It is sim­ple math­e­mat­ics. We can only emit 990 bil­lion tonnes of CO2 be­tween 2012 and 2100 if we want to keep the rise of global tem­per­a­ture to less than 2 de­grees. HFC phase-down and a di­rect tran­si­tion to nat­u­ral re­frig­er­ants can help elim­i­nate 5-8 bil­lion tonnes of CO2 e.

Adopt­ing AC tech­nol­ogy that is both cost-ef­fec­tive and en­ergy-ef­fi­cient could save over 192 ter­awatt-hours per year by 2020—the same amount of en­ergy as pro­duced by 64 medium-sized power plants.

Ap­pli­ances are rated with en­ergy stars based on power ef­fi­ciency. En­ergy ef­fi­ciency of an ap­pli­ance is im­proved by 10-30 per cent with the use of low GWP al­ter­na­tives. Each star rat­ing sig­ni­fies a re­duc­tion in power con­sump­tion by around 6-8 per cent. For ex­am­ple, a 1-star re­frig­er­a­tor will con­sume nearly 750 units (kWh) of elec­tric­ity a year. That comes to over two units a day. Whereas a 5-star rated re­frig­er­a­tor will con­sume only a lit­tle over 300 units a year, less than one unit a day. There­fore, low GWP al­ter­na­tives will have cli­mate and en­ergy ben­e­fits.
