The implementation of construction projects largely determines the development of modern cities. However, such projects impact both urban freight transport and residents. To reduce this impact, increasingly more
attention has been paid to the issues of sustainable development. Sustainable urban freight transport has become a priority for European cities. It also contributes to construction supplies. This article presents the results
of analyzing construction supplies and the assessment of their compliance with the principles of sustainable
development using the example of the city of Szczecin. This allows for the diagnosis of problems in this area,
and solutions in the field of sustainable construction are collected. The presented research includes unstructured
observation of construction projects in progress, structured interviews with entities implementing construction
projects in Szczecin, and additional expert research to identify solutions in the field of sustainable construction
supply in cities. This enables the research objective to be achieved and conclusions to be developed.
