Following the Johannesburg summit, the United Nations Commission for Sustainable Development was granted responsibility for the management of Type II partnerships as its mandate and focus were considered most appropriate to the supervision of the partnerships. The UNCSD was created following the 1992 Rio summit with the sole mandate of overseeing the implementation of Agenda 21 and the Rio Declaration on Environment and Development, a focus which made the UNCSD highly amenable to the management of Type II agreements. The UNCSD supervises the 300+ Type II partnerships formed as a result of the summit, ensuring that the partnerships continue to implement the sustainable development goals agreed at Johannesburg.
