ShareScientists recommend modifying the Montreal Protocol so that it covers the use of HFCs.
In a new paper published in Science, G. Velders et al. 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.
