Moreover, the window of opportunity for action that will make a difference is narrow - that is, the next 10 to 15 years.

Throughout the North, however, there is strong resistance to changing the systems of consumption and production that have created the problem in the first place and a preference for "techno-fixes," such as "clean" coal, carbon sequestration and storage, industrial-scale biofuels, and nuclear energy.

Globally, transnational corporations and other private actors resist government-imposed measures such as mandatory caps, preferring to use market mechanisms like the buying and selling of "carbon credits," which critics say simply amounts to a licence for corporate polluters to keep on polluting. In the South, there is little willingness on the part of the southern elite to depart from the high-growth, high-consumption model inherited from the North, and a self-interested conviction that the North must first adjust and bear the brunt of adjustment before the South takes any serious step towards limiting its greenhouse gas emissions.
