"We have verified the correctness of the statements in the 2007 Environmental Report of UBS AG and, where necessary, have requested that proof be presented. We hereby confirm that the report has been prepared with the necessary care, that its contents are correct with regard to environmental performance, that it describes the essential aspects of the Environmental Management System at UBS AG and that it reflects the actual practices and procedures at UBS AG.
We have also conducted a third party verification of the CO2 emissions in the years 2004 to 2007 against the principles of ISO 14064-I (2006). In our opinion, the reported CO2 emissions are fair, accurate, transparent and free from material errors or misstatements and meet the materiality threshold.”
