New York City congestion pricing shows stable air quality in first year study

A first-of-its-kind study by the New York City Health Department has evaluated the environmental impact of the city’s congestion pricing program during its first year of implementation. The report indicates that air quality across New York City remained stable or showed slight improvements, continuing a long-term 20-year trend of declining pollution.

Researchers specifically addressed concerns that drivers might circumvent the Manhattan tolling zone, potentially increasing pollution in surrounding areas like the South Bronx or Staten Island. The study found that these neighborhoods did not experience increased levels of air pollution attributable to the program.

Since its introduction in early 2025, the program has charged drivers up to $9 to enter Manhattan below 60th Street during peak hours. Officials noted that the initiative has led to fewer vehicles in the central business district, increased transit ridership, and generated significant revenue for public transportation and air quality initiatives.
