Our airports are national assets and their expansion is a core part of boosting our global connectivity. This in turn will drive economic growth for all parts of this country, connecting our nations and regions to international markets, levelling up our economy and supporting a truly Global Britain.

The Court of Appeal ruled on 27 February that when designating the Airports National Policy Statement, which was backed by Parliament, the previous Government did not take account of the Paris Agreement, non-CO2 emissions and emissions post 2050. We have always been clear that Heathrow expansion is a private sector project which must meet strict criteria on air quality, noise and climate change, as well as being privately financed, affordable, and delivered in the best interest of consumers. The Government has taken the decision not to appeal this judgment. The promoters of the scheme will be able to seek permission from the Supreme Court to appeal if they wish.

As part of its judgment, the Court has declared that the Airports National Policy Statement is of no legal effect unless and until the government carries out a review under the Planning Act 2008. The Court’s judgment is complex and requires careful consideration. We will set out our next steps in due course.
