- SF6 gas emission makes up of 3% of overall greenhouse gas, while the growth rate keeps at 14.7%.

Towards Green Environment – Reduce SF6 gas

Montreal Protocol - An international treaty designed to protect the ozone layer by phasing out the production of numerous substances that are responsible for the Ozone depletion.

- In terms of global warming potential, SF6 is 23,900 times stronger than CO2. (i.e. One ton of SF6 is equivalent to 23,900 tons of CO2.)

- SF6 is synthetic and it does not have a natural sink or any effective disposal methods.

- The atmospheric lifetime for SF6 is 3,200 years while CO2 is 100~200 years.

Most Powerful Greenhouse Gas – SF6

- In 2014, the European Commission tried to ban SF6 (in the framework of its F-Gas Regulation No. 517/2014), but it did not affect its use in the electrical industry. The reason for this was that, at the time, there were no commercially viable SF6-free alternatives to the existing switchgear.

- This regulation will be revised in 2020 where new technologies on the market will be assessed to see if they could possibly lead to a reduction in the usage of SF6.

- Bulox Power will reduce the carbon footprint by introducing BULOX ADVANCE SOLID INSULATED SWITCHGEAR - BASIS.
