This document provides a summary of informal consultations on the draft outcome document for the 2012 UN Conference on Sustainable Development (Rio+20). It discusses the process of revising the draft document through negotiations between 23 April and 4 May 2012. While some progress was made and agreement reached on 21 paragraphs, over 400 paragraphs remained bracketed due to ongoing disagreements on issues like green economy, institutional framework for sustainable development, and sustainable development goals. An additional negotiation session was scheduled for late May to continue working on the document before Rio+20.
