I'm writing an academic paper in the field of material science and was trying to find working guidelines to define product sustainability.
In particular, I was trying to see if, within the EU, there are laws defining the specific standards a product must meet to be considered 'sustainable' (I've read the European Commission has presented policies to regulate sustainable consumption and production), but I don't know how to navigate EU law nor which organ is responsible for enforcing these regulations, so I haven't been able to find a list of criteria for product sustainability.
Does anyone know what these criteria are or how I can find them?
