Salt Lake City Mayor Jackie Biskupski has joined a national effort to encourage U.S. cities to transition to clean energy.

Biskupski joins mayors from Miami Beach, Fla., Columbia, S.C. and San Diego as leaders of the Sierra Club's "Ready for 100" campaign, which aims to persuade 100 cities to make a commitment similar to one made by Utah's capital last summer.

"Climate change is one of the most challenging issues of our time," Biskupski said in a news release. "Progress depends on collaboration. I'm looking forward to sharing our example of how that's working in Salt Lake City, while encouraging other leaders across the country to join with us in this historic commitment."

Though the Utah chapter of the Sierra Club endorsed incumbent Ralph Becker before the 2015 mayoral election, Biskupski joined with the City Council in resolving to transition to 100 percent clean energy by 2032 and reduce greenhouse gas emissions 80 percent by 2040.

The city outlined its long-term climate and energy goals in a plan dubbed "Climate Positive 2040."
