The Grünes Gas certification was launched in June 2013.
The seal is awarded for gas products when the production, use and distribution of the biogas meet the requirements as set out in the Criteria List.
These include for example:
Biogas must be sourced by environmentally friendly means (it is not permitted to turn precious habitats into monoculture for example).

A strong focus on crop sequencing balance.

It is not permitted to use problematic herbicides and fertilizers from factory farming.

It is not permitted to use genetically engineered organisms in the production process.

Certification requires biogas (biomethane) or sewage gas.
Landfill gas is not accepted.

Primarily, regional raw materials should be used (raw materials carried over distances beyond 50 km are judged negatively).

Gas providers are transparent about the composition of their product (a minimum of 10 % certified biogas).

Conformity of suppliers and providers, producers and power supply companies is verified based on rating system credit points.
Currently, Grünes Gas is the only seal of approval for biogas indicating endorsement by environmental organizations, including consumer information groups.
