The amendment does not ban existing air-conditioners. It phases down controlled HFC production and consumption while requiring changes in equipment design, buildings, servicing and electricity use.
What is the Kigali Amendment?
Parties to the Montreal Protocol adopted the Kigali Amendment in October 2016. It added hydrofluorocarbons (HFCs) to the treaty’s controlled-substance regime. HFCs generally do not deplete the stratospheric ozone layer, unlike older ozone-depleting substances, but many have very high global-warming potential.

The UNEP Ozone Secretariat said in 2025 that HFC emissions represented about 2% of global greenhouse-gas emissions and were growing by more than 10% a year without controls. Full implementation of Kigali is projected to avoid up to 0.5°C of warming by 2100. Combining the refrigerant transition with improvements in equipment efficiency could nearly double the climate benefit.
The amendment is therefore more than a refrigerant-substitution timetable. It is a test of whether countries can provide more cooling with less electricity, fewer refrigerant emissions and safer, better-maintained equipment.

What does Kigali mean for India?
India ratified the amendment on 27 September 2021. It is classified as an Article 5 Group 2 country and has a later schedule than countries that freeze HFC use earlier.
India’s baseline and freeze year
India’s baseline is calculated from the average of HFC production and consumption in 2024, 2025 and 2026, with 65% of the country’s HCFC baseline added to that calculation. The HFC freeze year is 2028. The baseline matters because every later reduction is measured against it; it is not a count of individual air-conditioners or a limit on one household’s use.
India’s negotiated phase-down steps
| Milestone | Reduction from India’s baseline | What it means |
|---|---|---|
| 2028 | Freeze year | Controlled HFC production and consumption must remain at the agreed baseline level. |
| 2032 | 10% | First scheduled reduction from the baseline. |
| 2037 | 20% | Further reduction in controlled HFC production and consumption. |
| 2042 | 30% | Progressive phase-down continues. |
| 2047 | 85% | Long-term reduction target under India’s schedule. |
The figures describe national control of production and consumption. An 85% phase-down in 2047 is not an overnight prohibition on every HFC-containing appliance already installed in India.
Will my air-conditioner be banned?
No blanket ban on existing household air-conditioners follows from the Kigali schedule. The amendment governs controlled HFC production and consumption, while India’s policies steer manufacturers toward alternatives and more efficient equipment over time.

Existing systems still need responsible servicing. A leak can release refrigerant directly, and an improvised replacement can create pressure, flammability, electrical, warranty and safety problems. Do not choose a retrofit from a product listing alone. Refrigerant compatibility, equipment design, operating pressure, safety standards, technician training and local rules all have to be checked.
New purchasing decisions will matter more as manufacturers redesign equipment for lower-GWP refrigerants and changing supply conditions. A correctly sized, well-installed and efficient unit can reduce electricity demand throughout its life, not merely comply with a refrigerant rule.
Which refrigerant is climate-friendly?
There is no single refrigerant answer that fits every room air-conditioner, chiller, cold chain or industrial system. The relevant choice combines global-warming potential with safety, pressure, component compatibility, efficiency, availability and the skills needed to install and recover it.

- Lower GWP: Reduces the climate impact of refrigerant released during manufacture, use or disposal.
- Equipment efficiency: Determines how much electricity the system consumes over its operating life.
- Safety: Refrigerant properties can affect flammability, toxicity, pressure and required installation practices.
- Serviceability: Leak detection, recovery and charging require trained technicians and suitable equipment.
- System fit: The refrigerant must be approved for the specific compressor, heat exchanger, controls and operating conditions.
That is why “low-GWP” alone is not a sufficient purchasing or retrofit instruction. India’s transition requires refrigerants and equipment to be evaluated together.

Are energy-efficient air-conditioners worth it?
Efficiency is the second half of the Kigali opportunity. UNEP’s India Cooling Action Plan set 20-year goals covering buildings, appliances, transport, cold chains and industry. Its stated 2038 goals are up to 25% lower cooling demand, 25–30% lower refrigerant demand and up to 40% lower cooling-energy requirements.
UNEP also reported that, if average room-air-conditioner efficiency improves by 6% each year, India could save more than 64 TWh of electricity annually by 2030. That is a modeled potential, not a measured national result. The cited analysis estimated cumulative consumer benefits of up to US$25 billion under that efficiency scenario; this too is a projection rather than money already saved by households.
For a buyer, the practical test is lifecycle cost:
- Compare the official efficiency information available for units of the capacity you actually need.
- Choose a correctly sized system; an oversized unit can cost more without delivering proportional comfort.
- Use qualified installation so airflow, insulation, drainage and refrigerant charge are correct.
- Keep filters, coils and outdoor-unit airflow clear, and arrange leak checks when performance changes.
- Plan end-of-life recovery instead of venting refrigerant during removal.
Purchase price is only one part of the decision. Electricity use, maintenance, expected service life and the availability of trained technicians determine the longer-term cost.

Passive and low-energy measures
- External shading and appropriate window design can limit solar heat gain.
- Insulation and a better building envelope reduce the heat that mechanical systems must remove.
- Fans can extend comfort at higher thermostat settings and reduce compressor runtime.
- Thermal storage and district systems can shift or centralize cooling loads in suitable buildings.
These measures do not eliminate the need for air-conditioning in India’s hottest conditions. They reduce the size, runtime and peak demand of mechanical equipment, making the refrigerant transition easier for both households and the power system.

India’s Ozone Cell maintains the Montreal Protocol regulatory framework and issues quota-related orders. Under the ODS Rules and amendments, using HCFCs to manufacture all new equipment has been prohibited since 1 January 2025.
HCFC phase-out and HFC phase-down are different policies. HCFCs damage the ozone layer and are being eliminated from new-equipment manufacturing. HFCs generally do not deplete ozone but can cause substantial warming, so Kigali limits their production and consumption over time.
Recommended Free Tools
The government’s stated implementation approach includes a national HFC strategy, consultation 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 the infrastructure and policy directions needed for implementation; they do not establish that every product category, quota or downstream rule has already completed its transition.

Why technicians and the electricity grid matter
Refrigerant policy succeeds only when equipment can be installed, repaired, recovered and eventually disposed of correctly. India will need technicians who understand new refrigerant properties, safe charging, recovery, leak detection and the relevant electrical and ventilation requirements. Poor servicing can erase the expected climate benefit through leaks, unsafe conversions or inefficient operation.
Efficiency also affects grid planning. Cooling demand rises during hot periods, precisely when electricity systems are under stress. Lower-load buildings, efficient appliances and alternatives such as fans or thermal storage can reduce peaks while maintaining essential cooling for health, work, food and medicines.
How does cooling affect India’s climate goals?
Cooling is both an adaptation need and an emissions challenge. As heat intensifies and incomes rise, India needs cooling for day-to-day functioning, hospitals, food preservation, medicines and productivity. Benjamin Hickman, a UN Environment technical advisor in India, described the practical reality: “Living in India you quickly understand the importance of keeping cool for your health and day-to-day functioning.”
The climate outcome depends on the whole system: lower-GWP refrigerants, efficient equipment, buildings that resist heat, sensible demand, reliable electricity and competent servicing. Choosing only a refrigerant without improving efficiency leaves large electricity savings unused. Buying efficient equipment without leak prevention leaves direct refrigerant emissions unresolved. Passive design without safe access to essential cooling can undermine health and comfort.
India’s 2028 freeze and later milestones provide a timetable, but the decisive work happens before and between those dates: manufacturers redesign products, regulators operate licensing and reporting systems, builders reduce cooling loads, utilities prepare for peaks and technicians gain the skills to handle new equipment. That systems approach is what will determine whether India’s rapidly expanding cooling market supports its climate goals or makes them harder to reach.
