The information regarding environmental performance is drawn from management data, some of which is estimated. The data shown below relate to energy use (heating, transport and electricity), eco-efficiency, atmospheric emissions, use of water, paper and waste production. The main indicators used to measure the Telecom Italia Group’s environmental performance in 2015 performed as follows:

Total electricity procured and produced Up
Total CO2 atmospheric emissions Up
Total water consumption Up (*)
Eco-efficiency Up

(*) As explained further on, the review of the reporting method has meant that the quantities consumed in 2015 in Italy were significantly higher than those published in the sustainability Report in previous years. Whereas application of the same criteria to the calculation of previous consumption would presumably result in a reduction as compared with last year.
