The following table includes the 100-year time horizon global warming potentials (GWP) relative to CO2. This table is adapted from the IPCC Fifth Assessment Report, 2014 (AR5)i. The AR5 values are the most recent, but the second assessment report (1995) and fourth assessment report (2007) values are also listed because they are sometimes used for

Global warming potential (GWP) is a measure of how much heat a greenhouse gas traps in the atmosphere over a specific time period, relative to carbon dioxide (CO 2). [1]: 2232 It is expressed as a multiple of warming caused by the same mass of carbon dioxide (CO 2). Therefore, by definition CO 2 has a GWP of 1.

These gases have 100-year global warming potentials (GWP), which are 140 to 11,700 times that of carbon dioxide, so their potential impact on climate change can be significant (Table 1).

2024年4月11日 · Get in-depth insights into Perfluorocarbon (PFC) emissions statistics. Access downloadable reports and interactive data visualizations to explore the impact and solutions. Perfluorocarbons (PFCs) can be produced in the primary aluminium reduction process, during events referred to as anode effects.

• Decline in European emissions of PFC-14, no trend for PFC -116 and PFC -218 • In general, estimates agree well with emissions data reported to the UNFCCC • Northwest European emissions of PFC -218 dominated by a single facility

当社では,PFCsガス用の処理装置として,各用途に応じて燃焼式,触媒式,F固定式(PFCsガス分解後のフッ素を処理剤に固定して処理する方法)を製品化し,PFCsガスの排出量削減に貢献している。 また,PFCsガスの削減量を正確に把握するために,処理装置の性能評価が重要となってきているが,当社では1987年に乾式排ガス処理装置(処理剤との吸着又は化学反応で排ガスを無害化する処理装置)を製品化して以来,性能評価のためのガス分析技術を長年培ってきた。 本報では, …
