Using ecosystem services to inform decisions on U.S. air quality standards

Area of Science:

• Environmental science
• Ecological economics
• Environmental policy

Background:

• The ecosystem services (ES) framework connects natural system changes to public welfare.
• Integrating ecology and economics enhances environmental decision-making transparency and public understanding.
• Valuation of nature's goods and services is key to this framework.

Purpose of the Study:

• Assess the utility of the ES framework for setting secondary National Ambient Air Quality Standards (NAAQS).
• Describe economic valuation methods for ES affected by NOx and SOx.
• Examine challenges and benefits of quantifying air pollutant effects on ES using a case study.

Main Methods:

• Policy analysis
• Systematic literature review
• Economic valuation techniques
• Case study analysis of secondary NOxSOx NAAQS review

Main Results:

• The ES framework offers a holistic approach, integrating environmental, ecological, and social factors.
• Economic valuation can summarize changes in ES impacted by air pollutants.
• Quantifying air pollutant effects on ES presents both advantages and challenges in decision-making.

Conclusions:

• The ES framework enhances environmental decision-making by providing a clear link between air quality and public welfare.
• Further development of quantitative linkages between ecosystem structure/function and ES will improve policy relevance.
• This approach promotes more consistent and transparent environmental policy development.
