Before you go to bed tonight, or maybe when you wake up Monday, this article in the NYT Sunday magazine is worth checking out – the promise, and reality, of carbon trading as a way of reducing global CO2 emissions.

Probably the most telling thing about the article is that the current US trading regime is entirely voluntary, and only requires a 1% reduction in CO2, and the big players still refuse to sign on.
