Paul Krugman: Errors and Emissions

Could Fighting Global Warming Be Cheap and Free?

This just in: Saving the planet would be cheap; it might even be free. But will anyone believe the good news?

I’ve just been reading two new reports on the economics of fighting climate change: a big study by a blue-ribbon international group, the New Climate Economy Project, and a working paper from the International Monetary Fund. Both claim that strong measures to limit carbon emissions would have hardly any negative effect on economic growth, and might actually lead to faster growth. This may sound too good to be true, but it isn’t. These are serious, careful analyses.
