DNO strategies for greenhouse gas SF6 - a commentary by Sustainability First

The lack of any coherent long-run plan for addressing a highly intense and long-lived greenhouse gas, SF6, commonly used as an effective insulator in electricity substation equipment, is problematic. In this commentary, we argue that Distribution Network Operators, the firms that own and operate the lower-voltage networks, must establish a common reporting methodology proposed by Ofgem - both for SF6 leakage and for their SF6 inventories. This is too fundamental to ignore.
