Sustainability of transport systems is a key issue in transport. The main question is whether high levels of road and railway transport in areas along navigable waterways is an effective solution for this issue. The Danube waterway is an example. Generally, it is not observed that traffic performance is not as high as on the Rhine. This paper deals with the revelation of the available capacity of this waterway based on approximation functions and their comparison with real transport performances. This methodology points to the level of use of waterways. The connection of this model with the production of fossil fuels creates a basis for a case study. The case study in this paper offers a possibility for a sustainable and environmentally friendly transition from road transport to inland water transport on the example of specific transport routes. The main contribution of this paper is a presentation of the application of sustainable models of use transport capacity to increase the share of environmentally friendly and sustainable inland water transport. The conclusion based on the case study and materials is that the available capacity of inland water transport on the Danube could support the transition of traffic performances to sustainable and environmentally friendly means of transport.

Mai világunkban egyre több olyan erőforrást élünk fel, amelyek hatását az otthonunknak számító Föld egyszerűen már nem képes helyreállítani. Ebben számos jelenség mellett a gazdaság globalizációja, az élesedő versenyhelyzet, a fogyasztói társadalom további térnyerése, ebből adódóan pedig a logisztikai folyamatok intenzitásának növekedése kulcsszerepet játszik. A logisztikát érő kritikáknak ösztönözniük kell a vállalatok szakembereit arra, hogy változtassanak ezen. Ehhez elengedhetetlen a jelenlegi működés szénlábnyomának mérése. Csak a jelenállapot felmérése szolgálhat alapjául a fejlesztéseknek. A szerzők tanulmányának célja a szénlábnyomszámítás egy gyakorlati alkalmazásának ismertetése. Esettanulmány jelleggel bemutatják egy nagy nemzetközi vállalat hazai leányvállalatának a szénlábnyom-számítása során alkalmazott módszertanát. A számítások során a vállalat disztribúciós logisztikai folyamataira fókuszálnak, kiemelten vizsgálták a közúti szállítás és a raktározás széndioxid-kibocsátását. Számításaikban igyekeztek pontosak lenni, a hazai energiamixre számolt legfrissebb konverziós faktorokkal számoltak. Meggyőződésük, hogy az ilyen esettanulmányok hasznosak, hiszen a bemutatott módszertan mintául, útmutatásul szolgálhat további vállalatok számára. Reményeik szerint ezzel segíthetik, hogy minél több hazai vállalat kezdje el széndioxid-kibocsátásának szisztematikus és tudományos alapokon nyugvó mérését. ____ Due to globalization, intense competition and the consumer society logistics processes have been intensified during the last decades. This led to increased environmental strain generating intense criticism towards logistics profession. In order to decrease the environmental burden of logistics several professionals and companies have tried to make progress in this field and introduced techniques that are capable to measure the Carbon Footprint of logistics. Still public case studies are very limited. The paper presents the case of the Hungarian subsidiary of a big multinational FMCG firm. Calculations are built on the actual conversion factor developed for the Hungarian energy mix. A complex set of key performance indi actors usable to capture key characteristics of the present situation is presented. Not only the constructs of these KPIs are described in the paper but a detailed description of methodology used to calculate them is also given. The authors hope such detailed case study description will help other companies as well to initiate sustainable logistics programs.

Despite the political objective of decreasing road transport and transfer cargo to road and sea, short sea shipping is struggling. There is therefore a need for development of new short sea Ro-Ro vessels which use significantly less fuel per ton transported which can be built at a modest cost. This feasibility study has: First mapped the main characteristics of the current fleet, i.e. dimensions, capacities, installed power and designs speeds; Second investigated alternative combinations of main measurements to enable more slender hull forms which require less power and hence give fuel consumption and fuel cost per transported unit; Third, performed a case study to compare the economic and environmental performance of these slenderer designs, with traditional designs and road only solutions. This study shows the advantage of investigating a large number of alternative dimensions and capacities to identify the designs which reduces cost and fuel consumption. And that the best option is to design and build more slender vessels.
