(a)

The indicator measures only energy purchased by Eni for its own consumption and does not include the quota bought and sold on the market, therefore the 2011-2012 data differ from the last year disclosure.

(b)

The figure is part of the environmental expenditures reported in the table “The environmental management system”.

Initiatives to improve energy efficiency include, in addition to traditional investments, interventions of a managerial nature such as the adoption and certification of Energy Management Systems (EMS). At the end of 2013, Eni’s energy management systems in the R&M Refineries of Livorno, Sannazzaro, Taranto and Venice were certified ISO 50001 as well as the chemical plants in Oberhausen and Szazhalombatta and the corporate headquarters of Eni SpA.

In the downstream sector, implementation of the measures in the energy saving plan continued, allowing excellent results to be achieved in terms of reducing consumption and containing emissions into the atmosphere. The measures undertaken between 2008 and 2013 enabled energy savings of over 300 thousand toe/year, the equivalent of a reduction in emissions of approximately 800 thousand tonnes of CO2. In the refining sector, the measures undertaken in 2013 were able to produce savings at a rate of about 34 ktoe/y; for the chemicals sector, the measures undertaken in 2013 will lead to savings at a rate of about 23 ktoe/y.

In the G&P sector initiatives continued to improve energy efficiency and achieve technical and economic optimization of electricity generation plant use, with repowering of the turbo-units of the power plants at Ferrera Erbognone, Mantua and Ferrara. In addition, EniPower continued to invest in renewable and alternative resources through the construction of photovoltaic plants and biomass power station at Porto Torres to produce electricity.
