The Sullivan principles are a set of corporate codes of conduct developed by African-American preacher Reverend Leon Sullivan during his time on the board of General Motors in the 1970s. Focused on promoting corporate social responsibility and an end to racial segregation in the workplace, the principles were originally introduced in 1977 to pressure multinational corporations operating in apartheid South Africa. A new, ‘global’ set of Sullivan principles were introduced in 1999 in cooperation with the United Nations.
