Kigali Amendment to the Montreal Protocol and India’s Cooling Challenge

The Kigali Amendment is a legally binding amendment to the 1987 Montreal Protocol. While the original Protocol successfully phased out ozone-depleting substances (CFCs, HCFCs), HFCs—introduced as ozone-friendly substitutes—have very high Global Warming Potential (GWP), sometimes thousands of times that of CO₂. The Amendment therefore focuses on the phase-down (not complete phase-out) of HFCs to complement the Paris Agreement’s temperature goals.

Key Timeline and Differentiation

Adopted: 15 October 2016; entered into force: 1 January 2019.

Common but Differentiated Responsibilities: Developed countries began earlier; most developing countries (Group 1) start cuts from 2024; India, Pakistan, Iran and some Gulf states (Group 2) have later timelines.

India’s commitments (ratified 2021): Freeze at baseline in 2028 → 10% reduction by 2032 → progressive cuts culminating in 85% reduction by 2047 (measured in CO₂-equivalent warming impact).

Why It Matters for India (GS-III Environment + Economy)

India’s cooling demand is projected to more than double by 2035 due to rising incomes, urbanisation, heatwaves and the need for cold chains (food, vaccines, medicines). Cooling already accounts for >10% of annual electricity demand and can reach one-third on hot summer nights. Unchecked HFC growth would lock in high emissions and peak power demand.

The Amendment aligns with the India Cooling Action Plan (ICAP) launched in 2019 by MoEFCC. ICAP’s 20-year goals (to 2037-38) include:

• 20–25% reduction in overall cooling demand,

training of technicians and promotion of low-GWP refrigerants and energy-efficient appliances (linked to BEE star labelling).

Significance for UPSC

Prelims: Direct questions on Montreal Protocol amendments, HFC vs CFC differences, India’s ratification year and freeze/reduction years, linkage with Paris Agreement.

Mains (GS-III): Climate change mitigation co-benefits, energy security, sustainable urbanisation, industrial competitiveness (refrigerant and appliance manufacturing), and balancing development needs with international commitments. Recent context (10th anniversary in October 2026) makes it high-priority current affairs.

Effective implementation requires combining HFC phase-down with energy-efficiency standards, passive cooling in buildings, and refrigerant recovery systems so that rising cooling access does not undermine India’s climate goals.
