The United States has not ratified the Kyoto Protocol (IEA, 2007, p. 90). Doing so would have committed it to reduce Green House Gases(GHG) emissions by 7% below 1990 levels by 2012. Emissions of GHGs in the US increased by 16% between 1990 and 2005. In this period, the most substantial increase in volume were emissions from energy use, followed by industrial processes.
In 2002, the US government set a goal to reduce the GHG emissions of
the US economy per unit of economic output (the emissions intensity of
the economy) .
The set goal is to reduce the GHG intensity of the US economy by 18% by
2012. To achieve this, policy has focused on supporting energy research and development, including support for carbon capture and storage (CCS), renewables, methane capture and use, and nuclear power. The America's Climate Security Act of 2007, also more commonly referred to in the U.S. as the "Cap and Trade Bill", was proposed for greater U.S. alignment with the Kyoto standards and goals.
The United States (U.S.), although a signatory to the Kyoto Protocol, has neither ratified nor withdrawn from the Protocol. The signature alone is merely symbolic, as the Kyoto Protocol is non-binding on the United States unless ratified.
