Panel OKs Use of More Climate-Friendly Refrigerants in AC and Heat Pumps

"The new guidelines could save the equivalent of billions of metric tons of carbon dioxide emissions by 2050, but the U.S. could prove slow to adopt them."

"A secretive vote in the arcane and Byzantine world of international safety standards late last month may lead to a dramatic reduction in greenhouse gas emissions from home heating and cooling systems in the coming years.

In a closed-door process that concluded on April 29, two dozen technical experts from around the world voted unanimously to approve a proposed update to a household appliance safety standard set by the Geneva, Switzerland-based International Electrotechnical Commission (IEC).

The IEC sets safety standards for thousands of household appliances. The international standard serves as a guideline for country-specific safety standards such as UL, formerly Underwriters Laboratories, safety standard in the U.S. Details about the subcommittees that shape the safety standards are typically kept confidential. IEC declined to provide additional information about the vote, including the names of individual country representatives who approved the update.

The update, a draft copy of which IEC shared with Inside Climate News and which IEC plans to publish next month, could help solve a significant climate problem that has long bedeviled manufacturers of air conditioners and high efficiency electric heating systems known as heat pumps, which wanted to use more climate-friendly refrigerants but were prevented from doing so."
