HFCs

Advancing toward phasing down HFCs

International negotiators made significant progress last week in Geneva at the first of several meetings this year aimed at phasing down hydrofluorocarbons (HFCs) through an amendment to the Montreal Protocol.

HFCs are fast growing, powerful greenhouse gases used as substitutes for ozone-depleting substances in refrigeration and air conditioning, as blowing agents, and as aerosol propellants.

In a stark departure from meetings in previous years, a number of key issues essential to reaching agreement on an HFC amendment were tentatively resolved and substantial progress was achieved on others.

For example, Saudi Arabia, Kuwait and other Gulf states had raised concerns about the lack of proven substitutes for air conditioning that are suitable for the extreme heat experienced in their countries. A proposal to allow a time-limited and geographically targeted exemption until substitutes have been demonstrated was proposed and tentatively agreed to at the meeting. (See our brief on how to structure an exemption.)

Another issue raised in the past by a number of parties concerns the potential conflict between actions on HFCs taken under the United Nations Framework Convention on Climate Change (UNFCCC) and any HFC amendment under the Montreal Protocol. In Geneva, there was broad agreement that the treaties were independent of each other, that they could be implemented in a way that would be complementary, and that an HFC amendment would not in any way require a prior authorizing act by the climate treaty.

A good deal of time was spent discussing issues related to funding associated with HFC controls in developing countries. While agreement exists that the Protocol’s Multilateral Fund would continue to be the primary vehicle for providing financial support for emission reduction projects, issues concerning guidelines detailing what projects would be funded were left unresolved. Among these issues is payment for licensing of intellectual property rights for patent-protected technologies to produce and use some of the substitute chemicals.

Action on HFCs heats up

We’re seeing new movement toward phasing down the fastest-growing group of greenhouse gases – hydrofluorocarbons, or HFCs. These chemicals are widely used in refrigerators, air conditioners, foam products, and aerosols. And while they don’t stay in the atmosphere long, they can trap 1,000 times or more heat compared to carbon dioxide.

This week, the U.S. Environmental Protection Agency (EPA) proposed new regulations demonstrating its commitment to limiting the use of HFCs domestically. It proposed changes to its significant new alternatives program (SNAP) aimed at expanding the list of acceptable alternatives that minimize impacts on global warming while also restricting the use of HFCs in sectors where alternatives are now available. EPA estimates the proposed rule could avoid up to 11 million metric tons of carbon dioxide equivalent in 2030, which is equal to the energy-related emissions from about one million homes for one year.

Internationally, one sign of growing support for acting on HFCs came this month during the first visit by a U.S. president to Argentina in almost two decades. President Obama and newly elected Argentinian President Mauricio Macri explored opportunities to partner to address global challenges like climate change.

They affirmed their commitment to take action this year to amend the Montreal Protocol to phase down HFCs, which are substitutes for ozone-depleting chlorofluorocarbons (CFCs) that were successfully phased out under the 1989 Montreal Protocol. The two leaders also endorsed the understandings reached at the Dubai Montreal Protocol meeting in November 2015 on financial support for developing countries to implement an HFC phasedown.

A key opportunity will come next week when Montreal Protocol negotiators meet in Geneva to build on the progress made toward reaching agreement this year on an HFC phasedown amendment.

Approaches to Structuring a High Ambient Temperature Exemption

Approaches to Structuring a High Ambient Temperature Exemption

As parties to the Montreal Protocol consider an amendment to phase down hydrofluorocarbons (HFCs), one critical concern is whether suitable alternatives for air-conditioning applications are available and adequately demonstrated for cooling capacity and energy efficiency under conditions of high ambient temperatures. Given the critical importance of these applications, one option being considered by parties is to provide a time-limited exemption for those uses in countries that could be adversely impacted by high ambient temperatures. This paper looks at a number of options for how such an exemption might be structured.

Breaking through the Montreal Protocol stalemate

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.

U.S. should act now to reduce short-lived pollutants damaging the climate

Last year’s extreme drought, wildfires and the devastation of Hurricane Sandy have driven home the high economic costs associated with extreme weather. The increasing frequency and intensity of such events make it clear that climate change presents a real and present danger. It no longer can be dismissed as a problem only of concern to our children or grandchildren.  

This increased urgency has also caused an important shift in our understanding of what actions are required to slow the rate of climate change. Recent studies have focused on the need for a two-pronged approach. Reducing emissions of carbon dioxide, some portion of which stays in the atmosphere for centuries, is critical to long-term efforts. But curbing greenhouse gases with shorter atmospheric lifetimes will have significant near-term climate and public health benefits.
