Title: Regulation: Fuel Economy Standards Reduce Car Pollution.

Summary: Legislators can help reduce fuel consumption and pollution from cars through fuel efficiency standards. Road transport represents one of the biggest sources of CO2 emissions and air pollution. Introducing fuel economy standards for all new vehicles can go some way towards enhancing energy efficiency in the transport sector. The United States and Japan provide two examples where a gradual tightening of fuel efficiency standards has resulted in significant reduction of per vehicle fuel consumption and slower growth in the transport sector's total energy consumption. In Japan savings are expected to reach 14.7 Million Tones of Oil Equivalent (Mtoe) by 2010.
