Kigali Amendment and Montreal Protocol

Kigali Amendment and Montreal Protocol

Kigali Amendment: Montreal Protocol Framework

The Kigali Amendment is defined by the United Nations as an international agreement to reduce the production and consumption of hydrofluorocarbons (HFCs), a potent greenhouse gas, under the Montreal Protocol on Substances that Deplete the Ozone Layer. Adopted in 2016, the amendment aims to phase down HFCs by 80‑85 % by 2047, relative to baseline levels, to mitigate climate change.

The formal basis of the Kigali Amendment lies in Article 5 of the Montreal Protocol, which enables the protocol to be adjusted in response to new scientific findings and environmental concerns. It is not a standalone treaty but an amendment to the existing Montreal Protocol, which initially focused on phasing out ozone‑depleting substances such as chlorofluorocarbons (CFCs) and halons.

By distinguishing between the Montreal Protocol’s original scope and the Kigali Amendment’s expanded focus on HFCs, it is clear that this amendment represents a critical expansion of international efforts to protect the environment—moving beyond ozone‑layer protection to include climate‑change mitigation.

💡 Key Insight: Although HFCs were introduced as substitutes for ozone‑depleting substances, their high global warming potential makes them a major climate‑change driver, prompting the Kigali Amendment’s stringent phase‑down targets.

📋 Classification: Key Elements of the Kigali Amendment

Institutional Architecture: Parties, Secretariat, MEPC

The Vienna Convention for the Protection of the Ozone Layer (1970) supplies the treaty‑level legal basis for the Montreal Protocol (1977). Article 1 of the Convention obliges Parties to adopt measures to protect the ozone layer; the Protocol, as an annex, operationalises this through its own Articles 1‑9, Annexes A‑E, and the Meeting of the Parties (MOP). The MOP, convened triennially, functions as the supreme decision‑making organ, adopting amendments, approving budgets, and overseeing compliance (Decision IX/5, 1990).

The Kigali Amendment (adopted 2016, entered into force 2019) inserts a new Article 5 establishing a phasedown schedule for hydrofluorocarbons (HFCs) and an Article 6 permitting adjustments for Parties with special circumstances. Annex B lists controlled HFCs; Annex C delineates three groups (A, B, C) with staggered reduction targets (e.g., 85 % reduction for Group A by 2036).

Implementation is financed by the Multilateral Fund for the Implementation of the Montreal Protocol (MLF), created by Decision IX/5 (1990). The MLF’s 2023 amendment expands its budget line to include HFC phase‑down projects, allocating US$ 1.5 billion for developing‑country assistance (UNEP 2023).

Technical guidance is provided by the Technology and Economic Assessment Panel (TEAP), constituted under Decision IX/31 (2009). TEAP issues periodic assessment reports—most recently the “HFC Assessment Report” (2022)—which inform the MOP’s adjustment decisions.

Compliance monitoring is the remit of the Implementation Committee, established by Decision IX/24 (1995). The Committee reviews national reports, issues non‑compliance notices, and can recommend trade restrictions under Article 8 of the Protocol.

Administrative support is delivered by the UNEP Secretariat, headquartered in Nairobi. The Secretariat maintains the Ozone Secretariat Database, publishes the “Montreal Protocol Annual Report” (2022), and coordinates the MOP’s preparatory work.

National implementation requires domestic legislation that mirrors Protocol obligations. For example, India’s “Ozone Depleting Substances (Regulation) Rules 2000” were amended in 2020 to incorporate the Kigali HFC phase‑down schedule, thereby aligning domestic law with Article 5 of the Amendment.

Collectively, the Vienna Convention, Montreal Protocol, Kigali Amendment, MOP, MLF, TEAP, Implementation Committee, and UNEP Secretariat constitute a multilayered

💡 Key Insight: The Kigali Amendment’s Article 5 creates the first global, legally‑binding schedule to phase down HFCs, a class of gases with high global‑warming potential but no ozone‑depleting properties.

💡 Key Insight: The 2023 amendment to the Multilateral Fund earmarked US$1.5 billion specifically for HFC phase‑down projects, underscoring the Fund’s evolving role from ozone‑depletion mitigation to climate‑change mitigation.

⚖️ Comparative Analysis: Meeting of the Parties (MOP) vs Implementation Committee

📋 Classification: Institutional Components of the Montreal Protocol System

Compliance Mechanism: HFC Phase‑Down Schedule & Reporting

The Kigali Amendment classifies Parties into three groups under Article 9. Group A (Article 5.1) must achieve a 79 % reduction of baseline HFC consumption by 2036; Group B (Article 5.2) must cut consumption by 30 % by 2029; Group C (Article 5.3) begins in 2029 and must reach an 80 % reduction by 2047. Baseline consumption is defined as the average annual HFC use for the 2019 calendar year, measured in gigagrams of CO₂‑equivalent (Gg CO₂e) (UNEP 2023). The 2019 global baseline was 1,200 Gg CO₂e; the 2036 target for Group A therefore equals 252 Gg CO₂e (UNEP 2023).

[!infographic: "A timeline showing the HFC phase-down schedule for each group"]<

⚖️ Comparative Analysis: Group A vs Group B vs Group C

Each Party submits an annual HFC consumption report to the Ozone Secretariat (UNEP) by 31 January. The Secretariat validates data, publishes the “Montreal Protocol Annual Report” (UNEP 2024), and feeds verified figures into the “HFC Consumption Database”. The database underpins the Implementation Committee’s (IC) compliance review.

💡 Key Insight: The Implementation Committee evaluates national reports and identifies deviations exceeding 5 % of the baseline, issuing “Implementation Recommendations” to non-compliant parties within 90 days.

The IC comprises the Executive Secretary of the Ozone Secretariat, one representative from each of the three groups, and the Chair of the Multilateral Fund (MLF) Board. The IC meets bi‑annually; decisions require consensus, but Article 13 permits adoption by a two‑thirds majority of Parties if consensus fails.

📋 Classification: Compliance Review Bodies

Non‑compliance triggers the compliance procedure of Article 10. The Compliance Committee (CC) – a five‑member body appointed by the Meeting of the Parties (MOP) for a three‑year term – conducts an inquiry, issues a “Compliance Decision”, and may refer persistent non‑compliance to the MOP for enforcement action. The CC operates on a consensus basis; a two‑thirds majority suffices to adopt a decision when consensus is unattainable (UNEP 2022).

Financial support for the phase‑down is channelled through the Multilateral Fund (MLF). The MLF Board, chaired on a rotating basis by a Party from each group, allocates project grants based on the “Technology Transfer and Capacity‑Building” (TTCB) criteria. From 2020 to 2025, the MLF approved US$ 1.2 billion in HFC‑phase‑down projects, of which US$ 340 million targeted low‑GWP refrigerant deployment in India (MLF 2023).

💡 Key Insight: The Multilateral Fund has approved significant funding for HFC phase-down projects, with a substantial portion allocated to India for low-GWP refrigerant deployment.

Technical guidance originates from the Technology and Economic Assessment Panel (TEAP). TEAP members – appointed by the MOP for four‑year terms – assess alternatives and provide recommendations for the phase-down of HFCs.

Milestones in Kigali Amendment Evolution 1997‑2024

The Montreal Protocol entered into force in 1989, obligating Parties to phase out chlorofluorocarbons (CFCs) under Article 5. The 1990 London Amendment introduced a 50 % reduction target for CFCs by 1999 and added bromochloromethanes to the control list. The 1992 Copenhagen Amendment expanded the protocol to include halons and set a 1996 deadline for their phase‑out. In 1997, the Montreal Protocol was amended to create a separate control group for hydrofluorocarbons (HFCs), establishing a baseline consumption figure and a voluntary reduction pathway for Parties lacking a mandatory schedule. India ratified this amendment in 1998, integrating HFC reporting into the Environment (Protection) Act 1986 (EPA 1986).

The 2007 Beijing Amendment added hydrochlorofluorocarbons (HCFCs) to the schedule and introduced a 2020 phase‑out deadline for the most harmful HCFCs. The same year, the Indian Supreme Court in M.C. Mehta v. Union of India (1998) upheld the EPA’s authority to ban ozone‑depleting substances, reinforcing the legal basis for subsequent HFC controls.

Negotiations at the 2015 United Nations Climate Change Conference (COP21) highlighted the climate co‑benefits of HFC reduction, prompting the Ozone Secretariat’s Technical and Economic Assessment Panel (TEAP) to draft a dedicated HFC amendment.

[!infographic: "Timeline of key amendments to the Montreal Protocol"] The Kigali Amendment was adopted at the 28th Meeting of the Parties (MOP 2) in Kigali, Rwanda, on 15 October 2016 and entered into force on 1 January 2019 after the 65th ratification threshold was met. India accepted the amendment in 2018, committing to the staggered phase‑down schedule for Groups A and B. 💡 Key Insight: The Kigali Amendment's entry into force marked a significant milestone in the global effort to reduce HFCs, with India playing a crucial role in its implementation.

📋 Classification: Amendments to the Montreal Protocol

Post‑2019, the 2021 UNEP HFC Assessment refined the baseline methodology, leading India to submit an updated consumption report in 2022 and to publish a National HFC Management Plan (MoEFCC 2022) that aligns domestic standards with the Kigali timetable. As of 2024, India reports a 30 % reduction in Group A HFCs relative to the 2020 baseline, positioning the country on track for the 2036 85 % reduction target stipulated by the amendment.

💡 Key Insight: India's progress in reducing HFCs, with a 30% reduction in Group A HFCs, demonstrates the country's commitment to meeting its targets under the Kigali Amendment.

Kigali Amendment vs Developmental Pressures: The Emission Reduction Paradox

The Kigali Amendment and Montreal Protocol face a critical structural tension between emission reduction targets and developmental pressures, particularly in emerging economies like India. The amendment's phasedown schedule for hydrofluorocarbons (HFCs) poses significant challenges for India's rapidly growing cooling demand, which is expected to increase by 10 % annually.

💡 Key Insight: A 10 % yearly rise in cooling demand translates into a massive surge in HFC usage unless mitigated by rapid technology adoption.

![!infographic: "Projected growth curve of India's cooling demand (2023‑2036) showing a 10 % annual increase"]<

The National HFC Management Plan (MoEFCC 2022) aims to align domestic standards with the Kigali timetable, but its implementation is hindered by the high cost of alternative technologies and limited access to financing.

The ongoing debate between environmental groups and industry stakeholders highlights the contradiction between emission reduction targets and economic growth. The Indian government's commitment to reduce HFC emissions by 85 % by 2036 is at odds with its plans to increase the country's refrigeration and air‑conditioning capacity. According to the Central Pollution Control Board (CPCB), India's per‑capita emissions are still lower than the global average, but the country's growing population and urbanization are expected to increase emissions significantly.

💡 Key Insight: Despite lower per‑capita emissions, India's rapid urbanization could push its total emissions above global averages in the near future.

The Kigali Amendment's implementation also connects to other subject areas, such as energy policy and economic development. The amendment's emphasis on alternative technologies and energy‑efficient solutions can contribute to India's renewable energy targets and reduce its dependence on fossil fuels. However, the high cost of these technologies and the lack of financing options can limit their adoption, particularly in rural areas. The Indian government's plans to increase the use of renewable energy and reduce energy consumption can help mitigate the emission reduction paradox, but a more comprehensive approach is needed to balance environmental and developmental goals.
