nergy-related
carbon emissions by the United States remained flat in 1998 despite
four percent economic growth. This is the first time in nearly
a decade that U.S. carbon emissions have not increased. In fact,
the latest numbers show that emissions decreased slightly.
According
to newly available data from the Energy Information Administration
of the U.S. Department of Energy, this was the first year since
1991 that U.S. carbon emissions did not rise. Emissions from
the burning of fossil fuels were about 1,476 million metric tons
of carbon (MTc) in 1998, about 2 MTc (0.15%) less than emissions
in 1997 but 138 MTc (10.3%) above emissions in 1990.
"This
is good news for the worldwide effort to combat global warming.
It indicates that the U.S. economy can grow at a healthy pace
without higher energy use or more greenhouse gas pollution, said
Howard Geller, Executive Director of the American Council for
an Energy-Efficient Economy (ACEEE). "Although more analysis
is needed to understand the causes for this recent trend, no
doubt the growing influence of policies such as appliance efficiency
standards and the EPA/DOE Energy Star labeling and promotion
programs contributed to these favorable results," Geller
noted. Other factors cited included increased conservation and
the growth of the Internet.
While encouraging,
1997 emissions were still much higher than 1990 emissions. In
contrast to growth in carbon emissions in the United States during
the 1990s, emissions have remained flat or even fallen in some
Western Europe nations. The United Kingdom recently reported
that its greenhouse gas emissions declined 9 percent between
1990 and 1997. This was achieved in spite of the fact that the
U.K. already emits less than half as much per capita as the United
States.
"The
United States will not come close to returning carbon and other
greenhouse gas emissions to their 1990 levels by 2000, the voluntary
commitment made by the United States as part of the Framework
Convention on Climate Change agreed to in Rio de Janeiro in 1992
and ratified by the U.S. Senate," added Jennifer Thorne,
ACEEE Research Associate.
"Although
growth in U.S. carbon emissions has been curtailed at least temporarily,
the United States must do more to cut greenhouse gas pollution,"
said Geller.
ACEEE recommends:
- Replacing older, dirty coal-fired power plants
with cleaner, highly efficient cogeneration systems and natural
gas-fired power plants;
- Increasing the average fuel economy of new
passenger vehicles significantly through tougher standards and
financial incentives;
- Restraining growth in energy use in both
residential and commercial buildings through new appliance efficiency
standards, improved building codes, and other mechanisms.
