On May 30, 2008, some of the world’s top economists ( including five Nobel laureates) will finalize a prioritized list of some of the best and worst solutions for the world’s most pressing problems. 

The Copenhagen Consensus panel will look at the costs vs. benefits of almost 50 solutions to worldwide issues.  Bjorn Lomborg, organizer of the Copenhagen Consensus and author of Cool It:  The Skeptical Environmentalist’s Guide to Global Warming compares a dollar spent on heart disease in a developing nation that does $25 worth of good with the 90 cents worth of good for each dollar spent on carbon mitigation as an example.

Stay tuned as this group determines the best cost/benefit answers to problems ranging from air pollution to public health to trade barriers.  Economists might seem cold when they put a dollar figure on an emotional topic–but finding the best investments to help the planet is their goal.  And if those dollars aren’t spent well, we all lose.
