A national group that's filed petitions or lawsuits in all 50 states seeking dramatic reductions in greenhouse gas emissions hit a brick wall in Idaho, according to reporter Sean Ellis, who reports in this week's Capital Press that the Idaho Board of Environmental Quality unanimously rejected the petition at its meeting last week. The group, Kids vs. Global Warming, asked that Idaho ensure carbon dioxide emissions from fossil fuel use in the state be reduced 6 percent a year, starting in 2013, and lasting at least until 2050.

DEQ staff told the board that Idaho's biggest source of such emissions is transportation, and regulating residential emissions would be difficult; if just commercial and industrial emissions were targeted, they'd have to be reduced 25 percent a year for the state to meet the petition's goal. Agriculture groups opposed the petition. You can read Ellis' full report here.
