The Eni share has once again been included in the Dow Jones Sustainability World index for 2011.

It was first included in 2007 and, in 2008, Eni was named best performer in the oil & gas sector.

The DJSI World 2011 includes 342 companies – selected on the basis of economic, social and environmental criteria – from among the top 2,500 companies by market capitalisation in the Dow Jones Global Large-Cap Total index. The companies in the oil & gas sector in the DJSI World 2011 number 12 out of an eligible 112.

Eni has also been confirmed on the Dow Jones Sustainability Europe 2011 for the third consecutive year. The DJSI Europe number 3 company in the oil & gas sector out of an eligible 17.

The selection is of the best-in-class type: only 10% of the best evaluated companies are admitted to the DJSI World index (20% for DJSI Europe). The evaluation is made by Sam, a specialised investment house focused exclusively in socially responsible investments, and subject to external verification.

 Total assets under management in DJSI-based investment vehicles now stand at close to $9 billion.

Eni has been confirmed in the FTSE4Good sustainability index in the half-yearly review in September 2011.

Evaluation for inclusion of the FTSE4Good index is not made on the basis of best in class. In fact the specialised index includes only companies from the FTSE Global index that comply with pre-determined economic, environmental and social requisites. Special significance is given to criteria concerning climate change, the protection of human rights and transparency in the procurement chain.

Eni is among the sector leaders of the 2010 Carbon Disclosure Project (CDP) and has been included in the Carbon Performance Leadership Index (CPLI) which, from this year, indicates companies that integrate the risks and opportunities of climate change in the business, establishing targets for the containment of greenhouse gas emissions and have already recorded significant reductions. The Eni share was the leader in its sector, also in 2007 and 2008, for the quality of the communication of the company's climate change strategy (Carbon Disclosure Leadership Index – CDLI).

Eni has been involved in the Carbon Disclosure Project since it began in 2003, and makes public its replies to the questionnaire. The initiative launched by Rockefeller Philanthropy Advisors of New York with the support of 300 institutional investors, aims to make public the strategies for greenhouse gas emissions management of the leading companies by market capitalisation on the FTSE Global Index. The Carbon Disclosure Project 2011 represents 551 international investors with assets under management of more than $71 trillion.

Eni, in 2011, has been included in seven of the ECPI Sustainability indices (www.ecpigroup.com), among others in the ECPI Ethical Euro Equity and the ECPI Global Carbon Equity. ECPI monitors more than 4,000 listed companies through a certified methodology with the goal to develop a synthetic measure of the ESG (Environmental, Social e Governance) risk-opportunity profile of a company.

The ECPI Ethical Index Euro is composed of 150 European companies with high levels of capitalization that pass ECPI's ESG and controversial sector screening. In the fourth quarter of 2011, the index included 6 companies in the "Oil integrated" sector.

The ECPI Global Carbon Equity is composed of the 40 companies from carbon-intensive sectors (Utilities, Basic Materials, Industrial and Energy) best equipped to deal with a world of rising carbon emissions and tougher climate legislation.
