Krugman looks at the problem of Chinese pollution

Op-Ed Columnist - Empire of Carbon - NYTimes.com

So what is to be done about the China problem?

Nothing, say the Chinese. Each time I raised the issue during my visit, I was met with outraged declarations that it was unfair to expect China to limit its use of fossil fuels. After all, they declared, the West faced no similar constraints during its development; while China may be the world’s largest source of carbon-dioxide emissions, its per-capita emissions are still far below American levels; and anyway, the great bulk of the global warming that has already happened is due not to China but to the past carbon emissions of today’s wealthy nations.

And they’re right. It is unfair to expect China to live within constraints that we didn’t have to face when our own economy was on its way up. But that unfairness doesn’t change the fact that letting China match the West’s past profligacy would doom the Earth as we know it.

Historical injustice aside, the Chinese also insisted that they should not be held responsible for the greenhouse gases they emit when producing goods for foreign consumers. But they refused to accept the logical implication of this view — that the burden should fall on those foreign consumers instead, that shoppers who buy Chinese products should pay a “carbon tariff” that reflects the emissions associated with those goods’ production. That, said the Chinese, would violate the principles of free trade.
