Montreal Protocol and its Kigali Amendment: General information and current topics

Session Introduction

The session introduces the new knowledge sharing series of the Cooler Program funded by the International Climate Initiative of the German Ministry for the Environment. Barbara Akshai from IKIURA presents on the Montreal Protocol, its Kigali Amendment, and current international discussions.

Montreal Protocol Overview

• The Montreal Protocol, established in 1987 and ratified by all 197 UN parties, aims to protect the ozone layer by phasing out ozone-depleting substances (ODS).

• Achievements include a global reduction of ODS by 98% compared to 1990 levels, leading to a significant decrease in greenhouse gas emissions.

• The protocol's control measures are estimated to have reduced CO2 equivalents by 135 billion tons from 1990 to 2010.

Linkages with Environmental Agreements

• Halocarbons used in various products contribute to ozone depletion and climate change.

• The Montreal Protocol controls ODS production and consumption, while the Kigali Amendment focuses on hydrofluorocarbons (HFCs).

Technical Developments and Consequences

• Chlorofluorocarbons (CFCs) were replaced by hydrochlorofluorocarbons (HCFCs), which led to high global warming potential.

• Hydrofluorocarbons (HFCs), introduced as alternatives, have high GWP but no ozone-depleting potential.

Kigali Amendment Implementation

Discusses the implementation of the Kigali Amendment that targets HFC phase-down globally.

Kigali Amendment Details

• The amendment aims to reduce HFC consumption and production by over 80% by 2047.

• Different face-down schedules apply for Article 5 and non-Article 5 countries, allowing for a gradual reduction rather than a full phase-out.

Parallel Commitments

• Developing countries will simultaneously implement phase-out of HCFCs and face-down of HFCs between 2021 and 2030.

Detailed Overview of the Montreal Protocol

The discussion delves into the similarities between the phase-out plans for HCFCs and how an integrated compliance strategy could benefit Article Five countries in implementing these commitments efficiently.

HCFC Phase-Out Management Plans

• The HCFC phase-out management plans share similarities, suggesting that an integrated compliance strategy could aid Article Five countries in coordinated implementation.

Institutional Setup and Bodies

• The Ozone Secretariat, based in Kenya within UNIP, serves as the administrative office managing conference organization and decision implementation.

• The Meeting of the Parties (MOP) convenes all contracting parties to review protocol implementation, establish reporting guidelines, assess control measures, and address budgetary matters.

Assessment Panels and Committees

• Assessment panels like SAP, TEAP, and EEAP provide scientific, technological, and financial support to aid decision-making every four years through synthesis reports.

• The Implementation Committee reviews party submissions and information for report preparation while being elected by MOP.

Financial Mechanism and Executive Committee

• The Multilateral Fund (MLF), part of the financial mechanism under the London Amendment, offers financial assistance for technology transfer to aid parties in meeting control measures.

Current Topics: Energy Efficiency & CFC11 Emissions

This segment focuses on ongoing discussions regarding energy efficiency advancements and concerns related to CFC11 emissions post-global phase-out efforts.

Energy Efficiency Discussions

• Parties emphasize energy efficiency's importance with a 2019 decision prompting a report on best practices for energy-efficient technologies across sectors.

• Kigali Amendment highlights enhancing energy efficiency for climate benefits alongside refrigerant transition coordination.

CFC11 Emissions Concerns

• Recent discussions involve incomplete coverage in deep task force reports on applications like heat pumps. Funding mechanisms for energy efficiency remain unclear.

Detailed Analysis of Ozone Depletion Recovery

The speaker discusses the unexpected increase in emissions over a five-year period and its impact on the recovery of ozone depletion, focusing on CFC11 emissions and potential unreported production.

Anticipated Recovery of Ozone Depletion

• Estimated that the recovery of ozone depletion will not be significantly delayed due to the short duration of unexpected emissions.

• Unreported CFC11 emissions and production likely occurred from 2007 onwards, totaling between 320 and 700 kilotons.

• Cumulative unreported CFC11 production increased the bank by about 300 kilotons.

Opportunities for Recovery

• Limited opportunities exist to recover CFC11 quantities from active banks like insulation foams and centrifugal chillers.

• Challenges in waste recovery and destruction include high investment and operating costs compared to cheaper disposal methods like venting or landfill.
