Environmental Information

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2022 Audi SQ5, 2022 Audi Q5 e, 2022 Audi Q5, 2021 Audi SQ5, and 2021 Audi Q5 e. However, it is still accessible from the selected car via links, so may be relevant.

Since roughly 1992, the air conditioning systems of newly manufactured cars have been successively converted to refrigerant R134a. This refrigerant does not contain chlorine and does not deplete the ozone layer.

Until roughly 1992, refrigerant R12 was used for air conditioning systems. Due to its chlorine atoms, this CFC has a high potential for depleting the ozone layer as well as a tendency to increase the greenhouse effect.

Conversion programs are available for old existing systems filled with the ozone-depleting substance R12. Refer to Repair Manual for A/C Systems with Refrigerant R12 (this repair information is only available in hard copy).

The greenhouse potential of R134a (Global Warming Potential = GWP) is approximately 1400, for this reason the European commission has committed that from 01/01/2017 no vehicles with this can newly be brought into the market. Refer to REFRIGERANT R134A ENVIRONMENTAL INFORMATION . For this reason from 2016 for new vehicles a refrigerant with a GWP smaller than 150 in introduced (for example the refrigerant R1234yf with a GWP less than 5).

For environmental protection reasons, refrigerants must not be released into the atmosphere. For laws and regulations. Refer to LAWS AND REGULATIONS .
