Negotiators wrapped up a meeting in Bali on Friday without agreeing to rachet down the global use of ozone-depleting chemicals called hydrofluorocarbons (HFCs), which are a growing contributor to climate change.
Officials from the United States and the Federated States of Micronesia pushed for a phase-down in the use of HFCs, which are used as industrial refrigerants, as part of the 1987 Montreal Protocol agreement. HFC emissions are on the rise worldwide, in part because they serve as a substitute for ozone-depleting chemicals already eliminated under the pact.
Although 108 of the treaty’s 197 signatories backed the proposal, it failed to pass because China and India objected. The chemicals, which are used in refrigeration, air conditioning and insulating foams, are increasingly popular in developing countries such as India. The measure would have capped the total production of HFCs in 2014 and then lowered it by 15 percent every three years for the next 30 years.
