Update:- LONDON HEATHROW EXPANSION 3rd RUNWAY = RUNAWAY CLIMATE BREAKDOWN
Hopefully this may enable you to make what sense can be made around Heathrow expansion?
As you know even before the intended £18billion further expansion, Heathrow is the UK's biggest emitter of Greenhouse Gases at a time of Climate Breakdown emergency.
Another runway would boost current flights of 480,000 to 740,000 seeing passengers rise to 132 million effectively creating a new airport the size of London Gatwick!
