SIZING THE U.S. AND CALIFORNIA HARBOR CRAFT MARKET March 2024
Ports are a major source of greenhouse gas emissions and air pollution. This unfortunately leads to elevated levels of air pollution in the surrounding communities, which has negative impacts on public health. Marine vessels, many of which burn marine diesel oil, are responsible for a large portion of these emissions. In promoting the overall goal of creating cleaner air and lower greenhouse gas emissions, it is clear that commercial harbor craft and inland and nearshore vessels represent an important sector—and one that has begun to move to zero-emission operations. To support this transition, CALSTART, in partnership with Intelatus Global Partners, developed the Sizing the U.S. and California Harbor Craft Market report. This work is an inventory of commercial harbor craft and inland and nearshore vessel fleets above 600 kilowatts (kW) or 805 brake horsepower. This inventory helps us understand the size of the potential market for zero-emission harbor craft and identifies the vessels that are most suitable for transitioning to zero-emission
technology. This report is funded in part by the Clean Off-Road Equipment Voucher Incentive Project (CORE). CORE is part of California Climate Investments, a statewide initiative that puts billions of Cap-andTrade dollars to work reducing greenhouse gas emissions, strengthening the economy, and improving public health and the environment—particularly in disadvantaged communities. In this work, vessels were classified according to their suitability for zero-emission operations, and the commercial harbor craft market was classified into service categories including crew and supply boats, ferries and excursion vessels, fishing vessels, pilot vessels, tugboats, towboats, workboats, and other vessels. Based on this framework, the project team identified approximately 10,000 harbor craft above 600 kW in the United States, with 4,405 vessels being considered as highly suitable for zero-emission technology. California has 676 registered harbor craft, with 244 being identified as highly suitable for zero-emission technology.
Ten states contain 73 percent of harbor craft deployed in the United States: 6. Massachusetts 1. Alaska 7. Missouri 2. California 3. Delaware 8. New York 9. Texas 4. Florida 5. Louisiana
10. Washington
Louisiana is the single largest state for harbor craft, with approximately one-third of U.S. harbor craft registrations—this reflects the concentration of harbor craft in the Mississippi River system and the Gulf of Mexico ports.
