Sustainability indexes

in

Terna's commitment to improving its ESG (Environmental, Social, Governance) performance is positively reflected in its sustainability ratings, inclusion in the main international stock exchange sustainability indexes and the appreciation seen from socially responsible investors.

During 2012 Terna presence was confirmed in all the main international stock exchange sustainability indexes and it was included in Vigeo's new range of ESG indexes.

In January 2013, Terna, the only Italian electricity company, was once again, for the second year running, included in the “RobecoSAM Sustainability Yearbook 2013” Gold Class, which this year numbers just 67 companies worldwide. To be included in the Gold Class requires a ratings score that must be within 1% of that of the leading company in the industry.
