British Airways embarks on domestic flight offset programme

BA chairman and chief executive Alex Crus said: "Solving the complex issue of climate change requires a multi-faceted response, and offsetting emissions on all flights within the UK is just one step we are adopting to reduce our environmental impact while more solutions to decarbonise are found.

"Our emissions reductions projects are carefully chosen to ensure they are proven and deliver real carbon emissions reductions as well as economic, social and environmental benefits."

Cruz added BA was investing in aircraft offering 25% to 40% better fuel efficiency than those they replace.

Customers flying further afield can calculate the likely emissions impact and offset them through BA’s partnership with not-for-profit Pure Leapfrog.

Offsetting starts from around £1 on a return London-Madrid flight, and £15 for a business class London-New York flight.
