The Alan S. Lowenthal Blue Whales, Blue Skies Act directs the National Oceanic and Atmospheric Administration to establish a voluntary program encouraging large vessels to reduce their speed along the western U.S. coast. Ships that participate by traveling at 10 knots or slower would be eligible to receive annual Blue Whales and Blue Skies Excellence Awards and can display an official logo recognizing their participation, helping reduce air pollution, greenhouse gas emissions, underwater noise, and the risk of fatal whale strikes. The program, modeled after an existing voluntary effort already operating in California, must be established within 12 months and requires consultation with the Coast Guard and Environmental Protection Agency. Within four years, the administration must evaluate whether to expand the program along all Pacific shipping channels between Canada and Mexico and report its findings to Congress. Participation is entirely voluntary, requires no government funding or financial incentives, and does not affect maritime navigation safety requirements.
