Last year, two American government agencies and an international organization announced a number of policies for environmentally­friendly racing. They are known as the Green Racing Protocols(协议)．

　　The two agencies are the United States Department of Energy and the Environmental Protection Agency. The organization SAE International represents engineers and technical experts in the transportation industry. Officials from the American Le Mans Series also were involved in the effort.

　　The American Le Mans Series became the first racing event to use the protocols in its Green Challenge competition. The race was held in October of last year.

　　Last month, the World First Formula Three racing car was set to run in its first competitive race at the Formula Three Championship Final at Brands Hatch. It would have been the first biodiesel­powered car to race at Formula Three.

　　Current Formula Three rules let only gasoline­powered cars compete. Officials needed permission from all of the other Formula Three racers for the biodiesel World First car to compete. They were unable to contact one of the drivers, so the World First car was barred from the event.

　　In test runs, the World First car was the fifth fastest among Formula Three race cars. Supporters are hoping to have the fuel issue resolved in time to compete next season.
