New York City's $9 Congestion Toll Falls Short on Air Quality Gains

NYC’s year-old $9 congestion toll in Manhattan reduced vehicle traffic by about 11% but did not produce a statistically significant improvement in overall air quality, because cars contribute only around 10% of the city’s emissions and other sources (heating, power plants, restaurants) dominate. Officials tout reduced congestion, quieter streets, and transit funding as benefits, while critics say the toll is an expensive burden with limited environmental payoff.
