Surroundings of Automobiles Three major issues : Energy, CO2 reduction, Air quality Global Warming Energy CO2 reduction Urban Environment CO2 Energy Emissions
Current situation of Japan Population : 127miliion Motor vehicles : 78 million units passenger cars : 58 million truck/bas : 20 million motorcycle : 4 million No. of Motor vehicles per 1,000 persons total motor vehicles :594 passeneger cars : 496
Relationship Between the Automobile and dthe Environment/Energy Issues The issues do not simply involve higher added value but issues in responding to social demand d in terms of energy, the environment, etc. Air pollution problems Emission (NOx, HC, PM, etc.) Global warming Emission (CO2) Fuel economy, energy conservation, etc. VS Waste disposal Processing, disposal and recycling of end-of-life vehicles Traffic accidents Safety 4

CO2 Reduction in Transportation Sector After reaching the peak in 2001, CO2 emissions in the transport sector have been on the decrease. The CO2 reduction in the transport sector is attributable to: 1) decreased travel distance, 2) increased fuel efficiency, and 3) improved traffic flow.

Government Policy Effective Policy for promoting Clean Vehicles Without control to hold of passenger cars, The most effective method of combination of regulation and treatment Regulation to makers 1Fuel economy 2Emission regulations Incentive measures to Consumer 3Tax incentive 4subsidy Supplies clean car in market Support clean car purchase of consumers Promoting Clean vehicles 19
Three Actions Required for Environmental/Energy Control (1) Action for air pollution problem Radical reduction of toxic substances in exhaust gas (2) Action for global warming problem Radical reduction of CO 2 emission volume (3) Action for energy control Energy countermeasures in the transportation sector dependent excessively on oil (Use of oil-alternative fuels, etc.) Solving the three problems in balance is required. 20
For Sustainable Future In future, Increase of car use cancel effort for emission reduction in Asia. Our slogan is Ever Onward. JARI wants to have the information exchange continuously with you to solve these problems.
Conclusion: For Better Air Quality in Asia Needs Effective Policies Needs Consensus Needs Public Awareness 22
