HFCs A Critical Link in Protecting Climate and the Ozone Layer 

This report, HFCs: A Critical Link in Protecting Climate and the Ozone Layer, says that the current contribution to climate forcing by HFCs is less than one per cent. However, it warns that HFCs are rapidly increasing in the atmosphere as they are adopted as ozone-friendly alternatives. Emissions of HFCs are growing at a rate of 8% per year, and by 2050, without action, they could rise so high that they almost cancel the tremendous climate benefits won earlier by the phase-out of CFCs and other ozone- depleting substances.
