Since 2005, our Sustainable Development reporting has covered all activities over which we exert operating control. Every published indicator was selected in relation to its key action area and its relevance to the Group’s activities. The indicators are defined internally in consultation with the competent managers and are consisted with the GRI^(*) guidelines and the Greenhouse Gas Protocol for reporting energy and CO₂ emissions.

The methodology adopted for the definition of each indicator can be found in the Methodology section of our website.

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

Imerys also work to improve the quality and accuracy of our reporting. To build on the work done centrally by our Internal Control Department and our EHS audit teams, the Group tasked Deloitte with checking our data collection processes and a selection of indicators for 2011. A new data collection tool 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*.
