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

These challenges often involve the opinions of public, industry, and government stakeholders who seek Tetra Tech's advice on complex issues. We have helped thousands of towns, cities, industries, and governments find sustainable solutions to complex issues concerning resource management and infrastructure.

To provide solutions to these challenges, we believe in maintaining our technical objectivity. We have earned our reputation for technical objectivity over nearly five decades.

We have designed progressive, green buildings in New York city, helped the U.S. Department of Defense with pollution prevention and clean-up, and helped many Fortune 500 companies balance environmental needs with business goals. We are helping Vancouver achieve its goal of becoming the greenest city in the world. 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 nonprofit agencies and projects within their local communities.

As a sponsor of the nonprofit humanitarian organizations Engineers Without Borders USA and Engineers Without Borders Canada, Tetra Tech is committed to helping communities in developing countries meet their basic human needs through lasting, scalable projects and technologies.
