Recommendation 22

Zero-emission flight is sometimes described as providing ‘guilt-free’ flying. While it is the case that ZEF technologies remove the CO2 emissions from conventional aircraft movements which are aviation’s most damaging effect on the environment, the potential effects on the atmosphere from both hydrogen and battery-electric flight are not fully known. We recommend that the Government, when promoting research into the non-CO2 effects of aviation, include in its strategy the funding of research into the effects on the atmosphere and climate of aircraft using zero-emission flight technologies.
