The Rio Tinto Alcan Prize is open to all not-for-profit, non-governmental, and civil society organizations based anywhere in the world that are working to advance the goals of economic, environmental, and social sustainability. The Prize was created to recognize the not-for-profit sector for its contributions to global sustainability both in the community and more widely by influencing policy.

In addition to the US$1 million Prize, nine grants worth US$15,000 each will be awarded to the shortlisted NGOs to invest in one of the following three approved courses: the postgraduate certificate in cross-sector partnership at Cambridge University, the LEAD Fellows training program or the postgraduate certificate in sustainable development from the University of London.

To ensure the objectivity of the Prize, Rio Tinto Alcan partners with the IBLF, which manages the entries and selection process. IBLF puts business at the heart of sustainable development and works with business, governments and civil society to enhance the contribution that companies can make to sustainable development. Rio Tinto Alcan does not have a voice on the Assessment or Adjudication Panels which are facilitated by IBLF, ensuring a rigorous and transparent approach.

The Rio Tinto Alcan Prize for Sustainability program is climate neutral and offsets CO2 emissions generated from management and travel activities relating to the Prize with contributions to Climate Care (www.climatecare.org).

* The Rio Tinto Alcan Prize for Sustainability was formerly known as the Alcan Prize for Sustainability.
