European chemical manufacturers are covertly venting huge quantities of the powerful super greenhouse gas HFC-23, according to a study by the Swiss Federal Laboratories for Materials Science and Technology (EMPA). The report, published in the journal Geophysical Research Letters, says that Western Europe's emissions of HFC-23s – an 'F' or fluorinated gas mainly used as a refrigerant – are between 60-140% higher than officially reported. 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.
