GREENSBORO, N.C. – More than 300 fleet managers from governments across North Carolina gathered in Greensboro Apr. 18 to learn about alternative fuels and new fuel-saving technologies to cut emissions from vehicles, according to the Winston-Salem Journal. The conference, Mobilizing North Carolina: Where Air Quality, Energy and Transportation Meet, was held at the Greensboro Coliseum Annex. It was organized by the N.C. Solar Center and sponsored by various environmental and transportation agencies. The N.C. Solar Center is a clearinghouse based at N.C. State University for information, research, and training related to renewable technologies. The center has held at least two other conferences in Raleigh in the past few years to promote alternative fuels and emissions reduction. However, this was the first conference held in the Triad, and it drew the biggest crowd. The goal of the conference was to raise awareness about ways to improve fuel efficiency and reduce emissions and greenhouse gases, such as carbon dioxide, which scientists believe is responsible for global warming. Currently, 24 counties across the state, including several in the Triad, do not meet national air-quality standards.
