Cradle to Cradle Certificate now in version 5.0 

Sustainability consistently taken to the next level

As one of the first companies in our industry, we have successfully updated the Cradle to Cradle Certified® Material Health Certificate (C2C-MHC) from version 4.1 to the new version 5.0.

With this upgrade, we are sending a clear signal regarding transparency, material health and responsible conduct throughout the entire value chain. At the same time, we are underlining our commitment to working consistently in accordance with the latest standards and actively shaping sustainable developments.

For us, sustainability is not a one-off milestone or a status quo, but a continuous process: taking responsibility, making progress measurable and developing step by step.

We are delighted to take this next step – and to continue actively promoting sustainable solutions in the future.
