Editorial: Carbon tax would hurt, not help US

The combined emissions of six key air pollutants dropped 73 percent between 1970 and 2017 even while GDP soared 262 percent and energy consumption rose 44 percent increased.

New cars, trucks, SUVs and heavy-duty trucks and buses run about 99 percent cleaner than models produced in 1970, helping reduce pollution even as vehicle miles traveled nearly tripled.

It’s important to recognize this success — not as a victory lap, but as a roadmap. If we draw the right conclusions, we can build on our progress.
