Salt Lake City will be hosting a Step It Up movement urging Congress to step up its efforts to reduce carbon emissions by 80 percent by the year 2050.
More than 1,000 communities nationwide will participate in the event taking place on Saturday. Five popular bands and the Grammy-winning Los Lobos will perform at the free event being held at Washington Square from 3 to 10 p.m. Attendees will also have the opportunity to hear from environmental speakers, see clean-air cars on display, visit booths from local businesses and organizations, and enjoy a children's play yard.
