• Aircon systems calculated in fuel consumption

    The EU should move quickly to replace synthetic cooling systems in car air conditioning systems with a CO2-based approach, says one of T&E’s German members DUH.

    As well as concerns over fuel consumption, DUH and other NGOs are concerned about the rising use of aircon systems which use chemicals much more damaging to the environment than CO2.

    DUH’s Jürgen Resch said: “The decision for or against CO2 can no longer be left to car companies. It will have a major influence on the climate performance of hundreds of millions of new cars in Germany, Europe and worldwide.”

    Another German NGO Bund first highlighted this issue in 2004 when the EU first discussed cooling substances for car aircon systems.

    Last month the German car club ADAC calculated how aircon systems can affect fuel consumption. Its test cars found that reducing the car’s temperature from 31C to 22C used between 2.47 and 4.15 litres per 100km.
