In an important breakthrough, parties to the Montreal Protocol meeting in Dubai have agreed to a path forward aimed at phasing down hydrofluorocarbons (HFCs), a class of highly potent greenhouse gases. This progress adds to the momentum leading up to the UN climate talks starting later this month in Paris.
HFCs, chemicals widely used in refrigeration, air conditioning, and foam blowing, were developed in response to limits on ozone-depleting substances under the Montreal Protocol.
The United States and 40 other countries had put forth a range of proposals this year for phasing down HFCs. While these efforts fell short of producing a consensus amendment, extensive discussions throughout the week resulted in a path toward delivering an HFC phasedown amendment at a special, additional meeting of the parties to be held in 2016.
The fastest growing family of greenhouse gases – extremely potent hydrofluorocarbons (HFCs) -- aren’t going to be growing as fast in the future.
Today’s White House announcement of voluntary industry commitments to reduce hydrofluorocarbons (HFCs), along with new regulations put in place over the past year, have created game-changing shifts toward more environmentally friendly alternatives.
Developed as substitutes for ozone-depleting chlorofluorocarbons (CFCs) in the late 1980s, HFCs have become widely used worldwide in refrigerators, air conditioners, foam products, and aerosols. While they don’t contribute to ozone depletion, HFCs can trap 1,000 times or more heat in the atmosphere compared to carbon dioxide. This means they have a high global warming potential (GWP).
The amount of these compounds produced around the world has been growing at a rate of more than 10 percent per year. Unless controlled, emissions of HFCs could nearly triple in the U.S. by 2030. Strong international action to reduce HFCs could reduce temperature increases by 0.5 degrees Celsius by the end of the century, a critical contribution to global efforts to limit climate change.
The 16 voluntary industry commitments that make up today’s announcement highlight the innovation and leadership U.S. industry is showing in meeting the challenges of addressing climate change. These actions build on 22 commitments made by industry at a White House event just a year ago.
The latest working group meeting of the Montreal Protocol in Paris produced much useful discussion, but few concrete results due to limited but vocal opposition to an amendment to phase down hydrofluorcarbons (HFCs), a fast-growing, extremely potent family of global warming gases.
Efforts to achieve an amendment at the upcoming Meeting of the Parties in November had gained considerable momentum over the past year. Four proposals for an amendment had been submitted by India, the European Union, the Island States, and North America (Mexico, Canada and the U.S.). Beyond those proposals, the African States also have voiced their clear support for an amendment and recent meetings between President Obama and his counterparts from Brazil, India, and China had produced joint statements in support of action on HFCs under the Montreal Protocol.
Despite support for these proposals from nearly 100 countries, the week-long meeting in Paris this month failed to reach agreement on even starting the negotiating process through the creation of a contact group. After opposing these efforts over several meetings, Saudi Arabia and Kuwait (and other Gulf Cooperation Council countries) voiced their willingness to allow a two-stage process to move forward, but Pakistan stood firm in opposition, blocking any agreement.
In the absence of a mandate to begin negotiations, a number of sessions in Paris focused on a very useful exchange of views on issues raised by the four amendment proposals. India, China and others identified concerns about the costs and availability of alternatives to HFCs (including concerns about obstacles created by patents), the performance of these alternatives in high ambient temperatures, the time required to address flammability concerns of some key alternatives, the importance of energy efficiency, and the need for financing through the Protocol’s Multilateral Fund.
All agreed to hold another working group session prior to the November Meeting of the Parties. But time is fast running out on this year’s efforts to reach agreement on an HFC phasedown amendment.
What can be done to break this stalemate?
In the past, the executive director of the United Nations Environment Programme (UNEP) has sometimes played an active role convening senior representatives from key countries and driving needed compromise. During the early years of the Protocol, UNEP’s Mostafa Tolba was masterful in bringing key countries together to find a workable solution. Through informal, senior-level consultations, Tolba either forged a compromise text acceptable to all, or developed his own proposals that he would offer as a way forward.
While times have certainly changed, it may be that the moment has now arrived for Achim Steiner, UNEP’s current executive director, to actively engage with senior officials from key countries with the goal of advancing efforts at bringing HFCs into the Montreal Protocol.
As nations meet this week to work on an amendment to the Montreal Protocol to reduce hydrofluorocarbons (HFCs) -- one of the most potent greenhouse gases – a U.S. program is helping to reduce domestic emissions and demonstrate to other countries that there are practical, climate-friendly alternatives.
Hydrofluorocarbons, chemicals widely used in refrigeration, air conditioning, foam blowing, and other applications, were developed to replace ozone-depleting substances (primarily chlorofluorcarbons and hydrochlorofluorocarbons – CFCs and HCFCs) a few decades ago. But while HFCs don’t deplete the ozone layer, they do contribute to global warming, and, without policy intervention, their use is expected to grow dramatically over time.
Federal agencies trying to meet tougher sustainability mandates can make significant progress toward their goals by taking advantage of more efficient data storage and other information and communication technologies.
