Après les permis d'émission de CO2 dans l'industrie, certains verraient bien éclore la même idée pour les émissions de... calories et la lutte contre l'obésité.
Brave New World... :
Medical and public health attempts to control obesity should continue, but it is time to add marketplace approaches. The first step is realizing that, nationally, weight gain is not a medical problem, it's a pollution problem. (...)
A program for tradable emission allowances could target foods with a high caloric density, that is, foods with a high number of calories per ounce. (...)
A specific example illustrates how tradable emission allowances could work. Suppose the calorie-emission allowance is set to 100 calories for each ounce of food emitted into the environment (i.e., sold). A four-ounce food item having more than 400 calories could not, therefore, be sold unless "calorie credits" were purchased to cover the excess calories. So a standard four-ounce stick of butter, containing 780 calories, could not enter the marketplace until the butter producer acquired 380 additional calorie-credits from someone having credits to sell.
