consolidation of indicators

Range and individualisation of diversified logistic services vary substantially. A unique indicator for specific CO2-emission is not a viable option. The author proposes to aggregate individual CO2-efficiency trends of sub-entities by adding all singular tendencies during a reporting period weighted against the overall CO2-emission of the reporting entity or group of entities. The result is a weighted average tendency giving a viable indication of the specific CO2-emission trends of a logistics service provider.
