P:1 – Mandatory Human Rights Due Diligence NomoAdmin1 December 29, 2025

Mandatory Human Rights Due Diligence

Legal Obligations

Around the world, governments are turning voluntary “good practice” on human rights into legal obligations. Laws such as the Uyghur Forced Labor Prevention Act in the United States, new supply-chain due diligence laws in Europe, and transparency rules in Canada and elsewhere all rely on the same core idea: Human Rights Due Diligence (HRDD), the process companies use to identify, prevent and address how their operations, supply chains and investments affect people’s rights. By making HRDD mandatory, states are signalling that it is no longer enough to have a policy on paper—companies must be able to “know and show” that they are not profiting from abuse.

What Mandatory HRDD Looks Like in Practice
We help companies move from paper commitments to real-world checks on how their operations, suppliers and investments affect people.

End-to-End Human Rights Due Diligence

We work with companies to map their human rights risks, talk directly with workers and communities, and turn the findings into practical actions that reduce harm and improve outcomes for rightsholders.

Map the Risk

Screen operations, portfolios and suppliers to see where severe human rights risks are most likely, based on industry, geography and who is most vulnerable.

Assess Real-World Impacts

On high-risk sites we review documents, visit the field and speak with affected people to understand how rights are actually being affected on the ground.

Act, Track and Improve

We help clients design targeted fixes, set indicators, and monitor change so they can “know and show” that mandatory HRDD is preventing harm—not just ticking a box.
