Why is it OK to trade carbon credits internationally?
Because this mirrors the physical behavior of carbon in the atmosphere. Carbon dioxide released into the atmosphere in Wisconsin may travel to England, then Egypt, then Zimbabwe before it is absorbed by living matter. In fact, it could wander locally or globally for years, even centuries, before it is snared by a plant or breaks down in the atmosphere. From this perspective, the atmosphere is a pool, and you can add or subtract carbon at any point and influence the amount in the pool. ? ?International carbon trading’s utility is to help man regulate the global atmospheric level of carbon dioxide and other greenhouse gases.
