In the German Action Programme effizient mobil the possible CO2-reduction for Mobility Management in 85 companies has been estimated based on different surveys. The total CO2-reduction of the 85 companies, which participated, is about 23600t/a.
The Action Programme effizient mobil of the German Energy Agency is funded by the Federal Ministry for the Environment. It aims for a further dissemination of Mobility Management. The programme supports the uptake and the effective implementation of Mobility Management, both within the municipalities and for different sites and organisations. In the first phase of the programme 15 regional networks were established to address municipalities and companies and to involve different regional actors. More than 100 municipalities and companies got free of charge initial consulting that led to a specific concept taking the framework conditions into account.
The ISB-Institute for Urban and Transport Planning and the ILS-Research Institutes for Regional and Urban Development are assigned with the evaluation of processes (mainly ILS) and the estimation of effects (mainly ISB). This paper concentrates on the results of the estimation of effects.
Mobility management measures have effects on different target fields. With the aim to promote the environment friendly transport modes and an efficient use of the existing transport systems mobility management has an important effect on the environment. By shifting trips from cars to environment friendly transport modes noise exposure, pollutant emission, land consumption and separating effects on people´s living space can be reduced. Another target field of mobility management is health. The modal shift from car use to non-motorized transport leads to more exercise and therefore to a better health. The safety of transport can be described by the number of accidents due to transport modes. As each mode has a different accident rate modal shift has an impact on safety. In addition mobility management has an influence on costs. On the one hand the measures can lead to decrease mobility costs of people, if trips are shifted from car to environment friendly transport modes. On the other hand companies or authorities need to carry the costs of the measures. Within the framework of the project the focus is on the estimation of CO2 reduction in order to point out the positive outcome of mobility management on the climate.
The assessment of possible CO2-reduction took into account the reduction of staff car mileage to and from workplaces. The potential savings were estimated by using the planned Mobility Management measures, the data on site conditions and the mobility behaviour of the staffs. In regards to the newly developed method for estimating the possible CO2 reduction of MM one must take into account that this type of assessment is quite complex. Mobility Management comprises a variety of measures with also different effects and effectiveness in regards to CO2-reduction. They are also often implemented within different bunches of other measures showing only a combined effect. And there are hardly any evaluation data available which shows real effects. Therefore a two-step approach was developed. In regards to the possible effect the approach takes many factors into account. In the first step it calculates a theoretical potential of CO2-reduction based on more objective factors. The second step looks at the more realistic potential due to the share that can be achieved in relation to the planned measures.
The analysis is based on data from 85 companies. It shows that with 64% of all locations a major proportion is well accessible by public transport. The classification of location for non-motorized transport is in the upper and medium range. At many locations there is already a high restriction of motorized private transport (47% of the locations). At 18% of the locations though is only little or no restriction however no classification could be made for 14% of the locations due to a lack of information.
By extrapolating the data obtained in the staff surveys conducted as part of the consultation sessions it can be seen that there are, in the companies surveyed, in all some 53000 people driving to work by car. Some 28% of these cannot use other forms (public transport/ car pools) due to their individual circumstances. However, 72% could, at least in theory, shift to other means of transport. To what extent this potential is tapped is dependent on the proposed measures and on the local quality of the alternative means of transport. An analysis of 85 concepts showed that on average 26% of the theoretical potential is being tapped. A full implementation of all concepts of the participating companies would lead to an average CO2-reduction of 0.19t/a for each employee and an average reduction of 248t/a for each company. The total CO2 reduction of the participating companies is about 23600t/a.
