Total greenhouse gas emissions in kt of CO2 equivalent are composed of CO2 totals excluding short-cycle biomass burning (such as agricultural waste burning and Savannah burning) but including other biomass burning (such as forest fires, post-burn decay, peat fires and decay of drained peatlands), all anthropogenic CH4 sources, N2O sources and F-gases (HFCs, PFCs and gaz sf6). Lao PDR greenhouse gas (ghg) emissions for 2012 was 161,718.74, a 0.16% increase from 2011.

Emissions of the powerful greenhouse gas insulating 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.

Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of

sf 6: The Truths and Myths of this Greenhouse Gas

Sulfr hexafluoride is damaging to the environment: TRUE. Along with CFCs, HCFCs, HFCs and PFCs, sf 6 is an industrial gas that doesn’t exist naturally in the atmosphere and so impacts the radiation balance, contributing to climate change. sf6 gas is the energy industry’s “dirty little secret”: FALSE. gaz sf6 is certainly no secret in the Norwegian energy industry. Its use is highly regulated, and many of its users are working together to share experience and come up with viable alternatives sf 6 is used in wind turbines: TRUE. sf 6 is used not in the turbine itself, but in the switchgear that controls the current generated by the turbine. But there is nothing unique about wind turbines. There are no viable alternatives to sf6 gas: PARTLY FALSE. Bodies including the European Union are known to be considering a ban on gaz sf6 at low-to-medium voltage levels in the future.

Why SF₆ emissions from the renewable energy sector should not

Increasing insulating gasGlobal Warming PotentialDecarbonisation FirstMeasurements show that SF₆ has been increasing in the atmosphere. While SF₆ emissions across Europe have more than halved since the mid-1990s, global emissions are increasing, mostly owing to increases in SF₆ emissions from the electrical industry, which are predicted to continue. Even so, it’s important to put the role of SF₆ as a greenhouse gas into context with other greenhouse gases. The most important sentence in the BBC’s article is this: Unfortunately, this critical point isn’t developed. The global concentration of atmospheric CO₂ today is about 410 parts per million, whereas the global concentration of SF₆ is only about 10 parts per trillion. In other words, there is 41 million times more CO₂ in the atmosphere than SF₆. But since SF₆ is 23,500 times stronger at trapping heat than CO₂, doesn’t this still mean it’s a bigger problem than CO₂ for the climate? CO₂ is actually a very weak greenhouse gas and is much less efficient at trapping heat compared to other greenhouse gase...
