Abstract

number of different methods and programs are used to calculate greenhouse gas emissions (expressed in kg CO₂e) resulting from transport, either as a total quantity or as emissions per kilometer traveled or per product kilometer (e.g. ton-kilometer). In many cases, total emissions can be estimated reasonably well, but the figure calculated has no operational meaning, i.e. it cannot be used to identify potential improvements or monitor operational performance. In 2014 a methodology was developed within the framework of the Lean & Green program to analyze data and relate the outcome to (potential benefits for) operational performance. Moreover, the market can use Lean & Green Analytics to provide their customers with good and comparable emissions data (which cannot be ‘misused’ as a justification for demanding lower prices). In the course of two years, the data sets made available were used to test whether the methodology works in the participating companies’ everyday practice. Empirical research regarding the usability and effects of Lean & Green Analytics stimulates standardization in greenhouse gas emissions calculation and provides companies with a practicable tool. This paper presents the initial results of that research.
