Continuing its staunch refusal to ratify the Kyoto Protocol, the U.S. nevertheless joined forces with China, Australia, India, Japan, and South Korea in the Asia-Pacific Partnership for Clean Development and Climate (AP6). These countries, which produce 50% of the world’s greenhouse gas emissions, have agreed to set individual national goals for reducing these emissions. Like a younger sibling intent on distancing itself from the older Kyoto even if it means being an underachiever, the AP6 has no built-in enforcement mechanism.
