> Auditor's Report on the update of the reference document
>   As the statutory auditors of Veolia Environnement and in accordance with article 211-5-2 of the AMF regulation, we have verified, in accordance with professional standards applied in France, the information relating to the
>   financial position and historic financial statements contained in the reference document filed with AMF on April 5, 2005 under Registration number D.05-0351 and the update of this reference document here attached.
>   These documents are the responsibility of the President of the Board of Directors. It is our responsibility to report on the fairness of the information they contain with respect to the financial position and the financial
>   statements.
>   In our report on the reference document dated April 5, 2005, we concluded that, based on our procedures, we have nothing to report with respect to the fairness of the information on the financial position and the financial
>   statements presented in the reference document.
>   Our work, performed in accordance with professional standards applied in France, consisted in: 
>     - verifying that there was no event subsequent to the date of our report reminded above, that could affect the fairness of the
>   information on the financial position and the financial statements  presented in the reference document , and which was not the object of an update.
>   - assessing the fairness of the information with respect to the financial position and the financial statements and in verifying their consistency with the audited financial statements. We also read the other financial
>   information contained in the update of the reference document in order to identify any significant inconsistencies with the information related to the financial position and financial statements and to bring to your attention any manifest errors we
>   noted based on our general understanding of the company gained through our position as statutory auditors. This update does not present any isolated forecasted data resulting from a structured preparation process.
>   The annual statutory financial statements - prepared by the Management Board for the year ended December 31, 2002, and prepared by the Board of Directors for the year ended 2003 and 2004 - were audited by us in accordance
>   with professional standards applied in France, and were certified without qualification.
>   The consolidated financial statements for the years ended December 31, 2002, 2003 and 2004 were audited by us in accordance with professional standards applied in France, and certified without qualification. However, we
>     draw your attention to the change in accounting principles described in Note 2 "Summary of the significant accounting policies" to the consolidated financial statements, regarding the consolidation of certain entities as required by the provision of
>     CRC Regulation 04-03 of May 4, 2004.

| | - | ---------------------------------------------------------

---

> In the Specific Check section of our Report on the consolidated financial statements for the year ended December 31, 2004, we drew your attention to the paragraphs 5.1.3.9 and 5.1.3.10 of the management report regarding the
>     groups transition to International Financial Reporting Standards  IFRS.
>   Regarding pro forma information presented in the reference document, we remind you that this information is intended to show the effect of the achievement of any given operation or event - as if it occurred prior to its
>   real or reasonably forecast occurrence - on accounting and historical financial information. This information does not compulsory represent the financial situation or the performances that would have been noted if the operation or event had happened
>   prior to its real or reasonably forecast occurrence.
>   We audited the 2004 IFRS financial information - which is the responsibility of the Companys Board of Directors and which have been prepared as part of the conversion to the IFRS standards adopted in the European
>   Union - in accordance with French generally accepted auditing standards. We issued an unqualified opinion on the IFRS financial statements, in all material respects, in accordance with the basis set out in the notes to the 2004 IFRS financial
>   information. However, we drew your attention to the following matters:
>   - the paragraph 5.4.1.1 which explains why the 2004 IFRS financial information may be different from the 2004 IFRS financial information included in the IFRS financial statements
>     for the year ending 2005,
>   - the paragraph 5.4.2.1 which describes the accounting policies the Company expects to adopt regarding service concession arrangements, when the interpretation draft underway has been completed.
>   - the fact that the Company has prepared the 2004 IFRS financial information as part of its conversion to IFRS, as adopted in the European Union for the preparation of consolidated financial statements for the year ending
>   December 31, 2005. The 2004 IFRS financial information does not constitute a complete set of consolidated IFRS financial statements and therefore does not provide a fair presentation of the Companys financial position, results of operations
>   and cash flows in accordance with IFRS.
>   Based on our procedures, we have nothing to report with respect to the fairness of the information on the financial position and the financial statements presented in this reference document and its related update.

December 2004 and its results for the 2004 fiscal year.
