Greendex, Consumer Choice and the Environment - A Worldwide Tracking Survey

National Geographic identifies food consumption trends for the U.S. compared with other major countries like China, Brazil, and Canada, in an effort to measure and compare the sustainability of consumer choices in 14 countries. The food sustainability score is achieved by weighing a variety of factors, most importantly the consumption of meat and seafood, fruit and vegetables, and locally grown foods. The report also covers related items such as knowledge and awareness of environmental issues.
