December 11, 2020 – SAN DIEGO, CA – Today, the Port of San Diego delayed approval of a massive project for Mitsubishi Cement Corporation (MCC) that would increase air pollution and greenhouse gas emissions by adding up to 8,700 new diesel heavy duty trucks to Portside communities. Demands to require Mitsubishi Corporation to use clean Zero Emission electric trucks that reduce diesel air pollution to protect portside communities from continued exposures to air pollution were heeded.

Environmental Health Coalition, community residents and a growing alliance of local, state and national organizations demanded that the Port of San Diego protect the air quality and health of San Diego residents. The Port has a significant opportunity to demonstrate leadership but staff proposed a zero emission (ZE) strategy that was essentially meaningless. The only requirement is ONE demonstration electric truck, and no other measurable requirements ‘unless and until’ the Port determines that zero emission vehicle (ZEV) trucks are feasible for the project. Criteria for a finding of feasibility is not included in the proposal therefore a requirement for ZEV trucks under this strategy would likely never occur.

Vice Chair Michael Zucchet expressed support for the Mitsubishi project but not at the expense of public health. “MCC is a great addition to the Port except for one thing – the benefits all come at the expense of the community health.” Zucchet made the motion to continue the item until a proposal with specific requirements can be crafted. The motion was approved unanimously.


The impacted communities of Barrio Logan and National City already rank in the top 5% for diesel air pollution in the state. Children’s asthma hospitalization rates are 3 times more than the county average in Barrio Logan and National City where COVID-19 infection rates are disproportionately high. COVID-19 is worse for communities with poor air quality.

COVID 19 is disproportionately affecting Brown, Black and Indigenous communities. In San Diego, Latinos account for about 34% of the population, but more than 60% of the COVID-19 cases, and County data shows a more than double rate of the virus in communities adjacent to the Port.

There is a 15% higher rate of COVID-19 mortality for communities with poor air quality and that are directly impacted from high fossil fuel emissions, like Portside communities with high diesel emissions.
