Ternai does not use raw materials, but electrical equipment, wires, and other elements, which are combined to be utilized in providing the transmission service. Produced for the first time in 2009, the following table shows the main non-renewable raw materials used by Terna. The weight is calculated on the basis of the quantity used, the average or typical weight of the single elements, and the share of raw materials contained. In some cases the elements consist of a single raw material (for example, insulators are 100% glass or ceramic, terminals 100% aluminum ), while in others an estimate was made of the main raw material (for example, copper accounts for 60% of the weight of an ATR transformer). Information is not currently available on the use of recycled materials by the supplier of the materials and equipment used.

The increase in the use of raw materials, in particular aluminum and steel, is due to the progress made on the construction of the new 380-kVi connecting lines included in the Developmenti Plan.

In office work, the main consumable is paper. Paper consumption regards the quantity purchased. The recording boundary has expanded since 2009 and now includes all offices, including the headquarters in Rome. The inclusion of the headquarters, where all the Company’s typical office work is concentrated, entailed a 57.6% increase in consumption. In 2010, paper consumption per person, net of blue-collar workers, amounted to about 34 kilograms.

All the paper purchased since the end of 2009 has been made with FSC pulp – that is, without any chlorine whatsoever – certified by the Forest Stewardship Council – www.fsc.org), which guarantees that the forests providing the cellulose are managed in accordance with sustainability criteria from the point of view of both the environment and human rights.

(1) The 2008 values were calculated only for offices in Italy.
(2) The coverage of the data regarding paper consumption is expressed as a percentage of the total number of executives and white-collar workers.

Water is not part of the production cycle of the transmission and dispatching of electricity. Normally the water used – for personal hygiene, cleaning offices, and air-conditioning systems – comes from aqueducts for civil uses. The increase in consumption in 2010 was due mainly to the leakage of two pipes in two local offices, which in one case was connected with the effect of freezing weather on the plumbing and in the other to work carried out in the vicinity of the pipe.
The data are recorded from the meters and bills of suppliers for the entire recording boundary.

(1) The 2008 number for water consumption in this document is different from the one reported in the preceding publications (105,851 m3 for the Group and 98,041 m3 for Italy). The values reported are the result of an estimate that adds the assumed consumption of the sites recorded from 2009 on to the consumption recorded in 2008. The year 2008 also includes the consumption of Ternai Partecipacoes. The consumption regarding the Italy boundary for 2008 was estimated to amount to 123,926 cubic meters.
