...[In the "Zero Draft" Rio+20 Outcome Document, business] and industry are encouraged to show leadership in advancing a green economy founded on a sustainable path...geared towards inclusiveness and poverty eradication. The UN Working Group on the issue of human rights and transnational corporations and other business enterprises welcomes the Zero draft and supports the view set out in the draft on the role of the private sector. The business sector's contribution...is crucial. At the same time it has long since been acknowledged that business activities can have adverse impacts on people and environment...[It] is important to reiterate that all business enterprises also have a responsibility to respect human rights...We therefore recommend that the Governments negotiating at Rio+20 take into account the need to align outcome documents with established international standards for business and human rights, especially the UN Guiding Principles on Business and Human Rights.
