Air quality: quality planning and analysis pdf analysis – GOV. This guide explains how impacts on air quality should be incorporated into a cost benefit analysis.

This guide explains how impacts on air quality should be incorporated into a cost benefit analysis. Air pollution harms human health and the environment. HM Treasury’s Green Book guidance provides the framework for economic appraisal and evaluation of all Central Government policies, programmes and projects. In line with its advice, you should reflect air quality impacts in decision-making wherever possible.

50 million and do not affect compliance will legal limits on air pollution then you can report the damage cost estimates. 50 million, consider a detailed abatement assessment. Damage costs are a simple way to value changes in air pollution. They estimate the cost to society of a change in emissions of different pollutants. Damage costs are provided by pollutant, source and location. Table 1 provides the most commonly used damage costs used to assess national policies, programmes and projects. This estimate is intended for use only where a single point estimate is necessary and should always be accompanied by the central range.

SOX and ammonia reflect uncertainties around the lag between exposure and the health impact. The sensitivity for NOX also reflects the uncertainty around the link between NO2 exposure and mortality. September 2015: The damage cost for NOX was updated on 12 September 2015 to reflect the latest evidence. The impact pathway approach is a more detailed way to value air quality changes. It estimates air pollution costs based on location-specific modelling of how changes in pollution affect air quality, but relies on standard estimates of impacts and their valuation. Proposals that change emissions in a way that affects compliance with legal obligations should use the abatement costs approach.

The abatement costs recognise that changes in emissions will affect the level, and cost, of action required to comply with such obligations. Where the proposal affects emissions in other locations, or below the limit, you should use the damage cost or impact pathway approach as appropriate. You will need to know the levels of pollution in relevant areas and the current legally binding air quality objectives. 2015, based on current policy. Unit abatement costs are available in the air quality supplementary guidance or the abatement cost guidance. You will need to consider in detail how your proposal changes the level of abatement action needed to offset your proposal’s impacts on legal obligations.
