The Story of Cap and Trade
Although they sound similar, Cap and Trade and Cap and Share are entirely different approaches to climate change:
CAP and SHARE (www.capandshare.org) is a system which can be used to CAP (to limit and dramatically reduce the carbon coming into the country in line with the science), and to SHARE (to distribute the revenue raised to ensure people have the money to cope with the increased price in all goods and services which have carbon content).
In contrast, CAP and TRADE (the EU response to climate change, and the approach being proposed at Copenhagen) simply enables business as usual (soaring emissions, soaring fuel prices and soaring profits for the heavy emitters) to continue.
