The objective of our research was to analyse the relevant logistic factors
influencing energy efficiency in road freight transport, while quantifying the
potential for CO2 reduction. We carried out a survey and linked fuel
consumption to transport performance parameters in 50 German haulage
companies during 2003. Efficiency ranges from 0.8 tkm to 26 tkm for 1 kg CO2
emissions. The results show a high potential for improvements, given a low level of efficiency in vehicle usage and load factor, scarce use of lightweight vehicle design, incorrectly selected vehicle class and a high proportion of empty runs.
Efficiency measures are poorly applied.
