EDMONTON, Alberta and NEW YORK, April 21, 2026 (GLOBE NEWSWIRE) -- TSX, NYSE:STN

Stantec, a global leader in sustainable design and engineering, released its 19th annual Sustainability Report, showcasing how sustainability is integrated into the Company's strategy, growth, and operations. The report details Stantec's sustainability practices, contributions, and accomplishments for the year ending December 31, 2025.

The firm's 2025 sustainability milestones include:

C$5.5 billion in revenue from work that supports the United Nations' core Sustainable Development Goals, representing 68 percent of total gross revenue. This reflects steady growth since the Company began tracking this work in 2019, when it represented 43 percent of total gross revenue.
Global operational carbon neutrality achieved for the fourth consecutive year, with continued progress toward net zero emissions under Canada's Net Zero Challenge, an effort to help the country move toward a cleaner economy
Recognition by the Carbon Disclosure Project, earning an A- score for the eighth straight year for demonstrating consistent climate action

"The choices we make today shape communities, economies, and the environment of tomorrow," said Gord Johnston, president and chief executive officer of Stantec. "This is why sustainability is embedded into everything we do—guiding how we live, move, work, and connect. By putting people first, we're helping create a more resilient and sustainable environment where communities can thrive for generations to come."

The report also brings Stantec's impact to life through projects that demonstrate how sustainability translates into real-world outcomes:

Canada: Advancing cleaner, smarter manufacturing, Stantec supported Duravit's new facility in Québec—one of the world's first carbon-neutral manufacturing facilities in the hygienic ceramic industry. Stantec's building engineering services enabled hydro-powered electric kilns, reducing emissions by nearly 9,000 tonnes of carbon dioxide equivalent annually.
United States: In the Klamath Basin of Oregon and California, one of the nation's largest restoration efforts is revitalizing ecosystems and reconnecting communities. Working alongside Indigenous Nations and local partners, Stantec's engineers and ecologists are restoring five fish-bearing tributaries, nearly 3.4 miles (5.5 kilometers) of stream channel, 2,200 acres (890 hectares) of native vegetation, and more than 400 miles (644 kilometers) of salmon habitat.
United Kingdom: Supporting the transition to cleaner, more reliable energy, the Vyrnwy Frankton Grid Connection in Mid-Wales enables new wind-generated electricity to reach the national grid. Stantec contributed early planning and design for the overhead line, substation, and underground cable infrastructure.
New Zealand: Following severe flooding and landslides that damaged over 311 miles (500 kilometers) of roads, Stantec partnered with the Marlborough District Council to shape a future access survey. The study engaged more than 1,500 participants through workshops, hui (gatherings), surveys, webinars, and community events—ensuring local voices informed long-term resilience planning.
Egypt: Protecting freshwater resources and expanding access to sanitation, Stantec supported the design of eight wastewater treatment plants around Lake Qarun in the Fayoum region. The project aims to increase access to safe sanitation from 33 percent to 70 percent during the first phase, benefiting approximately 700,000 people while safeguarding the lake's ecosystem.
