Clear Thinking on Smog

Re “Smog Rules May Be Eased,” July 27: I thought the objective is to reduce smog, not to rearrange it. If successful smog reduction can be traded to other smog producers, where is the environmental gain? Wouldn’t it be more effective ecologically to reward companies that reduce their smog production with tax and financial incentives, rather than to let them sell their smog credits to others who can continue to pollute?
