“…The government can play a more significant role, such as offering incentives to electrical equipment utilities and manufacturers for reducing SF 6 . Critical reviews on Australia, the United States, and Japan show that these countries effectively address the same gaps that were identified for Malaysia, as indicated by the fact that SF 6 gas emissions are a key category in these countries' respective national GHG inventories [26][27][28].…”

Sulfur hexafluoride (SF6) gas is one of the high global warming potential (GWP) gases regulated under the Kyoto Protocol. In Malaysia’s Biennial Update Report 3, the Revised 1996 Intergovernmental Panel on Climate Change Guidelines were followed to estimate the SF6 emissions in the country, including the time series from 1990 to 2016. The majority of SF6 emissions originate from the use of this gas in electrical equipment, where it is predominantly used in transmission switch gears, which have increased rapidly because of increasing electricity demand. SF6 gas plays a significant role in greenhouse gas emissions in Malaysia because this gas has a higher GWP than carbon dioxide. Hence, this SF6 gas needs to be estimated using newer guidelines such as the 2006 IPCC Guidelines. Detailed activity data in the new methodology require stakeholders’ engagement with utility providers and government agencies. This paper describes the GHG inventory improvement plan, focusing on SF6 emissions for Industrial Processes and Product Use for Malaysia through this transition of methodology.

“…These synthetic FFGHGs are widely used in various industrial processes and are emitted as byproducts in certain industries. For example, SF 6 , NF 3 , and PFCs are emitted in the manufacture of semiconductors, − SF 6 in the insulation of electrical equipment, − and CF 4 and C 2 F 6 in the primary aluminum production. , Therefore, multiple industrial activities are the main sources of FFGHG emissions. Table S1 presents the emission sources of the six FFGHGs examined in this study.…”

Fully fluorinated greenhouse gases (FFGHGs), including sulfur hexafluoride (SF 6 ), nitrogen trifluoride (NF 3 ), and perfluorocarbons (PFCs), have drawn attention because they have long atmospheric lifetimes (up to thousands of years) and high global warming potential. Targeting SF 6 , NF 3 , and four PFCs (CF 4 , C 2 F 6 , C 3 F 8 , and c-C 4 F 8 ), this study projects future FFGHG emission patterns in China, explores their mitigation potential, and evaluates the effects of FFGHG emission reduction on the achievement of the country's carbon neutrality goal and climate change. FFGHG emissions are expected to increase consistently, ranging from 506 to 1356 Mt CO 2 -eq yr −1 in 2060 under the business-as-usual (BAU) scenario. If mitigation strategies are sufficiently employed, FFGHG emissions under three mitigation scenarios: Technologically Feasible 2030, Technologically Feasible 2050, and Technologically Feasible 2060, will eventually decrease to approximately 49−78, 70−110, and 98−164 Mt CO 2 -eq yr −1 in 2060, respectively, compared to the BAU scenario. Extensive implementation of FFGHG emission mitigation technologies will curb temperature rise by 0.008−0.013 °C under the slowest mitigation scenario, compared to 0.013−0.026 °C under the BAU scenario. Well-coordinated policies and reforms on FFGHG emission mitigation are recommended to prevent potential adverse effects on the climate to a certain extent.
