A whole slew of countries and states have signed on to a new International Carbon Action Partnership, with a goal of sharing knowledge about and standardizing best practices for what they hope will become a global cap-and-trade system. Participants include members of the Western Climate Initiative and Regional Greenhouse Gas Initiative, as well as various European countries and New Zealand. “By working together we can make our shared vision of a global carbon market a reality,” said British Prime Minister Gordon Brown. Added California Gov. Arnold Schwarzenegger, “Just because you don’t see Washington leading on this issue don’t assume that America is shirking its responsibilities.” Zing!
