Aside from the obvious benefits of logistics for the economy, the social and ecological costs cannot be denied. Scarcity of land, increasing traffic congestion in the region and increased emissions of harmful gasses are a few examples of this. This means that a new challenge presents itself: sustainable logistics. Sustainability is generally defined as meeting present needs without mortgaging the needs of future generations.
Until now, companies had the goal of optimising their supply chains to be more efficient and more effective, without very much consideration of sustainability. Maximum efficiency in this is usually expressed in a minimal total logistical cost, or total supply chain cost. Effectiveness generally refers to the service level that is offered to the client, often expressed in terms of delivery frequency, delivery quantities, delivery times, etc. Performant supply chain management makes it possible to improve efficiency and effectiveness together, to a certain level. Beyond that level the company has to choose for efficiency or effectiveness, depending on its strategy.
More and more companies are starting to demand sustainable logistics. This means that the existing trade-off between effectiveness and efficiency must now be expanded to include sustainability as well. The result is that the space to optimize the three criteria at once becomes very tight. It is hard to imagine that a company can minimise its supply chain costs by making all its transport comodal, and simultaneously making more frequent deliveries in smaller quantities. Yet the opportunities are there: collaboration, consolidation, in other words bundling streams is the key word. Companies that are prepared to bundle their streams horizontally will succeed in improving all three of their supply chain demands at once.
To be able to offer the logistics sector as many opportunities as possible to develop towards sustainability without significantly increasing social impacts, the Flemish Logistics Institute has developed the “Extended Gateway® Flanders” concept. First of all, the Extended Gateway® Flanders concept responds to a trend that has already been apparent for some time. Sea and air ports are taking initiatives in the area they serve to increase their competitiveness. Hence the term Extended Gateway® Flanders.
