The Rio+20 Secretariat is soliciting voluntary commitments to deliver concrete results for sustainable development. All commitments made ahead of Rio+20 and linked to its agenda will be displayed on the Rio+20 Voluntary Commitments website. Commitments are invited from all stakeholders, including: corporations, Major Group organizations, associations, academic institutions, philanthropic organizations, UN entities, partnerships involving more than one stakeholder, and Member States. In order to be recognized, commitments must be specific, measurable, funded, new (or an extension of an existing commitment), and must cover at least one of 23 sustainable development subject areas. The registry is easily searchable by these subject areas and by title keyword.
