This data point records the total direct emissions of sulphur hexafluoride (SF₆) from industrial processes or equipment within your operational control during the reporting year. SF₆ is an extremely potent greenhouse gas used mainly as an electrical insulator in high-voltage equipment, and in certain magnesium casting and semiconductor manufacturing processes. The figure should be reported in metric tonnes (tSF₆).
What to include:
SF₆ emissions from high-voltage switchgear, circuit breakers, and gas-insulated transmission lines.
SF₆ emissions from magnesium casting processes.
SF₆ emissions from semiconductor manufacturing processes.
Accidental releases and leakage events during installation, maintenance, or disposal of equipment.
All SF₆ emissions from facilities and equipment you own or control.
What not to include:
SF₆ held in storage that was not released during the reporting period.
Emissions from equipment not under your operational control.
Other fluorinated gases such as HFCs or PFCs (reported separately).
Fugitive emissions from unrelated processes.
Estimation Methodology:
If direct measurement via leak detection systems or gas handling logs is unavailable:
Use gas inventory records at the start and end of the reporting year.
Adjust for purchases and returns of SF₆ cylinders.
Assume the difference (after accounting for gas still in equipment) represents emissions.
Convert to tSF₆ if recorded in kilograms.
For consolidated GHG totals in CO₂e: tCO₂e = tSF₆ × 25,200 (IPCC AR6, 100-year GWP).
