I cut out some to shorten the post but there is more
and it might have some of the info you were looking for.
Also has a bunch of links at the bottom.
The United States, with the world's largest economy, is also the
world's largest single source of anthropogenic (human-caused)
greenhouse gas emissions. Quantitatively, the most important
anthropogenic greenhouse gas emission is carbon dioxide, which is
released into the atmosphere when fossil fuels (i.e., oil, coal, natural
gas) are burned. Current projections indicate that U.S. emissions of
carbon dioxide will reach 5,985 million metric tons in 2005, an increase
of 1,083 million metric tons from the 4,902 million metric tons emitted
in 1990, and around one-fourth of total world energy-related carbon
emissions. At the December 1997 global warming summit in Kyoto,
Japan, the U.S. delegation agreed to reduce U.S. carbon emissions 7%
from 1990 levels by 2008-2012. Given current EIA projections, it is
unlikely that this goal will be met.
In February 2002, the Bush Administration released its proposed
alternative to the Kyoto Treaty, calling for significant reductions in
emissions of various pollutants (mercury, nitrogen oxide, sulfur dioxide).
The program, known as the "Clear Skies Initiative,"
On March 27, 2001, the Bush administration declared that the United
States had "no interest" in implementing or ratifying the Kyoto treaty
limiting greenhouse gas emissions, but that it would pursue other ways of
addressing the climate change issue. On April 12, 2001, the White House
affirmed Clinton administration-approved energy efficiency standards for
washing machines and water heaters. Under these standards, clothes
washers would become 22% more efficient by 2004 and 35% more by
2007. In January 2002, Energy Secretary Spencer Abraham announced
an initiative, known as "Freedom CAR," to help automakers produce
fuel-cell-powered electric vehicles. And in January 2002, President Bush
proposed a new hydrogen fuel cell vehicle initiative. On April 2, 2004, the
Energy Department agreed to require new central air conditioners and
heat pumps to be 30% more efficient beginning in 2006. The Energy
Department had attempted to set the standard, lower, at 20%, but a
January 2004 court ruling prevented the Department from doing so.
