A federal judge ruled that government agencies are failing to comply with a law requiring them to purchase alternative-fuel vehicles (AFVs), reported the San Francisco Chronicle. The report said the judge also criticized government information efforts in informing the public about compliance. The post-Gulf War law required government agencies in metropolitan areas to buy more vehicles running on cleaner-burning fuels, to reduce dependence on foreign oil. By 1999, 15 government agencies were supposed to have leased or purchased enough AFVs to constitute 75 percent of their respective fleets, with exceptions for police cars, off-road vehicles and some military vehicles. In the case brought by the Center for Biological Diversity, the Sierra Club and the Bluewater Network, the judge has required agencies to bring their reporting up to date, and has called for clarifications on applying the law to local governments and private rental car companies.
