Tetra Tech’s 2020 Sustainability Report Card shares how we are using technology to enhance sustainability in our projects, operations, and communities around the world. With the best technical experts and the latest technology, we create cost-effective, sustainable solutions that are good for the environment and the community.

Tetra Tech’s commitment to sustainability began with the company’s founding and, more than 50 years later, we continue to provide clients with innovative solutions to complex water and environmental challenges. The sustainability principles we apply to our projects are described in our environmental, social, and governance (ESG) policies. As a member of the United Nations (UN) Global Compact, our business strategies and operations are aligned with universal principles on human rights, labor, environment, and anti-corruption. Tetra Tech’s ESG policies reflect these fundamental principles, including human rightsdiversity and inclusionprocurementenvironmenthealth and safety, and combating human trafficking. These policies are shared both internally with our employees and externally on tetratech.com/sustainability for Tetra Tech partners and vendors to join in our commitment.

From this foundation of sustainable and socially responsible operations, we look for opportunities to incorporate sustainability throughout our business.

We use the latest tools and technologies on every project we perform to advance sustainable outcomes, such as greater efficiencies in energy use, improved air and water quality, and communities resilient to the effects of climate change. 

In 2019 we worked on more than 70,000 projects that contributed to a healthy environment worldwide. We highlight several projects in this year’s report card for which we used technology to improve the quality of life for people and ecosystems—from designing an innovative water filtration process in Canada, to creating a monitoring and visualization platform to protect biodiversity and wildlife in Southeast Asia, to designing smarter, more sustainable buildings around the world. We indicate how each of the projects highlighted align with the UN Sustainable Development Goals.

We are continually expanding the beneficial impact of our sustainability practices throughout our global operations.Our commitment has resulted in significant progress towards meeting our five-year goals. We surpassed our 2020 goal of 50 percent CO2e emission reduction by achieving a 59 percent reduction since program. We use the latest tools and technologies on every project we perform to advance sustainable outcomes.

We reached our 2020 sustainability targets early for 11 metrics and improved in 20 of the 27 metrics we track. Included in these accomplishments are perfect safety records for 34 of our operating units and a strong focus on diversity-focused outreach. Tetra Tech incorporates sustainability not only in our projects and operations, but also in the communities we live and work in. In 2019 our associates made a difference in their local communities through 5,842 volunteer hours, fundraising of more than $469,015, and donations of goods and services. Our Science, Technology, Engineering, and Mathematics (STEM) Program has reached more than 10,000 people in 2019 and more than 30,000 people since 2016. Across our company, Tetra Tech maintains a long-standing relationship with Engineers Without Borders, providing financial and technical support to bring clean water to communities in developing countries.

While we achieved and even surpassed many of our sustainability targets this past year, we will continue to identify new targets and measures that will further our overarching sustainability goals. Tetra Tech is committed to incorporating sustainability practices and values throughout our global operations through our projects, our practices, and our communities.
