Seaports are not only transport nodes but they are also important links in the land-sea transport chains and global
supply chains. Due to the nature of their activities, seaports have a significant impact on both their internal
and external environment. This necessitates the implementation of the concept of Corporate Social Responsibility
(CSR). This concept focuses on, to a large extent, considering the positions of all the stakeholders when
planning and implementing company strategies. Pursuant to the Act on Seaports and Harbours, the seaports in
Szczecin and Świnoujście are ports of primary importance to the national economy. A great challenge for the
ports is to simultaneously balance their development with caring for the environment. The aim of this article is
to determine whether the seaports in Szczecin and Świnoujście are socially responsible and what the result of
their impact on the natural environment and society are. This article uses the case study method, which analyses
the activities undertaken by the port management as well as the enterprises that are part of the port service supply
centres in Szczecin and Świnoujście, and assesses the effects of these activities. From the results, it can be
stated that the Ports Authority, through its business, pro-environmental, pro-social and pro-employee activities,
implements the goals of CSR and is a socially responsible entity, although more could be done.
