A new
report reveals that the United States is in the lead when it
comes to countries who produce the most automotive greenhouse gas
emissions, and it's because of relatively cheap gas.
JATO
Dynamics Ltd, a provider of automotive data, conducted a study on
the release of CO2 emissions in automotive vehicles around the world.
JATO collected figures from the United States, Europe and Japan, and
compared their greenhouse gas output.
According
to the study, the U.S.
is far behind both Europe and Japan in cutting vehicle
emissions. The United States' average CO2 emissions are 268.5 grams
per kilometer. When full size vans, small commercial vehicles and
pick-up trucks are excluded, this number drops to 255.6 g/km. In
Europe, the overall number of CO2 emissions is 140.3 g/km and Japan
takes first place for the least amount of harmful gaseous emissions
with only 130.8 g/km. The study indicates that Japanese and
European car markets "gain advantage through downsizing and
diesel adoption."
JATO
says one of the reasons for the United States' leadership
in CO2 emissions is the low price of gas. The study shows
that "the USA market is dominated by gasoline which has
81.9 percent market share, with only 1.7 percent being diesel."
Other market shares, such as Europe's, is 48.9 percent diesel fuel,
and Japan's "congested roads make very small and economical
gasoline cars a popular choice." Also, JATO's figures
reveal that "33.9 percent of vehicles sold in the U.S. still
fall within a 15-20 mpg consumption bracket, compared with only 0.28
percent in Europe and 0.63 percent in Japan."
"It
is still clear that American
consumers need to undergo a fundamental re-think of their
vehicle buying preferences, but the past period of economic upheaval
is likely to have meant that other domestic issues have taken
consumer's priority," said David Mitchell, President of JATO
Americas.
"The
blame can't just lie with consumers though, the OEM product offering
in the U.S. still does little to promote alternatives to the large
engine capacity gasoline vehicles which still dominate the market."
These
different areas in the world vary partly because of different
"CO2-based taxation regimes that reward or penalize certain
technologies." Europe's "scrappage" plans have led to
the development of fuel efficient and low polluting cars while
Japan's focus on hybrids, EVs,
and highly efficient gasoline engines.
"An
interesting point to note, is that American consumers have
been significantly
more inclined to adopt hybrid technology than the
Europeans," said Mitchell. "Hybrids have 2.3 percent market
share in the U.S. while in Europe it is still only 0.5 percent. Not
surprisingly, Japan leads the way with 10.1 percent of market share
going to hybrids."
The
U.S. may be struggling to keep up with Europe and Japan, but the
country has improved since last year. From 2009 to 2010, America's
average emissions went down by 1.0 g/km. Europe fared better dropping
4.3 g/km, while Japan's emissions wend down 0.4 g/km.
