South Bronx environmentalists say congestion pricing is worsening local air quality
An environmental advocacy group in the Bronx says congestion pricing is contributing to declining air quality in parts of the borough.
South Bronx Unite partnered with researchers at Columbia University to analyze air quality data before and after the tolling program began in January 2025.
The group used 19 air quality monitors in key locations throughout the borough that are near highways, bridges, and schools. Those air monitors record particulate matter in the air every hour, and did so before congestion pricing went into effect too. They found the majority of the monitors did show an increase in particulate matter. Only two monitors showed decreases, and those are located near green spaces.
One monitor located between the Major Deegan and Bruckner expressways saw the highest spike. Advocates with South Bronx Unite say some drivers may be rerouting through the Bronx to avoid congestion pricing fees, which can lead to an air quality decline.
Sources with the MTA say there is no direct evidence linking those traffic patterns to the tolling program, but adds that $70 million from congestion pricing is being invested into environmental improvements in the Bronx.
South Bronx Unite says they want to be a part of the conversation with MTA when it comes to strategies to improve the air quality in the borough.
