Terna’s first and most immediate impact on the environment is the physical presence of pylons and power stations on the landscape.
Some of the solutions adopted by Terna include: reaching agreement with local communities on new projects before implementation; mitigating visual impact through "green masking" initiatives, using suitable vegetation or pylons designed to integrate more effectively into the surrounding landscape.
Regarding those issues of equal concern for the environment as a whole - such as waste CO2 emissions, electromagnetic fields and climate change - Terna carries out regular checks and monitoring programs, as well as developing processes aimed at minimizing their scope and effects.
Just think, for example, that 92% of the waste produced by Terna (81% in 2014: 4,489.9 tons) is recovered and recycled and only a small proportion is sent to landfill.
Because of its sensibility to the environment, Terna has over the years launched projects aimed at safeguarding biodiversity, including through alternative uses of its power lines: e.g. the "Nests on Pylons" project, which installs nest boxes to encourage reproduction by certain protected bird of prey species.

Terna provides the Country with the electricity transmission service through the high voltage electricity grid.

Environmentally, the most evident impact is the physical presence of the lines and power stations and their interaction with the surrounding environment, natural and man made. This is the premise of Terna’s environmental policy, whose commitment is to continually improve all significant environmental impacts, such as visual clutter, noise, electromagnetic fields and waste.

With a responsible approach towards the important theme of climate change, Terna also monitors its greenhouse gas emissions, that is however reduced due to the nature of its business that does not include the production of electricity.

Terna’s attention to the environment is reflected in the following features:

  • MANAGEMENT OF THE EXISTING LINES

    With regard to the existing lines and their management, Terna has developed a System of Environmental Management, obtaining, since 2007, the UNI EN ISO 14001 Certification. This certification, renewed in July 2013 for the period 2014-2016, regards all of Terna’s activities and covers the entire transmission grid (stations, lines) and offices.
  • PLANNING AND SUSTAINABLE DEVELOPMENT OF THE ELECTRICITY GRID

    Building new infrastructures is addressed by Terna with a precautionary approach that takes into consideration the environmental impact already from the stage of strategic planning. Attention to the environment and to the territory is implemented in cooperation with the local authorities (Regions, Provinces, Municipalities, Park authorities and others) aimed at identifying the best location of the new lines.

    The technical instrument used is the SEA - Strategic Environmental Assessment that Terna has been adopting - also for single projects - since 2001, way before the SEA became mandatory by law, for the ten year development plan of the electricity grid.
  • AGREEMENTS WITH ENVIRONMENTAL ASSOCIATIONS

    Attention to the environment and biodiversity is the subject of specific cooperation agreements in collaboration with the principal environmental organizations (WWF, LIPU) designed to emphasize nature conservation in the planning activities and maintenance of the electricity grid.
  • ENVIRONMENTAL COSTS

    Terna’s commitment to the environment is also reflected by the costs incurred for environmental reasons, both as operating expenses and investments. This separate presentation of environmental costs was drafted for the first time in 2009, following a project in which Terna’s general and industrial accounts were reinterpreted.
