An EU directive has banned the use of fluorinated greenhouse gases with global warming potential exceeding 150 in mobile air conditioning systems since January 2011. CO2 used as a refrigerant is an alternative. An UBA official car had used a CO2 mobile air conditioning system from 2009 to 2017. Since October 2016, first cars with CO2 air conditioning systems have been offered. read more

Mobile air conditioning with fluorinated refrigerants

The photo shows that the fluorinated refrigerant 1234yf burned during the laboratory test.

An EU directive bans the use of fluorinated greenhouse gases with global warming potential exceeding 150 for mobile air conditioning systems in motor vehicles since January 2011. Thus the current refrigerant tetrafluoroethane (R134a) has to be replaced. Tests in laboratory and car showed that the new refrigerant 1234yf selected by car industry can lead to fires. read more

Indicator: Global environmental footprint of consumption

A graph shows the global environmental footprint of household consumption, represented by the indicator’s energy consumption, CO₂ emissions and raw material use. The indicators show the environmental footprint generated by the consumption activities of private households in Germany and abroad

Compared with 2010, energy consumption by private households and associated carbon dioxide emissions decreased slightly overall.Raw material use stagnated at the level of 2010.In its Sustainability Strategy the German government sets the goal of reducing the global environmental footprint of private household consumption in all three areas. read more
