Sustainable Ventures is offering a $10,000 prize to anyone who can measure the “true costs” of a loaf of bread. The idea is an exercise to produce metrics and frameworks upon which people can make more informed choices. Given the zillions of types of bread consumed around the world, a “true cost” will be pretty varied, but the way the cost is calculated and the areas for “savings” exposed are likely to be similarly useful.
The added costs in question would probably be derived from oil used in transport and fertilizer and associated externalities as well as the theoretical costs of things like low or high wages.
