Greenhouse gas mitigation strategies include reducing and avoiding emissions as well as enhancing the removal of GHGs from the atmosphere (Smith et al., 2008). Soil carbon (C) sequestration through biochar amendment has been proposed as an effective countermeasure for the rising concentration of atmospheric GHGs (Lal, 1999 ; Pan et al ., 2004

Sulfur hexafluoride circuit breakers protect electrical power stations and distribution systems by interrupting electric currents, when tripped by a protective relay.Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride (SF 6) gas to cool and quench the arc on opening a circuit.Advantages over other media include lower operating noise and no emission

SF6 is a strong greenhouse gas that could contribute to global warming. At an international treaty conference in Kyoto in 1997, SF6 was listed as one of the six greenhouse gases whose emissions should be reduced. SF6 is a very minor contributor to the total amount of greenhouse gases due to human activity, but it has a very long life in the

Due to its low gaseous viscosity, SF6 gas can efficiently transfer heat by convection. So due to high dielectric strength and high cooling effect, SF 6 gas is approximately 100 times more effective arc quenching media than air.. Due to these unique properties of this gas, SF6 circuit breaker is used in a complete range of medium voltage and high voltage electrical power system.

The airtightness of the chambers was tested using infrared gas analysis (WMA‐2 CO 2 analyser, PP Systems, UK) (Ly, Jensen, Bruun, de Neergaard, 2013) and CO 2 leakage was found to be minimal (<1%) over a deployment time of 2 hr. Gas samples were collected during the day between 9 a.m. and 11 a.m. to minimize the diurnal effect (Rahman et al

Gas samples were taken from all soil cores at seven time points, at day 4, 17, 31, 46, 67, 116 and 120. After the final gas sampling, the soil cores were stored at 4 °C and soil samples were collected within 4 days (10 cm depth).

UK greenhouse gas emissions were estimated to decrease by 38.0 per cent from 1990. Carbon dioxide (CO 2) is the most dominant greenhouse gas from the Kyoto basket of greenhouse gases, accounting for 81 per cent of total UK greenhouse gas emissions in 2015. UK net 2015 CO 2 emissions were estimated to be 403.8 million tonnes (Mt), which

For example, pure SF6 gas is used in gas insulated switchgears (GIS), gas insulated lines (GIL), and gas circuit breakers (GCB). One of practical solutions of controlling the emission rates of SF6 is to reuse by separation and recovery of SF6 of low concentration from the gases mixtures with nitrogen or air in the electric power industry.

Adopting CO2 as an alternative gas of SF6 in a gaseous type circuit breaker from the nature point of view, a 72kV-31.5kA group of CO2 gas circuit breaker model, which does not contain SF6 gas at all, was contrive and produced .In CO2 GCB model, some powerful technologies for current interruption by CO2 gas.
