Umwelt-Indikator

Indicator: Energy use and CO₂-emissions of the consumption

A graph shows the direct and indirect energy use and CO2 emissions of private households in 2000, 2005 and from 2007 to 2015. The energy use is divided into five areas of demand.

Energy use in private households has fallen by 7.7 % since 2000.This development can largely be attributed to the reduction in energy consumption in the “living” sector, which has fallen by 12.7 % within the same period.Carbon dioxide emissions in private households show a similar fluctuation pattern to that of energy consumption. read more

Mobile air conditioning with climate-friendly refrigerant CO2

Silver VW Touran in front of the UBA headquarters.

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
