Measuring Environmental Logistics Practices

Current scales do not reflect the multi-dimensional nature of environmental logistics practices (ELPs), and thus cannot adequately measure the entire domain of its practices in the supply chain. In an attempt to fill this gap, the purpose of this study is to develop a valid and reliable scale for measuring ELPs. Based on the relevant literature together with the previous exploratory research, ELPs are proposed as three a priori dimensions: internal environmental management (IEM), environmental sourcing and packaging (ESP), and environmental process design (EPD). With data collected from 129 Korean logistics companies, two measurement models of ELPs were systemically analyzed by using confirmatory factor analysis (CFA). The results show that the validity and reliability of the scale for measuring ELPs are adequately established. Specifically, three basic dimensions (i.e. IEM, ESP, and EPD) are well suited for evaluating ELPs, and the proposed secondorder structure is adequately supported with the systematic and scientific procedures. These indicate that ELPs can be conceptualized as a multidimensional measure comprising IEM, ESP, and EPD.
