After enduring changes and much debate in the House, a resolution supporting clean air made it out of the Senate unscathed Wednesday.

HJR5, which would encourage drivers to not idle their vehicles in an attempt to lessen the impact on Utah's air quality, was passed on the Senate floor unanimously.

Last week, when it came before the House, Rep. Mike Noel, R-Kanab, and other climate change skeptics, successfully amended the resolution to remove all references to carbon dioxide.

Sixth graders from Morningside Elementary looked on, wearing "Team Hope" T-shirts -- the motto they used while they researched and proposed the idea -- as Senate Minority Leader Pat Jones, D-Holladay, the bill's sponsor, explained the resolution.

Jones read letters from some of the students involved in the project recounting their experiences.

"I can make a difference by just talking about it," wrote Gabe, one of the students. "It is so simple, but it makes a substantial difference."
