Going vegan: can switching to a plant-based diet really save the planet?

If politicians are serious about change, they need to incentivise it, say scientists and writers

The UK business secretary, Kwasi Kwarteng, is considering a full vegan diet" to help tackle climate change, saying people will need to make lifestyle changes if the government is to meet its new emissions target of a 78% reduction on 1990 levels by 2035.

But how much difference would it make if everyone turned to a plant-based diet? Experts say changing the way we eat is necessary for the future of the planet but that government policy is needed alongside this. If politicians are serious about wanting dietary changes, they also need to incentivise it, scientists and writers add.
