The rule aims to reduce the use of hydrofluorocarbons, called HFCs, by 85 percent over the next 15 years.
该规定的目标是在未来15年内将氢氟碳化物的使用量减少85%。
HFCs are industrial chemicals used in appliances like refrigerators and air conditioners.

Such gasses trap heat in the Earth's atmosphere.
这种气体将热量滞留在地球大气层中。
The EPA says HFCs are thousands of times more powerful than carbon dioxide in trapping heat.
美国国家环保局表示，氢氟碳化物的吸热能力是二氧化碳的数千倍。
The new rule is expected to take effect in late October.
新规定预计将于10月下旬生效。
The EPA said in a statement that limiting the use of HFCs worldwide is expected to avoid up to 0.5 degrees Celsius1 of global warming by 2100.

Along with other measures, the Biden administration said the rule can reduce 4.5 billion metric tons of carbon dioxide by 2050.
拜登政府表示，与其他措施一起，到2050年，这项规定可以减少45亿吨二氧化碳。
That is equal to almost three years' worth of gasses released by the U.S. power industry at 2019 levels.
这相当于美国电力行业按2019年排放量排放的将近三年的气体量。
Environmental and business groups supported the new HFC rules.

The Biden administration said it is also creating an interagency group to reduce HFCs, including preventing the illegal trade, production, sale or use of the climate-damaging gases.
拜登政府表示，它还将成立一个跨部门小组来减少氢氟碳化物，包括防止这种破坏气候的气体的非法贸易、生产、销售或使用。
The group led by the EPA and the Department of Homeland Security will punish violations4 of the law.
由美国国家环保局和国土安全部领导的这个小组将对违反法律的行为进行惩罚。
The EPA rule also creates a complex trading system that permits some use and trade of the chemicals.

The rule brings the U.S. in agreement with an amendment5 to the 1987 Montreal Protocol6.
这项规定使美国同意了1987年蒙特利尔议定书的修正案。
That is an international treaty aimed at reducing chemicals that damage the Earth's ozone7, a layer of oxygen that blocks harmful solar radiation.
这是一项旨在减少破坏地球臭氧层的化学物质的国际条约。臭氧层是一层氧气，可以阻挡有害的太阳辐射。
The United States has not yet approved the amendment.
