Public Workshop: Evaluating New Health Endpoints for Use in CARB’s Health Analyses

en español

As discussed in the April 2020 Board Hearing, CARB plans to evaluate new and updated methods to analyze and quantify the broader health benefits of air quality regulations, plans, and programs. This workshop will focus on evaluating additional health endpoints beyond those analyzed in our current methodology to reflect the latest science. CARB’s current approach focuses on quantification of a small subset of mortality and morbidity outcomes to analyze health benefits. However, the body of research on air pollution's health effects has grown substantially in the last ten years, and CARB’s health analysis needs to be updated to reflect the advances in scientific knowledge. 

In response to new research, the board directed staff, in Resolution 20-13, to update and expand health analysis tools, pollutants, and health endpoints to capture a broader and more comprehensive range of benefits from reductions in air pollution. This workshop will discuss updated and additional proposed endpoints for PM2.5 as well as ongoing projects, such as current research, that implements this board direction.

At this workshop, staff will provide an overview of the proposed plan to evaluate and update the health endpoints currently used, present the proposed additions for new health endpoints, and discuss the rationale for their inclusion in CARB’s methods for health analyses. Participants will have an opportunity to learn about the plan and comment on the proposed endpoints.

The workshop will be held virtually, with Spanish translation, at the following date and time:

Date:       Monday, December 6, 2021
Time:       2:00 pm – 4:00 pm (Pacific Time)


After registering, you will receive a confirmation email with information about how to access the webinar by computer or by telephone. This workshop will be recorded.

Tribal Participation

In recognition of the important government-to-government relationship California has with Tribes, CARB looks forward to the participation of California Native American Tribes in this workshop. CARB also looks forward to directly engaging with Tribes, including through any request for consultation. CARB’s Tribal Relations webpage provides additional information regarding CARB’s work with Tribes as well as contact information for CARB’s Tribal Liaison.


Currently, CARB routinely analyzes four mortality and morbidity health endpoints. Those endpoints are premature cardiopulmonary mortality, hospital admissions for cardiovascular illness, hospital admissions for respiratory illnesses, and emergency room visits for asthma attacks. While these endpoints represent important health outcomes experienced by the public due to air pollution exposures, there are updated or additional mortality and morbidity outcomes not currently considered that impact the public and lead to societal and economic impacts including hospitalizations, emergency room visits, missed work and school days, and other burdens.

CARB has launched a project in line with Board direction in April 2020 (Board Resolution 20-13: Health Evaluation of Air Quality and Climate Regulations and Programs) to update and enhance the agency’s ability to analyze a broader, more comprehensive set of health benefits of air pollution reductions.  As part of CARB’s ongoing commitment to evaluate and update the agency’s work with the latest science, staff plans to evaluate and propose inclusion of updated and additional health endpoints associated with criteria pollutants that are consistent with peer-reviewed scientific evidence, including information in US EPA’s 2019 Integrated Science Assessment for Particulate Matter and US EPA’s 2021 Technical Support Document for the Final Revised Cross-State Air Pollution Rule Update for the 2008 Ozone Season NAAQS.

Special Accommodation Request

This workshop will also include a Spanish participation option, and it will be recorded. CARB staff will be available to follow up with anybody that has questions after the workshop. If you require a special accommodation or need this document in an alternate format (e.g., Braille, large print) or another language, please contact Hye-Youn Park by email at no later than 10 business days before the scheduled meeting. TTY/TDD/Speech to Speech users may dial 711 for the California Relay Service.
