Air pollution in big cities, including Depok City, is becoming an increasingly pressing environmental issue, with one of the main contributors being carbon dioxide (CO₂) emissions from motor vehicles. One of the factors influencing the increase in CO₂ emissions is unorganized parking management, which causes congestion and increased vehicle travel time. This study aims to analyze the implementation of parking regulations in Depok City and its impact on the level of CO₂ gas pollution produced by motor vehicles. The study was conducted using a quantitative method, through direct measurement of CO₂ gas concentrations at several crowded parking spots in urban areas, and analyzing the effectiveness of the implementation of existing parking regulations with applicable government regulations, especially those related to controlling motor vehicle emissions. The results of the study showed that locations with poor parking management had much higher CO₂ gas concentrations, with an average value reaching 350 ppm (parts per million), while locations with good parking management were recorded at 220 ppm. This increase in emissions was caused by longer travel times due to congestion caused by unorganized parking. In addition, although there is PP No. 22 of 2021, the implementation of parking regulations in Depok City is still not optimal, so that supervision of vehicle emissions and parking arrangements need to be improved. This study suggests the need for more structured parking management and strict supervision of motorized vehicles operating in Depok City. Thus, it is expected to reduce congestion, reduce CO₂ emission levels, and improve air quality in Depok City, in line with the government's goals in controlling air pollution.
