What You'll Learn
Pollution from buildings
New York City is the most populous city in the United States, and its residents face severe health threats from air pollution. While the city has made strides in reducing pollution, with a 13% decrease in greenhouse gas emissions between 1990 and 2016, it was ranked as the eighth most polluted city in the country.
A significant source of pollution in NYC is its buildings, which are responsible for a large portion of the state's fossil fuel consumption. The combustion of fuels for space and water heating in residential and commercial buildings accounts for nearly 40% of the city's total greenhouse gas emissions. This has led to severe health impacts, with a study estimating that fuel combustion in NYC buildings caused 1,114 premature deaths and $12.5 billion in health impact costs in 2017.
The emissions from these buildings contain harmful pollutants such as fine particulate matter (PM2.5), oxides of nitrogen and sulfur (NOx and SOx), volatile organic compounds, and ammonia. NOx emissions are particularly detrimental as they lead to secondary PM2.5 formation and react with other compounds to create ozone, the primary ingredient in smog. NYC's buildings produce NOx pollution at a significantly higher rate than the city's vehicles and power plants, making them a major contributor to the city's air pollution and a crucial area to address for improved health and air quality.
To combat this issue, NYC Council Member Alicka Ampry-Samuel is leading an effort to pass legislation prohibiting gas hookups in new buildings and promoting an all-electric future. The goal is to reduce the health impacts of burning fuels and create a cleaner, healthier, and more equitable city. Additionally, the city has implemented rules requiring boilers to burn low-sulfur oil or natural gas, which is expected to reduce fine particles emitted from heating buildings by at least 63%.

Ozone pollution
Tropospheric or ground-level ozone pollution is formed when nitrous oxide (NOx) and volatile organic compounds (VOCs) interact. These pollutants are emitted from vehicles, industries, power plants, gasoline equipment, and products like solvents and paints. The transportation sector has been identified as a significant contributor to ozone pollution in NYC, with emissions from fossil fuel-powered vehicles playing a major role. Additionally, NOx emissions from residential and commercial buildings in NYC are a major concern, with buildings generating twice as much NOx pollution as the city's light-duty passenger vehicles.
To address ozone pollution, the EPA has implemented regulations, and New York State alerts the public when ozone levels are expected to be unhealthy. The state also recommends that schools and childcare providers suspend outdoor activities when air quality is poor. NYC has also introduced a congestion fee to discourage the use of motor vehicles and plans to ban fossil fuel automobiles by 2035, promoting an EV-friendly future. There is also a push for all-electric buildings to reduce emissions from fuel combustion, which has been linked to premature deaths and adverse health impacts in the city.
Despite these efforts, ozone pollution remains a challenge in NYC. The city's high population and dense urban environment contribute to the complex mixture of man-made pollutants and natural sources that make up the city's air pollution. Additionally, external sources of pollution, such as emissions from neighbouring states, can impact NYC's air quality, making it a regional and cross-state issue. Overall, ozone pollution in NYC is a complex problem that requires continued efforts and collaboration to improve air quality and protect the health of its residents.

Transport emissions
New York City's transportation sector is responsible for a large share of the state's carbon dioxide (CO2) emissions. Between 1990 and 2018, transportation emissions in New York State rose by 31%, from 63.8 million metric tons (MMT) to 83.3 MMT, with a slight decrease in gasoline emissions offset by an increase in diesel fuel emissions. The transportation sector includes vehicles such as cars, buses, trucks, subways, rail, aircraft, and ships.
In NYC, private vehicles and trucks are the major contributors to transport emissions, accounting for 83% and 13% respectively of the sector's emissions. The use of private vehicles has been increasing, with an 8.8% rise in new registered vehicles, while the use of public transportation has been declining. This shift away from public transit has contributed to the increase in transport emissions.
To address this issue, NYC has implemented various measures. The city introduced a congestion fee to discourage the use of motor vehicles and plans to use the revenue to improve public transportation. Governor Kathy Hochul proposed banning fossil fuel automobiles by 2035, promoting electric vehicles. Local laws have been enacted to reduce emissions from diesel fuel-powered vehicles, such as requiring the use of ultra-low sulfur diesel fuel and the implementation of emission control technology.
Additionally, NYC has set ambitious targets to reduce greenhouse gas emissions by 80% by 2050. The city aims to achieve this through mode shifts like increased biking and walking, reduced light-duty vehicle demand, fuel switching, and the adoption of more efficient vehicles. The electrification of light-duty vehicles and energy efficiency improvements are crucial for significant emission reductions.
While these efforts are underway, the increase in transportation emissions in NYC remains a challenge, impacting air quality and the health of residents.

Land pollution
One significant contributor to land pollution in NYC is the density of warehouses in certain areas. Neighborhoods with a high concentration of warehouses, such as Newtown Creek in Queens and Brooklyn, Red Hook/Sunset Park in Brooklyn, and Hunts Point in the Bronx, experience higher levels of pollution. The industrial nature of these areas, with frequent diesel truck traffic, contributes to the pollution levels. Additionally, areas with a large number of restaurants and higher building density tend to have higher pollutant concentrations.
Another critical source of land pollution in NYC is the city's buildings. NYC emits more air pollution from residential and commercial buildings than any other state, primarily due to combustion emissions. These emissions include harmful pollutants such as fine particulate matter (PM2.5), oxides of nitrogen and sulfur (NOx and SOx), volatile organic compounds, and ammonia. The presence of these pollutants has severe respiratory health effects on residents, leading to asthma attacks, hospitalizations, and even premature deaths. NYC buildings generate twice as much NOx pollution as the city's light-duty passenger vehicles and a staggering seven times more than its power plants.
To address building pollution, there is a growing effort to transition to all-electric buildings. Led by NYC Council Member Alicka Ampry-Samuel and supported by local environmental organizations, there is a push to prohibit gas hookups in new buildings and promote a healthier and more sustainable future. This shift is crucial, as burning fuels in space and water heating appliances, such as furnaces and boilers, is a significant contributor to land pollution.
Furthermore, NYC has implemented several measures to reduce emissions from local sources of pollution. The city has passed legislation to control emissions from idling vehicles, diesel-powered buses, school buses, and municipally owned heavy-duty fleets. Additionally, the introduction of a congestion fee aims to discourage the use of motor vehicles, with funds being redirected to improve public transportation. These initiatives reflect NYC's commitment to reducing land pollution and creating a healthier environment for its residents.

Air pollution from outside NYC
New York City's air quality has improved in recent decades, but air pollution continues to affect the health of millions of people in the city and nationwide. Outdoor air pollution has been linked to serious health problems, including heart disease, asthma, and low birth weight.
About 30% of PM2.5 in NYC comes from outside sources, such as coal-burning power plants in the Midwest. These outside sources account for more of the city's air pollution than local sources, although local sources contribute to the differences in PM2.5 concentration between locations within the city. Weather patterns can bring wildfire smoke from far-away fires, and trap emissions, causing PM2.5 to build up.
In NYC, the government has introduced a congestion fee to discourage the use of motor vehicles and reduce emissions. This is the first initiative of its kind in the United States, and the plan is to use the money to improve and maintain the public transport network. However, many residents oppose the plan. In addition, Governor Kathy Hochul has proposed banning fossil fuel automobiles by 2035 and making the city EV-friendly. Despite these measures, there has been a decline in the use of subways and buses, with a corresponding rise in the use of private vehicles, app-based ride-hailing services, and road congestion.
Ozone and PM2.5 are the two most prevalent air pollutants in NYC, causing about 2,400 deaths per year in the city, as well as thousands of hospitalizations for asthma, heart, and lung problems. Ozone is produced when sunlight mixes with air contaminants from vehicle exhaust and other sources. PM2.5 is caused by smoke from fires, including building fires, wildfires, and fireworks, as well as emissions from fuel burning. Exposure to PM2.5 over time can worsen serious health problems, including heart and lung diseases, shortening life expectancy.
