This is a “what if” type of idea but something that hopefully is not that far off in the future. The idea is to have each label include the carbon footprint information available for all to see. Knowing what the “environmental cost” of the food or product you are about to consume is every bit as important as the nutritional contents. From Global Warming Diet:
Since all foods have a carbon footprint (carbon emissions associated with their production and transportation), what if food labels also contained information about the associated carbon emissions? At top is an example of what such a label might look like for a jar of peanut butter. Accompanying the standard nutritional information is the carbon footprint or the CO2e emissions per serving and for the entire jar. These calculations were made by EcoSynergy, one of our innovative risk takers (chapter 7), who computed the energy to farm, produce, and transport peanut butter. The label also includes a carbon rating scale between 1 and 10, so that consumers can better choose.
