The circular economy is a model of production and use of goods that encourages the re-use, rather than disposal, of as many parts or materials involved in the production of such good. The energy (and associated emissions) associated with the re-use of parts or materials is typically significantly lower than creating them from scratch and their subsequent and therefore a circular economy promotes the mitigation of climate change.
