Sustainable development has arisen as a result of excessive demands of society, human negligence, and the mismatch of economic growth with its impact on the environment. With sustainable development, we strive to continue economic growth and development, but with the aim of protecting the environment, the proper use of natural resources, and bearing in mind that in this way we care for future generations. This paper combines the main definitions related to sustainable development, scientific facts about environmental problems (climate change, greenhouse effect, excessive consumption of natural resources, etc.) and ways to implement sensitivity for sustainable development in the educational process (specifically in kindergarten, preschool). It faces the complexity of environmental education, ie. the complexity of developing sensitivity to sustainable development in children, and the many aspects it contains: instilling environmental value, creating the preconditions for innovative learning, ensuring a diverse environment, a wealth of materials and incentives on sustainability. Parents, family, educators, peers are responsible for the overall development of the child's sensitivity to sustainable development, ie. the environment in which the child grows up.
