To ensure environmental sustainability, all interventions are designed, implemented and monitored so as not to produce any impact, neither radiological nor conventional, on the environment.

Sogin has extended the existing environmental radiological monitoring and monitors, with continuous and programmed checks, the quality of the air, soil, surface and ground waters, sediments of the Dora Baltea river, as well as the main food products in the area: milk and corn. All the environmental radiological monitoring networks were established at the time of construction of the nuclear plants.

Every year, Sogin systematically carries out hundreds of measurements on the food and environmental matrices that constitute the environmental monitoring network. ARPA Piemonte carries out similar radiological monitoring and surveillance activities with its own network.

The results of the analyses and the values of the discharge formulas have always confirmed radiologically insignificant environmental impacts. The monitoring results are sent to ISPRA, Institute for Environmental Protection, and made public, also through the company's Sustaibility Report.​​​

​​Sogin’s Environmental Management System is ISO 14001 certified. After registration of the Caorso and Trino plants, in February 2017, Sogin also obtained the EMAS (Eco-Management and Audit Scheme) certificate for the activities at the Saluggia plant.

EMAS is a voluntary tool proposed by the European Community with which companies and government agencies can evaluate and improve their environmental performance and provide the public and all stakeholders with information concerning environmental management.
