Excerpt:Joy Williams of the Environmental Health Coalition, an environmental justice group that has confronted the unjust consequences of toxic pollution, discriminatory land use, and unsustainable energy policies in the San Diego and Tijuana region for over 38 years, explained the importance of electrifying trucks and buses in comments to the Public Utilities Commission. “We believe that electrification of San Diego’s medium and heavy duty trucks and buses is crucial for reducing exposure to diesel exhaust of San Diego’s most vulnerable communities,” Ms. Williams stated. “Communities near the Port of San Diego and the border ports of entry are particularly key in this effort.”
