As discussed in the Methodology section, Tetra Tech organizes our sustainability indicators around the "3P" approach that has been fully ingrained in Tetra Tech's culture and business model. Triple bottom line analysis—incorporating environmental, economic, and social impacts—will be a core component of Tetra Tech's corporate sustainability reporting. These impacts will be analyzed according to the projects, procurement, and processes.
Each area of our 3P approach will be analyzed against the following indicators:
- Environmental performance, including energy efficiency, recycling, renewable energy, and emission reductions.
- Economic performance, including benefits to our clients and shareholders and operational efficiency.
- Social performance, including beneficial social project results, shareholder benefits, community outreach, workforce enhancements, and health and safety metrics.
- Integrated performance indicators yielding double or triple bottom line results.
Enterprise-Wide Performance Indicators
Tetra Tech uses the following metrics as indicators of our overall economic, environmental, and social sustainability:
- Revenue Growth – as documented in the company's annual report
- Headcount Growth – as documented in the company's annual report
- Carbon Emission Reductions – normalized per associate
