Circular economy (CE) aims at sustainable development (SD) by focusing more on renewable sources of energy and precise management of waste to i) guarantee the secure access to resources, ii) combat climate change and global warming. Environmental issues arising from energy use and lack of policies to monitor them challenge sustainable development. Circular economy emphasizes the economic development with the least amount of undesirable environmental impacts. To evaluate the environmental performance of decision-making units (DMUs) with data envelopment analysis (DEA), this paper develops a common set of weights (CSW) model using the ideal point method. Therefore, energy and environmental efficiency of the organization for economic cooperation and development (OECD) countries is analyzed using the Malmquist productivity index (MPI) during 2012-2015. Although Switzerland has the highest energy and environmental efficiency during 2012-2014, findings indicate that Ireland and the USA have continuously improved their energy and environmental efficiency.
循环经济（CE）通过更加关注可再生能源和废物的精确管理，旨在实现可持续发展（SD），以保障资源的安全获取、应对气候变化和全球变暖。能源使用和缺乏政策来监测这些能源使用带来的环境问题，对可持续发展构成了挑战。循环经济强调在对环境影响最小的情况下实现经济发展。为了使用数据包络分析（DEA）评估决策单元（DMU）的环境绩效，本文使用理想点法开发了一套通用权重（CSW）模型。因此，在 2012-2015 年期间，使用 Malmquist 生产力指数（MPI）分析了经济合作与发展组织（OECD）国家的能源和环境效率。尽管瑞士在 2012-2014 年期间拥有最高的能源和环境效率，但研究结果表明，爱尔兰和美国一直在提高其能源和环境效率。
