Heathrow expansion

Help stop Heathrow expansion

Back in February, with your support, we scored a huge victory for the planet when the Court of Appeal agreed that plans to build a third runway at Heathrow were illegal.

But in December 2020, the Supreme Court overturned the decision, allowing the project to proceed to the next stage.

The Supreme Court judgment is by no means a "green light". Boris Johnson has the power to scrap the policy decision to support Heathrow expansion. If enough of us speak out, Heathrow's third runway can still be stopped.

Short-lived victory in Court of Appeal

In February 2020, the government’s decision to expand Heathrow Airport was ruled "unlawful" by the Court of Appeal on climate grounds.

At a time when the government should be investing in sustainable transport to address the climate emergency, it was a massive win for our local groups, our legal team, and all our supporters.

Then in December 2020, the Supreme Court overturned the ruling. Despite the disappointing news, a third runway is not a done deal... yet.

Why Heathrow expansion is a bad idea

1) We can't stop climate breakdown by building runways

Heathrow is already the biggest single source of greenhouse gases in the UK. A third runway will all but blow our chances of meeting our targets for cutting emissions.

2) More flights for the few

Just 15% of the UK’s population take the majority (70%) of all flights. A bigger airport would mainly serve the interests of frequent flyers.

3) Filthy air, more noise

Already local people have to endure 1,300 noisy planes landing and taking off at Heathrow every day. Air pollution locally is way above legal limits.

4) The economic argument doesn't stack up

The government claims a third runway will be good for the economy – but there are no guarantees. And they haven’t factored in the true costs of climate change.

5) Transport on the wrong track

A bigger climate-wrecking airport is a massive distraction. 

We urgently need to invest in our rail and public transport networks – they’re simply not good enough for 21st century Britain.
