Protecting Blue Whales and Blue Skies is a voluntary Vessel Speed Reduction (VSR) Program along the coast of California. By creating seasonal and predictable slow speed zones, this program helps companies protect endangered whales, reduce fuel use and regional greenhouse gas emissions, and improve air quality. The Protecting Blue Whales and Blue Skies team independently verifies cooperation rates, quantifies the benefits of participation, and provides recognition of program participants to encourage the adoption of sustainable shipping practices across the globe.


Learn more about vessel speed reduction, program participants, and how and where the Protecting Blue Whales and Blue Skies Program operates.


See how the program has reduced regional greenhouse gas emissions, pollution, fatal ship strikes to endangered whales, and underwater noise since 2014.


The program collaborates with shipping carriers, retail brands, ports, and numerous other partners to improve shipping sustainability.  Learn how your company can join.
