First, the issue of greater fuel efficiency is helping
to remedy climate change. If all the cars on our roads

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.
Add this sentence at the end: "Fuel efficiency can
