Inefficient reducer

摘要

A University of California-Davis professor estimates the federal government's Cash for Clunkers program is paying 10 times more per ton to reduce carbon emissions as it would pay under a cap-and-trade system. UC Davis transportation economist Christopher Knittel analyzed the cost of the Cash for Clunkers program as compared to the cost of carbon credits. While carbon credits are projected to sell in the United States for about $28 per ton, even the best-case calculation of the cost of the clunkers rebate is $237 per ton, said Knittel said.
