Kyoto Protocol
The objective of the protocol is the "stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system." As of June 2007, 175 Parties have ratified the Protocol to date. Of these, 36 countries and the EEC are required to reduce greenhouse gas emissions below levels specified for each of them in the treaty. (representing over 61.6% of emissions from Annex I countries). Notable exceptions include the United States and Australia. One hundred thirty seven countries have ratified the protocol, but have no obligation beyond monitoring and reporting emissions. As of August 31, 2007, 663 US cities in 50 states, representing more than 72 million Americans support Kyoto after Mayor Greg Nickels of Seattle started a nationwide effort to get cities to agree to the protocol.
