Résumé

The authors estimate that climate benefits resulting from the Montreal Protocol – which regulates ozone-depleting CFCs and HCFCs – will soon be counterbalanced by HFC emissions, which are currently increasing at 10 to 15% annually. At the moment, the HFC contribution to climate change is relatively small – about 0.012 W/m2 for all CFC substitutes combined – but could rise to 0.25 to 0.4 W/m2 by 2050. The scientists recommend modifying the Montreal Protocol so that it covers the use of long-lived HFCs.
