Clean trucks in California ports: modelling emissions policy

The Port of Los Angeles (POLA) Clean Trucks Programme is a controversial environmental sustainability initiative adopted to restrict the use of drayage trucks hauling goods to and from port terminal operations. Pending litigation on the constitutionality of the programme, and proposed new legislation that would give the federal government and local authorities a greater role in curbing emissions from harbour trucking, it has important ramifications for the port and shipping sector. We review interactions between maritime ports and the enterprise and institutional interests connected with the current status of the initiative. We use a game theoretical model to anticipate the effects of potential truck conversion policies. Courts, legislators, and interest group advocates can use this knowledge to support proactive policies and create incentives for additional Clean Trucks Programmes.
