Today, designers can no longer ignore the environmental impact of the products and services they design, or help to design. With circular design, they now have the conceptual framework and tools to implement responsible design and thus contribute to a more sustainable future. The Meadows Report published by MIT in 1972 was the first study to explain the consequences of pursuing an economic model of infinite development in a world with finite resources. But it is only now, 50 years later, that awareness is growing and attitudes are beginning to change, both in civil society and in companies.
