The globalizing world is faced with many environmental problems, and the reports prepared show that environmental problems are becoming more serious day by day. Some of the studies focused on reducing environmental problems focus on the concept of ecological footprint awareness. There are many studies showing that environmental behaviors are acquired at an early age. In this context, it is important to conduct research on ecological footprint awareness in early childhood. This research was designed in a mixed design, the quantitative part was conducted in a semi-experimental design and the qualitative part was conducted in a basic qualitative research design. 15 experimental and 15 control group children aged 5-6 were studied. As a result of the research, it was seen that the environmental knowledge and awareness of children and their parents was limited, and it was determined that the education program developed in line with the data received from the participants was effective on the ecological footprint awareness of their children.
