Project at a Glance

Title: Developing a Comprehensive Framework for Estimating the Social Costs of Emissions of Criteria Pollutants and Air Toxics in California, and Identifying Other Direct and Indirect Benefits of California's Climate and Air Quality Programs

Principal Investigator / Author(s): Delucchi, Mark

Contractor: UC Davis

Contract Number: 20RD007


Research Program Area: Atmospheric Processes, Climate Change

Topic Areas: Impacts, Modeling


Achieving California's challenging air quality and climate objectives will require accurate information about the health benefits (and avoided damages) of relevant policies. Metrics on the impact of policies on the health and well-being will make it easier for communities and decision-makers to understand and track the effect of aggressive climate and air quality policies and measures. The current Cost of Carbon metric is not sufficient to meet these needs and new metrics are needed to better quantify climate, air quality health, and other co-benefits of California's climate programs. This project will address that need by qualitatively assessing the environmental, energy, economic, and social benefits related to California's climate and air-quality programs. This project will estimate air-quality health benefits by developing a more comprehensive set of concentration-response functions, capturing the effects of socio-economic status, and including a detailed analysis of the impacts of the emissions of toxic air contaminants. This work will also include estimates of the agricultural and visibility benefits of improvements in air quality, ecosystem benefits, and incorporate the interaction of the nitrogen cycle with air quality. The project will produce a spreadsheet model that will account for all of the major factors that determine air-pollution damages. CARB staff will be able to use this model to evaluate the full social costs and benefits of its climate-change and air-quality programs.
