This study aims to investigate the impacts of fuel price policies on the concentration of air pollutants in Tehran city. Autoregressive distributed lag (ARDL) estimation models were used to investigate the impacts of gasoline and diesel prices along with the weather and economic variables on the following traffic-related pollutants: carbon monoxide (CO), nitrogen dioxide (NO2), and particular matter 10 micrometers or less (PM10). In the short term, a 1% increase in gasoline prices leads to a 0.02 and 0.012% decrease in the concentration of CO and PM10, respectively. In addition, in the short term, a 1% increase in diesel prices leads to a 0.008, 0.02, and 0.015 % decrease in the concentration of CO, PM10, and NO2, respectively. Results demonstrate that a 1% increase in gasoline prices leads to a 0.011 and 0.02 % increase in NO2 concentration in the short term and long term, respectively. Fuel prices had a greater impact on air pollutant concentration in the long term than in the short term. In the long term, a 1% increase in diesel prices leads to a 0.011, 0.024, and 0.029 % decrease in the concentration of CO, NO2, and PM10, respectively. Although fuel price increases lead to a significant reduction in PM10 and CO concentrations, other factors related to weather conditions (wind speed, temperature, and rainfall) as well as economic activities have a greater impact on air pollution. Therefore, other policies such as improving fuel quality and technology along with other economic policies can be more effective.

燃料价格政策对空气污染的影响:德黑兰案例研究。

本研究旨在调查燃料价格政策对德黑兰市空气污染物浓度的影响。自回归分布滞后 (ARDL) 估计模型用于研究汽油和柴油价格以及天气和经济变量对以下交通相关污染物的影响:一氧化碳 (CO)、二氧化氮 (NO2) 和特殊物质 10微米或更小(PM10)。短期内,汽油价格每上涨 1%,CO 和 PM10 浓度分别下降 0.02% 和 0.012%。此外,在短期内,柴油价格上涨 1% 会导致 CO、PM10 和 NO2 浓度分别下降 0.008、0.02 和 0.015%。结果表明,汽油价格上涨 1% 会导致 0.011 和 0。短期和长期 NO2 浓度分别增加 02%。燃料价格对空气污染物浓度的长期影响大于短期影响。从长期来看,柴油价格上涨 1% 会导致 CO、NO2 和 PM10 浓度分别下降 0.011、0.024 和 0.029%。尽管燃料价格上涨导致 PM10 和 CO 浓度显着降低,但与天气条件(风速、温度和降雨量)以及经济活动相关的其他因素对空气污染的影响更大。因此,提高燃料质量和技术等其他政策以及其他经济政策可能会更有效。燃料价格对空气污染物浓度的长期影响大于短期影响。从长期来看,柴油价格上涨 1% 会导致 CO、NO2 和 PM10 浓度分别下降 0.011、0.024 和 0.029%。尽管燃料价格上涨导致 PM10 和 CO 浓度显着降低,但与天气条件(风速、温度和降雨量)以及经济活动相关的其他因素对空气污染的影响更大。因此,提高燃料质量和技术等其他政策以及其他经济政策可能会更有效。燃料价格对空气污染物浓度的长期影响大于短期影响。从长期来看,柴油价格上涨 1% 会导致 CO、NO2 和 PM10 浓度分别下降 0.011、0.024 和 0.029%。尽管燃料价格上涨导致 PM10 和 CO 浓度显着降低,但与天气条件(风速、温度和降雨量)以及经济活动相关的其他因素对空气污染的影响更大。因此,提高燃料质量和技术等其他政策以及其他经济政策可能会更有效。尽管燃料价格上涨导致 PM10 和 CO 浓度显着降低,但与天气条件(风速、温度和降雨量)以及经济活动相关的其他因素对空气污染的影响更大。因此,提高燃料质量和技术等其他政策以及其他经济政策可能会更有效。尽管燃料价格上涨导致 PM10 和 CO 浓度显着降低,但与天气条件(风速、温度和降雨量)以及经济活动相关的其他因素对空气污染的影响更大。因此,提高燃料质量和技术等其他政策以及其他经济政策可能会更有效。
