An increasing consciousness on climate change problems has recently induced countries to apply environmental regulations, either on voluntary or compulsory basis, in order to curb greenhouse gas emissions generated by human activities. The European Emission Trading Scheme (EU-ETS) is the widest cap and trade system in the world. As other environmental systems, the EU-ETS aims at monitoring CO2 emissions from specific industrial sectors and cement is one of them. In this paper, we analyze the environmental performance of cement industry operating in 21 worldwide countries taking into consideration both the desirable (cement) and the undesirable (CO2 emissions) outputs of its production process. Three DEA models with undesirable outputs and a directional distance function approach are compared in order to measure the environmental performance of cement industry under different points of view. The analysis, carried out for the years 2005-2008, points out the changes in efficiency levels within these years and the effects of emission regulations on the global performance of cement industry.

Abstract
An increasing consciousness on climate change problems has recently induced countries to apply environmental regulations, either on voluntary or compulsory basis, in order to curb greenhouse gas emissions generated by human activities. The European Emission Trading Scheme (EU-ETS) is the widest cap and trade system in the world. As other environmental systems, the EU-ETS aims at monitoring CO2 emissions from specific industrial sectors and cement is one of them. In this paper, we analyze the environmental performance of cement industry operating in 21 worldwide countries taking into consideration both the desirable (cement) and the undesirable (CO2 emissions) outputs of its production process. Three DEA models with undesirable outputs and a directional distance function approach are compared in order to measure the environmental performance of cement industry under different points of view. The analysis, carried out for the years 2005-2008, points out the changes in efficiency levels within these years and the effects of emission regulations on the global performance of cement industry.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
