Type of user: epidemiologist/analyst - takes raw data and provides decision support and aggregate data

Defines Societal Benefits: Societal benefits are calculated by aggregating individual net benefits across a population. Three basic approaches are used to value the utility gains or losses associated with a policy or a program—human capital approach; revealed preferences; and contingent valuation.

Emisions -> AQ -> Health/Environment Effects -> Monetary Value -> Aggregation across time and space

Issues with data

  • Selecting only one ambient air pollutant as the main pollutant may underestimate the magnitude of the health effects. Adding the health effect estimates of another air pollutant uncorrelated with PM (for example, ozone) can minimise the extent of this underestimation
  • Meta-analytic point estimates rather than estimates from one single study can enhance the value of the available information and deal with heterogeneity between studies.

Uncertainties: The following three factors contributed the greatest uncertainty in this analysis for the key air pollutants, nitrogen dioxide, PM10 and ozone:

  • Weather conditions in the future years;
  • Response of PM concentrations to changes in emissions of precursor gases; and
  • Source apportionment of PM.
