SAM 2011 Silver Class
In virtue of the score obtained in the 2010 analysis, the rating agency SAM (Sustainable Asset Management) included Ternai – as the only transmission operator and the only Italian company – in the Silver Class of Electric Utilities (SAM, Sustainability Yearbook 2010).

Oekom Prime Status
In 2010 the German sustainability agency Oekom assessed Terna for the first time and included it immediately in the Prime Status class, which signals an excellent sustainability performance to socially responsible investors.

Carbon Disclosure Project
Even though it is not subject to obligations to reduce emissions nor to any kind of emissions trading scheme, Terna regularly publishes the data on its CO2 emissions and reports them every year to the Carbon Disclosure Project, an international initiative supported in 2010 by 534 investors who manage 64,000 billion dollars, whose purpose is to ensure transparency regarding the emissions generated by companies and the containment programs they implement.   
Among the 60 largest Italian companies, in 2010 Terna was first among the utilities and absolute second for its transparency in communication on its carbon footprint and was one of the 6 companies included in the Carbon Disclosure Leadership Index.

Global 1000 Sustainable Performance Leader 2010
Terna placed 44th in the Global 1000 Sustainable Performance Leader 2010, the special ranking based on the social, environmental, and governance results obtained by the 1,000 most highly capitalized companies in the world.
With this result Terna is in second place among both Italian companies and utilities worldwide. The indicators considered are those of the G3 version of the GRI - Global Reporting Initiative, the most widely used standard in the world in sustainability reporting.   

Fifth Enterprise Environment Award
With the electrification project carried out by several Terna employees in Kami (Bolivia) in March 2011, Terna won the fifth “Premio Impresa Ambiente” in the “best cooperation for sustainable development” category. The Award is an initiative of the Camera di Commercio Industria Artigianato e Agricoltura of Rome and is sponsored by the UNIDO - United Nations Industrial Developmenti Organization. It also represents the Italian selection for the European Business Awards for the Environment, which were instituted by the General Directorate for the Environment of the European Commission to promote the organizations that have contributed the sustainable development.
