NYC Congestion Pricing Reduces Air Pollution by 22% in Six Months

New York City's congestion pricing scheme, implemented in January 2025, has led to a 22% reduction in air pollution within the toll zone over its first six months. The program, which charges cars $9 to enter busy areas of Manhattan during peak hours, has also resulted in decreased traffic and improved air quality across the metropolitan region, as reported by a Cornell University study analyzing data from 42 air quality monitors.
