Session by Roel Nieuwenkamp, Chair, OECD Working Party on Responsible Business Conduct This year marks the 40th anniversary of the OECD Guidelines for Multinational Enterprises, the most comprehensive set of recommendations and leading global standard on Responsible Business Conduct (RBC). The Guidelines are unique in that they remain the only government-backed international instrument on RBC with a built-in grievance mechanism that enables stakeholders – trade unions, NGOs, local communities – to raise concerns to National Contact Points (NCPs) in cases where the Guidelines are not observed. NCPs are located in 34 OECD countries and 12 non-OECD countries, actively promoting the Guidelines, handling enquiries, and contributing to the resolution of issues arising from alleged non-observance. As the role of business in society has evolved from the charitable and voluntary endeavours associated with corporate social responsibly to the more stringent expectations of RBC, MNEs are well-placed to take an active leadership role in addressing global social, environmental, developmental and human rights challenges. Since 2011, the Guidelines have included corporate supply chain responsibility and a number of countries have implemented legislation holding businesses accountable for carrying out the necessary due diligence to identify, prevent and mitigate real and potential adverse impacts related to their business operations or relationships, and for how they are addressed. In some countries, improving RBC standards of due diligence extends to human rights requirements, such as reporting sourcing from conflict areas and processes to manage the risks of human trafficking or forced labour.
