Evaluating CO 2 emissions and fatalities tradeoffs in truck transport

Evaluating CO 2 emissions and fatalities tradeoffs in truck transport Purpose – The purpose of this paper is to model the tradeoffs among fatalities, CO 2 emissions and value generated by the truck transportation portion of supply chains with the goal of determining if efforts to reduce CO 2 emissions increase transportation‐related fatalities. Design/methodology/approach – The joint production of CO 2 , fatalities, and truck transport value in the 50 US states during 2002‐2007 is modeled using data envelopment analysis. The directional output distance function is estimated under two assumptions: strong and weak disposability of CO 2 emissions. This provides the means of calculating shadow prices that estimate the cost of reducing CO 2 emissions. Findings – The authors' findings indicate that the transfer of resources to the reduction of CO 2 emissions will result in a statistically significant increase in fatalities and a statistically significant decrease in value of transport from truck transport. Research limitations/implications – The model presented is based on secondary data from the Federal Highway Statistics Series, the Fatality Analysis Reporting System, and the Bureau of Economic Analysis. Social implications – The model developed demonstrates tradeoffs among sustainability‐related variables. Originality/value – The model presented in the paper uses shadow prices to assess sustainability‐related tradeoffs in supply chains. While this method has been used in other fields, this is its first use in supply chain studies. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png International Journal of Physical Distribution & Logistics Management Emerald Publishing

Abstract

Purpose – The purpose of this paper is to model the tradeoffs among fatalities, CO 2 emissions and value generated by the truck transportation portion of supply chains with the goal of determining if efforts to reduce CO 2 emissions increase transportation‐related fatalities. Design/methodology/approach – The joint production of CO 2 , fatalities, and truck transport value in the 50 US states during 2002‐2007 is modeled using data envelopment analysis. The directional output distance function is estimated under two assumptions: strong and weak disposability of CO 2 emissions. This provides the means of calculating shadow prices that estimate the cost of reducing CO 2 emissions. Findings – The authors' findings indicate that the transfer of resources to the reduction of CO 2 emissions will result in a statistically significant increase in fatalities and a statistically significant decrease in value of transport from truck transport. Research limitations/implications – The model presented is based on secondary data from the Federal Highway Statistics Series, the Fatality Analysis Reporting System, and the Bureau of Economic Analysis. Social implications – The model developed demonstrates tradeoffs among sustainability‐related variables. Originality/value – The model presented in the paper uses shadow prices to assess sustainability‐related tradeoffs in supply chains. While this method has been used in other fields, this is its first use in supply chain studies.
