Kigali Amendment: India’s Cooling Choices and Global Climate Goals

Context

1. The Kigali Amendment to the Montreal Protocol completed 10 years on 15 October 2026, highlighting global efforts to reduce hydrofluorocarbons (HFCs), which are potent greenhouse gases used in refrigeration and air-conditioning.
2. The amendment could prevent 0.3°C–0.5°C of global warming by 2100 if fully implemented.
3. Meanwhile, India’s cooling demand is projected to more than double by 2035, creating a challenge to balance affordable cooling, energy efficiency and climate commitments.

What is the Kigali Amendment?

1. It is a 2016 international agreement to progressively reduce the production and consumption of HFCs, which contribute significantly to global warming.
2. Adoption: On 15 October 2016 in Kigali, Rwanda, under the Montreal Protocol and entered into force on 1 January 2019.
3. Nature: It provides a legally binding, country-specific schedule for an HFC phase-down, rather than a complete ban.
4. Objective: It seeks to limit global warming by reducing emissions from refrigerants used in air-conditioners, refrigerators and other cooling equipment.

Why was the Kigali Amendment needed?

1. Montreal Protocol, 1987: The Montreal Protocol was adopted to protect the ozone layer by phasing out CFCs and other ozone-depleting substances. Since then, nearly 99% of controlled ozone-depleting substances have been eliminated, and the ozone layer is recovering.
2. Problem with HFCs: HFCs replaced CFCs because they do not damage the ozone layer. However, many HFCs have hundreds to thousands of times the global warming potential of CO₂ over 100 years.
3. Need for climate action: Controlling HFCs became necessary to address the climate impact of refrigeration and air-conditioning alongside the existing efforts to restore the ozone layer.

How does the Kigali Amendment work?

1. Progressive reduction: Countries follow agreed schedules to reduce HFC production and consumption over time, allowing industries to adopt alternative refrigerants and technologies.
2. Different timelines: Developed and developing countries follow differentiated schedules, giving developing economies additional time to manage the technological and financial transition.
3. International cooperation: The Montreal Protocol’s Multilateral Fund provides financial assistance to eligible developing countries to meet the additional costs of implementing the phase-down.
4. Climate benefit: Full implementation could avoid approximately 0.3°C–0.5°C of warming by 2100, supporting the Paris Agreement’s objective of limiting global temperature rise.

Why is cooling central to Climate Goals?

1. Direct emissions: HFCs escape into the atmosphere through refrigerant leakage during equipment use, servicing and disposal, contributing directly to global warming.
2. Indirect emissions: Air-conditioners and refrigerators consume electricity, which causes additional emissions when generated using fossil fuels.
3. Two-part solution: Replacing HFCs with lower-warming alternatives reduces direct emissions, while improving appliance efficiency reduces electricity consumption.
4. Global climate goals: The amendment supports the Paris Agreement’s objective of keeping global warming well below 2°C while pursuing efforts to limit it to 1.5°C.
5. Greater climate benefits: UNEP and the IEA estimate that combining the HFC transition with energy-efficiency improvements could roughly double the climate benefits.

Why Has the Montreal Protocol Succeeded?

1. Gradual tightening of targets: The protocol followed a start-and-strengthen approach, beginning with an initial target of 50% CFC reduction and progressively tightening controls as alternatives became available.
2. Clear timelines: Binding schedules gave industries certainty about future regulations and encouraged investment in alternative technologies.
3. Scientific guidance: Expert panels assessed available technologies and scientific evidence to guide decisions.
4. Support for developing countries: Longer compliance timelines and financial assistance through the Multilateral Fund helped developing countries manage the transition.
5. Adaptability: The protocol demonstrated that environmental agreements can become more ambitious as technology improves and alternatives become affordable.

What Are India’s Commitments Under the Kigali Amendment?

1. Ratification: India ratified the Kigali Amendment in 2021 and follows the phase-down schedule applicable to its country group.
2. India’s HFC reduction timeline:
   1. 2028 – Freeze HFC production and consumption at the agreed baseline.
   2. 2032 – Reduce HFC production and consumption by 10% below the baseline.
   3. 2047 – Achieve an 85% reduction from the baseline.

Challenges and Way Forward

Frequently Asked Questions (FAQs)

Q1. What is the Kigali Amendment, and when was it adopted?

The Kigali Amendment is a 2016 legally binding agreement under the Montreal Protocol to progressively reduce the production and consumption of hydrofluorocarbons (HFCs). It was adopted on 15 October 2016 in Kigali, Rwanda, and entered into force on 1 January 2019.

Q2. What are India’s key commitments under the Kigali Amendment?

India ratified the amendment in 2021 and follows a phased reduction schedule: freeze HFC production and consumption in 2028, reduce them by 10% below the baseline by 2032, and achieve an 85% reduction by 2047.

Q3. How does the Kigali Amendment support climate goals?

It reduces direct emissions from refrigerants, while energy-efficient cooling equipment reduces indirect emissions from electricity consumption. The amendment therefore supports the Paris Agreement’s climate objectives.

Q4. What are the major challenges in implementing the Kigali Amendment in India?

Key challenges include rapidly growing cooling demand, high transition costs, refrigerant leakage, inefficient appliances and limited global participation. Solutions include stronger efficiency standards, cleaner refrigerants, refrigerant recovery systems, technology transfer and financial assistance.
