New York City congestion toll shows no significant air quality improvement

A report from the New York City Health Department indicates that the $9 congestion toll implemented in Manhattan’s Congestion Relief Zone has resulted in no statistically significant improvement in overall air quality after its first year.

While the toll led to an 11% reduction in traffic, researchers noted that vehicles only account for approximately 10% of the city’s total pollution. The report highlights that New York City’s air quality is primarily impacted by other sources, such as emissions from buildings used for heating and hot water, restaurants, and power plants.

Despite the lack of pollution reduction, city officials pointed to other benefits of the January 2025 implementation, including improved public transit, reduced traffic noise, and decreased congestion levels.
