Processing alternative proteins has a large impact on global warming, study finds
Meat grown in a lab could be 25 times more costly for the environment than beef, a study has found.
Cultivated meat is grown using animal cells, eliminating the need for rearing and slaughtering animals.
Its backers, including the Government, say it could also reduce the emissions from meat production, particularly methane from livestock, which accounts for around six per cent of global emissions.
