This paper analyses public policies concerning sustainability in Brazil, Chile, Colombia, and Mexico; and examines their contribution to the transformation of the productivity practices towards circular economy (CE). The findings allow for a distinction among three fields: renewable energy and energy transition, sustainable production and consumption, and waste management. This paper points out elements for formulation of public policies directed towards CE, such as the need for stability and normative clarity to handle actions from active participators; the creation of taxes and economic/financial incentives to industrial updating processes and making of profit out of externalities; the formation and training of human capital to align business’ goals with sustainable practices; and both the education and sensitization of the population that drive policies dissemination.
