No carbon saved by diverting Heathrow passengers to Bristol
who currently fly from Heathrow and other South East airports and save carbon
emissions has been dismantled in a new report released today.

"Bristol airport has always claimed that their expansion will be able to divert
most of this ‘leakage’ back from Heathrow and other airports and will ‘save’ greenhouse
gas emissions on car journeys – but a close look at the facts shows this assumption
simply doesn’t hold up.

impact on the leakage and would significantly increase emissions.
