Siegelklarheit highlights sustainability labels that truly deliver on their promises

More than 230 sustainability labels are on the market. How is anyone supposed to keep track?

In the label directory, you can see which labels are particularly demanding and recommended. You will find labels with overall ratings of "Good choice" or "Very good choice" for quick guidance. If there are multiple evaluated labels in a product group, you can compare them directly.

Missing a label

There can be several reasons:

  • The label cannot be found on consumer products.
  • It does not yet meet Siegelklarheit’s minimum requirements.
  • The label has not provided data for assessment on Siegelklarheit.

New labels are added continuously, and additional product groups (e.g., food) are being included.
