Regulations And Directives

WARNING: This page is about a different car, the 2022 Volkswagen ID.4 and 2021 Volkswagen ID.4. However, it is still accessible from the selected car via links, so may be relevant.

The laws and regulations listed below are applicable in Germany. Different or additional laws and regulations may apply in other countries.
The refrigerant R744 is a naturally occurring substance (carbon dioxide, CO₂ ) with a Global Warming Potential (GWP) of "1".

Numerous laws have been created for the automotive industry, for example at the European level. For example, chemical-climate protection regulations were put into effect on 08/01/2008 in Germany in order to define the European legislation in more detail.

In the European community different regulations have been created for handling refrigerant for example:

Provision (EU) number 1005/2009
Provision (EU) number 2037/2000
Provision EU number 517/2014
Provision (EU) number 706/2007
Provision (EU) number 307/2008
Guideline 2006/40/EU

In Germany different laws have been created for refrigerant for example:

Chemical-climate protection regulations, recycling and disposal law
TRG (technical regulations for compressed gases)

Since the refrigerant R744 is a naturally occurring substance that does not fall under the Chemicals Act, it may be released into the environment and is not subject to the take-back obligation that applies to chemical refrigerants.
The refrigerant circuit is cleaned (flushed) with the chemical refrigerants R134a or R1234yf, which are subject to the Chemical Act. The following applies to these refrigerants:

Maintenance and Repair Work on the A/C System Refrigerant Circuit

Only technicians with verifications of there expertise according to provision (EU) number 307/2008 may perform repair and service procedures on the A/C system refrigerant circuit. (Applies to countries in which these provisions apply, in other countries other regulations or laws may apply.)

The following general information applies:

Operation, repair, decommissioning, take-back obligation

When operating, repairing and decommissioning items that contain chemical refrigerant, allowing the refrigerant to vent into the air is prohibited. This provision does not apply to the naturally occurring refrigerant R744.
Keep records on the amount of chemical refrigerants used during operation and maintenance work so they can be presented to the authorities upon request. A record sheet currently no longer needs to be kept in the EU due to a provision by the European Parliament in 2005. Other provisions may apply in countries that are not members of the EU.
Distributors of the substances and preparations discussed above are obligated to accept these items back after use or to ensure they are accepted by a third party of their choosing.
Maintenance and decommissioning of items containing chemical refrigerants that are named in the legislation Substances and preparations named in this legislation may only be accepted by those with the necessary qualification (expertise) and technical equipment. This does not apply to the naturally occurring refrigerant R744.

Recycling and Disposal Law, Processing and Disposal of Contaminated Chemical Refrigerants and Refrigerant Oil

Observe the current regulations and laws that are in effect in the country.
