Supplier & value-chain ESG assessment

Your ESG is only as strong as your value chain.

In short

Supplier and value-chain ESG assessment means assessing and engaging your suppliers against environmental, social and governance criteria, and building the Scope 3, due-diligence and disclosure evidence that buyers, regulators and rating agencies increasingly require of you.

What it is

Assessment and engagement of your suppliers on environmental, social and governance criteria — building the Scope 3, due-diligence and disclosure evidence that buyers, regulators and rating agencies increasingly require.

Why it matters

Most of a company’s emissions, and much of its regulatory and reputational risk, sit in its value chain. Value-chain data requests now reach far below regulatory thresholds — even where you’re out of direct scope, your buyers are not, and the requirement flows down.

Scope 3 vs operational emissions, on average

The scale of the value-chain gap is the point: supply-chain (Scope 3) emissions are on average around 26× a company’s operational emissions (CDP & Boston Consulting Group, 2024), and requests now cascade through BRSR value-chain rules and EcoVadis/CDP supplier questionnaires — reaching well below formal thresholds (OneStopESG, 2026).

What & how we do it

The work, in the order we do it.

  • Segment and risk-screen suppliers across E, S and G
  • Collect data and primary Scope 3 evidence to replace industry averages
  • Run supplier engagement and improvement plans
  • Build a traceable value-chain record aligned to your disclosure and procurement requirements

Standards & frameworks

  • Aligned to the GHG Protocol Scope 3 Standard
  • CSDDD-style due diligence
  • BRSR value-chain disclosure

Common questions

Because Scope 3, due diligence and buyer scorecards all depend on value-chain data you don’t hold until you collect it.

Primary supplier data replaces averages, for a more accurate, defensible footprint.
