"The Western Climate Initiative plans to lay the foundation for an international cap and trade program that would involve both the United States and Canada."
There are other regional initiatives across the the continent.
http://en.wikipedia.org/wiki/Western_Climate_InitiativeThe Western Climate Initiative, or WCI, is an initiative—started by states and provinces along the western rim of North America—to combat climate change caused by global warming, independent of their national governments.
The stated purpose of the WCI is to identify, evaluate and implement ways to collectively reduce greenhouse gas emissions in the region. The initiative requires partners to set an overall regional goal to reduce emissions, develop a market-based, multi-sector mechanism to help achieve that goal, and participate in a cross-border greenhouse gas registry.
