In amongst the stories of pessimism, pranks, and angry mobs of frost-bitten delegates, there was a little ray of hope in the news from Copenhagen today.
An agreement has very nearly been reached on Reducing Emissions from Deforestation and Degradation (REDD), a mechanism by which developing nations would be compensated with cash or carbon credits for preserving their carbon-storing forests. The idea is to make the world's forests worth more alive than dead, thus giving developing nations a strong financial incentive to favour forest preservation over mining, grazing, or other less carbon-friendly land uses.
Think of it as the carrot side of the carrot-and-stick approach to carbon pricing.
