This year we took very concrete examples from sites, regions, product groups and central organizations to illustrate our performance in each section of the report and the growing company-wide awareness of corporate responsibility this reflects.

This report is in accordance with the 2006 Global Reporting Initiative (GRI) G3 Guidelines. Where relevant, we have used our own company indicators to give a complete and accurate picture of our performance. These are all prefixed 'ST'.

We explain methodologies used for measuring specific aspects of performance in the relevant sections. We also provide a glossary explaining acronyms and abbreviations on outside flap.

For feedback

We are committed to improving both our Corporate Responsibility Performance and the ways we communicate to our stakeholders. We encourage contributions and debate from all stakeholders and welcome feedback on the content and presentation of this report – as well as suggestions for next year. Before getting started on the preparation of this report, we organized around 30 phone interviews with our stakeholders in order to get feedback on last year's report and collect expectations for this new edition. We also launched an internal survey and around 50 managers gave us their feedback.

We paid attention to all the requests and tried to respond as well as possible.
