Research Summary:

California regulates air pollutants, including toxic air contaminants (TACs) such as diesel particulate matter, to protect public health and reduce serious human health risks such as cancer. CARB currently estimates reductions in cancer risks due to regulations that reduce toxic air pollutant emissions. However, CARB does not have a valuation methodology for cancer risk reductions associated with reduced exposure to air toxic pollutants.

The main objective of this research project is to develop a methodology to quantify and monetize cancer cases that are statistically estimated due to exposures to toxic air pollutants in California. The results of this project will allow CARB to better assess the quantitative benefits associated with cancer risk reduction through various airborne toxic control measures and policies. In addition, this project will help support CARB’s efforts to assess the effects of toxic air pollutants and understand the benefits of cancer risk reduction in priority communities, including low-income communities, and communities of color.
