1 Climate mitigation through efficiency in the road freight transport sector: vehicle approach and policy recommendations Jacques Leonardi Pedro J. Pérez-Martínez Transport Studies Group Christophe Rizet Dept. for Transport Economy and SociologyRoger W. Worth

2 Introduction and background Many open scientific questions and a wide debate on freight transport, energy and climate Domestic actions tackling climate change Dualities that would have to be linked: –Organisation and technology solutions –Impacts and measures –Survey methods and vehicles data –Company approach and policy approach –Decisions and limitations

3 Scientific questions How people behave with existing solutions? What are the main barriers for an implementation of mitigation strategies? What could we suggest to overcome them? A holistic approach is impossible  Define a feasible, pragmatic approach

4 Objectives of the vehicle approach to observe, quantify and understand energy consumption parameters and changes at a disaggregate vehicle level to understand how a behavioural change is leading to a net decrease in final energy use or CO 2 -emissions of the vehicle to understand how this change can be (potentially) supported by vehicle related measures taken by decision-makers in companies and in the public sector

5 Definition The vehicle approach is: Field oriented, but it needs modelisation to start Applying and defining survey methods Looking to impacts on transport & energy parameters Using interviews, data collection and statistics analysis

8 A comparative analysis: France, UK, Spain and Germany Main selection criteria for the choice of the comparisons presented is the data quality, notably the possibility to relate fuel use, tonne-km and vehicle type correctly in one sample Use of two types of data sources : –National statistics –Targeted surveys

15 Why these differences and similarities? Different transport patterns in the four countries? Different samples? Different survey methods?

19 Limitations Several limitations are hampering the quality of the comparative study The surveys were not designed for the purpose of this study, but were aiming at establishing other scientific results and reports in some cases, the efficiency indicator was build on original primary data from surveys, in other cases, on secondary, calculated data from at least two different sources

20 ‘everything else remains stable’ One central condition for scientific comparison is that ”..” excepting the differences in the objects of the analysis. This situation is not given, since business conditions and countries economies are changing from year to year. Therefore many external factors, not related to vehicles, and not mentioned in the explanations, could have been influencing the results: –Influence of cabotage, –logistics decision making and –other non technological factors discussed in McKinnon (2003)

Is this a no policy area because investments are ‘for free’ ?

22 Conclusion Surprising similarities in the aggregated efficiency indicators Use of Key Performance Indicators in National or targeted surveys are the dominating methodologies in the studies presented Data from National Statistics are widely used Potential critical points are: –How to best evaluate the impacts of the measures at the company level and avoiding pitfalls? –How to ensure that positive effects on efficiency can be repeated in other companies? –How to support companies through public policy?
