Eco-efficiency

[G4-EN5] The Group measures its own energy efficiency by using an indicator that establishes a relationship between the service offered to the customer in terms of bits transmitted and the company’s impact on the environment represented by joules of energy consumed. The factors taken into consideration are the amounts of data and voice traffic of the fixed/ mobile networks and energy consumption for industrial purposes (transmission and climate control in exchanges), domestic purposes (electricity for office use, air conditioning and heating in the offices) and vehicles. The diagrams show the level of the eco-efficiency indicator over the past three years for the Domestic BU and Brazil.

Eco-efficiency Indicator - Domestic BU

In 2015 the value of the indicator calculated for the Domestic BU was 4,707 bit/joule, up by around 33% compared to 2014 and by over 66% compared to 2013. The commitment continues with the establishment for 2016 of an objective of 5,300 bit/joule, an increase of + 12% on the figure for 2015 (see 2016 Objectives in the Appendix).

           

Eco-efficiency Indicator - Brazil

The eco-efficiency indicator calculated for Brazil also showed continuous improvement over time: in 2015 it grew by 42% compared to 2014 and by 58% compared to 2013. This was due to a considerable increase in the data traffic over the last year which did not lead to a corresponding increase in the electricity consumption thanks to the efficiency of the network. The values of the indicators calculated respectively for Italy and Brazil are not directly comparable because the two organisations are very different in operational and environmental terms: e.g. in Brazil the traffic is primarily mobile and, as previously mentioned, no heating fuels are used in view of the particular climate conditions.
