The United Nations Sustainable Development Goals are grouped under three main titles; economic development, environmental sustainability, and improvement of social well-being. Environmental sustainability is one of the most important components of sustainable development goals because it is obvious that without a sustainable environment, economic and social development goals will be abandoned. While the unplanned use of the environment and natural resources threatens environmental sustainability, it can be said that one of the most important actors in this process is sports. Mass production and consumption, facility establishment, and increase in organizations in sports accelerate environmental and natural destruction. The sustainability of sports is directly proportional to environmental sustainability. Therefore, reduction of the sports-induced negative environmental impacts will make great contributions to environmental sustainability. In this way, it will be possible to transfer both the natural environment and sports to future generations. This study was limited to environmental sustainability, which is one of the three main titles set for sustainable development goals and the effects of sports on environmental sustainability were evaluated in the light of available literature. Again, regarding the existing literature, suggestions were developed to reduce the negative environmental impacts of sports.
