California Air Resources Board

California has collaborated for many years with partners in Mexico and the border region on air quality. These kinds of collaborations are critical, as harmful emissions do not stop at the border. In 2018, as part of CARB's State Implementation Planning work in the Salton Sea Air Basin, CARB focused efforts in the Imperial - Mexicali region. Some of those efforts are archived here.
