ABOUT THIS REPORT

For the third consecutive year, SUEZ is publishing an Integrated Report, presenting the company's strategic, forward-looking vision and the results it achieved in 2017 on behalf of all its stakeholders. From 2016, this report took the place of the Annual Report and the Sustainable Development Report.

In accordance with the International Integrated Reporting Council (IIRC) frame of reference, this reporting model is part of a movement that is gaining momentum in the business world. It meets the new needs of investors, customers, business partners, NGOs and employees to understand, analyse and measure the overall performance of a company and its interactions with society.

This report covers the 2017 fiscal year and is based on data from the 2017 Reference Document (a) and the reporting results for the 2017-2021 Roadmap (b). It highlights links between economic, financial and extra-financial (environmental, employment and governance) issues.

Defined by the Group s governing bodies and Business Units, the Integrated Report offers the keys to understanding and analysing SUEZ activities worldwide:

- the framework for value creation; - the socio-economic footprint of the Group s activity worldwide; - its carbon footprint; - its performance considered from the viewpoint of all the different stakeholders; - how it exercises its duty of vigilance and respect for human rights.

The company s internal and external stakeholders have contributed to the Integrated Report campaign since 2015, questioning and enriching it. SUEZ would like to thank them heartily.
