The OECD Guidelines for Multinational Enterprises on Responsible Business Conduct (the Guidelines) are recommendations jointly addressed by governments to multinational enterprises to enhance the business contribution to sustainable development and address adverse impacts associated with business activities on people, planet, and society. The Guidelinesare supported by a unique implementation mechanism, the National Contact Points for Responsible Business Conduct (NCPs), established by governments to further the effectiveness of the Guidelines. Since their introduction in 1976, the Guidelines have been continuously updated to remain fit for purpose in light of societal challenges and the evolving context for international business. The 2023 update reflects a decade of experience since their last review in 2011 and responds to urgent social, environmental, and technological priorities facing societies and businesses.
