Reducing the Risk of Ship Strikes to Endangered Whales
Reducing speeds saves whales. Our program proves that voluntary speed reductions significantly cut fatal strike risk, protecting endangered species while keeping global trade moving.

The Facts
Massive cargo ships carrying the products and goods we rely on transit through key whale feeding and migration areas.
Ship strikes are one of the main threats to endangered whales.
Research shows that ships traveling at 10 knots or less significantly reduces the risk of fatal ship strikes.
In 2024, BWBS enrolled shipping lines reduced the risk of fatal ship strikes to endangered whales by an estimated 50%.
One Strategy for Safer Whales
Whales aren’t the only giants in the ocean. Massive cargo ships carrying the products we purchase transit through whale feeding and migration areas on their way to and from ports along the U.S. West Coast. Ship strikes are one of the main threats to endangered whales. Research shows that ships traveling at 10 knots or less significantly reduces the risk of fatal ship strikes.

How We Measure Progress
Our scientifically validated risk reduction models are used to calculate ship strike risk reduction resulting from the program.
Verification Partners
The program works with third-party researchers and consultants to calculate the environmental benefits of participation.
