Salt Lake City Mayor Erin Mendenhall and Scott Baird, executive director of the Utah Department of Environmental Quality, jokingly fight over a trophy before the kickoff of the 11th annual Clear the Air Challenge at the Capitol in Salt Lake City on Friday. The Clear the Air Challenge, issued by business, government and community leaders, is a monthlong competition starting Saturday that gives Utahns the chance to reduce their vehicle emissions by choosing alternatives to driving alone. The Utah Department of Environmental Quality won the challenge in 2019. According to Baird, DEQ employees won by increasing their use of public transportation and inviting food trucks to their office location so that employees did not have to go out for lunch. The Clear the Air Challenge is a partnership between the Salt Lake Chamber, TravelWise and UCAIR. To learn more about the challenge, log on to cleartheairchallenge.org.
