EU regulations are most often never eaten as hot as they are being served. Should we wait and see what happens and worry about the DPP later when requirements and standards will be defined in more detail?

That depends on your brand’s ambition and aspiration towards Brand Integrity. We are of the opinion that – even without the EU DPP regulation compliancy aspect – every brand should be intrinsically motivated to do the right thing, for people and the planet, and gain brand integrity recognition at the same time. Being an early mover brings you the benefit of having the concept, the logic, and the flow in place that serves your brand's consumer (and other stakeholders) use cases. As soon as the EU adds particular requirements to the DPP, you can simply include them in your existing concept.
