Over 90 percent of all new cars are equipped with air conditioning systems. They provide pleasant indoor temperatures and can enhance driving safety, especially in the summer. What most drivers do not know: The currently used refrigerant is extremely harmful to the climate. And for another reason air conditiong systems are anything but environmentally friendly: MAC systems are powered by the engine and increase the vehicles’ fuel consumption by up to 2 litre per 100 km.

The Deutsche Umwelthilfe e.V. (German Environmental Aid Association) and its partner Verkehrsclub Deutschland e.V. (German Traffic Association) want to press ahead the introduction of natural refrigerants and efficient air conditioning technology. Our campaign addresses several target groups: young driver and car user find important background information in our publications. We offer our exhibition to local authorities, fairs or other public places as a loan. To share professional information about sustainable air conditioning technologies, we organise expert talks and workshops with fleet operators, companies, research institutions and political decision makers.

Also as a consumer you can do something to reduce the environmental impact of MAC systems:
