An executive order of Governor Brewer created a new Climate Change Oversight Group, staffed and coordinated by the Department of Environmental Quality, tasked with monitoring Arizona's participation in the Western Climate Initiative and any potential cap-and-trade initiatives. The executive order also mandated that, in consultation with the Department of Environmental Quality, all state agencies must purchase vehicles that meet fuel and emissions requirements with the goal that by January 2012 all state owned vehicles will be hybrids, meet low-greenhouse gas (GHG) emission standards, or use low-GHG alternative fuels. http://www.azsos.gov/public_services/Register/2010/31/governor.pdf pp. 1424-26.
