0kg is below the US average dietary carbon footprint of 1750kg and below the 680kg upper limit of a sustainable diet.
For your reference, 0kg of Carbon is equivalent to 0 gallons of gasoline burned and 0 cubic feet of ice melted every year.
Looking for ways to improve your diet's sustainability? Meat and dairy production account for three-fourths of all carbon emissions from an average American diet and are also the two highest sources of water usage in food production.6,1 For a seven day meal plan with recipes and tons of other good stuff, check out these recommendations from the Harvard T.H. Chan School of Public Health on consuming a healthy and Earth-friendly diet.
