Background
PM main emission problem in Asia
CAI-Asia conducted DIESEL pilot project in
Bangkok

• The ultimate goals of the project are
• To gain a better understanding of factors
  affecting in-use diesel vehicle emissions.
• To assess alternative mitigation options to
  assist decision making in developing countries.

Developing Emission Reduction Strategy

• grid based emissions database for selection of
  options

• IDEAS database
• General Information geography, population
  Statistics, land use
• Sources industries, power plants, transport,
  domestic sectors, etc
• Energy Consumption Levels - fuel type, fuel
  characteristics
• House Hold Energy Consumption heating and
  cooking
• Traffic Volumes road network, location,
  traffic volume, vehicle number by age, and type,
  emission factors by type
• Emissions criteria pollutants
• Monitoring- historical and present
