# 731Appendix 8.A: Lifetimes, Radiative Efficiencies and Metric ValuesTable 8.A.1 |Radiative efficiencies (REs), lifetimes/adjustment times, AGWP and GWP values for 20 and 100 years, and AGTP and GTP values for 20, 50 and 100 years. Climate–carbon feedbacks are included for CO2while no climatefeedbacks are included for the other components (see discussion in Sections 8.7.1.4 and 8.7.2.1, Supplementary Material and notes below the table; Supplementary Material Table 8.SM.16 gives analogous values including climate–carbonfeedbacks for non-CO2emissions). For a complete list of chemical names and CAS numbers, and for accurate replications of metric values, see Supplementary Material Section 8.SM.13 and references therein.Acronym, CommonName or Chemical NameChemicalFormulaLifetime(Years)RadiativeEfficiency(W m–2ppb–1)AGWP20-year(W m–2yr kg–1)GWP20-yearAGWP100-year(W m–2yr kg–1)GWP100-yearAGTP20-year(K kg–1)GTP20-yearAGTP50-year(K kg–1)GTP50-yearAGTP100-year(K kg–1)GTP100-yearCarbon dioxideCO2see*1.37e-52.49e-1419.17e-1416.84e-1616.17e-1615.47e-161MethaneCH412.4†3.63e-42.09e-12842.61e-12284.62e-14678.69e-15142.34e-154Fossil methane‡CH412.4†3.63e-42.11e-12852.73e-12304.68e-14689.55e-15153.11e-156Nitrous OxideN2O121†3.00e-36.58e-122642.43e-112651.89e-132771.74e-132821.28e-13234ChlorofluorocarbonsCFC-11CCl3F45.00.261.72e-1069004.28e-1046604.71e-1268903.01e-1248901.28e-122340CFC-12CCl2F2100.00.322.69e-1010,8009.39e-1010,2007.71e-1211,3006.75e-1211,0004.62e-128450CFC-13CClF3640.00.252.71e-1010,9001.27e-0913,9007.99e-1211,7008.77e-1214,2008.71e-1215,900CFC-113CCl2FCClF285.00.301.62e-1064905.34e-1058204.60e-1267303.85e-1262502.45e-124470CFC-114CClF2CClF2190.00.311.92e-1077107.88e-1085905.60e-1281905.56e-1290204.68e-128550CFC-115CClF2CF31,020.00.201.46e-1058607.03e-1076704.32e-1263104.81e-1278104.91e-128980HydrochlorofluorocarbonsHCFC-21CHCl2F1.70.151.35e-115431.35e-111481.31e-131921.59e-14261.12e-1420HCFC-22CHClF211.90.211.32e-1052801.62e-1017602.87e-1242005.13e-138321.43e-13262HCFC-122CHCl2CF2Cl1.00.175.43e-122185.43e-12594.81e-14706.25e-15104.47e-158HCFC-122aCHFClCFCl23.40.212.36e-119452.37e-112582.91e-134262.99e-14481.96e-1436HCFC-123CHCl2CF31.30.157.28e-122927.28e-12796.71e-14988.45e-15146.00e-1511HCFC-123aCHClFCF2Cl4.00.233.37e-1113503.39e-113704.51e-136594.44e-14722.81e-1451HCFC-124CHClFCF35.90.204.67e-1118704.83e-115277.63e-1311207.46e-141214.03e-1474HCFC-132cCH2FCFCl24.30.173.07e-1112303.10e-113384.27e-136244.14e-14672.58e-1447HCFC-141bCH3CCl2F9.20.166.36e-1125507.17e-117821.27e-1218501.67e-132716.09e-14111HCFC-142bCH3CClF217.20.191.25e-1050201.82e-1019803.01e-1243908.46e-1313701.95e-13356HCFC-225caCHCl2CF2CF31.90.221.17e-114691.17e-111271.17e-131701.38e-14229.65e-1518HCFC-225cbCHClFCF2CClF25.90.294.65e-1118604.81e-115257.61e-1311107.43e-141204.01e-1473(E)-1-Chloro-3,3,3-trifluoroprop-1-enetrans-CF3CH=CHCl26.0 days0.041.37e-1351.37e-1311.09e-1521.54e-16<11.12e-16<1(continued on next page)

The uncertainty is dominated by AGWP for CO2and indirect effects. The uncertainty in GWP for N2O is estimated to ±20% and±30% for 20- and 100-year time horizon, with the largest contributions from CO2. The uncertainty in GWP for HFC-134a is estimated to ±25% and ±35% for 20- and 100-year time horizons while for CFC-11 the GWP the corresponding numbers are approximately±20% and ±35% (not accounting for the indirect effects). For CFC-12 the corresponding numbers are ±20 and ±30. The uncertainties estimated for HFC-134a and CFC-11 are assessed as representative for most other gases with similar or longer lifetimes. Forshorter-lived gases, the uncertainties will be larger. For GTP, few estimates are available in the literature. The uncertainty is assessed to be of the order of ±75% for the methane GTP100.*No single lifetime can be given. The impulse response function for CO2from Joos et al. (2013) has been used. See also Supplementary Material Section 8.SM.11.†Perturbation lifetime is used in calculation of metrics, not the lifetime of the atmospheric burden.(continued on next page)

# 738Table 8.A.1 Notes (continued)‡Metric values for CH4of fossil origin include the oxidation to CO2(based on Boucher et al., 2009). In applications of these values, inclusion of the CO2effect of fossil methane must be done with caution to avoid any double-counting because CO2emissionsnumbers are often based on total carbon content. Methane values without the CO2effect from fossil methane are thus appropriate for fossil methane sources for which the carbon has been accounted for elsewhere, or for biospheric methane sources for whichthere is abalance between CO2taken up by the biosphere and CO2produced from CH4oxidization. The addition effect on GWP and GTP represents lower limits from Boucher et al. (2009) and assume 50% of the carbon is deposited as formaldehyde to thesurface and is then lost. The upper limit in Boucher et al. (2009) made the assumption that this deposited formaldehyde was subsequently further oxidized to CO2.aRE is unchanged since AR4.bRE is unchanged since AR4 except the absolute forcing is increased by a factor of 1.04 to account for the change in the recommended RE of CFC-11.cBased on Rajakumar et al. (2006) (lifetime correction factor has been applied to account for non-homogeneous horizontal and vertical mixing).dBased on instantaneous RE from Baasandorj et al. (2010); Baasandorj et al. (2011) (correction factors have been applied to account for stratospheric temperature adjustment and non-homogeneous horizontal and vertical mixing).eBased on instantaneous RE fromab initiostudy of Bravo et al. (2010) (a factor 1.10 has been applied to account for stratospheric temperature adjustment).fBased on average instantaneous RE reported in literature (Vasekova et al., 2006; Bravo et al., 2010) (correction factors have been applied to account for stratospheric temperature adjustment and non-homogeneous horizontal and vertical mixing).gBased on instantaneous RE fromab initiostudies of Blowers et al. (2007, 2008)(correction factors have been applied to account for stratospheric temperature adjustment and non-homogeneous horizontal and vertical mixing).hBased on instantaneous RE from Heathfield et al. (1998) (correction factors have been applied to account for stratospheric temperature adjustment and non-homogeneous horizontal and vertical mixing).iNote that calculation of RE is based on calculated (ab initio) absorption cross-section and uncertainties are therefore larger than for calculations using experimental absorption cross section.jBased on instantaneous RE from Javadi et al. (2007) (correction factors have been applied to account for stratospheric temperature adjustment and non-homogeneous horizontal and vertical mixing).kBased on instantaneous RE from Andersen et al. (2010) (correction factors have been applied to account for stratospheric temperature adjustment and non-homogeneous horizontal and vertical mixing).The GTP values are calculated with a temperature impulse response function taken from Boucher and Reddy (2008).
