Can India cool down without heating up? Experts Explain why sustainability is key

The core issue presented is a negative feedback loop: the means of adapting to extreme heat (air conditioning) exacerbates the underlying cause (climate change). Conventional cooling systems rely on hydrofluorocarbons (HFCs), which, while not ozone-depleting like their predecessors (CFCs), are potent greenhouse gases with a high Global Warming Potential (GWP)—meaning they trap significantly more heat than CO2. This highlights India's commitments under the Kigali Amendment to the Montreal Protocol. Under this international treaty, India must phase down HFC consumption, starting with a freeze in 2028 and culminating in significant reductions by 2047. This transition necessitates the adoption of alternative, low-GWP refrigerants (like R-290 or ammonia). For UPSC, understanding the distinction between ozone-depleting substances and greenhouse gases, and the specific mandates of the Kigali Amendment, is crucial for Prelims. Mains questions could focus on the challenges India faces in balancing developmental needs (cooling access) with international climate commitments.

The rising cooling demand poses a significant challenge to India's energy security and grid infrastructure. The article notes peak power demand hit a record 270.8 GW in May 2026 (a projected figure in the source text, though recent years have seen similar peaks driven by cooling). This surge, concentrated during hot evenings, forces reliance on readily dispatchable power sources, often coal, contradicting decarbonization goals. The economic imperative is not to restrict cooling, which is essential for labour productivity and health, but to manage peak load demand. The article suggests integrating cooling into power-sector planning through demand-response strategies (where consumers adjust usage based on grid signals or pricing) and time-of-day pricing (charging more during peak hours to incentivize shifting usage). This relates directly to GS-3 topics on infrastructure, energy, and the challenges of integrating renewable energy into the grid. The Bureau of Energy Efficiency (BEE) and its star-rating program play a critical role here in driving appliance efficiency to reduce the overall energy burden.

The article critiques the siloed approach to cooling and advocates for the holistic strategy proposed in the India Cooling Action Plan (ICAP). Launched in 2019, the ICAP is the first of its kind globally, treating cooling as a cross-sectoral requirement impacting buildings, cold chains, agriculture, and health. The governance challenge lies in policy implementation. Currently, appliance efficiency and the transition to new refrigerants are often managed independently. Effective governance requires aligning these efforts with urban planning and building codes. The article emphasizes passive cooling—designing buildings to reduce the need for mechanical cooling through better ventilation, shading, and cool roofs. This requires integrating thermal comfort standards into public housing schemes like the Pradhan Mantri Awas Yojana and updating municipal building bye-laws. For Mains, candidates should be prepared to discuss the ICAP framework and suggest ways to overcome implementation bottlenecks through coordinated action across ministries (Environment, Power, Housing & Urban Affairs).
