Coordinated freight logistics in existing city districts- Evaluation of methods for calculating energy and environmental effects
Norra Djurgårdsstaden is the largest ongoing construction project in Sweden and is planned to be completed in 2030. The city district is situated in north-eastern Stockholm, in a former industrial area where approximately 12 000 new homes and 35 000 workplaces are planned. The city district focuses strongly on reducing energy consumption and the negative impacts on the environment. One idea for realizing this goal is to implement coordinated freight logistics. This can be accomplished by building a consolidation centre where goods from different logistics companies and freight carriers can be loaded together on the same delivery vehicles and then be delivered in the same area in Norra Djurgårdsstaden.
The purpose of this master thesis is to evaluate five earlier evaluation reports on consolidation centres. Based on these evaluation reports and other relevant literature, it is recommended how a coordinated freight logistic project should be organized in Norra Djurgårdsstaden and how the impact on the environment and energy consumption should be calculated. The evaluation reports are from the logistic centre in the Old Town of Stockholm, the pilot project Samlic in Linköping, the urban consolidation centre in Norwich, the micro-consolidation centre in London and several urban logistic practices in Utrecht. A thorough comparative analysis of the five different evaluation reports has looked at the initiators and the stakeholders, the delivery situation before and after the implementation of the consolidation centre as well as done a deeper evaluation analysis of all the evaluation reports. The comparative analysis showed that the consolidation centres have had a positive effect on decreasing the number of delivery vehicles in the city district and thereby reducing the emissions and the energy consumption from the delivery vehicles.
Based on the comparative analysis and other literature it is suggested that the initiative to build a consolidation centre in Norra Djurgårdsstaden has to come from the City of Stockholm. The stakeholders should be the City of Stockholm, logistics companies, freight companies, the different businesses in the area and the Ports of Stockholm. To encourage even more businesses to have deliveries from the consolidation centre and get more environmentally friendly delivery vehicles in the city district it might be necessary to use several management control instruments. Examples of control instruments are environmental zones, time windows and implement different restrictions on the delivery vehicles. It is essential to gather information about the delivery vehicles in the city district to estimate emissions and the energy consumption. The collection of data from the delivery vehicles can be gathered from consignment notes, driver notes, invoice data or statistics of the number of vehicles that have delivered goods in the city centre from freight and logistics companies. Then the delivery vehicles impact on energy consumption and the environment can be estimated with the computer tool Network of transports and environment (NTM-method).
