The average European and American causes 5.18 kg of CO2eq a day for his food consumption, or 150 000 kg CO2eq over his lifetime. With a climate-friendly diet, a person saves a total 100 000 kg CO2e - an impressive number. Amounting to the same amount of carbon as driving 15.5 times around the globe.
This is by far the biggest personal environmental impact YOU influence and YOU have direct control over (and no one else!).
