Environmental groups seek cleaner vehicles
During the past six months, President George W. Bush has upset environmentalist groups. Within 60 days of his inauguration, Bush had reneged on his campaign promise to force energy companies to reduce carbon dioxide emissions. And, in March, the Bush administration rejected the Kyoto Protocol, which is committed to reducing greenhouse emissions in 37 industrialized nations. Bush has expressed concerns that emission reductions may have a negative impact on the U.S. economy and has questioned the science behind global warming. But scientists and environmental groups feel that global warming is a serious and real dilemma.
