Overview l.jpg
Overview Inventories in Five Metropolitan Areas of South America

  • 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

Why do we focused on mobile sources l.jpg
Why do we Focused on Inventories in Five Metropolitan Areas of South AmericaMobile 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.


Research questions in bogota l.jpg
RESEARCH QUESTIONS Inventories in Five Metropolitan Areas of South America - 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?

Conclusions l.jpg
Conclusions Inventories in Five Metropolitan Areas of South America

  • 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.
