The city of Rome will begin enforcement of a ban on “Euro 0”-rated scooters and motorcycles within a large area of the city on January 1, 2007. Most pre-1999 scooters, likely 120,000 vehicles, will not be permitted within the “anello ferrovario” area of Rome. Residents of the area may continue to ride Euro 0 bikes in the zone until November, 2007. Roman officials cite research that finds one Euro 0 vehicle can emit the same quantity of pollutants into the atmosphere as 63 uncatalyzed cars. Collectors can register vintage machines for an exemption from the ban. Reimbursements and rebates are also available to encourage riders to upgrade or scrap their older vehicles.
