The controversial proposal to build a third runway at London’s Heathrow Airport has been thrust back into the spotlight, as Chancellor Rachel Reeves prepares to throw her full support behind the expansion. The move, part of a broader push to jumpstart the UK’s sluggish economic growth, has ignited fierce debate and exposed divisions within the Labour party.
Chancellor’s Growth Gambit Draws Backlash
Reeves, who has long backed the Heathrow expansion, is expected to give the green light not only to the third runway but also to increasing capacity at Gatwick and Luton airports. The chancellor argues that these infrastructure investments are vital to boosting trade, attracting businesses, and accelerating economic growth, which has languished at a meager 1.6% this year.
However, the plan has been met with swift condemnation from environmental activists and prominent Labour figures alike. Critics have labeled it a “desperate” attempt to prop up GDP growth at the expense of the UK’s climate commitments.
Labour Heavyweights Oppose Expansion
The most vocal opposition has come from within Reeves’ own party. Ed Miliband, the influential energy secretary tasked with keeping the UK on track to reach net zero emissions by 2050, is said to be vehemently against the airport expansion. London Mayor Sadiq Khan has also reiterated his longstanding objections, citing the negative impacts on air quality, noise pollution, and the capital’s decarbonization targets.
Resurrecting the idea of a third runway at Heathrow in the hope that a strip of tarmac will nudge up the UK’s GDP smacks of desperation. The economic benefits are dubious at best while the environmental costs in climate damage, noise and air pollution are certain.

Sustainable Fuel Mandate: Greenwashing or Genuine Offset?
Reeves has pointed to the government’s new sustainable aviation fuel (SAF) mandate as a means to offset the increased emissions from airport expansions. The policy requires airlines to use a small but growing percentage of greener fuels, starting at 2% by the end of 2025.
However, experts question whether this nascent technology can scale up quickly enough to meaningfully reduce the climate impact of an expanded Heathrow. The Climate Change Committee has previously warned that there should be no net airport expansion unless aviation emissions are outperforming the government’s reduction targets.
Political and Planning Hurdles Ahead
Even with Reeves’ backing, the Heathrow third runway faces a long and uncertain road. Heathrow has yet to submit a full planning application, and the proposals for Gatwick and Luton are still pending development consent from the transport secretary. Any expansion will have to demonstrate that it can drive economic growth while adhering to the UK’s environmental obligations – a challenging tightrope to walk.
As the battle lines are drawn, one thing is certain: the debate over Heathrow’s third runway is far from over. With the climate crisis looming and the economy sputtering, the UK faces difficult trade-offs in balancing short-term growth with long-term sustainability. How the government navigates this quandary may well determine the trajectory of both the country’s finances and its environment for decades to come.
