United States The United States (U.S.), although a signatory to the Kyoto Protocol, has neither ratified nor withdrawn from the Protocol. The signature alone is symbolic, as the Kyoto Protocol is non-binding on the United States unless ratified. The United States was, as of 2005, the largest single emitter of carbon dioxide from the burning of fossil fuels.<42>. China is projected to take over at the top of the table by 2030.<43>
On July 25, 1997, before the Kyoto Protocol was finalized (although it had been fully negotiated, and a penultimate draft was finished), the U.S. Senate unanimously passed by a 95–0 vote the Byrd-Hagel Resolution (S. Res. 98),<44><45> which stated the sense of the Senate was that the United States should not be a signatory to any protocol that did not include binding targets and timetables for developing as well as industrialized nations or "would result in serious harm to the economy of the United States". On November 12, 1998, Vice President Al Gore symbolically signed the protocol. Both Gore and Senator Joseph Lieberman indicated that the protocol would not be acted upon in the Senate until there was participation by the developing nations.<46> The Clinton Administration never submitted the protocol to the Senate for ratification.
The Clinton Administration released an economic analysis in July 1998, prepared by the Council of Economic Advisors, which concluded that with emissions trading among the Annex B/Annex I countries, and participation of key developing countries in the "Clean Development Mechanism" — which grants the latter business-as-usual emissions rates through 2012 — the costs of implementing the Kyoto Protocol could be reduced as much as 60% from many estimates. Other economic analyses, however, prepared by the Congressional Budget Office and the Department of Energy Energy Information Administration (EIA), and others, demonstrated a potentially large decline in GDP from implementing the Protocol.
The current President, George W. Bush, has indicated that he does not intend to submit the treaty for ratification, not because he does not support the Kyoto principles, but because of the exemption granted to China (the world's second largest emitter of carbon dioxide<47>). Bush also opposes the treaty because of the strain he believes the treaty would put on the economy; he emphasizes the uncertainties which are present in the climate change issue.<48> Furthermore, the U.S. is concerned with broader exemptions of the treaty. For example, the U.S. does not support the split between Annex I countries and others. Bush said of the treaty:
This is a challenge that requires a 100% effort; ours, and the rest of the world's. The world's second-largest emitter of greenhouse gases is the People's Republic of China. Yet, China was entirely exempted from the requirements of the Kyoto Protocol. India and Germany are among the top emitters. Yet, India was also exempt from Kyoto … America's unwillingness to embrace a flawed treaty should not be read by our friends and allies as any abdication of responsibility. To the contrary, my administration is committed to a leadership role on the issue of climate change … Our approach must be consistent with the long-term goal of stabilizing greenhouse gas concentrations in the atmosphere."<49>
Despite its refusal to submit the protocol to Congress for ratification, the Bush Administration has taken some actions towards mitigation of climate change. In June 2002, the American Environmental Protection Agency (EPA) released the "Climate Action Report 2002". Some observers have interpreted this report as being supportive of the protocol, although the report itself does not explicitly endorse the protocol. At the G-8 meeting in June 2005 administration officials expressed a desire for "practical commitments industrialized countries can meet without damaging their economies". According to those same officials, the United States is on track to fulfill its pledge to reduce its carbon intensity 18% by 2012.<50> The United States has signed the Asia Pacific Partnership on Clean Development and Climate, a pact that allows those countries to set their goals for reducing greenhouse gas emissions individually, but with no enforcement mechanism. Supporters of the pact see it as complementing the Kyoto Protocol while being more flexible, but critics have said the pact will be ineffective without any enforcement measures.
In September 2006 the journal Nature reported that the National Oceanic and Atmospheric Administration had blocked an internal report which concluded that global warming caused by greenhouse gas emissions may be contributing to the frequency and strength of hurricanes.<51>
The Administration's position is not uniformly accepted in the U.S. For example, Paul Krugman notes that the target 18% reduction in carbon intensity is still actually an increase in overall emissions.<52> The White House has also come under criticism for downplaying reports that link human activity and greenhouse gas emissions to climate change and that a White House official and former oil industry advocate, Philip Cooney, watered down descriptions of climate research that had already been approved by government scientists, charges the White House denies.<53> Critics point to the administration's close ties to the oil and gas industries. In June 2005, State Department papers showed the administration thanking Exxon executives for the company's "active involvement" in helping to determine climate change policy, including the U.S. stance on Kyoto. Input from the business lobby group Global Climate Coalition was also a factor.<54>
In 2002, Congressional researchers who examined the legal status of the Protocol advised that signature of the UNFCCC imposes an obligation to refrain from undermining the Protocol's object and purpose, and that while the President probably cannot implement the Protocol alone, Congress can create compatible laws on its own initiative.<55>
