In this paper, we will talk in more detail about ecology and green logistics, their divisions and applications in everyday life with the aim of improving the living conditions of all living organisms on Earth. Climate change, soil, water and air pollution and noise represent the biggest challenges of ecology. Solving these problems is possible by applying more environmentally friendly strategies, introducing regulations and laws for pollution regulation and gradually informing and educating people. In terms of green logistics, its subsystems will be discussed and supported by an example of a company for easier understanding. The goal of green logistics is to find a balance between economy and ecology, so that both sides are satisfied. In addition to green logistics and ecology, an important role is also represented by sustainable logistics, which finds a balance between ecological, economic and social aspects. By applying the goals of the 2030 Agenda, it greatly facilitates the implementation of sustainable logistics through 17 goals.
