News

  • By 2022, India is expected to have one-fourth of the world’s air conditioning units, and the risks to climate from this could be immense, according to a report.

Refrigerants are the most harmful

  1. The refrigerants (coolants) used for cooling are the major contributors to global warming.
  2. If left unchecked, they could cause global temperatures to rise by 0.5 degrees Celsius.
  3. A technology solution that could help to reduce the impact by one-fifth and ensure that air conditioning units use 75% less electricity is the need of hour.
  4. A technology solution would significantly reduce the burden on electricity grids and also save ₹109 trillion ($ 1.5 trillion).

HFCs

  1. Hydrofluorocarbons are organic compounds containing hydrogen, Carbon, and fluorine.
  2. They are commonly used as substitutes for Ozone depleting substances like Chlorofluorocarbons (CFCs) and are used in refrigerators and air-conditioners.

Phasing out HFCs

  1. In 2016, India was a signatory to Kigali Agreement with 107 countries to “substantially phase” out hydro fluorocarbons (HFC), by 2045.
  2. This move was aimed to prevent a potential 0.5 C rise in global temperature by 2050.
  3. HFCs are a family of gases that are largely used in refrigerants at home and in car air-conditioners.
  4. India, China, the United States and Europe have committed themselves to reducing the use of HFC by 85% by 2045.
