  • Main sources of fluorinated gas emissions | Whats Your Impact

    CF4 and C2F6 emissions are sometimes created as a byproduct of the aluminum smelting process. This is caused by disruptions like when alumina levels are too low. The aluminum industry produces 12000 tonnes of CF4 and 900 tonnes of C2F6 annually, making it the largest source of PFC emissions.7.

  • 152.2.1.1.4 Hydrofluorocarbons - IPCC Wiki

    The sum of emissions of CF4 reported by aluminium producers and for non-aluminium production in EDGAR (Emission Database for Global Atmospheric Research) v4.0 accounts for only about half of global emissions inferred from atmospheric observations (Muhle et al., 2010). For C2F6, emissions reported to the UNFCCC are also substantially lower than

  • Global warming potential - Wikipedia

    Global warming potential (GWP) is the heat absorbed by any greenhouse gas in the atmosphere, as a multiple of the heat that would be absorbed by the same mass of carbon dioxide (CO 2).GWP is 1 for CO 2.For other gases it depends on the gas and the time frame. Some gases, like methane, have large GWP, since a ton of methane absorbs much more heat than a ton of CO 2.

  • Greenhouse gas - Wikipedia

    A greenhouse gas (sometimes abbreviated GHG) is a gas that absorbs and emits radiant energy within the thermal infrared range, causing the greenhouse effect. The primary greenhouse gases in Earths atmosphere are water vapor (H 2 O), carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2 O), and ozone (O 3).Without greenhouse gases, the average temperature of Earths surface would be about
