JEL Classification: M21, Q56.Crises that threaten the viability of our planet: climate change, natural disasters and depletion of natural resources have their roots in the way we use materials and goods. Companies need to update their policies as we move into a circular economy and this is a very important transition for the environment. In a circular economy, production and consumption are increasingly based on responsible raw materials and renewable energy, providing a product as a service, long-term products and reused materials.
