On the 40th anniversary of Earth Day in 2010, Tetra Tech formalized our Sustainability Program to advance our environmental, social, and governance (ESG) goals through our projects, operations, and employee-supported charitable activities and volunteer work. Tetra Tech has long focused on providing our clients with industry-leading sustainable solutions that support development of safe water supplies, net zero energy programs, and biodiversity protection through habitat preservation and restoration.

Tetra Tech established a Sustainability Council to help coordinate and track our Sustainability Program, oversee development of an annual corporate Sustainability Report, and support communication of best practices across the Company. The Council is led by Tetra Tech President and Chief Sustainability Officer, Dr. Leslie Shoemaker.

Our Sustainability Program focuses on supporting Tetra Tech’s mission to be a premier worldwide consulting and engineering firm, focusing on water, environment, sustainable infrastructure, renewable energy, and international development.

We will achieve this mission by embracing sustainability in our business and operations while supporting the Company in delivering excellent services to our clients, maintaining superior financial performance, and emphasizing safety in the execution of our projects.

Our goal is to improve the lives of 1 billion people by 2030. Because our biggest impact on the world is through the projects we perform for our clients, we are tracking the total number of lives improved from our projects. We align our project impact analysis with the Global Reporting Initiative (GRI) standards and the UN Sustainable Development Goals (SDGs), which measure social benefit and aim to reduce poverty in communities around the world.

In addition to our 1 Billion People Challenge, we have expanded reporting of our operational greenhouse gas emissions to encompass Scope 1, 2, and 3 CO₂e emissions. We also are reporting new human capital metrics that align with our commitment to developing a thriving employee community, including gender balance, racial and ethnic diversity in our workforce, employee engagement, and professional development.
