US, industry seek to cut HFC use

The White House today unveiled voluntary actions and other measures it said will reduce global use of hydroflourocarbons (HFCs) by 700mn metric tonnes of CO2 equivalent through 2025.

The steps include private-sector commitments across the HFC supply chain and Environmental Protection Agency actions to support a transition to more "climate friendly" alternatives.

Among the private sector steps, the Air Conditioning Heating & Refrigeration Institute said its members would commit to spending $5bn in new research and development and capital expenditures to develop low global-warming potential (GWP) technologies. The group is an industry association that represents 90pc of US air conditioning manufacturing and 70pc of the global industry.

The Alliance for Responsible Atmospheric Policy, an industry coalition the represents more than 95pc of US HFC production, said it would support a US-backed amendment to the Montreal Protocol to phase down the production and use of HFCs. The amendment, proposed by the US, Canada and Mexico in May, could cut global HFC use by more than 90bn CO2e through 2050, according to its supporters.

Several companies, including Coca Cola, DuPont and Honeywell, said they would slash the use of HFCs in their products, refrigeration equipment and production facilities.

EPA expanded its list of acceptable alternatives to HFCs and plans to engage with stakeholders to seek ways to transition away from high GWP HFCs.

HFCs are thousands of times more potent than CO2 at trapping heat in the atmosphere. They are commonly used in automobile air conditioning systems, vending machines and insulating foams. HFCs have been used to replace ozone-depleting substances that were phased out under the Montreal Protocol.

The announcements come a week before President Barack Obama is scheduled to attend the UN Climate Summit in New York City. Heads of state and other representatives from more than 160 countries are expected to attend. UN secretary-general Ban Ki-Moon hopes countries will use the summit to disclose new commitments to reduce GHGs and make contributions to the UN's Green Climate Fund.
