The UN Guiding Principles ask companies to know and show that they respect human rights through continuous due diligence, not a single audit. This checker turns that expectation into 30 concrete indicators across five pillars so procurement and ESG teams can benchmark where their process is strong and where it is exposed.
The five pillars covered
The assessment follows the UNGPs’ own structure, elaborated in the OECD Due Diligence Guidance for Responsible Business Conduct:
| Pillar | What it tests |
|---|---|
| Policy commitment | Public statement, board accountability, embedding in supplier contracts |
| Salient risk identification | Mapping, severity and likelihood prioritisation, supplier data |
| Integration and supplier action | Due diligence in procurement decisions, audit and improvement plans |
| Tracking and verification | KPIs, third-party verification, corrective-action follow-up |
| Grievance and remedy | Operational mechanism, access for affected parties, actual remedies provided |
How it works
Each indicator is answered Yes, Partial, or No and scored 2, 1, or 0. The maximum is 60 (30 × 2). A percentage of the maximum gives the overall maturity score, while each pillar is scored separately so weaknesses can be located precisely:
Yes = 2, Partial = 1, No = 0
maturity % = total score / (30 × 2) × 100
Bands map the percentage to a tier from Initial, where salient-risk exposure is high, up to Mature, where the process is robust and UNGP-aligned.
Worked example and common failure pattern
A company with a strong public policy and supplier code but no operational grievance mechanism will score well on the first three pillars and poorly on remedy, which the pillar breakdown exposes immediately. This is the most common gap in corporate HRDD programmes: identifying impacts without a route to remedy fails the UNGP test outright.
A second common pattern is a high score on Pillars 1 and 2 (policy exists, risks listed in a register) combined with a Partial-heavy Pillar 3 — the company has a code of conduct but has not integrated HRDD into purchasing decisions or supplier selection criteria. That gap means known risks are catalogued but not acted on, which regulators and investors now treat with increasing scepticism.
Regulatory context
The EU Corporate Sustainability Due Diligence Directive (CSDDD), adopted in 2024, translates many UNGP concepts into binding obligations for large companies operating in or supplying to the EU market. The UK Modern Slavery Act and the German Lieferkettensorgfaltspflichtengesetz (LkSG, in force since 2023) add further mandatory requirements in their respective jurisdictions. A high score on this checker indicates strong process maturity and a sound foundation for formal compliance — but legal obligations under each instrument must be assessed with qualified legal advisers, not self-assessed alone.
Treat the result as an internal benchmarking aid that points to the next investment, not as assurance or formal compliance evidence.
