The most commonly used variant in homes is known as
chlorodifluoromethane (R-22).
These refrigerants were identified as feasible alternatives for replacement of R-22 (
chlorodifluoromethane), a refrigerant that was popular for these applications.
Among other items, duties on Mineral waters, Calcium Carbide, Hydrogen peroxide, Razors, Safety Blades and
Chlorodifluoromethane are increased by 5-10 per cent.
In 2016, there was 89 tonnes of refrigerants in total, including R11 (trichlorofluoromethane), R12 (dichlorodifluoromethane), R13 (chlorotrifluoromethane), R22 (
chlorodifluoromethane), R114 (dichlorotetrafluoroethane), R125, R134a, R141b, cyclopentane, isopentane, propane, and butane.

An important example of such a data set is the global distribution of species like
chlorodifluoromethane, or HCFC-22, which is being phased out under the Montreal Protocol on Substances that Deplete the Ozone Layer.
(85.) See, e.g., Wara, supra note 17, at 1779-80 (explaining that adipic acid and
chlorodifluoromethane industries, which have bad environmental impacts, have earned a large number of credits).
The Montreal Protocol, the international agreement that phases out ozone-depleting substances, requires the end of
chlorodifluoromethane production by 2020 in developed countries and 2030 in developing countries.
Chemicals: Asbestos, benzene, bis(2-ethylhexyl) phthalate, bisphenol A epoxy resins, boron and its compounds, butyl benzyl phthalate, di-n-butyl phthalate,
chlorodifluoromethane, chromium and trivalent chromium, cobalt and its compounds, water-soluble copper salt (excluding complex salt), dichloromethane, dioxins, ethene, ethylbenzene, ethylene glycol, hydrazine, hydrogen fluoride and its water-soluble salts, lead and its compounds, manganese and its compounds, molybdenum and its compounds, piperazine, polyoxyethylene alkyl ethers, silver and its water-soluble compounds, tetrachloroethylene, toluene, 1,3,5-trimethylbenzene, xylene
The ban will apply to credits from projects which destroy two industrial gases: trifluoromethane (HFC-23), a by-product of
chlorodifluoromethane (HCFC-22), a refrigerant in air conditioners and refrigerators, and nitrous oxide (N2O) from adipic acid production used in the manufacture of nylon.
