The OECD Guidelines are part of the OECD Declaration on International Investment and Multinational Enterprises.
There are voluntary principles and standards for multinational and national enterprises that operate in their home countries or in the host countries. They also cover a wide range of supply chains, as part of the duty of the entreprise's due diligence.
They aim to promote responsible business conduct in accordance with national laws and international standards, in terms of publication of information, human rights, employment and industrial relations, environment, combatting bribery, consumer interests, science and technology, competition and taxation.
The first version of the OECD Guidelines dates from 1976 and the last update from 2011.
