Transportation, Air Pollution, ClimateThe Road Ahead in Asia August 19, 2014 Michael P. Walsh International Consultant Founding Chairman Board of Directors, International Council on Clean Transportation
Air Pollution Is Already Reaching Crisis Levels Across Asia Especially PM2.5 And O3 PM2.5 卫星反演PM2.5浓度分布 Van Donkelaar et al. (2010) O3 模拟O3浓度分布 Lelieveld, J., and F. J. Dentener (2000)
Ambient PM2.5 Now Among The Leading Global Risks For Mortality And Lost Years Of Healthy Life In 2010 Contributes to 3.2 million premature deaths worldwide
Costs of Air Pollution:Health Impacts of Road Transport • Cost to Advanced Economies Plus China and India = $3.5 Trillion per Year • OECD ~ $1.7 Trillion • China ~ $1.4 Trillion • India ~ $0.5 Trillion • In OECD Countries ~ Half From Road Transport Source: OECD Secretary General Gurria, , May 21, 2014

Remember 2011! Severe Drought Followed By Extreme Flooding
Historical High Growth Has Offset Many ImprovementsVehicles Remain Important Contributor To Local, Regional and Global Pollution
BC: Linking Climate and Air Pollution • Black Carbon (BC) is part of the air pollution mixture known as particulate matter (PM) • Most strongly light-absorbing component of PM • Formed by incomplete combustion of fossil fuels, biofuels, and biomass, and is a major component of “soot” • Mainly found in the fine particle (PM2.5) fraction, which is most strongly linked to adverse health effects
Elements of a ComprehensiveVehicle Pollution Control Strategy Better Air Quality Clean Vehicle Technologies Low Emissions Clean Fuels Transportation & Land use Planning Appropriate Maintenance
Diesel Vehicles and Engines are Ideal Candidates for Black Carbon Control Very high ratio of Black Carbon to Organic Carbon Ubiquitous Control Technology Exists Substantial Health Co-Benefits
A Critical Technology: Diesel Particulate Filters (DPFs) Trapped Soot Cell Plugs Exhaust Out (CO2, H2O) Exhaust In(PM, CO, HC) *Removes 90+% BC, PM; also HC and CO *Requires Ultralow Sulfur Diesel (ULSD) 21

Dealing With Existing VehiclesMust Be A High PriorityWill Dominate Inventory For Several Years
Strategies For In-use Vehicles • Mandatory Retirement (Scrappage) • Best applied to the oldest vehicles • Can be the most cost-effective reduction strategy • Retrofit • The installation of emissions control equipment on vehicles not yet ready for retirement • Requires Ultra Low Sulfur Diesel (< 50 PPM) For Most Advanced PM Filters
