Background and Objective: The intensification of urban air pollution as a result of traffic growth has led to an increase in pollutants such as particulate matter and nitrogen oxides. Therefore, policy-making in the field of urban transportation has become one of the main axes for controlling and reducing air pollutants. The aim of the present study is to review and analyze the policies and tools used to reduce air pollutants resulting from fuel consumption in urban transportation.
Materials and Methods: Original research articles were selected from reputable databases. In total, 20 articles from studies published between 2015 and 2025 were retrieved, primarily from databases such as Scopus, Google Scholar, Web of Science, and ScienceDirect.
Results: Economic policies, such as fuel price reform and congestion pricing, have primarily operated by reducing travel demand and fuel consumption, and in many cases have been associated with short-term reductions in traffic pollutants. Regulatory and enforcement policies, such as technical inspections and traffic restrictions, demonstrate higher effectiveness when monitoring and law enforcement are conducted continuously and strictly. Technological and fleet policies, such as electrification and fleet modernization, have the potential for more sustainable reduction of combustion pollutants, but their success depends on infrastructure readiness and the speed of fleet replacement. Behavioral and managerial policies, including promoting cycling and travel demand management, can achieve pollutant reduction through decreased traffic volume, provided they create a significant shift in travel duration.
Conclusion: The results of this study indicate that none of the policies are sufficient on their own, and success in reducing air pollution requires a combined policy package. Strengthening implementation prerequisites, such as continuous monitoring, strict law enforcement, and the development of necessary infrastructure, is a key and fundamental condition for the success of policies aimed at reducing air pollutants in cities. Policymakers must employ a combination of economic, regulatory, and technological tools, taking into account the local conditions of each city, to achieve environmental sustainability and reduce urban air pollution.
