But 10 fisheries, stretching from the halibut fishery off Alaska to the surf clam industry in New England, have tried a different route.
They have capped their annual catch and then granted fishermen the right to a certain share of that catch. The fishermen can buy and sell these rights among themselves, creating a market that rewards the most efficient companies. The fishermen also have a stake in the long-term health of the fishery, as it will dictate the value of their fishing rights when they retire.
The new study is important because it shows that the benefits aren’t just hypothetical. At the 10 fisheries, there are fewer fatal accidents than elsewhere and the fish populations are healthier. The fact that halibut has returned to restaurant menus in the last decade is a direct result of these cap-and-trade programs.
All of the climate bills in Congress revolve around a similar idea. The government would cap greenhouse-gas emissions and issue tradable permits, each giving power plants the right to pump out a set amount. The plants that did the best job of reducing their emissions could then profit by selling unused permits to inefficient plants. A similar system put in place during George H. W. Bush’s presidency reduced acid rain much more quickly than economists had predicted.
