Introduced in 1999, the Global Sullivan Principles expand upon the original Sullivan Principles, developed by The Reverend Leon H. Sullivan in 1977 as a voluntary code of conduct for companies doing business in apartheid South Africa. The principles cover areas of accountability, human rights, community engagement, environmental performance, marketplace practices, ethics and value chain responsibility. Endorsing companies and organizations are asked to take part in an annual reporting process to document and share their experiences in implementing the principles.
