India is the practical test of the Kigali Amendment’s promise. Cooling demand is rising for health, productive work, food, medicines and basic comfort, yet the country must sharply reduce high-global-warming-potential hydrofluorocarbons (HFCs). India ratified the amendment in 2021, freezes HFC production and consumption in 2028, and is scheduled to reach an 85% reduction from its baseline by 2047. That is a managed phase-down—not a sudden ban on existing air-conditioners—and it will succeed only if refrigerants, equipment efficiency, buildings, electricity systems and technician skills improve together.
What is the Kigali Amendment?
Adopted at the Montreal Protocol’s 28th Meeting of the Parties in Kigali, Rwanda, in October 2016, the amendment brings HFCs into the Montreal Protocol’s controlled-substance system. HFCs generally do not deplete the stratospheric ozone layer, unlike chlorofluorocarbons and hydrochlorofluorocarbons (HCFCs), but many HFCs have very high global-warming potential.
The UNEP Ozone Secretariat estimated in 2025 that HFCs represented about 2% of global greenhouse-gas emissions and were growing by more than 10% annually without controls. Full implementation of Kigali is projected to avoid up to 0.5°C of warming by 2100. Pairing the refrigerant transition with more efficient cooling equipment could nearly double the climate benefit.
The amendment does not prescribe one replacement gas or one type of appliance. It creates national schedules to control HFC production and consumption, leaving countries to choose technologies that meet safety, efficiency and local-use requirements.

What does Kigali mean for India?
India is in the amendment’s Article 5 Group 2 category. Its baseline is calculated from the average of HFC production and consumption in 2024, 2025 and 2026, plus 65% of the country’s HCFC baseline. Every percentage reduction below refers to that combined baseline.
| Milestone | India’s requirement | What it means |
|---|---|---|
| 2021 | Ratification on 27 September | India accepted the Kigali schedule under the Montreal Protocol. |
| 2024–2026 | Baseline years | The average HFC production and consumption over these years, plus 65% of the HCFC baseline, establishes the reference level. |
| 2028 | Freeze year | HFC production and consumption must stop growing above the agreed baseline. |
| 2032 | 10% reduction | Controlled HFC production and consumption must be 10% below the baseline. |
| 2037 | 20% reduction | The next scheduled step in the phase-down. |
| 2042 | 30% reduction | A further reduction from the baseline. |
| 2047 | 85% reduction | India’s scheduled long-term reduction target for controlled HFC production and consumption. |
An 85% phase-down is not an overnight prohibition on every HFC-based air-conditioner already installed. Existing equipment can remain in service subject to safety, maintenance, refrigerant availability and future rules. The schedule primarily changes what can be produced, imported and sold over time, while encouraging lower-GWP alternatives and better recovery of refrigerant.
Why India’s cooling choices matter
India’s cooling demand is tied to public health, worker productivity, food preservation, medicine, transport and household comfort. Benjamin Hickman, a UN Environment technical advisor in India, put the everyday stakes plainly: “Living in India you quickly understand the importance of keeping cool for your health and day-to-day functioning.”

The scale of future demand means switching refrigerants alone is insufficient. The India Cooling Action Plan sets a 20-year direction across buildings, appliances, transport, cold chains and industry. Its 2038 goals are up to 25% lower cooling demand, 25–30% lower refrigerant demand and up to 40% lower cooling-energy requirements. These are policy targets, not results already achieved.
UNEP also reported that if the average room-air-conditioner efficiency improves by 6% each year, India could save more than 64 TWh of electricity annually by 2030. The cited analysis estimated cumulative consumer benefits of up to US$25 billion. Both figures are scenario projections; they should not be read as measured nationwide savings.
The five decisions that determine whether cooling is sustainable
| Decision | Question to ask | Why it matters in India |
|---|---|---|
| Refrigerant | Does the refrigerant have substantially lower global-warming potential while meeting safety requirements? | A lower-GWP choice reduces the climate impact of leaks and end-of-life losses, but compatibility and handling rules still apply. |
| Equipment efficiency | How much electricity will the appliance use over its operating life? | Efficient equipment lowers running costs and eases pressure on a grid facing seasonal peaks. |
| Building and demand | Can shading, insulation, ventilation, fans or thermal storage reduce the cooling load? | Using less mechanical cooling reduces both electricity use and the amount of refrigerant equipment required. |
| Cost | What is the total cost of ownership rather than only the purchase price? | A higher upfront price can be offset by lower electricity and maintenance costs, but the payback depends on usage and tariffs. |
| Serviceability | Can trained technicians install, recover, leak-test and safely service the system? | Low-GWP refrigerants may have different pressure or flammability characteristics, making correct tools and training essential. |
Which refrigerant is climate-friendly?
There is no universal answer based only on a product label. A climate-friendlier refrigerant generally has lower global-warming potential, but the complete choice must also satisfy equipment compatibility, pressure limits, flammability classification, safety standards, warranty conditions and local rules.

Do not retrofit an existing system solely because a replacement refrigerant is advertised as “green.” A qualified technician must confirm that the compressor, oil, controls, heat exchangers and safety design are suitable. Refrigerant recovery and leak detection are especially important because releasing gas during servicing can erase much of the intended climate benefit.

Are energy-efficient air-conditioners worth it?
For a heavily used room AC, efficiency is often the most consequential household decision because electricity consumption continues throughout the equipment’s life. Compare the current Indian efficiency label and expected annual energy use, not just the purchase price. Also account for room size, outdoor temperature, set point, operating hours, installation quality and electricity tariff.
Efficiency works best alongside passive measures. External shading, reflective roofs, sealed gaps, insulation, ceiling fans and sensible thermostat settings can reduce the cooling load before the compressor starts. In larger buildings, thermal storage or district-cooling approaches may reduce peak demand, although suitability depends on the site.

The 6% annual efficiency-improvement pathway and the resulting 64 TWh projection come from a UNEP-cited analysis, not a guarantee for any individual appliance. A household should estimate savings from its own usage rather than assume the national scenario applies directly.

India’s Ozone Cell maintains the Montreal Protocol regulatory framework and issues quota-related orders. The Ozone Secretariat country profile records India’s Kigali ratification and HFC licensing-system reporting.
HCFC and HFC controls must not be confused. HCFCs damage the ozone layer as well as contributing to warming; HFCs generally do not deplete ozone but can have high global-warming potential. Under India’s Ozone-Depleting Substances Rules and amendments, HCFC use in manufacturing all new equipment has been prohibited from 1 January 2025. That HCFC manufacturing prohibition is separate from the staged HFC phase-down beginning with the 2028 freeze.

The government’s stated implementation approach includes a national HFC strategy, consultations with industry, amendments to the ODS Rules, licensing and reporting, low-GWP and energy-efficient technologies, domestic manufacturing and innovation, and upgraded servicing skills. These are implementation directions and infrastructure requirements; they do not establish that every product category, quota or downstream rule has already transitioned.
What households and businesses should do now
- Reduce the cooling load. Add shading, improve the building envelope, use fans and ventilation where appropriate, and avoid cooling unoccupied spaces.
- Compare lifetime efficiency. Check the current Indian energy label, annual consumption information and expected operating hours before buying an AC.
- Use qualified service. Require leak testing, correct charging and refrigerant recovery rather than venting during maintenance.
- Do not improvise a retrofit. Confirm refrigerant compatibility, pressure, flammability, safety standards and warranty terms with a trained technician.
- Plan for end of life. Arrange recovery and responsible disposal so refrigerant is not released when equipment is replaced.
What is still uncertain
The published policy documents and projections do not provide a 2026 audit of every Indian appliance model, a live national HFC quota, household-specific costs or measured nationwide emissions results. Product availability, star ratings, certification and service capability can differ by location and will change as the schedule advances. Those details should be checked against current Indian regulations and manufacturer documentation at the time of purchase or service.
