Last month Wiley published derivatives whizkid Richard Sandors’ new book Good Derivatives: A Story of Financial and Environmental Innovation. Sandor is a firm believer that markets can play a sound part in helping solve environmental problems, and even believes that the often reviled financial instrument, a derivative, can help. He founded the Chicago Climate Exchange, which closed in 2010, and Sandor is still touting its success and his belief in cap and trade, saying the system cost $3 billion, had $120 billion in benefits and saved 32,000 lives. No doubt creating a market in which emitting carbon had a clear cost that could be hedged and managed with derivatives would bring a concrete cost to not just GHGs, but broad pollutants and the problem on the horizon–water scacity. Now to mustering the will to get corporations to participate.
