A new study from Tufts University provides the latest and most comprehensive estimate of greenhouse gas emissions generated by US consumer food purchases, and assesses how those choices could affect diet and climate change.
The study suggests that, if Americans directed their food purchases away from meats and other animal proteins, they could help reduce greenhouse gas emissions.
It goes on to say that altering food consumption could be a key area for reducing greenhouse gas emissions, as food purchases accounted for 16 percent of U.S. greenhouse gas emissions in 2013. To compare: commercial/residential activity accounted for 12 percent and industrial activity accounted for 21 percent. Wow.
Key findings of the study include:
Might be time to change the slogan to We Breathe What We Eat.
