Hydrofluorocarbons (HFCs), commonly used as refrigerants, can easily contribute to global warming and are being phased out in the European Union. However, as controls tighten, prices rise, and criminals sense business opportunities. The Environmental Investigation Agency (EIA), a British environmental organization, announced its investigation results in April. Criminals, desperate for high profits, smuggled large quantities of refrigerants from China and Turkey into Europe, exacerbating the climate crisis. HFCs are mainly used in refrigeration equipment, electronic cleaning and other fields. Although they will not destroy the ozone layer, they have high warming potential (GWP) and will accelerate global warming. Therefore, Europe and other industrial countries have promised to use 85% less in 2036 than in 2012. However, this product is still circulating in the market. “It is not difficult to find illegal HFCs on the European market,” Fin Walravens, senior climate specialist at the Environmental Investigation Agency, told Euractiv. “As long as you can successfully smuggle the most polluting and dirtiest gases, you can make money. The most money". He said that illegal HFCs trade not only exacerbates climate change, but also involves major tax evasion. The Environmental Investigation Agency published an investigation report three years ago, revealing that illegal HFCs were smuggled into the EU through Romania. The updated investigation "More Chilling Than Ever" in April this year further exposed the smuggling pipeline. Smugglers mainly purchase HFCs from Turkey and China, enter the EU through Bulgaria and other countries, and then sell them to Greece, Germany, France, Italy, Portugal and Spain.
