CEO Willie Walsh said its company would also cut emissions with sustainable practices and new technologies . Offsetting has been criticised as a get - out clause for polluting businesses , but Walsh said there was currently no credible alternative to using carbon - based fuel . He also said the scheme would invest in regulated and verified carbon reduction projects and that BA ’s heaviest fuel users , its Boeing 747s , would be withdrawn after 2024 . IAG airlines generate about 3 % of aviation emissions .
