What You'll Learn
New York City's air quality has improved over the years
New York City has the highest population in the United States, and despite its dense population, the city typically has reasonably clean air. New York City's air quality has improved over the years, with the city and state working to reduce emissions from local and regional sources.
In the middle of the 20th century, New York City had the most polluted air of any big city in the United States. Pollution from coal-fired power plants, municipal and residential waste incinerators, motor vehicles, maritime traffic, highly polluting industries, commercial cooking, and oil-fired boilers in buildings resulted in two "killer smog" incidents in November 1953 and 1966, causing an estimated 400 deaths. Following the 1966 smog incident, city officials strengthened the NYC Air Pollution Control Codes, and the United States Environmental Protection Agency (US EPA) was established, along with the passing of the Clean Air Act in 1970.
Since then, EJ communities have pushed for reforms to improve New York City's air quality, resulting in the closing of all municipal waste incinerators in the city in 1994 and the passing of legislation to phase out fossil fuels. NYCCAS has recorded steep decreases in annual average levels of all measured pollutants since the first year of monitoring in 2009, except for O3, which results from emissions outside the city. Annual average levels of PM2.5 have been reduced by 43%, NO2 by 39%, NO by 56%, and SO2 by 98%. These reductions are due in large part to Local Law 38 of 2015, which resulted in significant revisions to the New York City Air Pollution Control Code.
New York City's high rate of transit use has also contributed to improved air quality. In 2006, the city saved 1.8 billion US gallons (6,800,000 m3) of oil, resulting in 11.8 million metric tons of carbon dioxide pollution kept out of the air. The city's greenhouse gas emissions are 7.1 metric tons per person, well below the national average of 24.5. New York City accounts for only 1% of US greenhouse gas emissions while housing 2.7% of its population.
However, air pollution remains a concern, especially in low-income neighborhoods like those in Northern Manhattan and the Bronx, where there is a disproportionate share of pollution sources due to environmental racism. The Bronx has the highest rate of asthma-related emergency room admissions in the city and state, with asthma being the leading cause of hospitalizations and school absences for children in the area.
To further improve air quality, New York City has promoted cleaner transportation options and pushed for a transition to electric and hybrid vehicles. The city aims to achieve 10,000 electric vehicle charging stations by the end of 2021 and 850,000 zero-emission vehicles by 2025.

The city's dense population and low automobile dependence make it energy efficient
New York City has the highest population in the United States, but it typically enjoys reasonably clean air. The city's dense population and low automobile dependence make it one of the most energy-efficient cities in the country.
The city's high rate of transit use has saved billions of gallons of oil and gasoline costs. New York saves half of all the oil saved by transit nationwide. The reduction in oil consumption means millions of metric tons of carbon dioxide pollution are kept out of the air. The city's extraordinary public transit use means that New Yorkers emit far fewer greenhouse gases on a per capita basis than the average American. New York City's greenhouse gas emissions are 7.1 metric tons per person per year, compared with the national average of 24.5. New Yorkers collectively account for 1% of the nation's total greenhouse gas emissions, despite making up 2.7% of the population.
The average New Yorker consumes less than half the electricity used by a resident of San Francisco and nearly a quarter of that consumed by a resident of Dallas. The city's mass transit system, multifamily housing, mixed neighborhoods, and lack of greenfield land available for development make building in New York very energy efficient.
New York has introduced a series of environmental policies since the 1990s to address growing energy demands and limited space. For example, the city has switched more than 11,000 traffic lights and pedestrian signals to new energy-efficient light-emitting diodes that use 90% less energy than conventional fixtures. Local Law 38 of 2015 resulted in significant revisions to the New York City Air Pollution Control Code, regulating previously unregulated sources of emissions, requiring building owners to convert to cleaner heating oils, and regulating Tier IV sources.
Despite these advancements, air pollution remains a severe hazard to the health of New Yorkers. Asthma flare-ups, lower respiratory infections, lung cancer, stroke, and chronic obstructive pulmonary disease are just some of the disorders caused by air pollution. The World Health Organization (WHO) has provided evidence linking air pollution exposure to type 2 diabetes, obesity, systemic inflammation, Alzheimer’s disease, and dementia.

Environmental racism in low-income neighborhoods
New York City has a history of environmental racism, with low-income neighbourhoods bearing a disproportionate share of pollution sources. This is due to the deliberate targeting of Black and Brown communities when deciding the placement of roadways, waste facilities, and industrial sites. Northern Manhattan and the Bronx, for example, are heavily polluted areas, with the South Bronx being particularly affected. The Bronx is one of the poorest counties in America and has the highest rate of asthma-related emergency room admissions in New York City and State.
The history of environmental racism in New York City is deeply rooted in the city's colonization and structural racism. In the past, racist perceptions of Black and immigrant communities have influenced lending practices and property values, with redlining further perpetuating the notion that low-income communities of colour are less valuable. This has resulted in these neighbourhoods being targeted for the placement of polluting infrastructure and industries.
The high population density of New York City has also played a role in the concentration of pollution in these low-income neighbourhoods. While the city has the highest mass transit use in the United States, which has helped reduce gasoline consumption and greenhouse gas emissions, it also concentrates pollution. The industrial land uses and vehicle infrastructure are mutually reinforcing, with vehicle infrastructure attracting industrial uses and vice versa. This has resulted in heavy bus and truck traffic in New York's low-income communities and communities of colour.
In recent years, New York City has made efforts to reduce its environmental impact and improve air quality. Local Law 38 of 2015 revised the New York City Air Pollution Control Code, regulating previously unregulated emission sources and requiring the use of cleaner heating oils. As a result, there have been steep decreases in annual average levels of most measured pollutants. However, ozone (O3) levels, largely resulting from emissions outside the city, remain a concern, especially during the summer months.
Despite these efforts, air pollution continues to pose severe health hazards to New York City residents, particularly in low-income neighbourhoods. Asthma and other respiratory conditions are prevalent in these areas, with residents reporting fair-to-poor housing conditions. Environmental justice communities are now enlisting local governments to address and reverse these environmental health and safety hazards.

Ozone pollution is a critical component of smog
New York City is the largest city in the United States, with a significant population. Despite this, the city has relatively clean air compared to other large cities. In recent years, New York has focused on reducing its environmental impact. The city's dense population and low automobile dependence contribute to its energy efficiency. New Yorkers emit fewer greenhouse gases per capita than the average American, with greenhouse gas emissions of 7.1 metric tons per person per year, compared to the national average of 24.5.
However, air pollution remains a concern in New York, and it still poses severe health hazards to residents. Various diseases, including respiratory, circulatory, neurological, gastrointestinal, and urinary illnesses, have been linked to air pollution. In addition, certain neighbourhoods bear a disproportionate share of pollution sources. For example, the Bronx, one of the poorest counties in America, has the highest rate of asthma-related emergency room admissions in New York City and the state.
Ozone pollution, a critical component of smog, is one of the most dangerous and widespread pollutants in the United States. Ground-level ozone is a harmful air pollutant that is formed when oxides of nitrogen (NOx) and volatile organic compounds (VOCs) react in the presence of sunlight. This typically occurs in urban environments on hot, sunny days, but ozone can also reach high levels during colder months and in rural areas due to wind.
Ozone is a major component of photochemical smog, along with nitrogen dioxide (NO2), peroxyacetylnitrate (PAN), and aldehydes. It is the most toxic constituent of photochemical smog and has caused significant damage to agricultural and native plants. Ozone irritates and damages the membranes of the respiratory system and eyes, and exposure to it can cause respiratory distress, especially in vulnerable individuals. Studies have also shown a link between ozone exposure and premature death, with the risk increasing with higher ozone levels.
In New York City, ozone is always present in the air, with higher concentrations in the summer. Efforts to reduce air pollution in the city, such as Local Law 38 of 2015, which regulated previously unregulated sources of emissions, have led to decreases in most measured pollutants. However, ozone levels, largely resulting from emissions outside the city, have remained steady.

The transportation sector is the dominant contributor to emissions
New York City has worked to reduce emissions from local and regional sources, and the air quality has improved over the past few decades. Despite this, air pollution still poses a severe hazard to the health of New Yorkers. The transportation sector is the dominant contributor to emissions in New York State, responsible for 83.3 million metric tons of CO2 in 2018, the year with the most recent data available. This is a 31% increase since 1990. The transportation sector includes the energy consumption of vehicles whose primary purpose is transporting people or goods, including personal vehicles, subways, rail, aircraft, and ships.
Transportation accounted for 29% of emissions in 2022, making it the third-largest contributor to US greenhouse gas emissions when considering indirect emissions. When considering only direct emissions, transportation is the largest contributor to US greenhouse gas emissions (28%). The number of vehicle miles traveled by light-duty motor vehicles has increased by 47% from 1990 to 2022, due to population growth, economic growth, urban sprawl, and periods of low fuel prices.
The increase in transportation emissions is particularly notable when compared to other sectors. For example, emissions from the electric power sector declined by 62% from 1990 to 2018. While residential emissions increased by 8% over this period, transportation emissions rose by a much larger proportion. As a result, the transportation sector's share of total state emissions increased from 31% in 1990 to 47% in 2018.
New York's high rate of transit use has helped to reduce emissions and save oil. In 2006, New York's high transit use saved 1.8 billion US gallons of oil and $4.6 billion in gasoline costs. The reduction in oil consumption kept 11.8 million metric tons of carbon dioxide pollution out of the air. New York's greenhouse gas emissions per capita are also relatively low compared to other cities and the national average. New York's dense population and low automobile dependence contribute to its energy efficiency.
