ENGIE Named to Dow Jones Sustainability World Index and Dow Jones Sustainability Europe Index

PARIS – September 14, 2015 – ENGIE has been named to the two most prestigious Environmental, Social and Governance (ESG) indices: the
Dow Jones Sustainability World Index and the Dow Jones Sustainability Europe Index, established by the extrafinancial
rating agency, RobecoSAM.

The Group’s presence in these indices places it among the top 10% of sustainability-driven companies in the
“Multi- and Water Utilities” sector and recognizes its ongoing efforts in the environmental, corporate and societal
responsibility fields.

The designation cites in particular ENGIE’s customer relations, the adaptability of its business model, its
environmental performance management, water sector risk management, human resource development
measures and the quality of its stakeholder dialogue.

“We are very proud to be included in these prestigious indices. It is a crowning achievement after several years’
work at every level of the company to improve our extra-financial performance,” declared Valérie Bernis,
Executive Vice President in Charge of Communications, Marketing, and Corporate and Social Responsibility.
Introduced in 1999, the DJSI World is the first worldwide index to recognize the best-performing companies with
regard to sustainability. RobecoSAM recommends DJSI companies for sustainable investment. The
RobecoSAM rating is considered the most highly regarded by experts (including NGOs, public services,
academia, business and media) and, after the Carbon Disclosure Project, the most credible. (Rate the Raters Study – The 2013 Ratings Survey: Polling the Experts, produced jointly by GlobeScan and Sustainability.)

RobecoSAM analyzes a wide range of environmental, social and governance factors. The largest 3,400
companies worldwide are invited each year to participate in the assessment carried out by RobecoSAM. In
2015, of the 2500 companies evaluated across all sectors for inclusion in the DJSI World, 317 were selected. Of
the 600 companies assessed across all sectors for inclusion in the DJSI Europe, 162 were selected.

ENGIE develops its businesses (power, natural gas, energy services) around a model based on responsible growth to take on the major
challenges of energy’s transition to a low-carbon economy: access to sustainable energy, climate-change mitigation and adaptation, security
of supply and the rational use of resources. The Group provides individuals, cities and businesses with highly efficient and innovative
solutions largely based on its expertise in four key sectors: renewable energy, energy efficiency, liquefied natural gas and digital
technology. ENGIE employs 152,900 people worldwide and achieved revenues of €74.7 billion in 2014. The Group is listed on the Paris and
Brussels stock exchanges ( ENGI) and is represented in the main international indices: CAC 40, BEL 20, DJ Euro Stoxx 50, Euronext 100,
FTSE Eurotop 100, MSCI Europe and Euronext Vigeo (World 120, Eurozone 120, Europe 120 and France 20).
