UK airports say they can reach net zero and still expand. Is it just pie in the sky?

The Guardian - Despite the Climate Change Committee's warnings to stop growing capacity, Gatwick is gearing up for another try at a second runway. So what bit of no new airport capacity did airports not understand? The Climate Change Committee (CCC) spelled it out again on Wednesday: flying accounted for 7 of UK carbon emissions last year, the trend is upwards, and more airport capacity is incompatible with national net zero targets.Of course, they've said it before: but as the committee noted in its 2023 progress report, airports have since have been racing to expand.
