How is Diet Related to Climate Change?

The nutritional footprint – integrated methodology using environmental and health indicators to indicate potential for absolute reduction of natural resource use in the field of food and nutrition (10 page pdf, Melanie Lukas, Holger Rohn, Michael Lettenmeier, Christa Liedtke, Klaus Wiesen, Journal of Cleaner Production, Feb. 9, 2015)

Today we review the concept of a numerical index used to assess the impact of various diets and nutrients on health and the environment by examining how they affect greenhouse gas emissions, and water or land demand and use. A vegetarian diet has low impact, a fish diet medium impact and a meat diet high impact. The authors suggest how this index could be used to help consumers choose lower impact diets as a sort of Weight Watcher index tagged to foods at retail outlets.
