Heathrow expansion's impact to airports around the UK

The Government has adopted the recommendations of its Climate Change Committee (CCC) on carbon targets and, as the Queen’s Speech confirmed on 11th May, these are to be enshrined into law. 


The Government committed to reducing carbon emissions by 78% (against 1990 levels) in advance of 2035; but it is demanding that, for the very first time, aviation emissions are included within targets for reductions. 

As the CCC stated, this means that there is no room for a net expansion of UK aviation; and that, were there to be an expansion of aviation at Heathrow, this would need to be offset by restrictions at regional airports (whether through reductions in operations or closures). 

Please see coverage of our letters to a large number of titles across the UK, below.


Heathrow Supreme Court Judgment 

In December 2020, the Supreme Court overturned the judgment of the Court of Appeal that the plan for Heathrow expansion was unlawful for having failed to take account of the Paris Agreement on climate change. Heathrow can now seek planning permission for the runway.

The full judgment can be found here and press summary here.

However, major obstacles remain including having to persuade a public inquiry of the case for expansion.

We've set out some of potential next steps in this document.

Heathrow airport is already the single largest emitter of carbon in the UK and a third runway would contribute an additional 6 million tonnes of carbon into the atmosphere every year.
