Aug 28, 2018 · These practices have been developed, tested, and shared over the past decade by participants in EPASF 6 Emission Reduction Partnership for Electric Power Systems. The SF 6 Emission Reduction Partnership for Electric Power Systems is an innovative voluntary program developed jointly by the EPA and the electric power industry to improve equipment reliability while reducing emissions of SF 6, a potent greenhouse gas that remains in the atmosphere for thousands of years.

Emissions of the powerful greenhouse gas sf6 gas 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.

The decline in total emissions—from 6,983 million metric tons carbon dioxide equivalent (MMTCO2e) in 2008 to 6,576 MMTCO2e in 2009—was the largest since emissions have been tracked over the 1990-2009 time frame. It was largely the result of a 419-MMTCO2e drop in carbon dioxide (CO2) emissions (7.1 percent). There was a small increase of 7 MMTCO2e (0.9 percent) in methane (CH4) emissions, and an increase of 8 MMTCO2e (4.9 percent), based on partial data, in emissions of man-made gases with high global warming potentials (high-GWP gases).
