The purpose of these agencies is to asses the policies that have been implemented and the social and environmental performance of companies.

Thanks to its excellent performance, Veolia Environnement (Veolia Water is one of its divisions) has been listed in the following sustainable development indexes (as of October 1, 2006):

• - the Dow Jones Sustainability Indexes - DJSI World and DJSI EURO STOXX
  VE has been selected as the leading company in the water sector for the DJSI EURO STOXX
• - the FTSE4Good (Financial Times and London Stock Exchange)
• - the ASPI Eurozone Index (Advance Sustainable Performance Indexes)
• - the Ethibel Sustainability Index

In the same way that an index such as the CAC 40 mirrors what is happening on the stock exchange, sustainable development indexes provide a reference point for the social and environmental performance of companies. To have been listed by one of them means a company's work in these areas has been acknowledged.

Veolia Environnement has also been singled out for the quality of its communications with regard to social and environmental responsibilities. In 2006, it was ranked second among French companies for the quality of its reporting in a study by Global Reporters, sponsored by the United Nations Environment Programme (UNEP).

In 2005 the CFIE (French Centre for Business Information) ranked Veolia Environnement the second best CAC 40 company for the quality of its response to the new legal requirements in France brought about by the New Economic Regulations - Nouvelles Régulations Financial (Loi NRE).
