Excerpt from this story from Inside Climate News:
Just weeks after the Environmental Protection Agency began enforcing strict new limits on the production and use of hydrofluorocarbons, potent greenhouse gases commonly used in refrigeration and air conditioning equipment, the agency said it has blocked illegal imports of the harmful chemicals equal to the greenhouse gas emissions from burning 1.2 million barrels of oil.
Starting Jan. 1, U.S. chemical and equipment manufacturers were required to begin phasing down production and consumption of climate-damaging HFCs as mandated by the American Innovation and Manufacturing (AIM) Act, which was enacted in December 2020.
The rule will reduce domestic production and consumption of HFCs by 85 percent over the next 14 years and brings the U.S. into compliance with an international agreement known as the Kigali Amendment to the Montreal Protocol. The agreement is expected to prevent up to 0.5 Celsius of climate warming by 2100 through requiring manufacturers to use chemical refrigerants that are less damaging to the climate.
The HFC regulation places strict limits on the volume of HFCs that individual companies can produce or import. A key part of the rule is robust enforcement by an interagency task force that includes the EPA, Department of Homeland Security, U.S. Customs and Border Protection and other agencies to ensure that U.S. companies do not violate the rule by exceeding their limits with additional, illegal imports.
Over the past 10 weeks, the agencies have prevented illegal HFC shipments equivalent to approximately 530,000 metric tons of CO2 emissions, the EPA said in a press release on Tuesday.
