The World Summit on Sustainable Development (WSSD) in Johannesburg in 2002 brought together thousands of delegates who mapped out the future of the global sustainable development agenda. The resulting technical document, the Johannesburg Plan of Implementation (JPOI), identifies priorities in the implementation of Agenda 21 and other international agreements, and commitments that will take these priorities forward. This plain language version provides an invaluable reference to the outcomes of the WSSD by explaining the JPOI clearly for the lay person and expert alike.
