This paper computes and analyses for the first time environmental efficiencies in waste generation of 160 European regions in NUTS 2 level in seven European countries. For this reason different Data Envelopment Analysis (DEA) model formulations are used modeling the pollutant in the form of...

This study analyzes environmental efficiency, and its determinants, for 98 countries in terms of four typical air pollutants—SO2, NOx, particulate matter 10 micrometers or less in diameter (PM10), and CO2—for the period 1970–2008. For this purpose, I propose a super slacks-based measure...

China’s unbundling reform in 2002 aimed to introduce competitiveness into the power industry, especially the generation sector, to improve its operational efficiency. Meanwhile, great concern about a range of environmental problems and global climate change increasingly calls for saving energy...

This study analyzes the impact of international trade on environmental efficiency. Using a data envelopment analysis (DEA) model that allows us to treat undesirable outputs and super-efficiency beyond unity, we measure the environmental efficiency of four typical air pollutants-SO 2 , NOx,...

A metafrontier slack-based efficiency measure is presented to measure environmental efficiency for various regions in China. The objective of the new approach is to investigate the change of environmental efficiency while incorporating group heterogeneities and all variable slack and...

Gangtok, the capital of Sikkim is one of the largest town in the state, located in the eastern Himalayan Region of the Indian state of Sikkim. Present paper aims to portray and enlighten the current waste management and practices in Gangtok. Reviews, the lately planned solid waste management...

By applying conditional and unconditional data envelopment analysis (DEA) models along side with statistical inference using bootstrap techniques; this paper investigates the link between China’s carbon dioxide emissions (CO2) environmental efficiency and its economic growth (measured in GNI...
