The club previously published news regarding the California Air Resources Board’s (CARB) new requirements back in September 2020 to control emissions whilst ships are ‘at berth’ in some Californian ports.

The ‘at berth’ regulations were first introduced in 2007 and required for a percentage of vessels to utilize shore power whilst in port, based on the type of vessel and the frequency of port calls.

The regulations were amended in 2020 and were expanded to include more vessel categories and terminals which came into effect on 1 January 2023.

The regulation applies to Vessel operators, terminal operators, ports, and third-party CARB-Approved Emissions Control Strategy (CAECS) operators.

Under the new regulations, emission reduction and reporting requirements have become stricter and the CARB now requires vessels to meet emission reduction and reporting requirements at California marine terminals by a specific deadline per below:

Compliance Start Date
