Vessel Speed Reduction for Ocean-going Vessels

This page last reviewed August 24, 2009

marine vessel Welcome to the Vessels Speed Reduction (VSR) webpage. As part of our efforts under the Diesel Risk Reduction Plan, Goods Movement Emissions Reduction Plan, and Assembly Bill 32 - Greenhouse Gas Initiative, the Air Resources Board (ARB) staff is evaluating the need to develop an ocean-going vessel (OGV) speed reduction program. Ocean-going vessel speed reductions offer the possibility for significant reductions in emissions of oxides of nitrogen (NOx), oxides of sulfur (SOx), diesel particulate matter (PM) and carbon dioxide (CO2). A VSR program or measure could be an important element in improving air quality along California's coastline communities.

This webpage provides access to documents presented at public meetings and shares information on ARB's activities regarding VSR. If you would like to be notified of news related to VSR, including workshop notices and other information, subscribe to the Vessel Speed Reduction List Serve.

ARB requests that you complete and return the Ocean-Going Vessel Speed Reduction Survey (Survey).  This Survey is designed for ship owners/operators (both U.S. and foreign-flagged) and charterers that visited a California port in 2007.  Your participation in this Survey will help us to determine the economic impacts that any VSR program or measure may have on the shipping industry.

All owners/operators of ocean-going vessels and charterers are required to complete the Survey.  State law authorizes the ARB to request and gather information required to determine if regulations are required to protect public health.  ARB is requesting you complete and return the Survey by January 30, 2009

Survey Cover Letter 414k
Survey Packet 890k 183k
