Overview
- The Kigali Amendment to the Montreal Protocol aims to phase down hydrofluorocarbons (HFCs), which contribute significantly to global warming despite not directly depleting the ozone layer.
- Rising temperatures, urbanisation and increasing demand for air conditioning are making sustainable cooling a major climate challenge for India.
- India must promote climate-friendly refrigerants, energy-efficient cooling technologies and better refrigerant management to reduce emissions and electricity consumption.
- Financial assistance, technology transfer and international cooperation are essential to ensure an affordable and equitable transition to sustainable cooling, particularly in developing countries.
Why in the News?
The Kigali Amendment to the Montreal Protocol completed ten years, bringing renewed attention to the challenge of meeting the growing demand for cooling while reducing greenhouse gas emissions.
News in Brief
- The Kigali Amendment aims to phase down hydrofluorocarbons (HFCs), which are widely used in air conditioning and refrigeration but have a high global warming potential.
- The amendment was adopted in Kigali, Rwanda, in 2016 and entered into force in 2019.
- The Montreal Protocol has helped eliminate nearly all ozone-depleting substances, contributing to the recovery of the ozone layer.
- India ratified the Kigali Amendment in 2021 and must progressively reduce HFC production and consumption in accordance with the agreed schedule.
What is the Kigali Amendment?
- The Kigali Amendment is an international agreement adopted under the Montreal Protocol to phase down the production and consumption of HFCs.
- The Montreal Protocol was originally agreed upon in 1987 to protect the ozone layer by phasing out ozone-depleting substances such as chlorofluorocarbons (CFCs).
- It has contributed significantly to the recovery of the ozone layer.
- As CFCs were phased out, HFCs became common substitutes in refrigeration and air conditioning.
- Although HFCs do not directly deplete the ozone layer, many have a high global warming potential.
- The Kigali Amendment extends the Montreal Protocol’s climate benefits by addressing these powerful greenhouse gases.
Why are HFCs a concern?
- HFCs are used in air conditioners, refrigerators and other cooling equipment.
- However, when released into the atmosphere, they trap heat and contribute to global warming.
- Some HFCs have a warming impact hundreds or thousands of times greater than that of carbon dioxide over a comparable period.
- The growing use of cooling equipment makes HFC management increasingly important, particularly in countries experiencing rapid urbanization and using temperatures.
How does the Kigali Amendment help prevent global warming?
- Full implementation of the Kigali Amendment could avoid approximately 0.3°C to 0.5°C of global warming by 2100, according to the assessment cited in the article.
- Its climate benefits arise mainly from reducing HFC emissions.
- However, the overall impact depends on effective implementation, compliance and the adoption of suitable alternatives.
- The amendment also supports the objectives of the Paris Agreement, which seeks to limit global warming to well below 2°C while pursuing efforts to restrict it to 1.5°C above pre-industrial levels.
Why has cooling become a major climate challenge?
- The demand for cooling is increasing because of rising temperatures, urbanization, improving living standards and the expansion of commercial and industrial activities.
- Cooling contributes to climate change through two major pathways;
- Refrigerant emissions: HFCs can escape from air conditioners and refrigeration equipment during operation, servicing or disposal.
- Energy-related emissions: Cooling equipment consumes electricity, which can generate carbon emissions when produced using fossil fuels.
- Therefore, replacing high-global warming refrigerants alone will not be sufficient.
- Improving the energy efficiency of cooling equipment is equally important.
- Cooling already accounts for a significant share of electricity demand in India.
- Under current policies, India’s cooling demand is projected to more than double by 2035.
What must India to under the Kigali Amendment?
- India ratified the Kigali Amendment in 2021 and is required to progressively reduce HFC production and consumption according to its agreed schedule.
- India’s approach must address two interconnected challenges; reducing the climate impact of refrigerants and improving the energy efficiency of cooling systems.
- Important measures include;
- Adopting climate-friendly refrigerants: Encourage alternatives with lower global warming potential.
- Improving energy efficiency: Promote energy-efficient air conditioners, refrigerators and commercial cooling systems.
- Supporting technological innovation: Encourage manufacturers to develop affordable and environmentally sustainable cooling technologies.
- Strengthening servicing practices: Reduce refrigerant leakage through proper installation, maintenance, recovery and recycling.
- Promoting sustainable cooling: Integrate cooling requirements into urban planning, building design and electricity planning.
- Switching to alternative refrigerants may require changes in equipment design and manufacturing processes.
- These changes also provide an opportunity to improve the energy efficiency of appliances throughout their operating life.
How can India benefit from energy-efficient cooling?
- Improving cooling efficiency can reduce electricity consumption, lower household expenditure and ease pressure on the power sector.
- The benefits are particularly important during heatwaves, when air-conditioning demand can increase sharply.
- Combining HFC phase-down measures with improved cooling efficiency could substantially increase the climate benefits of refrigerant transitions.
- For India, this approach can help reconcile rising cooling needs with its climate commitments and energy security requirements.
How does the transition affect developing countries?
- Developing countries may face financial and technological challenges when replacing existing cooling equipment and shifting to alternative refrigerants.
- The Multilateral Fund under the Montreal Protocol supports eligible developing countries in meeting their obligations.
- Established in 1990, the fund provides financial and technical assistance for activities such as:
- Converting manufacturing facilities to alternative technologies.
- Training technicians who install and service cooling equipment.
- Building institutional and technical capacity.
- Supporting compliance with agreed phase-down schedules.
- Such assistance is important because the transition must remain affordable while enabling developing countries to meet their environmental commitments.
Can a similar approach address other short-lived climate pollutants?
- The possibility of applying a similar international approach to other short-lived climate pollutants (SLCPs).
- These include;
- Methane: A powerful greenhouse gas released from sources such as agriculture, fossil fuel production and waste.
- Black carbon: Soot produced by incomplete combustion of fuels, including emissions from diesel engines and traditional cooking fuels.
- Hydrofluorocarbons: Industrial gases used mainly in cooling applications.
- Tropospheric or ground-level ozone: A harmful air pollutant formed through chemical reactions involving other pollutants in the atmosphere.
- These pollutants have different sources and environmental impacts.
- However, many have a relatively short atmospheric lifetime compared with carbon dioxide while contributing significantly to near-term warming.
- Reducing their emissions can slow warming in the near-term, complementing long-term efforts to reduce carbon dioxide emissions.
- A common international framework may not be suitable for every pollutant.
- Policies must account for differences in emission sources, national circumstances, implementation costs and the capacity of affected communities.
Why do international climate agreements need differentiated responsibilities?
- International agreements must recognize differences in countries’ development needs and their capacity to control pollution.
- Developed countries generally have greater financial and technological resources, while developing countries may face difficulties financing expensive transitions.
- For instance, measures to reduce methane emissions from cattle can affect small farmers’ incomes and food produciton.
- Similarly, reducing black carbon from traditional cooking practices requires access to cleaner fuels and affordable technologies.
- The Kigali Amendment offers a useful example of how a global environmental agreement can combine binding reduction schedules with financial and technical support for developing countries.
Conclusion
The Kigali Amendment provides an important framework for addressing the climate impact of cooling technologies. For India, the priority is to balance growing cooling needs with energy efficiency, climate-friendly refrigerants and affordable access to cooling. A sustainable cooling transition will require effective implementation, technological innovation and international cooperation.
