A basic requirement for persistent and long-term energy production is maintaining a safe, healthy and diverse environment. Pohjolan Voima's production companies have certified environmental management systems that comply with the ISO 14001 standard. In addition, Teollisuuden Voima is registered in the EMAS. All operations related to the construction phase of the Olkiluoto 3 project are covered by a certified environmental management system. Environmental programmes included in the systems ensure continuous improvement of operations.

All of Pohjolan Voima’s power plants have valid environmental and water permits. Renewal of the environmental permits of several thermal power plants, required by the Environmental Protection Act, is still underway due to the long permit process. The legislation in force and the currently valid permits are complied with at these plants. Similarly, TVO operates in accordance with environmental permits and the environmental management system. Pohjolan Voima is committed to good management and continuous improvement of environmental issues. Environmental protection not only means compliance with legal requirements but also efficient use of raw materials and safe handling, recycling and final disposal of by-products and waste. Pohjolan Voima aims to recycle as much of the by-products into raw materials as possible. Key environmental information is published by Pohjolan Voima in its annual report as well as on its website, which also contains the statutory information concerning electricity sources and emissions.
