Read the paragraphs from an informative report.
First, the issue of greater fuel efficiency is ing 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 a little more than twice as much greenhouse emissions as a car that gets 50 miles per gallon. Greater fuel efficiency reduces the greenhouse gases implicated in climate change.
Having considered the relevant data, this report recommends greater effort to produce cars that are increasingly fuel efficient with each new year. This effort should come primarily from car manufacturers. The shift to greater fuel efficiency should be greatly accelerated through government assistance at the national level. Greater fuel efficiency would result in lower greenhouse-gas emissions from cars and less fossil-fuel consumption. That is one of the best ways to reduce the effects of climate change.
