Government is counting on tech to provide a panacea, but there may be simpler ways to keep climate goals on track
Expanding Heathrow would result in increased carbon dioxide emissions and could put the UK further off track on its climate goals, but the government is claiming it can offset that by investing in research on new low-carbon fuels for aircraft and on electric planes.
However, any such technology is still decades away, if it ever reaches commercial scale, making it certain that any new runway in the near future would be used by the same kerosene-fuelled, high-carbon aircraft that we have today.
