Presentation on theme: "1 THE ENVIRONMENT AND MOTOR VEHICLE EMISSIONS. 2 Motor vehicle emissions are major contributors to health risks and environmental damage at the local,"— Presentation transcript:
2 Motor vehicle emissions are major contributors to health risks and environmental damage at the local, regional and global levels The rapid growth in vehicle use expected over the next few decades will impair current efforts to control emissions of conventional pollutants while substantially increasing highway emissions of greenhouse gases. Key observations from an OECD study MOTOR VEHICLE POLLUTION : Reduction Strategies beyond 2010
3 Long-term solutions to environmental problems such as tropospheric ozone concentrations and CO2 emissions will require substantial reductions in fossil fuel use through a combination of fuel efficiency improvements, substitution of new, cleaner fuels and moderate, controlled levels of annual traffic growth. Key observations from an OECD study MOTOR VEHICLE POLLUTION : Reduction Strategies beyond 2010
4 An integrated approach to transport, energy and environmental issues will become increasingly essential to an emissions control policy capable of achieving long term goals. Key observations from an OECD study MOTOR VEHICLE POLLUTION : Reduction Strategies beyond 2010
5 Transport sector contribution to atmospheric emissions OECD Europe and North America, 1986
6 Share of annual U.S. cancer cases related to air pollution
7 Cancer risk shares of motor vehicle related toxic air pollutants
8 Urban air quality and motor vehicle emissions research at Carleton University the measurement and characterization PM and VOCs in urban micro-environments the measurement and characterization of motor vehicle emissions the use and development of emission receptor and dispersion models to arrive at quantitative relations between emissions and urban air quality.
9 Collaborative Research Environment Canada’s Environmental Technology Centre (ETC) in Ottawa: well equipped laboratories, state of the art research capability. Researchers in Environmental Engineering at Carleton University are collaborating with the Emissions Research and Measurement Division at ETC in applying experimental and modelling techniques in each of these areas.
