Our overall business carbon footprint has fallen since the beginning of the RIIO-T1 period. This is mainly as a result of reducing emissions that result from energy losses from our transmission lines. The carbon intensity of our network has fallen due to increased renewable generation.

Sulphur hexafluoride (SF6) is an extremely effective electrical insulator and has significant advantages over alternative materials. It is non-flammable, a critical requirement in the high voltage applications for which we use it. And, because of its effectiveness, it takes up less volume than an equivalent insulating volume of an oil alternative.
However, SF6 is also a greenhouse gas. As a responsible business, we continue to investigate and develop new ways to manage and reduce the impact of our network, business activities and operations on the environment. We are exploring new initiatives and SF6 alternatives and capture techniques. These are part of our continued efforts to take care of the environment for current and future generations.
