Environmental ImpactCarbon FootprintSulphur HexafluorideOil LeakageBiodiversityOur main objective is to transport electricity in a safe, efficient, reliable and sustainable way. To power homes and businesses, energy has to travel long distances across many different landscapes. This inevitably has an effect on the environment. TenneT takes measures to limit and compensate the impact of its activities on nature - in terms of landscape or biodiversity. Beyond taking measures to limit and compensate for our own carbon emissions, we also contribute to reducing the overall carbon footprint of the Netherlands and Germany by facilitating the transition to renewable energy, in line with European Union targets. Our main environmental impact relates to carbon footprint, oil leakage and biodiversity. We do our utmost to reduce each of these impact areas.Get price

Sulfur hexafluoride - Wikipedia

The concentration of SF 6 in Earthtroposphere reached 10 parts per trillion (ppt) in year 2019, rising at 0.35 ppt/year. The increase over the prior 40 years was driven in large part by the expanding electric power sector, including fugitive emissions from banks of SF 6 gas contained in its medium- and high-voltage switchgear.
