In January 2011, the German environmental group DUH and the German automobile club VCD have launched Pro Climate, a campaign alerting consumers about the greenhouse gas potential of chemical refrigerants in car air-conditioning systems and the dangers the potential alternative HFC1234yf might bring. An online survey now invites people to share opinions about the daily use of their A/C.
Air-conditioning systems have become a standard feature in cars. Over 90% of new cars are equipped with A/Cs and most drivers do not understand how they work. Even less consumers know that cars’ A/Cs cause higher fuel consumption and use a highly climate damaging refrigerant, namely R134a. The German environmental group DUH and the German automobile club VCD started in January 2011 the campaign “Pro Climate: efficient car air-conditioning systems with natural refrigerants” that informs consumers about the potential use of CO2refrigerant in mobile air-conditioning as well as the environmental and health concerns related to the new substance under consideration, namely HFC1234yf. The campaign has kicked off in January 2011 simultaneously to the entering into force of the European directive on emissions from air-conditioning systems in motor vehicles (2006/40/EC) also called the MAC Directive. In the effort to mitigate climate warming from mobile air-conditioning, this directive foresees that new types of cars must contain in their A/C units refrigerants with a global warming potential (GWP) of below 150.
