Air Pollution In Nyc: A Historical Perspective

Air pollution has been a concern for New York City for a long time. The city has been trying to improve its air quality for decades, and while it has made significant strides, it still faces major challenges. NYC's air pollution issues are largely due to its high population density and heavy vehicle traffic, with most pollutants coming from cars, trucks, ships, and planes. The city has the lowest per capita vehicle miles traveled of any US city, but 2.5 million residents still drive into Manhattan every day. The transportation sector is the dominant contributor to emissions in the city, and while it is slowly being modernised and improved, emissions have increased in recent years. NYC's air pollution is also influenced by industrial emissions and unfavourable weather conditions, with higher temperatures in the summer months contributing to the formation of tropospheric ozone.

The 1966 New York City smog

Air pollution has been a long-standing issue in New York City, with the first legislation addressing smoke emissions being enacted in 1881. However, the city's air pollution problem became particularly prominent during the 1966 New York City smog event, a major air pollution episode and environmental disaster.

From November 23 to 26, 1966, smog covered New York City and the surrounding areas, including parts of New Jersey and Connecticut. A large mass of stagnant air over the East Coast trapped pollutants, filling the city's air with dangerously high levels of carbon monoxide, sulfur dioxide, smoke, and haze. This was the third major smog event in New York City, following similar episodes in 1953 and 1963.

The 1966 smog event had a significant impact on public health, with a study published in December 1966 estimating that 10% of the city's population suffered from adverse health effects such as stinging eyes, coughing, and respiratory distress. Subsequently, a statistical analysis published in October 1967 found that 168 deaths were likely caused by the smog. The medical community initially struggled to determine the exact impact of the smog, but it soon became clear that it had severe consequences for the residents of New York City.

The 1966 smog also highlighted the need for better air pollution monitoring and alert systems. Critics pointed out flaws in the existing SCS API alert system, which relied on a balance of multiple pollutants and could potentially disregard fatal levels of a single pollutant. As a result, there were calls for more effective systems to address air pollution and protect public health.

NYC's air quality in recent years

New York City's air pollution has been a concern for centuries, with the first legislation enacted to address smoke emissions in 1881. However, in recent years, the city's air quality has shown some improvement, despite remaining a challenge due to the city's high population density and heavy vehicle traffic.

In 2017, 2018, and 2019, New York City's air quality index (AQI) remained below 50, which is considered "good" by the US Environmental Protection Agency (EPA). During these years, the city's PM2.5 levels—a measure of fine particulate matter—averaged 6.8, 7, and 7 μg/m3, respectively, falling within the World Health Organization's (WHO) recommended limit of <10 μg/m3. However, it is important to note that the WHO advises that no level of exposure to PM2.5 is completely safe, and even low levels can have health impacts.

Despite these improvements, New York City's air pollution continues to disproportionately affect lower-income neighbourhoods, with higher rates of health complications related to air quality in these areas. Fine particles (PM2.5) in the air contribute to an estimated 2,000 excess deaths from lung and heart disease each year in NYC, as well as asthma incidents and other health issues.

The city has recognised the need to reduce air pollution and has implemented several measures to improve air quality. These include promoting the use of electric and hybrid vehicles, increasing access to public charging stations, and improving vehicle economics. New York City has set ambitious targets, aiming for 10,000 electric vehicle charging stations by the end of 2021 and 850,000 zero-emission vehicles by 2025. Additionally, the city has received recognition for its efforts, with the US Environmental Protection Agency awarding $9.35 million in 2019 to further enhance air safety.

While the COVID-19 pandemic and subsequent lockdown measures in 2020 led to a temporary decrease in pollution levels, it is expected that pollution levels will rise again as activities resume. To address this challenge, New York City continues to focus on legislation for 'cleaner' mass transport and reducing traffic congestion, with the goal of creating a safer and healthier living environment for its residents.

The impact of air pollution on vulnerable groups

Air pollution has been a concern for New Yorkers for a long time. While the city has made significant strides in improving air quality in recent decades, it still faces challenges, especially during the summer months. The transportation sector, which is the dominant contributor to emissions in the city, is slowly being modernised and improved. This, along with other sustainable initiatives, is helping to improve the air quality.

Despite New York City's efforts to reduce air pollution, it continues to pose a severe hazard to the health of its residents, particularly vulnerable groups. Vulnerable groups include children, older adults, and individuals with pre-existing conditions, such as respiratory disorders like asthma. These individuals are at an increased risk of experiencing the adverse health effects of air pollution.

Children, for example, are more susceptible to developing respiratory illnesses such as asthma due to air pollution. Studies have found that asthma-related hospitalisations are particularly common among children and teenagers. Additionally, vulnerable groups are at a higher risk of developing cardiovascular or respiratory diseases due to long-term exposure to air pollution, which can even lead to increased mortality.

Furthermore, lower-income neighbourhoods are disproportionately affected by air pollution, as they are often located in areas with higher levels of pollution, increasing the risk for heart and lung health complications among residents. Additionally, individuals with pre-existing mental health conditions may find their symptoms exacerbated by air pollution, leading to a decline in their quality of life.

While New York City continues to work towards reducing emissions and improving air quality, it is essential to prioritise the protection of vulnerable groups who are at the highest risk of suffering the adverse consequences of air pollution. This includes implementing policies and regulations that specifically target the reduction of pollutants that affect these vulnerable communities.

The transportation sector's contribution to emissions

New York City has long been a bustling hub of activity, with its history as a trading port and strategic position contributing to its growth over the centuries. However, this very prosperity has also brought challenges, particularly in the form of air pollution. While the city has made efforts to improve air quality, the transportation sector remains a significant contributor to emissions.

The transportation sector in New York is responsible for a large share of the state's carbon dioxide (CO2) emissions. In 2018, the transportation sector generated 83.3 million metric tons (MMT) of CO2, accounting for 47% of the state's total emissions. This marks a notable increase from 1990, when transportation emissions accounted for 31% of the state's total. While other sectors have reduced their emissions, transportation emissions continue to rise, posing a challenge to New York's goals for reducing greenhouse gas (GHG) emissions.

A range of vehicles contributes to transportation emissions, including personal cars, subways, rail, aircraft, and ships. Despite New York having the lowest per capita vehicle miles traveled among US cities, its high population density and heavy vehicle traffic contribute to congested roads and increased emissions. The city has recognized this issue and is promoting a transition to electric and hybrid vehicles, aiming for 850,000 zero-emission vehicles by 2025.

The impact of the transportation sector on air quality is not limited to CO2 emissions. Fine particulate matter (PM2.5) is another harmful pollutant, and transportation exhaust is a significant source. PM2.5 levels in New York have consistently met the stringent World Health Organization (WHO) guidelines since at least 2017, with an average of 6.8-7 μg/m3 during this period. However, any level of exposure carries health risks, and New York's air pollution levels continue to threaten the health of its residents, particularly in lower-income neighborhoods.

To address these concerns, New York City has implemented policies to reduce emissions from all energy sectors by 2050. These include increasing the efficiency of road vehicles and promoting the adoption of electric vehicles. The city aims to achieve 10,000 electric vehicle charging stations by the end of 2021. Additionally, the city is legislating for 'cleaner' mass transport, such as improving the energy efficiency of subways and rail systems. By addressing transportation emissions, New York City can improve air quality and protect the health of its residents.

The city's legislative approach to tackling air pollution

New York City has implemented a variety of legislative approaches to tackle its air pollution problem, which has been a significant environmental threat. The city has strict regulations in place to control emissions from vehicles and industries, including the Clean Heat programme, which aims to reduce the use of fossil fuels in home heating and cooling systems.

The city is also promoting the use of public transport, bicycles, and pedestrian routes to reduce emissions from combustion engines and encourage sustainable mobility. NYC has pushed a three-pronged approach to increase the adoption of electric vehicles, including community outreach, increasing access to public charging stations, and improving vehicle economics. The goal is to achieve 10,000 electric vehicle charging stations by the end of 2021 and 850,000 zero-emission vehicles by 2025.

New York City is also working to update and enforce the Air Pollution Control Code (Air Code), which aims to preserve, protect, and improve the city's air resources. The city's sustainability plan, PlaNYC, has also launched various emission reduction initiatives, and more are planned. These initiatives will not only benefit health but also help reduce greenhouse gas emissions.

In addition to these measures, the city has been legislating for 'cleaner' mass transport to reduce traffic congestion, which is a major contributor to air pollution. The city has introduced electric buses and taxis, and despite being the most populous city in the US, NYC has the lowest per capita vehicle miles travelled of any US city. The transition to electric and hybrid vehicles is expected to greatly improve New York's air quality.

The city has also received recognition for its efforts, with the US Environmental Protection Agency awarding New York City $9.35 million in 2019 to further improve air safety.
