed third runway cannot be approved under the UK's current climate policies, government advisors have stated. The Climate Change Committee (CCC) advised that the expansion could proceed only if the aviation industry funds cleaner fuels and carbon removal technologies.
Such measures could lead to increased airfares, with a round trip to Alicante potentially costing around £150 more by 2050 and a journey to New York rising by approximately £400 in today's prices. The CCC projects that once operational, the expanded Heathrow would generate more carbon dioxide annually than any other single sector of the economy by 2050.
"Our advice today is clear - Heathrow expansion is not currently compatible with the UK's Net Zero target," said Nigel Topping, the CCC chair. "Government needs to ensure that the aviation industry takes responsibility for the emissions it creates and bears the costs of decarbonisation. Those conditions do not exist today."
The CCC's report does not have the power to block the runway but urges the government to implement legislation that places the long-term responsibility for aviation's decarbonization on the industry itself. The Department for Transport (DfT) stated that the government will "carefully consider" this advice along with other responses to its ongoing consultation, which is evaluating the expansion against criteria for the economy, climate, air quality, and noise.
The £33 billion project aims to increase Heathrow's passenger capacity from 85 million to 150 million per year. A DfT spokesperson noted that any expansion must align with the country's climate targets, while also highlighting the potential economic benefits, including an estimated £40 billion boost to the economy and support for up to 60,000 local jobs.
Some researchers have expressed skepticism that the CCC's recommendations will be sufficient to achieve the required reduction in greenhouse gas emissions. Dr. Lois Pennington of the Tyndall Centre for Climate Change Research suggested that due to the uncertain scalability of cleaner fuels and carbon removal, the most reliable method to remain within carbon limits would be to halt or even reduce air travel.
Despite the CCC's advice, government ministers have indicated a strong intention to proceed with the expansion. Chancellor John Healey recently stated that the project has been given the go-ahead because "the economic case stacks up and will help bring growth."
A formal vote in the House of Commons is expected later this year to approve the planning framework for the expansion. Prime Minister Andy Burnham has previously opposed the third runway, arguing it could divert investment from northern regions to London and the Southeast. The Mayor of London, Lord Sadiq Khan, has also voiced concerns regarding the project's climate and noise impacts. The expansion plan faces opposition from residents and local councils in areas under proposed flight paths, with approximately 750 homes slated for demolition due to long-standing issues of noise and air pollution.
