Significance: Aims to prevent between 0.3°C to 0.5°C of global warming by 2100, crucial for achieving the Paris Agreement targets of keeping temperature rise below 2°C.
2. Background of the Montreal Protocol:
Initial Agreement: Established in 1987 to phase out ozone-depleting substances (like chlorofluorocarbons, CFCs).
Ozone Layer Recovery: Nearly 99% of controlled substances eliminated; the layer is recovering.
3. Impact of HFCs:
Warming Potential: HFCs can have a warming impact hundreds to thousands of times greater than CO2.
Rapid Growth in Demand: With increasing global temperatures, demand for cooling solutions is significantly rising, especially in developing countries like India.
4. India's Responsibilities under Kigali:
Ratification Year: India ratified the amendment in 2021.
Production Freeze: HFC production and consumption must be capped at an agreed baseline by 2028.
Reduction Timeline:
10% reduction by 2032.
85% reduction by 2047.
Current Demand: Cooling accounts for over 10% of annual electricity demand, with projections of more than doubling by 2035.
5. Economic and Environmental Considerations:
Efficiency Improvements: Enhancements in cooling efficiency can significantly reduce electricity consumption and emissions.
Multilateral Fund: Established in 1991 to assist developing countries in transitioning away from HFCs, it has helped avoid 50 billion tonnes of CO2 emissions by funding technology changes.
6. Global Participation and Challenges:
Current Status: As of October 2026, 175 parties have joined the Kigali Amendment.
Next Steps: Focus on refrigerant recovery and safe disposal during appliance servicing and disposal; revitalization of "Friends of the Kigali Amendment" coalition.
7. Potential for Expansion:
Model for Other Pollutants: The success of the Kigali Amendment could inform future agreements to phase down other short-lived climate pollutants (SLCPs) like methane and black carbon, which also significantly impact climate.
8. Future Directions for Effective Policy:
Binding Agreements: There is a proposal for binding international agreements akin to the Montreal Protocol to address methane emissions globally, especially from oil and gas sectors.
Sector-Specific Solutions: Various sources of super pollutants would require tailored obligations to effectively reduce emissions and support compliance.
Conclusion:
The Kigali Amendment represents a key international effort to mitigate climate change effects by regulating substances that contribute to global warming. Its success is closely linked to ongoing participation, technological advancements, and cooperative financial mechanisms aimed at supporting developing nations in their transition to more sustainable cooling solutions.
Promoted by the Council of Scientific and Industrial Research-National Environmental Engineering Research Institute (CSIR-NEERI), which forecasts a PM10 reduction of 45%-60% with the new generation.
However, actual pollution reduction gains may diminish with increased usage of these "cleaner" options.
Challenges in Implementation and Regulation
Enforcement Issues:
The Commission for Air Quality Management has reported unauthorized sales of QR codes used for verifying manufacturer legitimacy.
Lack of testing facilities in Delhi complicates enforcement of the regulations.
Past challenges included police difficulties in distinguishing green crackers from conventional ones during 2018-2019.
Implications for Public Health and Policy
There is a collective need for manufacturers to transition to the formal sector and ensure regulations are practiced effectively.
Public awareness on the health impacts of fireworks must be enhanced to mitigate air and noise pollution levels during festive seasons.
Conclusion
The interplay of legal decisions, pollution metrics, and regulatory challenges highlights the ongoing struggle in Delhi and the NCR, where public health, environmental sustainability, and regulatory enforcement converge amidst the festive use of fireworks.
The village has employed a security guard to patrol the area, marking the second instance in ten years where such a measure has been taken to deter the animals.
Residents have attempted various methods, like laying thorny twigs on roofs, to protect their property from langur intrusions.
Health and Safety Issues: Residents report physical injuries and safety concerns due to langur interactions. For instance, a 65-year-old resident injured her foot while trying to escape a langur encounter.
Contributing Factors:
Experts indicate habitat loss due to agricultural expansion as a primary reason for increased human-animal conflicts. The destruction of natural bunds and trees has forced langurs into human habitats as they seek food and shelter.
Effective solutions suggested include providing safe habitats for langurs to encourage them away from human settlements.
Forest Department's Role:
Forest officials have verified claims of frequent complaints and interventions but express that numerous villagers do not consult or inform them before employing personal guards.
The Superintendent of Police emphasized that hiring guards requires the district collector's permission, which was not obtained in this case.
Current Status: At present, the village continues to grapple with the langur issue, and frustration among residents is growing due to a perceived lack of effective solutions and support from authorities. Many feel abandoned in addressing the persistent wildlife conflict.
This case illustrates the complexities of human-wildlife interactions, the importance of wildlife protection laws, and the necessity for community cooperation with regulatory bodies for sustainable coexistence.
