A variety of strategies to reduce greenhouse gas (GHG) emissions relate to marine sources including freight ships, passenger ferries, and recreational boats.
- Impacts of Speed Reductions on Vessel-Based Emissions for International Shipping (2009)
- Transportation Research Board
- Greenhouse gas emissions from international shipping are an increasing concern for those interested in mitigating global climate change. Reducing vessel speed represents one operational option for decreasing such emissions. In this paper, we evaluate whether speed reduction can be a potentially cost-effective measure for ships calling on U.S. ports.
- Multi-Partner Cooperative Research Agreement for Greenhouse Gas and Other Emission Reductions Aboard a Large Container Vessel (Ongoing)
- U.S. DOT Center for Climate Change
- This project funds a literature search and technology assessment and the physical survey of a container vessel in order to install and test various emission reduction systems aboard a vessel, that were previously installed in shore-side power plants. Phase II, consisting of the installation and testing of the systems, and Phase III, including the calculation of the resulting air emissions reductions, would be funded by other partners in this project.
- Passenger Ferries, Air Quality, and Greenhouse Gases: Can System Expansion Result in Fewer Emissions in the San Francisco Bay Area? (2002) (PDF 1.1mb)
- This study investigates the current emissions from ferries and examines the developing technological advancements for ferries to determine if they can be a viable environmentally-sound form of transportation.
- Stock Modeling for Railroad Locomotives and Marine Vessels (2004) (PDF 1.82mb)
- Volpe National Transportation Systems Center
- This report estimates the survival curves for locomotives and marine vessels to analyze the impact that new equipment will have on future energy emissions. This data will serve as a basis for developing stock turnover algorithms that could be incorporated into current or future energy and emissions models.
- Washington State Ferries Clean Fuels Initiative (2004)
- Washington State Ferries
- This program is an effort to shift the entire Washington State Ferries fleet of ferries to low-sulfur diesel fuel, test ultra-low sulfur diesel fuel, and test biodiesel fuel in an effort to improve air quality by reducing the amount of fuel exhaust emissions. In Summer 2007, EPA published an update on the Biodiesel Pilot Testing component of this project. (http://www.epa.gov/diesel/ports/documents/biodiesel-wash-state-ferries-071007.pdf (PDF 620kb))
