Legally verified and certified by an independent warranty mark.
Under the EU EmpCo Directive and the Green Claims Directive, environmental and sustainability claims and their labeling may only be used if they are demonstrable, verifiable, and independently verified. This applies in particular to claims such as:

The ZERKOM® EmpCo testing standard translates the requirements of the EU EmpCo Directive (Empowering Consumers for the Green Transition) into an objective, independent, and verifiable certification and testing procedure for environmental and sustainability claims ("Green Claims").
It is aimed at businesses, authorities, and market participants who wish to verify or demonstrate environmental and sustainability claims in a legally secure, transparent, and traceable manner.
This testing standard serves the objective, independent, and traceable verification of environmental and sustainability claims ("Green Claims") within the meaning of EU Directive (EU) 2024/825 (Empowering Consumers for the Green Transition – EmpCo).
The aim is to provide a concrete and verifiable implementation of abstract legal requirements, thereby creating transparency, comparability, and legal certainty.

With the entry into force of the EU EmpCo Directive (Empowering Consumers for the Green Transition), the market for ecological product information is fundamentally changing. From Sept 27, 2026, environmental and sustainability claims are strictly regulated.
Claims such as "compostable," "biodegradable," "environmentally friendly," or "CO₂ neutral" may only be used in the future if they are supported by independent, verifiable evidence.
For manufacturers, this means:
ZERKOM® is the only government-recognized certification body in Germany and Europe that confirms the "100% compostable" guarantee with an official, verified warranty mark. This type of certification alone fully meets the requirements of the new EmpCo Directive.
ZERKOM® is the solution for the new legal situation. With ZERKOM®, your product receives a recognized seal of approval and permission to continue advertising safely.
EU Law to Restrict Greenwashing
With the entry into force of the new EU law to restrict greenwashing on January 17, 2024, the requirement for clearly recognizable guarantee information and the introduction of a new label for guarantees that go beyond legal warranties was mandated.
The ZERKOM® sustainability seal in the form of a warranty mark is unique and closes the protection gap for quality seals. While conventional quality seals only represent a snapshot at the time of testing, ZERKOM® offers a permanent and legally binding guarantee or warranty for product properties.
Questionable sustainability seals or greenwashing can damage the image in the long term, lead to the loss of customers as well as financial losses and even legal consequences.
The ZERKOM® seal offers companies the opportunity to stand out from the competition with a genuine green sustainability seal and provides advantages for all actors involved – from manufacturers to resellers and end consumers. This leads to positive reporting, consumer approval, and a positive image transfer from ZERKOM®'s uncompromisingly green sustainability seal to the respective company.
Consumers have security for the first time with a sustainability seal that guarantees product properties in a legally binding manner. As the only sustainability seal for 100% compostable products and packaging, ZERKOM® already complies with the new EU directives and thus offers companies planning security for the coming years and laws today.
The Green Dot and the Green Button are already well known. Now there is also the "100% Compostable" mark, made possible by the Trademark Law Modernization Act, which came into force on January 14, 2020. This law created a new trademark category with the "warranty mark." This allows signs to be registered with which a trademark owner assumes the warranty for certain properties of the goods and services of other providers.
In contrast to the origin function of an individual mark, the warranty mark has a guarantee function.
Previously, even objective quality seals could only be protected as a trademark to a very limited extent. The warranty mark closes a protection gap in the registration of such seals.
The "100% Compostable" mark uses this new possibility and offers companies and consumers security through a sustainability seal that guarantees product properties in a legally binding manner.
A warranty mark is a special type of trademark that serves to guarantee certain properties or quality features of goods or services. These marks are not used by the manufacturer of the products themselves, but by an independent body that verifies and certifies compliance with certain standards.
A quality seal is a visible sign (often in the form of a logo) that is applied to products to indicate that they meet the standards set by the warranty mark. Only the holder of the warranty mark has the right to award this quality seal.
Word Mark: A word mark consists of one or more words and serves to distinguish the goods or services of one company from those of other companies.
Fanciful Mark: A fanciful mark is a special type of word mark consisting of an invented word that has no direct meaning (e.g., "Kodak").
In contrast, a warranty mark does not primarily serve to distinguish the origin of products, but to confirm certain quality standards.
The warranty mark "100% Compostable Packaging & Products" guarantees the consumer: Eco-friendliness, Quality control, and Trust.
Certification of 100% compostable packaging & products by ZERKOM® not only offers companies the opportunity to build customer trust, but also demonstrates their commitment to sustainability.
Compostable packaging & products are eco-friendly, reduce waste, and promote sustainable disposal, making them an ideal choice for businesses and consumers who want to protect the environment.
