A first look at the effects of Congestion Pricing on air quality

The congestion-pricing program that charges drivers who enter Manhattan below 60th street had sparked concerns among some communities who worried that it could incentivize drivers to go through other, already congested parts of the city, exacerbating air quality conditions there.  A new report from the New York City Department of Health's Air Quality Program examines the effects of congestion pricing on fine particle air pollution in and around the tolling zone in the first few months of the program.

Sarah Johnson, Executive Director of the city Air Quality Program, joined WNYC host Michael Hill to unpack this initial data.
