  1. Comparative Assessment of Road Transport Emission Inventories in Five Metropolitan Areas of South America Maria de Fatima Andrade, Eduardo Behrentz, Laura Dawidowski, Laura Gallardo Klenner, Dario Gomez, Mauricio Osses Open Conference of the Global Emissions Inventory Activity Project Paris, France November 29 - December 1, 2006

  3. Bogotá Santiago São Paulo M-cities gather problems and increase vulnerability from health issues to climate change

  4. Overview • IAI-SGPII: UMESAM-2004 (5 cities) • Establish an international network of scientists • Provide a common and comparable methodology that can be readily applied in SA • IAI-CRNII: SAEMC-2006-2010 (+ Mexico) • Provide accurate regional emissions and climate change scenarios for SA • Establish the basis for operational chemical weather forecast for SA cities. • ISSRC-IVE Model: 2001-2006 • 6 LA cities + 7 worldwide cities

  5. IVE Phase I: Vehicle Activity

  6. IVE Phase II: On-road Emissions

  7. RESULTS FOR BOGOTA

  8. Local Context

  9. PM10

  10. Why do we Focused on Mobile Sources? • Mobile sources represent a major fraction of the inventory - about 50% accounting for primary and secondary particulate matter. • From an exposure assessment perspective, mobile sources are more important than other sources.

  11. RESEARCH QUESTIONS - IN BOGOTA - • What is the contribution to total emissions by the different vehicle categories of the fleet? • Which are the most efficient measures to reduce vehicle emissions in the city?

  12. Bogotá's Vehicle Fleet

  13. Passenger Cars Taxis Transit buses Motorcycles Heavy-duty trucks Total Vehicle Activity and Pollutant Emissions in Bogotá

  14. The problem is the diesel quality

  15. Inter-city Comparison

  16. Active Fleet Composition

  17. Vehicle Technology

  18. Conclusions • Reliable information regarding emissions in cities from LA as well as from other places of the developing world can now be found and used to better understand the impacts of mobile sources. • This information will serve policy makers and will eventually translate into better fleet technologies, improved traffic management, and the introduction of fuel quality regulations.
