RT journal article T1 Indicators toMeasure Efficiency in Circular Economies A1 Sánchez Ortiz, Jaime A1 Rodríguez Cornejo, Vanessa María A1 Río Sánchez, Rosario del A1 García Valderrama, Teresa A2 Economía Financiera y Contabilidad A2 Organización de Empresas K1 circular economy K1 indicators K1 efficiency K1 data envelopment analysis AB In this paper, a number of indicators are shown to measure economic efficiency in terms of circular economy (CE). The European Union affirms the need for a comprehensive model of indicators relating to CE in order to meet the needs of all participants (individual companies and industry, society, and the nation), to be based on three perspectives: environmental impact, economic benefit, and resource scarcity. Therefore, the objective of this work is to define these indicators and establish models for measuring the efficiency of processes and products of CE (through Data Envelopment Analysis, (DEA)) in its different manifestations. The models will be useful for both organizations and external users in relation to CE in order to facilitate the search for indicators for all users. Following the bibliographic review of official reports and different high impact works, our results demonstrate the ability to obtain information concerning the main indicators of CE and how the efficiency of CE models has been measured through the most frequently used inputs and outputs.
