What You'll Learn
NYC's air quality has been compared to China's
New York City's air quality has been a concern for decades, with the city's large population, industrialization, and vehicle emissions contributing to high levels of pollution. In 1966, a major smog event in NYC caused adverse health effects for an estimated 10% of the city's population, including respiratory issues and even deaths. This event brought national attention to air pollution as a serious health and political issue, leading to the 1967 Air Quality Act and the 1970 Clean Air Act.
While NYC has made significant strides in improving air quality since the 1960s, it still faces challenges. The city's air pollution is primarily caused by mobile emission sources, such as cars, trucks, and heavy-duty vehicles, as well as stationary sources like residential fuel combustion and commercial cooking. The New York City Community Air Survey (NYCCAS) has identified benzene, formaldehyde, and other toxic air pollutants as common issues in the city.
Comparisons have been drawn between NYC's air quality and that of Chinese cities, particularly Beijing. In 2012, legal scholar Elizabeth M. Lynch noted that images of visible air pollution in Beijing were not very different from pictures of NYC in the 1950s and 1960s. Lynch's comments highlight the progress made in the United States to regulate and abate pollution and express optimism that China can follow a similar path.
NYC's air quality has also been compared to Chinese cities during periods of extreme pollution events. In June 2023, NYC experienced the worst air quality in the world due to a historic wildfire smoke outbreak across Northeast and Central Canada. During this time, the Air Quality Index (AQI) in NYC exceeded 480, surpassing even that of notoriously polluted cities in China. The smoke was so dense that visibility dropped below one mile in Central Park, and outdoor activities had to be cancelled for the city's 1.1 million public school students.
While NYC's air quality has shown improvement over time, with a 40% reduction in PM2.5 pollution over the last 20 years, more action is needed to address the health effects of pollution. The city has implemented creative solutions, such as deploying hybrid buses and electric vehicles, and promoting cleaner transportation options. NYC also benefits from strict laws and enforcement from the state's proactive air pollution control program, which has resulted in reduced levels of nitrogen oxide, NO2, and black carbon.

NYC's air pollution and health risks
New York City has long been plagued by air pollution, with the problem becoming particularly acute during the 1950s and 1960s. The infamous 1966 New York City smog event caused adverse health effects such as stinging eyes, coughing, and respiratory distress in 10% of the city's population, and likely caused 168 deaths. This event brought national attention to the issue of air pollution and led to the passing of federal legislation regulating air pollution, including the 1967 Air Quality Act and the 1970 Clean Air Act.
While air quality in New York City has improved since the 1960s, air pollution remains a significant concern. The city's large population, industrialization, and high volume of vehicle traffic contribute to high levels of pollutants in the air, including nitrogen oxide (NOx), nitrogen dioxide (NO2), sulfur dioxide (SO2), particulate matter (PM2.5), and hazardous air pollutants (HAPs) such as benzene and formaldehyde. These pollutants have been linked to various health risks, including respiratory illnesses, heart disease, and increased cancer risk.
Children are particularly vulnerable to the health effects of air pollution. In the Bronx, for example, children have significantly higher rates of asthma morbidity compared to children in other US cities. Overall, the rate of asthma among 4-5-year-old children in the Bronx is 15.5%, compared to 9.2% for NYC students overall and 8.9% for US kids between the ages of 2 and 17.
NYC's air pollution problem is not limited to ground-level emissions. The city is also affected by smog events caused by weather conditions that trap pollutants in the lower atmosphere. During such events, air quality can deteriorate to hazardous levels, as happened in June 2023 when smoke from wildfires in Canada blanketed the city, causing the Air Quality Index (AQI) to soar above 480, the highest level recorded in NYC's history.
To address the issue of air pollution and mitigate health risks, NYC has implemented various initiatives and policies. These include the Clean Bus Program, which reduced nitrogen oxide, NO2, and black carbon emissions from the city's bus fleet, and the Clean Heat Program, which lowered ambient levels of SO2, PM2.5, and NO2 by phasing out dirty residual heating oil in buildings. The city has also deployed hybrid buses and city cars, and is promoting cleaner transportation options to reduce emissions from vehicles, which are a major source of pollution. Additionally, NYC has set an ambitious target to reduce greenhouse gas emissions by 85% by 2050, demonstrating its commitment to improving air quality and safeguarding public health.
