ESG due diligence is a structured review of how a target company manages environmental, social, and governance risks — and whether those risks are material to value, financing, reputation, or post-close integration.
It is not a generic sustainability brochure exercise. For PE, corp dev, lenders, and family offices, ESG diligence answers: What can hurt us after we own this? What will LPs, banks, insurers, customers, or regulators ask? What remediation cost belongs in the model?
Cleanup liabilities, product liability, and governance failures become purchase-price adjustments or walk-aways.
Lenders and insurers increasingly underwrite climate, safety, and governance risk. Weak ESG can raise cost of capital.
Many limited partners require ESG screens on new investments. Process failure can block IC support.
Supply-chain labor issues, safety incidents, and culture problems can erode revenue or retention after close.
Site contamination, permits, emissions, waste, water, climate physical risk, product eco-impact, and transition risk for carbon-intensive models.
Workforce safety, labor practices, diversity of management, customer harm, community impact, human rights, and supply-chain labor exposure.
Board quality, ownership structure, related-party deals, ethics, anti-bribery, data privacy governance, audit culture, and whistleblower systems.
| Stage | ESG focus | Depth |
|---|---|---|
| Target screening | Sector materiality, public controversies, sanctions/news red flags | Light, hours per name |
| Pre-LOI | Known liabilities, permit status, major lawsuits, governance red flags | Public-info pack + management Qs |
| Confirmatory | Site reviews, policy testing, HR data, supplier audits, legal files | Specialists + data room |
| SPA / closing | Reps, indemnities, escrow for remediation, post-close action plan | Legal + ops integration |
| Approach | Typical cost | Turnaround | Best for |
|---|---|---|---|
| Big-4 / boutique ESG diligence | $25,000–$150,000+ | 2–6 weeks | High-risk sectors, financing-critical deals |
| Internal analyst + counsel | Loaded team cost | 1–4 weeks | Teams with ESG capacity |
| dodilligence first-pass report | $49 | 3–24s (median 15s · 4 real orders) | Public-info triage before specialist spend |
Use a cheap first pass to decide whether a name deserves a $50k specialist engagement — not to pretend the specialist is optional on contaminated sites or forced-labor exposure.
Traditional ESG diligence often runs $25K–$150K. A structured public-info first pass is $49 — enough to kill weak names early and sharpen questions for the survivors.
