I was on NPR's Marketplace this evening with a commentary titled, "We need a carbon tax on gasoline." Here's the teaser:
Can you put a price on pollution? That's the question Congress takes up this week as they begin debate on the Climate Security Act of 2008. The legislation would enact a cap-and-trade system, whereby large polluters would buy and sell emission permits.
Commentator and economist Andrew Samwick has taken a look at his carbon output and his family's. He says if we're serious about cleaning up our act, we should consider a straight tax on carbon.
In a nutshell, while it is true that the largest part of our emissions come from automobiles, plenty still come from heating our homes and traveling by air. The more emission reduction we can get at the thermostat and in the air, the less we need to squeeze out of automobiles.
