The Kigali Amendment to the Montreal Protocol completes ten years in 2026. Adopted in October 2016, the amendment marked an important evolution in global environmental governance by bringing hydrofluorocarbons (HFCs)—powerful greenhouse gases widely used in refrigeration and air-conditioning—under a legally structured phase-down framework. Kigali Amendment at 10
For India, the anniversary comes at a particularly important moment. Rising temperatures, urbanisation, increasing household incomes and wider access to air-conditioning are rapidly expanding the country’s demand for cooling. According to the material provided, the International Energy Agency projects that India’s cooling demand could more than double by 2035 under current policy settings. The challenge is therefore much larger than merely replacing one refrigerant with another: India has to make cooling affordable, energy-efficient and environmentally sustainable. Kigali Amendment at 10
Why Is the Kigali Amendment Important in 2026?
The Kigali Amendment was adopted on 15 October 2016 at Kigali, Rwanda, during the 28th Meeting of the Parties to the Montreal Protocol. Its parent agreement, the Montreal Protocol on Substances that Deplete the Ozone Layer, dates back to 1987. Kigali Amendment at 10
The primary purpose of the Kigali Amendment is to phase down the production and consumption of HFCs. These gases became widely used as replacements for ozone-depleting substances such as chlorofluorocarbons (CFCs), because HFCs generally do not damage the stratospheric ozone layer. However, many HFCs have a very high Global Warming Potential (GWP) and therefore contribute significantly to climate change. Kigali Amendment at 10
This makes Kigali a significant bridge between the earlier ozone-protection regime and contemporary climate policy.
Prelims takeaway: The Montreal Protocol originally targeted ozone-depleting substances, while the Kigali Amendment specifically targets HFCs because of their global-warming impact. HFCs generally do not deplete the ozone layer. Kigali Amendment at 10
Why Are HFCs a Climate Concern?
- First, certain HFCs have a high Global Warming Potential, meaning that per unit of mass they can trap considerably more heat than carbon dioxide.
- Second, their use is increasing because the demand for air conditioners, refrigerators and other cooling equipment is expanding.
- Third, refrigerants can escape through leakage during installation, servicing, maintenance, accidents or disposal.
- Finally, cooling appliances also create indirect emissions. Air conditioners and refrigerators require electricity; where electricity comes from fossil-fuel-based generation, greater cooling demand can also increase carbon-dioxide emissions. Kigali Amendment at 10
- This creates two distinct dimensions of the cooling problem:Direct emissions come from refrigerants such as HFCs. Indirect emissions arise from the electricity needed to operate cooling equipment.
- Effective climate policy therefore has to deal with both refrigerant choice and energy efficiency.
How Much Global Warming Could the Kigali Amendment Prevent?
According to the UNEP Ozone Secretariat figures cited in the source, full implementation of the Kigali Amendment could avoid approximately 0.3°C to 0.5°C of global warming by 2100. Kigali Amendment at 10
The climate benefit arises primarily from preventing future emissions of high-GWP HFCs and encouraging the shift towards refrigerants with lower warming potential.
However, even larger benefits are possible when refrigerant transition is combined with higher energy efficiency in cooling equipment. More efficient air conditioners require less electricity for the same cooling output, thereby reducing emissions from power generation as well. Kigali Amendment at 10
This is why sustainable cooling must be treated as a combined refrigerant + energy-efficiency challenge.
Why Has Cooling Become Central to India’s Climate Challenge?
India’s cooling demand is being shaped by several long-term structural changes.
Rising temperatures and heatwaves: Greater frequency and intensity of extreme heat make cooling increasingly important for public health, workplace productivity and human comfort. Kigali Amendment at 10
Rapid urbanisation: Dense construction, concrete surfaces and limited greenery intensify the urban heat island effect, raising the cooling requirements of Indian cities. Kigali Amendment at 10
Rising household incomes: More households are expected to purchase air conditioners, while demand is also increasing in commercial buildings, hospitals, transport systems and cold-chain infrastructure. Kigali Amendment at 10
Growing electricity demand: The source notes that in June 2026 the IEA reported cooling to account for slightly more than 10% of India’s annual electricity demand. On hot summer nights, air conditioners can account for as much as one-third of electricity consumption. Kigali Amendment at 10
This means that cooling policy is no longer merely an environmental issue. It is also an issue of energy security, power-system planning, public health, affordability and urban development.
India’s Obligations Under the Kigali Amendment
India ratified the Kigali Amendment on 27 September 2021. As a developing country, India follows a phased schedule that provides time for technological adaptation and industrial transition. Kigali Amendment at 10
India’s HFC phase-down schedule is:
| Year | Requirement |
|---|---|
| 2028 | Freeze HFC consumption at the applicable baseline level |
| 2032 | 10% reduction |
| 2037 | 20% reduction |
| 2042 | 30% reduction |
| 2047 | 85% reduction |
These reductions are measured against the applicable Kigali Amendment baseline, not against the immediately preceding year’s level of consumption. Kigali Amendment at 10
Implementation will require a combination of regulation, industrial investment, improved refrigerant management and adoption of alternatives with lower global warming potential. Kigali Amendment at 10
India Cooling Action Plan: The Domestic Policy Framework
India’s principal domestic policy framework in this area is the India Cooling Action Plan (ICAP).
ICAP was launched in March 2019 by the Ministry of Environment, Forest and Climate Change. It provides an integrated framework for addressing cooling requirements across sectors over a 20-year period from 2017–18 to 2037–38. Kigali Amendment at 10
Its stated targets include:
- Reducing cooling demand by 20%–25% by 2037–38.
- Reducing refrigerant demand by 25%–30% by 2037–38.
- Reducing cooling-energy requirements by 25%–40% by 2037–38.
It also emphasises technician training and certification, research and development, low-GWP refrigerants and energy-efficient cooling technologies. Kigali Amendment at 10
An important exam point is that these are targets, not reductions that have already been achieved. ICAP is significant because it explicitly addresses both direct refrigerant emissions and indirect electricity-related emissions. Kigali Amendment at 10
What Are the Major Challenges for India?
India’s transition towards sustainable cooling is likely to involve several interconnected challenges.
- Affordability versus sustainability: Cooling is increasingly becoming essential during severe heat, particularly for vulnerable populations. Cleaner cooling technologies cannot become so expensive that lower-income households are excluded from access. Kigali Amendment at 10
- Technological transition: Manufacturers may need to redesign cooling equipment for alternative refrigerants. Some alternatives also require new safety standards, technical knowledge and servicing practices. Kigali Amendment at 10
- Electricity demand and grid stress: Rapid growth in air-conditioner use can sharply increase electricity demand during hot evenings and nights. Grid management and efficient appliances therefore become integral to climate policy. Kigali Amendment at 10
- Refrigerant leakage: Poor installation, inadequate servicing and unsafe refrigerant handling can substantially reduce the climate benefit of cleaner cooling technologies. Recovery, recycling and environmentally sound disposal are therefore critical. Kigali Amendment at 10
- Financing: Smaller manufacturers and servicing businesses may face additional costs in adapting to new technologies. Financial and technical assistance can make the transition more viable. Kigali Amendment at 10
How Can India Promote Sustainable Cooling?
India’s cooling transition has to extend beyond refrigerant replacement.
- Improve energy efficiency: Stronger minimum energy-performance standards and efficient appliances can reduce the electricity needed for cooling. Kigali Amendment at 10
- Promote low-GWP refrigerants: Suitable low-GWP and natural refrigerants can reduce direct climate emissions, provided safety and application-specific requirements are properly addressed. Kigali Amendment at 10
- Expand passive cooling: Building design can substantially lower cooling demand. Shading, insulation, reflective roofs, ventilation and climate-responsive architecture can reduce heat gain and dependence on mechanical air-conditioning. Kigali Amendment at 10
- Improve refrigerant management: Technician training, leak detection, refrigerant recovery, recycling and safe disposal need to become integral parts of the cooling ecosystem. Kigali Amendment at 10
- Support domestic manufacturing and innovation: India can encourage research and production of energy-efficient equipment and alternative refrigerants, while assisting smaller firms with transition costs. Kigali Amendment at 10
- Use international support: The Montreal Protocol’s Multilateral Fund assists eligible developing countries with agreed incremental implementation costs, supporting technology transfer, institutional capacity and industrial transition. Kigali Amendment at 10
Kigali Amendment and the Larger Climate-Policy Lesson
The Kigali model offers a useful lesson in international environmental cooperation: a specific pollutant can be addressed through clear reduction schedules, monitoring, financial support and technology transition.
However, the same policy cannot simply be copied for every climate pollutant. Methane, for example, requires interventions in fossil-fuel operations, agriculture and waste, while black carbon is linked to incomplete combustion and household or industrial energy use. Kigali Amendment at 10
The broader principle is that global climate cooperation works best when combined with sector-specific domestic policies.

Mains Practice Question
“The transition to sustainable cooling is essential for reconciling India’s developmental needs with its climate commitments.” Discuss with reference to the Kigali Amendment and the India Cooling Action Plan.
A good answer should connect rising heat and cooling demand, HFC phase-down, electricity consumption, energy efficiency, passive cooling, low-GWP refrigerants, affordability, technological transition and ICAP targets.
Conclusion
The tenth anniversary of the Kigali Amendment is not merely a milestone in international environmental diplomacy. For India, it raises a much larger development question: how can hundreds of millions of people gain access to adequate cooling without locking the country into unsustainable electricity use and greenhouse-gas emissions?
The answer lies in combining low-GWP refrigerants, efficient appliances, climate-responsive buildings, better refrigerant management, domestic innovation and affordable access to cooling. Kigali Amendment at 10
India’s real objective, therefore, should not simply be to cool more spaces, but to deliver sustainable cooling for all. Kigali Amendment at 10
