Paul Krugman: Pollution and Politics

Earlier this week, the Environmental Protection Agency announced proposed regulations to curb emissions of ozone, which causes smog, not to mention asthma, heart disease and premature death. And you know what happened: Republicans went on the attack, claiming that the new rules would impose enormous costs.

There’s no reason to take these complaints seriously, at least in terms of substance. Polluters and their political friends have a track record of crying wolf. Again and again, they have insisted that American business — which they usually portray as endlessly innovative, able to overcome any obstacle — would curl into a quivering ball if asked to limit emissions. Again and again, the actual costs have been far lower than they predicted. In fact, almost always below the E.P.A.’s predictions.
