TO THE EDITOR:
"U.S. reverses Trump effort to quash California vehicle emissions rules" (autonews.com, Dec. 22) really describes a major step backward. Increasing fuel economy requirements just extends using the problem, gasoline, the largest single emitter of new carbon dioxide. Gasoline emits more new CO2 than the coal and natural gas used to produce electricity combined.
The best solution is to ban the sale of new gasoline-powered vehicles, leave existing vehicles alone to live out their lives on gasoline, and let car companies and consumers figure out what they want to make and buy. They will figure it out super fast, and 15 years from the date of the ban, we'll have our entire fleet of cars, SUVs and pickups powering our economy with either electricity, hydrogen or ethanol. Global warming and sea level rise will have come to a screeching halt.
