Supply chains in an urban tourist destinations are for many people barely noticable or are not aware of them at all. Behind supply chain management there is large network of processes that participate in supplying the destination with all the neccesary goods and materials needed for its smooth operations. From everyday products that population needs for life and for needs of all branches in the economy. In order for the supply chain to function smoothly, behind that name there are a number of processes and a large number of people who participate in these same processes. When we talk about the sustainability of these same supply chains, a number of changes need to be made in the current management. The supply chain does not need to be viewed from the side of sustainability only in terms of environmental protection, but also the simplification of processes, the functionality of each of the processes and each work within the chain, as well as the quality of life of the local population. This paper investigates freight traffic in the City of Zagreb, with the greatest emphasis on road traffic, which in terms of each transport system has the greatest impact on nature. The city of Zagreb is an urban tourist destination and despite the fact that most people may not notice the freight traffic in the city of Zagreb, it has strong influences on the tourism sector and the view of domestic and foreign tourists towards the destination. In terms of tourism and movement of visitors within the destination, traffic generally has great impact, because the movement of trucks burden roads and prevent visitor mobility, trucks have an impact on the environment but also on historic buildings, which certainly does not contribute to the destination in tourism and that is why sustainable supply chain management is important. As the largest city in the Republic of Croatia with its surroundings of over one million inhabitants, the transport system can be seen as "clogged" of the transport system, so Zagreb must soon turn to improving the current traffic situation, reducing adverse impacts and overall sustainability in all aspects of the supply chain.
