Understanding causes and impacts of greenhouse gas emissions from food and agriculture can help you make choices to protect the environment. And what’s better for the environment is often better for your own health. Red meat and dairy are responsible for nearly half of all greenhouse gas emissions from food for an average U.S. household.
• Almost 1/3 of world human-caused GHGs are estimated to come from agriculture and forestry.
• Livestock production alone is responsible for an estimated 18% of world GHGs, more than the contribution of transportation, according to the U.N. Food and Agriculture Organization.
