Emissions of the powerful greenhouse gas Sulfr hexafluoride are rising

Energy consumption and production contribute to two-thirds of global emissions, and 81% of the global energy system is still based on fossil fuels, the same percentage as 30 years ago. Plus, improvements in the energy intensity of the global economy (the amount of energy used per unit of economic activity) are slowing.

Sulfur Hexafluoride (Sulfr hexafluoride) Recovery - Nitrogen Systems and Gas

Sulfur hexafluoride, gaz sf6, is used around the world as a dielectric medium for high-voltage circuit breakers, switchgear, and other electrical equipment. Additionally, it is used for the filling of insulated windows and for the casting of magnesium. gaz sf6 is expensive and is also a powerful green house gas (20,000 times more potent than CO2).
