Sport has an exceptional importance in society and culture. In addition to social, health, economic and other sports, a contribution can also be made in the fight against climate change in parts related to the sustainable consumption of non-renewable resources. The aim of this work was to examine the environmental sustainability of football sports facilities in the Republic of Croatia through a questionnaire that was sent to 25 football clubs playing in the first, second or third Croatian football league. The survey questionnaire contained 25 questions relate to the size of the stadium, the age of the facility and renovation. The second part related questions about the maintenance of the grass surfaces of the main and auxiliary playgrounds, as well as water consumption, the method of using fertilizers and electricity. The results of the survey revealed that football stadiums are large consumers of water and electricity. In the future, it will be necessary to invest significantly more in information, knowledge and education so that those who take care of the sports infrastructure become familiar with all the possibilities of improving the sports infrastructure, which must be more energy efficient and environmentally friendly.
