Social Responsibility


At Tetra Tech, we seek clear sustainable solutions that improve the quality of life. We take this responsibility seriously because Tetra Tech's work often places us at the center of our clients' challenges regarding environment, safety, and sustainability.


These challenges often involve the opinions of many stakeholder groups from the public, industry, and government who seek Tetra Tech's advice on complex issues.

To provide solutions to these challenges, we believe in maintaining our technical objectivity.


We have earned our reputation for technical objectivity over the last four decades. We have helped thousands of towns, cities, industries, and governments find sustainable solutions to complex issues concerning resource management and infrastructure.


We have designed progressive "green" buildings in New York City, helped the Department of Defense with pollution prevention and clean-up, and helped many Fortune 500 companies balance environmental needs with business goals. Tetra Tech companies hold memberships with the U.S. Green Building Council, the Chicago Climate Exchange, and the U.S. Environmental Protection Agency's (EPA) Climate Leaders.


We also encourage our professionals to participate in outreach programs. Tetra Tech associates and offices participate in many non-profit agencies and projects within their local communities.


As a sponsor of the non-profit humanitarian organizations Engineers Without Borders USA and Engineers Without Borders Canada, Tetra Tech is committed to providing sustainable water, transportation, and housing systems to the developing communities that need them most.
