First, the issue of greater fuel efficiency is helping
to remedy climate change. If all the cars on our roads
got 50 miles per gallon, greenhouse emissions
produced by automobiles would be cut enormously. A
car that gets 25 miles per gallon produces about a
little more than twice as much carbon dioxide as a car
that gets 50 miles per gallon, Greater fuel efficiency
reduces the greenhouse gases implicated in climate
change.
