Global Food-Miles Account for Nearly 20% of Total Food-Systems Emissions
Global “food miles” emissions are higher than previously thought – accounting for nearly one-fifth of total food-system emissions.
The study, published in Nature Food, estimates the carbon footprint of the global food transport system. The authors assess the entire food supply chain – considering emissions from transporting fertilisers, machinery and animal feed as well as from moving the food itself.
They find that in a single year, global food miles were responsible for 3bn tonnes of CO2 equivalent emissions – 3.5-7.5 times larger than previous estimates.
