German safety authority UBA wants another two years extension to MAC Directive so carmakers can jump straight to CO2
The German safety authority UBA has told the Reuters news agency that it has asked the European Commission for a two year extension to the MAC Directive so that its carmakers can develop a CO2 alternative.

The news follows hot on the heels of a letter from the Commission to the German authorities saying it can find no grounds for an extension to the Directive, which requires carmakers to use a gas with a GWP under 150. Currently the only useable refrigerant that meets this requirement is HFO 1234yf, which Daimler and other German carmakers have refused to use because they contend it is flammable in a head-on collision.
