This report presents the results of a study to define a standardized approach to measuring the carbon footprint of the transportation component of supply chains, evaluate existing methodologies, and prepare a work plan for a decision tool to measure the carbon footprint. Existing methodologies were reviewed and used to create a standard definition of the carbon footprint of the transportation component of the supply chain. The proposed definition focuses on direct transportation activities, considers the six primary greenhouse gases, and uses a well-to-wheel emissions scope. A list of criteria to evaluate current methodologies were developed based on concepts from accounting, supply chain management, and life cycle assessment. The criteria of breadth, depth, and precision define how relevant a measure is to decision-making, while the criteria of comparability and verifiability assess its suitability for external reporting. Using the Analytic Hierarchy Process, the criteria were used to evaluate existing programs and methodologies. Participants in a workshop identified the relative importance of each criterion, and these weightings were used to evaluate the methodologies. The results of this exercise were used to identify strengths and weaknesses of current approaches, and inform the design of the decision tool.
