New paper in ES&T Letters: the first full-year look at what NYC congestion pricing did to air quality. Led by the brilliant Polina Goldberg, we combined 15 roadside PM2.5 monitors with TROPOMI NO2 to ask if air in the Congestion Relief Zone got cleaner, and did pollution just move next door?

One year after the city launched congestion pricing, fine particulate pollution inside NYC’s congestion relief zone was 13% lower, finds a new study by @lamont.columbia.edu's Polina Goldberg, Abhishek Anand, @dwesty.bsky.social & @gwpublichealth.bsky.social's Daniel Goldberg: https://bit.ly/4i79dER

Map showing NO2 Reduction: Spatial distribution of tropospheric NO2 percent reduction across the New York City metropolitan area on cloud-free and stagnant-wind days, comparing 2025 with a 2018-24 baseline, excluding COVID19 lockdown period (Mar-Dec 2020).
