CAI-Asia Goals
The Clean Air Initiative promotes and
demonstrates innovative ways to improve the air
quality of Asian Cities through sharing
experiences and building partnerships
  • Sharing knowledge and experiences on air quality
    management
  • Capacity building
  • Improving policy and regulatory frameworks at the
    regional level
  • Assisting cities in formulating and implementing
    integrated air quality management systems
  • Piloting projects to encourage innovation

Creating an Air Quality Management Community in
Asia

  • 1/3 of world energy consumption is attributed to
    Asia
  • Since 2000, coal share in energy mix is
    increasing by 1 percent in lieu of oil
  • 57 of the increase from 2002 to 2003 energy use
    is attributed to China

    is located in China, but the demand for coal
    grows almost everywhere

    of Beijing and Hanoi
  • NO2 levels gradually increasing levels and just
    above the WHO guidelines
  • Almost all cities have been able to reduce levels
    of SPM and PM10 compared to the 90s level,
    however levels continue to remain above the
    guidelines except those of the more developed
    cities

Response Benchmarking AQM Capacity
Emissions estimates
Air quality measurement capacity
Data assessment and availability
Management enabling capabilities
Assesses the ambient air monitoring taking place
in a city and the accuracy and precision and
representativeness of the data collected
Assesses how air data is processed to value and
provide information in a decision-relevant
format. It also assesses the extent to which
there is access to air quality information and
data through different media
Asseses the administrative and legislative
framework through which emission control
strategies are introduced to manage air quality
Assesses emission inventories undertaken to
determine the extent to which decision-relevant
information is available about source pollution
in the city

Response AQ data analysis in Asia
  • Many cities have initiated development of
    Emission Inventories
  • BUT
  • Level of detail/ disaggregation varies greatly
  • Reliability of activity data on which
    inventories are based and Emission factors used
    is questionable for many of the cities
  • Inventories in many of the cases were conducted
    by outside groups academe or consulting firms
  • CAUTION
  • in formulating AQM policies based on current
    Emission Inventories

Response Ambient Air Quality Standards
Country Pollutants Remarks
Bangladesh TSP, CO, NOx, and SO2 1997 standards established for a few pollutants depending on land use category new standards are pending approval
China TSP, PM10, CO, SO2, NO2, Pb Standards require cities to comply with Class I, II, or III standards. Class I standards more stringent than the WHO and USEPA limits
Hong Kong TSP, PM10, CO, SO2, NO2, Pb, O3 Standards less stringent than WHO and USEPA limits
India TSP, PM10, CO, SO2, NO2, Pb Established based on different land-use categories i.e. industrial, residential and sensitive areas.
Indonesia TSP, PM10, CO, SO2, NO2, O3, Pb National and local (Jakarta) standards less stringent that WHO PM limits less stringent than USEPA
Japan CO, NO2, O3, SO2, TSP Comparable and to some extent more stringent than WHO guidelines with the exception of CO limits for an 8-hour exposure.
Nepal TSP, PM10, CO, SO2, NO2, Pb, C6H6 Established only in 2003 standards less stringent than WHO PM limits less stringent than USEPA
Pakistan No legislated ambient air quality standards
Philippines TSP, PM10, CO, SO2, NO2, O3, Pb based and comparable to WHO and USEPA (for PM10). Standards more lenient, selecting the higher/max allowable limits
Singapore PM10, CO, SO2, NO2, O3 Despite adopting only both WHO guidelines and USEPA limits, Singapore PSI reporting is very efficient
Sri-Lanka TSP, CO, SO2, NO2, O3, Pb TSP standards twice more lenient than USEPA, No annual standard for SO2, 24-hour limit for SO2, a slightly lenient O3 and NO2 compared with USEPA and WHO, respectively
Thailand TSP, PM10, CO, SO2, NO2, O3, Pb TSP twice more lenient than USEPA SO2 and CO almost same as USEPA limit, stringent NO2 compared to WHO
Vietnam TSP, CO, SO2, NO2, O3, Pb Hourly limits for NO2 and CO are more lenient than WHO, no PM10 standards, the rest of the standards are almost same as WHO
  • Most countries have more lenient standards than
    those prescribed by WHO and USEPA
  • Standards for PM10 have been largely based on
    USEPA limits
  • There is a need to review current PM standards,
    considering Europes move to 50µg/m3 limit for
    24-hour averages of PM10
  • Standards for other air toxics e.g benzene
    should be legislated
