Expressing the sense of the Congress regarding the negotiation of an international climate change agreement.

Urges the United States to take all necessary steps to protect the Earth's climate and to take a leadership role in negotiating an international climate change agreement that: (1) contains legally binding targets and timetables beginning in 2005 for reducing greenhouse gas emissions substantially below 1990 level; (2) provides for participation by developing nations; and (3) is fair, enforceable, and provides options for nations to achieve necessary greenhouse gas reductions in a cost-effectiveness manner.
