Pollution In Nyc: The Unseen Side Of The City That Never Sleeps

New York City is the most populous city in the United States, and its environmental issues are influenced by its size, density, abundant public transportation infrastructure, and location at the mouth of the Hudson River. The city's air pollution, which has been a long-standing threat to the well-being of its residents, is largely caused by mobile emission sources such as cars and trucks, as well as the burning of fossil fuels in residential and commercial buildings. The transportation sector is the dominant contributor to emissions, and ozone pollution, in particular, has severe health impacts, causing premature deaths, hospitalisations, and asthma flare-ups. The city has implemented initiatives to improve air quality, such as introducing a congestion fee and aiming for a transition to electric vehicles and all-electric buildings.

Fossil fuel-powered vehicles and factories emit nitrous oxide and volatile organic compounds

New York City's air pollution has posed a threat to the well-being of its residents for a long time. While the city has made progress in improving air quality, certain aspects continue to cause pollution. One significant contributor is the emission of nitrous oxide and volatile organic compounds (VOCs) from fossil fuel-powered vehicles and factories.

Tropospheric or ground-level ozone pollution is primarily caused by the interaction of nitrous oxide (NOx) and volatile organic compounds. These pollutants are emitted into the atmosphere when fossil fuels are burned, contributing to the formation of smog and poor air quality. The transportation sector, including vehicles powered by fossil fuels, is the dominant contributor to emissions in New York City. This sector has seen an increase in emissions, which has exacerbated the presence of ozone pollution in the atmosphere.

Vehicles burning fossil fuels, such as gasoline, release nitrous oxide into the atmosphere. Nitrous oxide is a potent greenhouse gas that has a significant impact on global warming. In 2022, nitrous oxide accounted for 6% of all U.S. greenhouse gas emissions from human activities. While nitrous oxide emissions have natural sources, human activities, particularly fuel combustion, have increased its presence in the atmosphere. The burning of fossil fuels in vehicles and industrial processes contributes to this increase.

In addition to nitrous oxide, fossil fuel-powered vehicles and factories also emit volatile organic compounds (VOCs). VOCs are organic chemicals that have a high vapour pressure and can easily become gaseous at room temperature. Common sources of VOCs include household products like cleaners, paint, and glue, as well as industrial processes. Exposure to VOCs can have negative effects on indoor and outdoor air quality, potentially leading to health issues.

To address the emissions of nitrous oxide and VOCs, New York City has implemented several measures. The city introduced a congestion fee to discourage the use of motor vehicles and promote public transportation or alternative modes of transport. Additionally, Governor Kathy Hochul proposed a plan to ban fossil fuel automobiles by 2035, aiming to transition to electric vehicles and improve air quality. These initiatives, along with sustainability plans and regulations, are expected to reduce emissions and improve the health and well-being of New Yorkers.

New York City's buildings emit dangerous pollutants from burning fuels

New York City is the largest city in the United States, and its environmental issues are influenced by its size, density, abundant public transportation infrastructure, and location at the mouth of the Hudson River. The city's population density has both pros and cons: while it facilitates the highest mass transit use in the country, it also concentrates pollution.

The health effects of building air pollution are not evenly distributed among the population. Communities of color in New York City are disproportionately exposed to PM2.5 emissions from residential gas combustion. They are exposed to 17% more PM2.5 than the population average, with Black New Yorkers facing 32% higher exposure. This disparity underscores the urgency of transitioning to all-electric buildings and safeguarding marginalized communities' health.

The push for all-electric buildings in New York City is gaining momentum. An analysis revealed that constructing all-electric single-family homes is more cost-effective than building mixed-fuel homes. Additionally, all-electric buildings would eliminate the costs of gas piping and separate appliances for heating and cooling. By mandating all-electric new constructions, the city can mitigate the adverse health and air quality impacts associated with burning fuels in buildings.

While New York City grapples with building pollution, it is also addressing air pollution from other sources. The transportation sector, historically a major contributor to emissions, is undergoing modernization and improvements. The government has introduced a congestion fee to discourage the use of motor vehicles and plans to ban fossil fuel automobiles by 2035. These initiatives, along with sustainable practices by federal and local governments, are helping to improve the city's air quality.

The transportation sector is the dominant contributor to emissions in the city

The transportation sector is the dominant contributor to emissions in New York City. The city's transportation sector, which includes the energy consumption of vehicles like personal cars, subways, rail, aircraft, and ships, generated 83.3 million metric tons of CO2 in 2018, the year with the most recent data available. This accounts for 47% of the state's total emissions, a significant increase from 31% in 1990. Private vehicles and trucks are the major contributors, accounting for 83% and 13% of transportation emissions, respectively.

While New York City's per capita transportation emissions are relatively low compared to other US cities due to the high use of mass transit, the absolute emissions remain substantial. The increase in transportation emissions is likely due to a combination of factors, including the rise in fuel-intensive vehicle usage, such as SUVs and trucks, and the overall growth in travel demand. The average vehicle miles travelled per person in NYC is nine miles per day, approximately one-third of that in other large metropolitan areas in the US. However, the high population density in the city means that pollution is concentrated.

To address this issue, New York City has implemented several initiatives. The city introduced a congestion fee, the first of its kind in the US, to discourage the use of motor vehicles and generate funds to improve public transportation. Governor Kathy Hochul has also proposed a plan to ban fossil fuel automobiles by 2035 and promote the adoption of electric vehicles. Additionally, there has been a steady rise in cycling, and efforts are being made to improve infrastructure and safety for cyclists.

Despite these efforts, the transportation sector's emissions continue to increase, posing a challenge to achieving ambitious greenhouse gas reduction goals. New York State's Climate Leadership and Community Protection Act (CLCPA) of 2019 aims to reduce statewide GHG emissions by 40% from 1990 levels by 2030 and by 85% by 2050. To meet these targets, reducing transportation emissions is crucial. Various emission scenarios have been modelled, considering factors such as electric vehicle adoption rates, grid decarbonization, and energy efficiency improvements to guide policy-making and achieve the desired emission reductions in the transport sector.

Population density concentrates pollution

Population density has a significant impact on pollution concentration. New York City, with its high population density, serves as a prime example of how population density can influence pollution levels.

New York City is the largest city in the United States, housing 2.7% of the country's population. This dense concentration of people has both pros and cons from an environmental perspective. On the one hand, the city's high population density facilitates the highest mass transit use in the nation, which can help reduce pollution per capita. On the other hand, the sheer number of people in a relatively compact area inevitably leads to a concentration of pollution.

The impact of population density on pollution is a complex relationship that has been the subject of numerous studies. Some research suggests that higher population density worsens local air quality, particularly in megacities and developing countries. This is due to various factors, including increased gasoline consumption, higher energy use, and emissions from transportation and industrial activities. In contrast, other studies have found that population density can improve air quality by increasing the demand for and consumption of clean energy and public transportation, thereby reducing gas emissions per capita.

In the case of New York City, several factors contribute to the concentration of pollution. Firstly, the city's dense population increases gasoline consumption and energy use, especially in the transportation sector. New York's transportation sector, including fossil fuel-powered vehicles, is a dominant contributor to emissions. Additionally, the city's industrial and commercial activities, such as factories, contribute to the emission of pollutants like nitrous oxide (NOx) and Volatile Organic Compounds (VOCs). The interaction of these pollutants creates ground-level ozone pollution, which has severe health impacts on residents, causing asthma flare-ups, respiratory issues, and even contributing to premature deaths.

Furthermore, the effects of pollution are not evenly distributed within the city. Low-income neighborhoods like Northern Manhattan and the Bronx bear a disproportionate share of pollution sources, which has been attributed to environmental racism. The placement of roadways, toxic waste facilities, bus depots, and industrial sites in these predominantly Black and Brown communities has resulted in higher pollution concentrations and consequent health issues, such as asthma, for the residents.

Low-income neighbourhoods bear a disproportionate share of pollution sources

New York City is the largest city in the United States, and despite housing 2.7% of the country's population, it accounts for only 1% of the country's greenhouse gas emissions. However, within the city, the burden of air pollution is not evenly shared. Low-income neighbourhoods, like those in Northern Manhattan and the Bronx, bear a disproportionate share of pollution sources. The Bronx is one of the poorest counties in the United States, and it has the highest rate of asthma-related emergency room admissions in New York City and the state. Asthma is the leading cause of hospitalizations and school absences for children in the Bronx.

This disproportionate burden of pollution on low-income neighbourhoods is the result of various factors, including the lack of emissions regulations and enforcement, the placement of pollution sources near these neighbourhoods, and the political power of large emitters. This phenomenon is known as environmental racism, where Black and Brown communities are deliberately targeted when deciding where to place roadways, toxic waste facilities, industrial sites, and commercial sites. The combination of these factors results in low-income individuals suffering from physical and mental health consequences, as well as impaired cognitive function.

The issue of low-income communities' disproportionate exposure to air pollution is not unique to New York City but is prevalent across the United States. Studies have found that non-white and low-income communities are more likely to be exposed to hazardous particles and fine particle pollution. For example, a study of New Jersey residents found a higher risk of premature death from long-term exposure to particle pollution in communities with larger African American populations, lower home values, and lower median incomes. Similarly, in Atlanta, particle pollution increased the risk of asthma attacks in zip codes with high poverty rates and among people eligible for Medicaid.

The impact of air pollution on vulnerable populations in New York City has been the subject of various studies. The American Lung Association's 2024 annual report ranks the New York City region as 13th out of the 25 most polluted cities by ozone. Additionally, residents of New York County (Manhattan) have the third-highest cancer risk caused by airborne chemicals among all counties in the United States. Bronx and Kings Counties rank 8th and 9th, respectively, while Queens County ranks 13th. These disparities in the impact of air pollution highlight the need for initiatives to enhance the sustainability and environmental quality of megacities like New York City.
