Salt Lake City Mayor Ralph Becker and other community leaders on Saturday announced the final results of the Clear the Air Challenge in a ceremony at Pioneer Park.

"Since the Clear the Air Challenge began in 2009, Utahns have saved a total of 3.6 million vehicle miles and 6.2 million pounds of emissions," Becker said in a news release. "This is not the end of the road to help clear the air, but rather a congratulatory milestone to encourage us to reduce even more vehicle emissions for a sustainable future."

During the monthlong challenge, more than 6,000 Utah residents helped to eliminate 110,990 single-occupant vehicle trips, averting more than 1.2 million miles, which resulted in a reduction of 2.1 million pounds of emissions. Challenge winners won a variety of donated prizes, including a new Specialized bike, Real Salt Lake Club tickets, $200 in U Car Share credits, UTA monthly passes and more.
