Environmental Due Diligence

Blurred image of people walking through a modern urban plaza with greenery and glass buildings.

With every investment, it is critical to quickly identify risks and opportunities. Tetra Tech’s environmental due diligence experts provide commercially reliable solutions to mitigate risks involving finance, reputation, and reduced asset value.

We provide environmental due diligence assessments solutions to numerous private and public agencies, global multilateral funders, and private equity funds, ranging from environmental and climate change issues to land and corporate transactions worldwide.

Partnering with in-house asset and facilities management specialists and engineers, we simplify complex concepts into clear commercial terms to help assess impact on CAPEX and operational costs. We help create climate-resilient investments that account for resource security (energy and water), potential flood damage, and reputational risks.

Our post-transaction services range from input to the 100-day plan, to liability reduction and business integration, while our social economic advisory team evaluates Environmental Social Governance (ESG) and sustainability performance.
