Farming and carbon emissions
Between 13% and 21% of all greenhouse gas emissions come from farming and related use of land. Raising animals for meat and diary products is particularly carbon intensive. Meat makes up approximately 5% of the food consumed by London households by mass, yet it's responsible for 27% of London's food-related consumption-based emissions. On the other hand, fruit and veg represent 21% of the food consumed by mass, yet are responsible for only 4% of consumption-based emissions.
It doesn't mean we have to stop eating meat altogether, but a few smart choices can cut the carbon footprint of our diet.
