OECD Guidelines
The OECD Guidelines for Multinational Enterprises, together with the United Nations Guiding Principles for Business and Human Rights (UNGPs), form the framework for international Responsible Business Conduct (RBC). The guidelines also include the core labour standards of the International Labour Organization (ILO).
The process of due diligence is central to international RBC. In doing so, companies are expected to identify, prevent and mitigate the actual and possible negative impact of their actions and to account for how they deal with identified risks.
The OECD explains the guidelines in this short video.
