New:  Community Forum on the trial program to reduce ship speed in the Santa Barbara Channel  "Protecting Blue Whales and Blue Skies" will be Wednesday, September 10, 2014, 3-5 pm at the Cabrillo Pavilion Arts Center in Santa Barbara. See flyer (alternate version for printing here).

Vessel Speed Reduction Incentive Trial Program for 2014 launched in the Santa Barbara Channel to reduce air pollution and protect whales is moving forward, working with partners Environmental Defense Center, NOAA Channel Islands National Marine Sanctuary, and the National Marine Sanctuary Foundation. See factsheet and map.

Additional Information

A September 2013 court decision will leave in place international rules to reduce shipping emissions. See this page for more information.

The District has suggested using AB 32 Cap-and-Trade auction funds to achieve voluntary ship speed reduction off the coast of California. This could reduce emissions of greenhouse gases and a range of other pollutants; it could also reduce the lethality of ship strikes on whales. On March 7, 2013, the District submitted a proposal for a vessel speed reduction incentive initiative to the California Air Resources Board, and on April 23, the District submitted a letter calling for inclusion of the initiative in the final Investment Plan. See April 23, 2013 letter, plus letters supporting the idea of a vessel speed reduction initiative from other agencies, businesses, and organizations. Also see original March 7 submittal with Implementation Plan The state FY 2013-2014 budget established that these funds would be loaned to the budget, and not expended in this fiscal year; the District is continuing to explore ways to implement this project.

The District has held a series of  Marine Shipping Solutions Group meetings. A November 8, 2012 meeting featured Bruce Anderson of Starcrest Consulting Group and Carter Atkins of the Port of Los Angeles. See presentation (PDF). See descriptions of previous meetings in the District newsletter featuring whale researcher John Calambokidis in the summer 2012 issue, and Lee Kindberg of Maersk in the winter 2012 issue.

Large ships are responsible for substantial amounts of worldwide emissions of black carbon, nitrogen oxides (NOx), particulate matter, sulfur, air toxics, greenhouse gases, and substances that deplete ozone in the upper atmosphere. Shipping emissions have been included in District emission inventories since 1994, and the District has been working to raise awareness of the problem and calling for voluntary and regulatory measures to control these emissions. In Santa Barbara County, NOx emissions from ships traveling off our coast are a concern, as NOx emissions are involved in the formation of ozone, and the County does not attain the state ozone standard. A continued focus on marine shipping emissions is also important to ensure the County remains in attainment of the federal ozone standard. The figure below (from the District's 2010 Clean Air Plan) illustrates the size of the problem.

See "Past Activities" link above to see past District activities calling for regulations in this area.Recently, several regulations have been issued that will reduce these emissions (see "Initiatives" link above). These regulations will bring about significant reductions in several pollutants in the near term, however, NOx reductions will only be achieved in a long-term timeframe. The District's current focus is to explore ways to achieve more near-term NOx reductions, and additional reductions in other pollutants. See "Local Studies & Actions" and "Technologies and Research" links above for more information.
