Tetra Tech’s sustainability metrics are used to report, evaluate, and track our performance. By evaluating our contributions to sustainability, we have the opportunity to improve management, make our operations more efficient, and provide better long-term solutions for our clients—solutions that address critical global issues, environmental challenges, and the values important to our stakeholders.

In compiling our Sustainability Report Card, we measure our sustainability progress in core areas of company operations. Each metric corresponds with one or more performance indicator from the Global Reporting Initiative (GRI), the internationally predominant sustainability reporting protocol for corporate sustainability plans. The indicators reported apply to our business in a meaningful way and represent ongoing activities related to Tetra Tech’s projects, business practices, and community engagement.

To track our progress and improvements, we established a current score or progress estimate for each target. Some metrics are tracked by fiscal year while others are tracked by calendar year, as specifically noted below. The scores are updated annually to reflect our sustainability progress and achievements.

Visit our Sustainability Performance Indicators page to learn more about how these metrics correspond to economic, environmental, and social responsibility.

Tetra Tech's Sustainability Report Card provides an overview of our sustainability performance, but cannot be inclusive of the full range of our employees' sustainability activities around the world. To see selected examples of sustainability initiatives across Tetra Tech, please visit our Sustainability Achievements page.

In 2016 Tetra Tech developed its goals for 2020. In several cases, we have added new metrics or updated methods for measuring our progress towards meeting our goals.
