U.S. household food purchasing is a major source of greenhouse gas emissions – about 16% of total U.S. emissions in 2013. Households with higher incomes contributed the most to greenhouse gas emissions. This report is summarized on the site of the Leonardo DiCaprio Foundation and published in the Journal of Food Policy in August 2018.
Actions you could take to help reduce greenhouse gas emissions: eat a little less meat, eat food grown closer to home, waste less food.
