Springtime for Toxics, by Paul Krugman, Commentary, NY Times:

Here’s what I wanted for Christmas: something that would make us both healthier and richer. And since I was just making a wish, why not ask that Americans get smarter, too?

Surprise: I got my wish, in the form of new Environmental Protection Agency standards on mercury and air toxics for power plants. ...

As far as I can tell, even opponents of environmental regulation admit that mercury is nasty stuff. It’s a potent neurotoxicant... The E.P.A. explains: “Methylmercury exposure is a particular concern for women of childbearing age, unborn babies and young children, because studies have linked high levels of methylmercury to damage to the developing nervous system, which can impair children’s ability to think and learn.”

That sort of sounds like something we should regulate, doesn’t it?

The new rules would also have the effect of reducing fine particle pollution, which is a known source of many health problems... The ... payoff to the new rules is huge: up to $90 billion a year in benefits compared with around $10 billion a year of costs in the form of slightly higher electricity prices. ...

And it’s a deal Republicans very much want to kill.

With everything else that has been going on in U.S. politics recently, the G.O.P.’s radical anti-environmental turn hasn’t gotten the attention it deserves. ... And I’m not exaggerating: during the fight over the debt ceiling, Republicans tried to attach riders that ... would essentially have blocked the E.P.A. and the Interior Department from doing their jobs.

[...]

More generally, whenever you hear dire predictions about the effects of pollution regulation, you should know that special interests always make such predictions, and are always wrong. For example, power companies claimed that rules on acid rain would disrupt electricity supply and lead to soaring rates; none of that happened, and the acid rain program has become a shining example of how environmentalism and economic growth can go hand in hand.
