Italy alone was found to be emitting 10-20 times more HFC-23s than it officially reports. The greenhouse gas has a global warming potential which is 14,800 times higher than CO2. The UK and the Netherlands also emitted around twice as much as they claimed, although the figures for France and Germany were “within the reported values”. There is no legal obligation on companies to reduce their HFC-23 waste gas emissions, but signatory states to the Kyoto Protocol must report their venting of the substance to the United Nations Framework Convention on Climate Change (UNFCCC).
