Transportation planning decisions can significantly impact people’s exposure to air pollution. Sustainable transportation strategies reduce community exposure by promoting zero emission technologies, facilitating active transportation (bicycling and walking), and improving access to public transit.

The below resources are designed to support development of sustainable transportation strategies through transportation policy and planning resources, strategy resources, tools and data, and research. This is not intended to be an exhaustive list, but a helpful starting point for those interested in air quality and transportation issues. This list will be refined and updated as new resources become available.

Some of the links below lead to non-CARB resources, but provide information that may be helpful to individuals interested in air quality and transportation. CARB cannot attest to the accuracy of these sites, and linking to a non-CARB site does not constitute an endorsement by CARB or any of its staff.
