摘要

Global-scale atmospheric measurements are used to investigate the effectiveness of recent adjustments to production and consumption controls on hydrochlorofluorocarbons (HCFCs) under the Montreal Protocol on Substances that Deplete the Ozone Layer (Montreal Protocol) and to assess recent projections of large increases in hydrofluorocarbon (HFC) production and emission. The results show that aggregate global HCFC emissions did not increase appreciably during 2007-2012 and suggest that the 2007 Adjustments to the Montreal Protocol played a role in limiting HCFC emissions well in advance of the 2013 cap on global production. HCFC emissions varied between 27 and 29 kt CFC-11-equivalent (eq)/y or 0.76 and 0.79 GtCO(2)-eq/y during this period. Despite slower than projected increases in aggregate HCFC emissions since 2007, total emissions of HFCs used as substitutes for HCFCs and chlorofluorocarbons (CFCs) have not increased more rapidly than rates projected [Velders, G. J. M.; Fahey, D. W.; Daniel, J. S.; McFarland, M.; Andersen, S. O. The Large Contribution of Projected HFC Emissions to Future Climate Forcing. Proc. Natl. Acad. Sci. U.S.A. 2009, 106, 10949-10954] for 2007-2012. HFC global emission magnitudes related to this substitution totaled 0.51 (-0.03, +0.04) GtCO(2)-eq/y in 2012, a magnitude about two times larger than emissions reported to the United Nations Framework Convention on Climate Change (UNFCCC) for these HFCs. Assuming accurate reporting to the UNFCCC, the results imply that developing countries (non-Annex I Parties) not reporting to the UNFCCC now account for nearly 50% of global HFC emissions used as substitutes for ozone-depleting substances (ODSs). Global HFC emissions (as CO2-eq) from ODS substitution can be attributed approximately equally to mobile air conditioning, commercial refrigeration, and the sum of all other applications.

J. M. Fahey，D. W .;丹尼尔，J。S .;麦克法兰（McFarland）; Andersen，S. O.预计的HFC排放量对未来气候强迫的巨大贡献。进程Natl。学院科学[美国，2009，106，10949-10954]为2007-2012。与该替代相关的HFC全球排放量在2012年总计为0.51（-0.03，+0.04）GtCO（2）-eq / y，该量级是《联合国气候变化框架公约》（UNFCCC）报告的排放量的两倍左右这些氢氟碳化合物。假设向UNFCCC进行了准确报告，结果表明未向UNFCCC报告的发展中国家（非附件一缔约方）目前占全球HFC排放量的近50％，这些HFC排放量是消耗臭氧层物质（ODS）的替代品。 ODS替代产生的全球HFC排放量（以CO2当量计）可以大致等同地归因于移动空调，商业制冷以及所有其他应用的总和。
