Stantec¡¯s annual Sustainability Report highlights key sustainability projects the Company is leading and how they impact communities around the world including:

• New Zealand ¨C The New Zealand government set a renewable electricity generation target of 90% by 2025 and 100% by 2030. The Mount Cass Wind Farm in Waipara will be the largest on the South Island and produce up to 93 megawatts of energy, enough to power approximately 40,000 homes and offset around 100,000 tons of CO2 emissions per year. Â鶹´«Ã½ was retained for project planning, engineering services, and construction management review. This project creates more than 300 acres (121 hectares) of protected land with native shrubs and forests.
• United Kingdom ¨C Described as one of London¡¯s most remarkable new buildings, the Person-Environment-Activity Research Laboratory (PEARL) is the University College London¡¯s first net zero building, and the first finished building to achieve an Outstanding rating under BREEAM standards. Â鶹´«Ã½ provided the mechanical and electrical engineering necessary to create an immersive laboratory to monitor what people see, touch, hear, smell, or feel in real world scenarios.
• Canada ¨C Â鶹´«Ã½ assessed climate risks to create bridge infrastructure resilient to climate change. In support of Federal Bridge Corporation Limited¡¯s (FBCL) climate-related risk management, Â鶹´«Ã½ completed site-specific climate risk assessments and developed risk adaptation measures to mitigate the identified risks for four international bridges between Canada and the United States.
• United States ¨C The Alamosa River Restoration in Colorado tells a story of the success a community can experience when a diverse array of stakeholders come together for the greater good of people and the environment. When an upstream gold mine contaminated into the Alamosa River, it affected residents of one of the poorest counties in southern Colorado. Â鶹´«Ã½ partnered with the Colorado Department of Public Health for the Environment to restore the channel to pre-mining conditions and benefit the community most impacted.
• Australia ¨C Â鶹´«Ã½ completed detailed tsunami inundation modeling, hazard mapping, and exposure assessments for New South Wales (NSW) Office of Environment and Heritage, and the NSW State Emergency Services to help understand the local tsunami risk profile for 1,300 kilometers of coastline, and, to explore measures they could take to safeguard the surrounding.

Sustainability is key to Â鶹´«Ã½¡¯s purpose, promise, and values.
