Tetra Tech  has long focused on helping our clients address water, natural resources, environment, infrastructure and, more recently, renewable energy needs.  We lead and support programs that minimize our collective impacts on the environment—through the solutions we provide for our clients; through our procurement and subcontracting practices; and by the processes we use within the company to promote sustainable practices, reduce costs, and minimize environmental impacts.

Our vision of the future is to more fully incorporate the concepts of sustainability into our daily operations and to "meet the needs of the present without compromising the ability of future generations to meet their own needs,” as proposed by the United Nations World Commission on Environment and Development. Tetra Tech is in a unique position to further this vision, and has the ability to provide innovative solutions to meet pressing global challenges.  On a daily basis and on a global scale, our work plays a direct role in helping to achieve the balance that will allow future generations to access the necessary resources to meet all of their needs.

The focus of Tetra Tech’s Sustainability Program is to continue sustained growth of our business, reduce greenhouse gas (GHG) emissions, and provide an exceptional work environment for our associates, all while providing better solutions for our clients.
