Newsom signs AB 14 to expand California whale protection program statewide, urging slower ship speeds to save blue whales and cut emissions

Governor Gavin Newsom signed AB 14 on Oct. 11, 2025, establishing the California Protecting Blue Whales and Blue Skies Program, expanding a voluntary vessel speed-reduction initiative statewide to protect blue whales, cut emissions and lower underwater noise.

  • Statewide program: AB 14 scales a proven local vessel speed reduction initiative across all California coastal waters.
  • 10-knot guidance: Ocean-going ships (typically 300 gross tons or greater) are encouraged to slow to 10 knots or less in designated lanes, earning incentives and recognition.
  • Measured benefits: Local pilots showed fewer whale strikes, major emissions reductions and quieter oceans.
  • Climate and public health co-benefits: The law aims to reduce greenhouse gases, NOx and toxic diesel particulate matter while protecting endangered whales.

What AB 14 does and how it builds on local programs

AB 14 creates the California Protecting Blue Whales and Blue Skies Program and gives state backing to efforts that began with local air districts in Santa Barbara and Ventura counties (2014) and the Bay Area (2017). Regional pilots encouraged voluntary slowdowns for ships in busy migration routes; the new law formalizes and scales those measures statewide. See reporting from Our Air and the Santa Barbara Independent for background.

Under AB 14, participating air pollution control districts and other authorities will promote and oversee a statewide vessel speed reduction initiative targeting vessels typically 300 gross tons or larger. The core request: ships slow to 10 knots or less in designated cooperative zones. Companies that comply will receive public recognition and other incentives designed to reward conservation-minded behavior (see TrackBill summary and Our Air).

Why slowing down helps whales, people and the climate

Officials and scientists point to three linked benefits:

  • Fewer ship strikes: Lower speeds reduce the chance that large vessels will fatally strike blue whales and other cetaceans.
  • Cleaner air: Ships burning less fuel at slower speeds emit fewer greenhouse gases and toxic pollutants, improving air quality for coastal communities.
  • Quieter oceans: Reduced speeds cut underwater noise, protecting whale communication, feeding and navigation.

Local pilots reported measurable outcomes: whale strikes fell by roughly half; fleet compliance in embraced areas is estimated at about 85 percent. Pilots recorded estimated avoidance of more than 200,000 metric tons of greenhouse gases, reductions of about 5,900 tons of NOx and 35 tons of toxic diesel particulate matter, and an estimated 38% decline in underwater noise where ships slowed. See Our Air and the Santa Barbara Independent for pilot data.

History and urgency: why California acted

Interest in stronger protections followed a series of deadly ship strikes in the Santa Barbara Channel, including five blue whales killed by vessel collisions in 2007. That channel is both a Whale Heritage Area and a major migration route, but it also carries heavy international shipping traffic, producing collision risk that local conservationists and scientists argued needed management (see Edhat coverage and Santa Barbara Independent).

“AB 14 is a rare win for both conservation and public health,” supporters said, highlighting the role of public-private cooperation and incentive-based measures.

Stakeholders, co-authors and celebrations

Assemblymember Gregg Hart authored AB 14 and celebrated the signing at Santa Barbara’s Stearns Wharf and the Sea Center, joined by coastal partners; watch the public celebration video. The bill was co-authored by Assemblymembers Steve Bennett and Damon Connolly and drew support from environmental groups such as the Environmental Defense Center, air quality officials and marine scientists (Our Air; KSBY; Santa Barbara Independent).

Advocates emphasize that the incentive-based approach rewards carriers that change operations rather than punishes those that do not, while giving air districts a role in organizing and tracking participation (Our Air).

Implementation questions and the role of monitoring

AB 14 keeps the program cooperative and voluntary, which raises practical implementation questions: How will districts identify the coastal shipping lanes where the 10-knot guidance applies? How will participation be tracked and verified? What incentives will most effectively encourage long-distance carriers to slow while in U.S. waters?

The bill assigns oversight to participating air pollution control districts and authorities, but detailed regulations and monitoring plans will be developed during rollout. For the bill text and legislative details, consult the LegiScan full text and the TrackBill summary.

AB 14 and broader climate and conservation goals

Beyond whale safety, proponents highlight co-benefits for climate and public health. Earlier program iterations avoided hundreds of thousands of metric tons of greenhouse gases and reduced pollutants that contribute to smog and respiratory illness in coastal and downwind communities. Lawmakers framed AB 14 as a policy that addresses biodiversity and air quality together (Our Air; Edhat).

Implications for the Inland Empire

Economic impact: The Inland Empire is inland from ports and coastal shipping lanes but tied to the state’s logistics and goods movement economy. Slower ship speeds could modestly shift freight scheduling at major ports (Los Angeles, Long Beach), with minor ripple effects for warehouses, distributors and truckers. Given the program’s voluntary, incentive-based design and high pilot compliance, major disruptions are not expected; primary effects are likely modest improvements in air quality for downwind communities (Our Air).

Political and social effects: AB 14 offers a politically moderate model pairing voluntary business incentives with public benefits—an approach that may appeal to Inland Empire leaders balancing economic growth and health priorities. Socially, reduced coastal shipping emissions can have downstream respiratory health benefits for Inland Empire residents when coastal pollution is carried inland (Santa Barbara Independent).

Practical applications: Employers and workforce planners should maintain dialogue with port operators, trucking companies and logistics firms about potential scheduling shifts. Public health officials and local air districts may use emissions data from the program to refine regional air quality planning and outreach (TrackBill).
