ESG is now a valuation factor, here’s how to address it

The ESG bar is rising. Regulatory pressure and stakeholder expectations are accelerating, and ESG can no longer be treated as an afterthought.

Today, ESG risks are valuation risks: from carbon liabilities and compliance gaps to reputational fallout that directly impacts enterprise value. Yet ESG, when done right, is more than risk mitigation; it becomes a lever for operational excellence, supply chain resilience, and long-term strategic positioning.

We help investors and portfolio companies gain clarity on both sides of the equation — risk and opportunity.

Frequently asked questions

Everything you need to know about our ESG Due Diligence & assessment

ESG due diligence is a structured assessment of a target company’s environmental, social, and governance practices during a transaction process. It identifies material ESG risks, compliance gaps, and value creation opportunities that may affect valuation, integration, or long-term performance.

ESG factors are increasingly tied to financial outcomes, from regulatory penalties and reputational damage to missed operational synergies. ESG due diligence helps buyers and sellers mitigate risk, justify valuations, and build a stronger equity story.

In addition to applying a sector-specific approach, we combine qualitative assessments with data-driven analysis to provide decision-ready insights. With our dedicated business unit ESGvolution, we evaluate ESG maturity across different areas to flag risks and highlight levers that enhance value creation. We also integrate ESG analysis with other due diligence streams (commercial, digital, tech, etc.) to provide a holistic view.

Yes, ESG issues impact every sector, though the material factors differ. In industrials, for example, carbon intensity, waste, and health & safety are key. In B2B tech, the focus often lies on often data governance, digital ethics, or Diversity, Equity and Inclusion (DE&I). Our sector-specific approach ensures relevance, not one-size-fits-all checklists.

Both. While identifying ESG risks is critical for protecting value, we also highlight where ESG can create value — through cost efficiencies, premium positioning, talent retention, and improved buyer appeal at exit.

Absolutely. ESG is most powerful when assessed alongside commercial, tech, digital, and operational due diligence. We coordinate workstreams to reduce redundancies, surface cross-functional risks, and align recommendations across the entire transaction.

Yes. We reference and benchmarks against relevant regulatory and investor frameworks, depending on geography, industry, and deal type. For EU deals, CSRD and SFDR are often front and center. For others, we may use GRI or UN PRI as a baseline.
