The circular economy impacts all applicative domains and fields. Every activity sector, every industry, and every administration try by different means to initiate actions with the objective of dramatically reducing resource extraction and waste production. To this end, many actions can be taken now without waiting for new technologies or new products. Sustainability can only be achieved through more global approaches such as lifecycle thinking and environmentally conscious product design, which is used in increasingly digital systems. This paper describes why and how international standardization bodies work, so that each country and organization can have tools that aggregate everyone's experience, and so that the environment can benefit from the performance of digital technology and not suffer it as a constraint.
