CARB will propose new requirements for stricter in-use and new vessel requirements for both freight-related and passenger vessels. CARB will also:

  • Re-evaluate the feasibility of installing Tier 4 engine technology on in-use vessels;
  • Re-evaluate the feasibility of installing and performance of advanced retrofit emission control devices in Commercial Harbor Craft applications;
  • Re-evaluate stricter emission standards for marine engines, hybrid vessels, alternative fuel technologies.

CARB staff will further consider opportunities to prioritize the earliest implementation near the communities most affected by air pollution, and evaluate opportunities for incentivizing advanced technologies and/or early compliance.

In order to reduce shipping emissions, CARB staff will be visiting ports, analyzing vessel and engine activity, source testing vessels, and evaluating the feasibility of implementing newer engine, hybrid, alternative fuel, and retrofit technology.

It will also be collecting information to understand where Commercial Harbor Craft operate in Regulated California Waters, evaluate emissions, and identify and prioritize emission reduction strategies. CARB will also cooperate with communities to identify impacted areas and suggested strategies for effective control of air pollution from this source.

Currently, CARB is requesting information on any projects that showcase the use of successful technologies and approaches to limit emissions from Commercial Harbor Craft operations. Information and data on all of the following will be considered during the rulemaking process:

  • Demonstrations of hybrid, near-zero, and zero-emission equipment;
  • Charging/fueling infrastructure needs;
  • Development and application of aftermarket emission control devices;
  • Electronic engine records that can be used to update load factors in CARB’s emission inventory;
  • Vessel route(s) and location history data;
  • Industry operations and operational efficiencies to reduce emissions.
