Researchers found that grains and sweets had lowest greenhouse gas emissions (GHGEs). Animal products, including meat and dairy, had higher GHGE values.
Now, we put out a lot of carbon dioxide every year,
over 26 billion tons. For each American, it's about 20 tons. For people in
poor countries, it's less than one ton. It's an average of about five tons
for everyone on the planet. And, somehow, we have to make changes that will
bring that down to zero.

There is no Carbon Footprint Czar (yet), but imagine when one is appointed. You will then be a lot more aware of a very concerned and polluted world.
The January, 2015 issue of the American Journal of Clinical Nutrition includes a study in which energy and nutrient density of various foods were determined, and then compared to their carbon footprints.
Researchers from the Center for Public Health Nutrition at the University of Washington, cooperated with scientists at the Institute of Cardiometabolism and Nutrition in Paris as well as the French food conglomerate, Danone to establish their disturbing conclusions.
Researchers found that grains and sweets had lowest GHGEs. Animal products, including meat and dairy, had higher GHGE values.
Considerations of the environmental impact of foods need to be linked to concerns about nutrient density and health. The point at which the higher carbon footprint of some nutrient-dense foods is offset by their higher nutritional value is a priority area for additional research.
One can only imagine the behind-the scenes (passionate) discussions between the world's largest dairy producer (Danone) and concerned scientists possessing zero conflicts of interest.
Becoming vegan is the most important and direct change
we can immediately make to save the planet and its species.
