The Kigali Countdown: India’s High-Stakes Challenge of Sustainable Cooling
A decade after the landmark amendment to phase down HFCs, India faces a dual challenge: meeting the cooling needs of a billion people while transitioning from potent greenhouse gases, a task critical to its climate goals and energy security.
What problem did the Kigali Amendment solve?
The Montreal Protocol is widely regarded as one of the most successful environmental treaties in history. It orchestrated the global phase-out of chlorofluorocarbons (CFCs) and other ozone-depleting substances, putting the stratospheric ozone layer on a path to recovery. This success, however, had an unintended consequence. Hydrofluorocarbons (HFCs), introduced as the primary, ozone-safe alternative to CFCs in air conditioners and refrigerators, were found to be super-potent greenhouse gases. Unchecked, the growing use of HFCs, driven by rising global demand for cooling, threatened to undermine climate action. The Kigali Amendment was negotiated to address this specific gap, using the proven legal and institutional framework of the Montreal Protocol to phase down HFCs. According to the UN-backed Scientific Assessment of Ozone Depletion, full implementation of the amendment is projected to prevent 0.3°C to 0.5°C of global warming by 2100.
What are India's specific obligations?
As a developing country, India is part of 'Group 2' under the amendment, which provides a more flexible transition timeline. For comparison, developed nations began their phase-down in 2019, while other developing nations like China have a 2024 freeze date. India ratified the amendment in August 2021, committing to a four-step phase-down schedule. The first deadline is 2028, when India must freeze its HFC production and consumption at a baseline level calculated from its 2024-2026 average levels, plus 65% of its hydrochlorofluorocarbon (HCFC) baseline. Following this freeze, the country must achieve a 10% reduction by 2032, 20% by 2037, 30% by 2042, and an 85% reduction by 2047. This gradual “phase-down,” rather than a complete “phase-out,” allows for continued HFC use in applications where viable alternatives are not yet available. The MoEFCC is tasked with developing a national strategy for this transition by 2026.
