Urban leaders in areas with high air pollution often face the dual task of reducing pollution levels while educating the public about the health impacts of pollution and preventive measures. Transportation policies to cut motorized personal vehicle use are often a key part of pollution reduction efforts. One type of these policies is information interventions educating commuters of the higher emissions impact of cars. This study evaluates the impact of such an information intervention on car commuters’ intention to switch from car use to transit, biking, or walking in Zhengzhou, China. Further, it tracks how this greening impact evolves as drivers are given additional public health information regarding Zhengzhou’s severe air pollution level, its health effects, and the reduced pollution exposure when driving compared with transiting, biking, or walking outside in polluted air.
