Editor,As a concerned resident, I am doing everything I can to reduce emissions on red air days. We've lowered our thermostat and don't burn wood on red air days. We drive a low emission vehicle, carpool, bike, or take mass transit, and pool all our trips.But, with apologies to Governor Herbert and Rep. Brad Dee, I must take issue with some of the numbers being used to describe the sources of pollution that affect us all during the winter inversions (Feb. 17 guest commentary, "Real solution to air quality"). The Utah Department of Air Quality, along with the governor and Rep. Dee, report that vehicle emissions represent 57 percent of the inversion pollution, with industry accounting for only 11 percent. Drive less, they tell us, and do your part.
