Throughout the development of our reporting, we have sought continual improvement to data collection, collation and reporting, and have responded to recommendations and suggestions for improvement made by our independent third party assurors.

The Group’s Sustainable Development reporting covers all of the activities over which it exerts operating control. Every published indicator has been selected in relation to the Group’s key action areas and the indicator’s relevance to the Group’s activities. The indicators are defined after broad internal consultation, and are consistent with the GRI⁽¹⁾ guidelines and the Greenhouse Gas Protocol for reporting energy and CO₂ emissions.

The processes used to accumulate the data were verified by the Group’s Internal Control Department for 2008, 2009 and 2010 data. To prepare for the new regulatory obligations arising from the “Grenelle II” environmental law, we tasked Deloitte with checking our data collection processes and a selection of indicators for 2011.

Imerys also works to continuously improve the quality and accuracy of its reporting. A new reporting platform was rolled out in 2012. Under the new regulatory obligations stemming from the French environmental law “Grenelle II”, the Group assigned the firm Deloitte to verify its data collection processes and selected indicators for 2012. This assignment resulted in a report that is shown on pages 141-142 of chapter 5 of the 2012 Registration Document. The indicators verified by Deloitte are marked with an asterisk*.

The 2008, 2009 and 2010 data regarding the environment, health & safety presented in this section are different from those published in the 2010 Annual Report. The main sources of difference are allowance for some changes in Group structure, and the correction of some reporting errors.
