In a multi-part video series, we – as an ecologist and a lawyer – provide sound answers to pertinent questions about everyday business life.


We answer questions such as:

  • When is it considered greenwashing?

  • How do you communicate transparently?

  • What is the function of a digital product passport?

  • What do sustainably designed products have to do with product certifications?

  • What are the benefits of sustainable procurement?

  • How can sustainable procurement be integrated into companies?
