I believe many people are really wanting improve their environmental impact and thus unfortunately carbon footprint is not a good enough proxy. Water use and water pollution are just two factors that are probably more significant, and have a broader, faster impact on biodiversity. For example: Growing 1 almond (a low emission nut) uses about a gallon of water. Dairy cattle have a terrible impact on waterways with run-off and animal wallowing.
