Urbanization has increased rapidly in the world. It uses an intensive resource consumption for urbanization and the expanding economy. The consequences of unconscious consumption of these resources, which constitute the thermodynamic system of cities, are solid wastes, wastewater and air pollution. As a result of improper management of these wastes in cities, it increases the effect of climate change by producing greenhouse gas emissions directly or indirectly. The most innovative approach in controlling these effects is “low-carbon city” studies. Turkey should give priority to low-carbon city applications that comply with the European Green Deal and transition to a green economy. In this context, with this study, applications and solutions were examined together to become a low-carbon city in Turkey. Considering policies and commitments, the roadmap is drawn in this way, the study will be a reference for many cities.
