Hi 123-steve909,

I don't think it is due to be put in to any new cars yet.

I think it is due to be used in any new models manufactured from 2011.

That is not a refrigerant gas, it is used in camping stoves and portable cooking equipment.

Not the kind of thing I would like to put in a pressurised system at high temperatures.

Low GWP refrigerants like 1234yf only need to be fitted to brand new models manufactured from 2011 and in all new cars from 2017. Some manaufacturers are still considering the use of CO2 as an alternative.

There is a useful website on hfo1234yf recently launched called 1234facts.com

MAC Directive Article 6 Applicable from 1st January 2011

All vehicles type approved after January 2011 cannot be fitted or retrofitted with an air-conditioning system that contain a refrigerant with a GWP higher than 150 (including HFC 134a).

Any vehicles manufactured before January 2017 that have not gone through a type approval process between January 2011 and January 2017 can be manufactured with an air-conditioning system that contains a refrigerant with a GWP higher than 150 (including HFC 134a).

All vehicles factory fitted with an air-conditioning system designed to contain a refrigerant with a GWP higher than 150 (including HFC 134a) can continue to be refilled with that refrigerant after 1st January 2017.

Up until 2017 all other vehicles can be retrofitted with air-conditioning systems that contain a refrigerant with a GWP higher than 150 (including HFC 134a) and once retrofitted can continue to be refilled after 1st January 2017.

After January 2017 all vehicles that are manufactured need to be fitted with air-conditioning systems that contain a refrigerant with a GWP less than 150 and no vehicles can be retrofitted with airconditioning systems that take a refrigerant with a GWP higher than 150 (including HFC 134a) after 2017.
