The World Decides To Help The Climate By Helping The Ozone Layer

Posted by Jon Elliott on Tue, Oct 25, 2016

Pollution_1.jpgLast month I blogged about basic provisions of the Montreal Protocol on Substances that Deplete the Ozone Layer, and ongoing negotiations to expand it to require phaseout of chemicals that harm the stratospheric ozone layer and contribute to climate change (click here, and included links to early blogs on Montreal Protocol issues). At that time, proposals all focused on hydrofluorocarbons (HFCs). At that point, global HFC use was increasing by roughly 10% annually, driven primarily by expanding use for air conditioning as hot developing countries sought to catch up with comfort levels in their developed counterparts. Proposed timelines and end-targets for reversing that expansion varied considerably.

Earlier this month the parties to the Montreal Protocol met in Kigali, Rwanda and reached a deal. As should be expected from negotiations with nearly 200 parties, the result is a complicated compromise. However, implementation of the Kigali compromise would significantly reduce emissions of these greenhouse gases (GHGs) and perhaps mute climate change – the United Nations claims these changes would prevent up to 0.5 degrees Celsius of global warming by 2100.

Three Pathways For Three Sets Of Countries

The key to the international compromise was to divide countries into three groups, with different schedules and targets:

  • Developed nations including the United States - consumption will be cut to 90% of 2011-2013 baseline of most HFCs (plus 15% of those already covered by the Protocol) in 2019, declining to 15% by 2036.

  • Most developing nations, including China and over 100 others - consumption to peak in 2024 at 100% of 2020-2022 baseline of most HFCs (plus 25% of those already covered by the Protocol), declining to 20% by 2045.

  • 10 hot-climate developing countries, including India, Pakistan and some Gulf states - consumption to peak in 2028 at 100% of 2024-2026 baseline of most HFCs (plus 25% of those already covered by the Protocol), declining to 15% by 2047.

The delay allows developing countries more time to cap their emissions, and higher caps relative to baselines. Separate provisions address trade with non-parties, beginning in 2029.

Provisions For Financial Assistance

Countries also agreed to provide adequate financing for HFCs reduction. This will surely cost billions of dollars, but the actual amount of additional funding has been deferred for agreement at the next formal meeting of parties to the Protocol, in Montreal in 2017. Grants for research and development of affordable alternatives to hydrofluorocarbons will be the most immediate priority.

What Now?

This Amendment will enter into force on 1 January 2019, provided that at least twenty instruments of ratification have been filed by countries or regional groupings (such as the European Union). Observers have noted that this low hurdle would bind the United States even without approval by the U.S. Senate (since the U.S. long ago ratified the basic Montreal Protocol). Readers should also note that this hurdle is very low – compare it with the requirement for 55 countries with 55% of GHG emissions necessary for last year’s Paris Agreement on GHGs to enter force (I blogged about that Agreement here).

Because discussions about HFC phaseouts have been underway for years, efforts to develop alternatives have also been under way. For example, an international business group called the Consumer Goods Forum recently adopted a resolution encouraging its members (and other businesses) to incorporate HFC substitutes into their operations.

Implementation Checklist

Does the organization manufacture, import or use any ODS subject to the Montreal Protocol and/or CAA Title VI?

  • If the phase-out date for any ODS has passed, does the activity qualify with applicable exceptions or essential uses?

Does the organization manufacture, import or use any HFCs?

Has the organization reviewed any such activity to begin to identify alternatives for any ODS or HFC that is or may become subject to phaseout?
