Rome, 9 February 2023 - Terna is once again confirmed at the top for global sustainability. The company led by Stefano Donnarumma is among the 'Top 1%', the highest tier in the Sustainability Yearbook 2023, the leading industry publication from S&P Global, an international ratings agency that evaluated the ESG performance of over 7,800 companies worldwide. The excellent score of 91 out of 100 awarded by S&P Global in its Corporate Sustainability Assessment 2022 makes Terna the highest scoring company out of the 250 electricity utility companies analysed around the world, which averaged a score of 50 points.

The company that operates the Italian National Transmission Grid received the highest recognition in the Sustainability Yearbook for the eighth time in fourteen years of being included in the Dow Jones Sustainability Index.

This international recognition solidifies Terna's role as director and enabler of the energy transition towards an increasingly sustainable, secure and resilient electricity grid. Sustainability is a strategic driver and one of the pillars of Terna's operations. Of the approximately € 10 billion in overall investments that the transmission grid operator has earmarked in the updated version of the 2021- 2025 "Driving Energy" Industrial Plan, 99% are considered sustainable based on the eligibility criterion introduced by the European Taxonomy.

S&P Global's evaluation is based on strict economic, environmental, and social criteria spanning all ESG areas: environmental impact, community relations, management of human resources, workplace safety, stakeholder engagement, corporate governance, risk management, respect for human rights, and supply chain controls.

Terna's leadership in sustainability, assessed as a top performer by the main ESG rating agencies, is also evidenced by the company's inclusion in several main ESG indices besides the Dow Jones Sustainability Index, namely the Bloomberg Gender Equality Index, ECPI, Euronext Vigeo-Eiris, FTSE4Good, the GLIO/GRESB ESG Index, the MIB 40 ESG, the MSCI, S&P Global 1200 ESG, and Stoxx Global ESG Leaders.
