Sustainable logistics is an increasingly important discipline and is not just an option but becomes imperative if the company wants to remain competitive. The paper investigates the application of the principles of sustainable development in logistics and the social aspect of sustainable logistics. The theoretical framework of the concept of sustainable development is presented, the social aspect of sustainability is described in more detail, and sustainability in logistics, i.e. the concept and elements of sustainable logistics, is analyzed. Social sustainability was analyzed on the example of the DHL company. This company is an example of the successful implementation of the principles of sustainability in business, which refers not only to the application of the principles of sustainable development, but also to innovation and the creation of an entire portfolio of education services and technical and logistical support for other companies in their green transition. Although doing business according to the principles of sustainability for companies often means higher investments in the beginning, in the long term it brings resource savings, in addition to the significant benefits that a sustainable way of doing business has for the whole community.
