Buses are eco-friendly means of transport, nevertheless their climate performance can be increased still further. Today’s mobile air conditioning systems in buses still use the refrigerant tetrafluoroethane (R134a), a greenhouse gas with a 1,430 times higher impact to the climate than carbon dioxide. There is a climate friendly alternative: Some city buses already use CO2 air conditioning systems. read more
Rail vehicles include local and long-distance trains, suburban fast trains, underground trains and trams. The energy for heating is provided electrically or with diesel fuel. Mobile air conditioning systems in rail vehicles are usually charged with HFC refrigerants. HFCs, or hydrofluorocarbons, are very potent greenhouse gases. read more
An EU directive has banned the use of fluorinated refrigerants with a global warming potential of more than 150 in certain mobile air conditioning systems since Jan. 2011. It requires the previously used refrigerant tetrafluoroethane (R134a) to be replaced. Natural refrigerants are considered the best environmental alternative. Climate-friendly alternatives are also available for buses and trains. read more
The UBA’s motto, For our environment (“Für Mensch und Umwelt”), sums up our mission pretty well, we feel. In this video we give an insight into our work.
