Eventually, it agreed to freeze the use of HFC in 2028, four years later than its peer club countries of China, Brazil and Africa, and by 2047, two years after they do, to achieve a maximum reduction. In contrast, India has asked producers of HFC 23 – a by-product of another chemical used in the production of refrigerant gas and contributing surprisingly significantly to global warming – to register it and throw it away at its own expense. This decision is of particular importance considering that cold and climate technologies are increasing in India with an increase in incomes, resulting in an increase in HFC releases to the atmosphere. The need for this amendment is the result of the 1987 Montreal Protocol process, which controls ozone-depleting substances. .
