An action plan to improve air quality in Dhaka, Bangladesh was developed under the ADB Urban Transport Environment Improvement Study in 2001 under the leadership of a committee of stakeholders. The primary objective of the action plan was to improve PM-10 and PM-2.5 air quality during the period 2002 to 2010 despite projected increases in annual emission growth. The additional benefits in reduced emission of other pollutants were of secondary importance.
The recommended action plan included a series of transport-related emission control measures included diesel fuel sulfur reduction, use of improved lube oils in 2-stroke engines, banning of 2-stroke 2-cycle "baby taxis" and replacement with new CNG-fueled vehicles, vehicle inspection programs and other measures. Emission reductions from each of the action plan elements and health-effect benefits of the combined strategy were then estimated by year and compared to projected control costs. A schedule for implementation was proposed. Results were then presented at a series of workshops to stakeholders. Several of the action plan components have already been implemented.
This paper describes how the action plan was developed using simple air quality management concepts that can be applied to other cities in Asia.
