Maritime Sustainable Century Awards
Environmental Performance Award – Alaska Marine Lines reduced diesel fuel use and air emissions by 75% and increased use of local clean electricity through high efficiency transport refrigeration units and timeshare electric panels. Energy reductions in 2023 amounted to over 1 million gallons of diesel, which equals nearly 11,000 (10,701) metric tons of carbon dioxide–equivalent emissions. This level of greenhouse gas reductions is equivalent to taking 2,547 gas-powered cars off the road or the energy use of 1,396 homes annually.
“Our entire team continually focuses on opportunities for innovation and efficiency,” said Jason Jansen, President of Alaska Marine Lines. “This award is only possible because of the dedication of our people, and I am extremely proud of their achievement.”
Environmental Innovation and Equity, Diversity & Inclusion Awards – The Muckleshoot Indian Tribe’s Fish Commission improved sockeye salmon survival in the Lake Washington migration corridor through the Ballard Locks Adult Sockeye Transport (BLAST) program. Since 2021, salmon pre-spawn mortality has dropped from 80% for salmon in natural transit to 1% for those transported to a hatchery in Issaquah via BLAST. BLAST is an innovative program that allows transported fish to avoid the heat, disease, and other hazards of the Lake Washington watershed.
“Salmon are part of our culture and a way of life for many Native communities. This award symbolizes a successful example of regional collaboration,” said LeeRoy Courville, Jr., Tribal Council member and Chair, Fisheries Commission, Muckleshoot Indian Tribe. “Because of increased urbanization, predation, and rising water temperatures, the Lake Washington sockeye are in danger of extinction. It is essential to commit the necessary resources in hatchery production and operations to ensure survival of the Lake Washington sockeye now and for future generations.”
Environmental Education and Outreach Award – Quiet Sound’s collaborative effort reduced underwater noise by 45% with voluntary commercial vessel slowdowns through the Admiralty Inlet corridor in Puget Sound between Whidbey Island and the Olympic Peninsula. Underwater noise is a key concern for Southern Resident killer whales, in addition to reduced Chinook salmon populations and poor water quality. By working across private and public sectors, 70% of vessels decreased their speed during an 80-day slowdown with minimal maritime trade and no safety impacts.
“Quiet Sound’s voluntary initiatives are making significant and measurable strides in reducing underwater noise in the critical habitat of the endangered Southern Resident killer whales,” said Rachel Aronson, Quiet Sound Director at Washington Maritime Blue. “We’re so thankful to the many hands that have helped shape and implement this program since 2021, including the Port of Seattle. Quiet Sound is honored to receive this recognition on behalf of our coalition of members and continue ensuring that the Southern Resident killer whales and our region’s blue economy thrive together in Washington waters.”
Environmental Innovation Award – Small Business – Stormwater Controls invented and manufactures the Retain Drain in the Pacific Northwest. This system uses coconut coir filters (a renewable resource) in a high-quality metal frame to remove litter and other contaminants from stormwater before it enters the Salish Sea. Stormwater Controls data show as much as 95% reduction of organic matter, solids, and trash in stormwater after it passes through Retain Drain.
“Winning the Environmental Innovation Award is a significant achievement for Stormwater Controls,” said Ken Perry, Managing Director of Stormwater Controls. “It signifies that we've surpassed regulatory requirements and demonstrated an exceptional commitment to improving our local waterways. By continuing to think outside the box, we will inspire businesses to elevate their practices while saving money and ultimately creating a healthier environment. At Stormwater Controls, EVERYTHING WINS!”
