What You'll Learn
Ozone pollution and its health effects
While New York City's air quality has improved in recent decades, with a 13% drop in greenhouse gas emissions between 1990 and 2016, ozone pollution still causes about 2,400 deaths per year in NYC, as well as thousands of emergency department visits and hospitalizations for asthma, heart and lung problems.
Ozone is a gas composed of three atoms of oxygen. Stratospheric ozone occurs naturally in the upper atmosphere, where it forms a protective layer that shields us from the sun's harmful ultraviolet rays. However, ground-level ozone, which is created by chemical reactions between oxides of nitrogen (NOx) and volatile organic compounds (VOC) in the presence of sunlight, is a harmful air pollutant. This type of ozone is the main ingredient in smog and can trigger a variety of health problems, particularly for children, older adults, and people of all ages who have lung diseases such as asthma.
Ground-level ozone develops in the atmosphere from gases that come out of tailpipes, smokestacks, factories, power plants, industrial boilers, refineries, chemical plants, and other sources. When these gases come in contact with sunlight, they react and form ozone smog. The impact of ozone exposure on health depends on various factors, including the ozone levels in the environment, breathing rate, and the amount of time spent outdoors. Even relatively low levels of ozone can have health effects, and the risk of harm increases with higher levels of ozone.
Health issues associated with ozone pollution can be severe, and vulnerable groups include children, older adults, people with asthma, and individuals with preexisting conditions. Ozone can cause coughing, shortness of breath, worsen asthma or bronchitis symptoms, and irritate and damage the airways. It can also lead to more serious health problems, with studies showing that long-term exposure to ozone increases the risk of premature death and cardiovascular or respiratory disease mortality.

Public Transportation
One way to reduce vehicle emissions is to encourage the use of public transportation. New York City's public transit network is one of the most sustainable in the country, and it helps the city avoid 19 million metric tons of emissions per year. By investing in more environmentally friendly energy sources for buses and trains, the city can further reduce emissions from combustion engines.
Electric Vehicles
The transition to electric vehicles (EVs) is another important strategy. Governor Kathy Hochul has proposed a plan to ban fossil fuel automobiles by 2035 and make the city more EV-friendly. Students can support this initiative by advocating for more EV charging stations in their communities and educating their peers and families about the benefits of EVs.
Cycling and Walking
Promoting cycling and walking as alternative modes of transportation can also help reduce vehicle emissions. New York has seen a steady rise in cycling, and efforts are being made to improve infrastructure and introduce laws to make cycling safer. Students can get involved by joining cycling advocacy groups and participating in campaigns to make their schools and neighborhoods more bike-friendly.
Traffic Congestion
Addressing traffic congestion is crucial to reducing vehicle emissions. New York City has introduced a congestion fee to discourage the use of motor vehicles, with the funds aimed at improving public transportation. Students can support similar initiatives and advocate for carpooling and ride-sharing options to reduce the number of vehicles on the road.
Sustainable Practices
Educating students about sustainable practices can also help reduce vehicle emissions. Schools can partner with organizations like the New York State Pollution Prevention Institute (NYSP2I) to provide educational resources and raise awareness about the impact of chemical pollution. By learning about alternative chemicals, green marketing, and waste prevention, students can make informed choices and influence their communities to adopt more sustainable practices.

Sustainable public transport
New York City's air quality has improved over the last few decades, with a 13% reduction in greenhouse gas emissions between 1990 and 2016. However, during this period, emissions from the transportation sector increased, contributing to higher ozone pollution. To address this issue, the city has implemented several initiatives to promote sustainable public transportation.
One of the most iconic and sustainable modes of public transport in New York City is the subway. The NYC Subway is entirely electric, keeping approximately 70,000 cars off the streets daily and reducing CO2 emissions by up to 253 tonnes per day. The Metropolitan Transport Authority (MTA) has also introduced energy-efficient measures such as LED lighting and regenerative braking technology, further reducing the carbon footprint of the subway system. The electricity that powers the subway trains is sourced from the NYC grid, which obtains up to 70% of its energy from renewable sources. This makes the subway a much more environmentally friendly option than cars, with passenger mile emissions five times lower.
Cycling is another sustainable and healthy mode of transportation that is gaining popularity in New York City. The city has expanded its bike network to 980 lane miles, making biking a convenient option for many commuters. This initiative supports the city's sustainability goals by reducing carbon emissions and improving air quality.
To further discourage the use of private motor vehicles, the government has introduced a congestion fee, the first of its kind in the United States. The revenue generated from this fee will be used to improve and maintain the public transport network, making it an even more attractive option for commuters. Additionally, Governor Kathy Hochul has proposed a plan to ban fossil fuel automobiles by 2035, with the goal of making the city more EV-friendly.
New York City's public transportation network is vital to the city's economy and the daily lives of its residents. The city's sustainability plans include improving existing infrastructure and technology to reduce emissions further. The goal is to achieve 80% of trips on sustainable modes (walking, biking, or mass transit) by 2050, with the remaining vehicular trips being zero-emissions.

Air quality monitoring
The New York City Community Air Survey (NYCCAS) is one such initiative. Established in 2008, it is the largest ongoing urban air monitoring program in the United States. The NYCCAS collects data on six key pollutants: fine particulate matter (PM2.5), black carbon, O3 or tropospheric ozone, sulfur dioxide (SO2), nitrogen oxides (NOx), and carbon monoxide (CO). These pollutants are known to have severe health impacts, particularly on vulnerable groups such as children, older adults, and individuals with pre-existing health conditions.
The NYCCAS monitoring sites are strategically placed in various environments across New York City, including sidewalks, busy streets, parks, and quiet neighborhood roads. This comprehensive approach ensures that the data collected is representative of the diverse air quality conditions across the city. The data gathered by the NYCCAS has shown positive results, with a decrease in ozone pollution over the last decade, indicating that the city's sustainability plans are moving in the right direction.
Additionally, the Department of Environmental Conservation (DEC) also plays a crucial role in air quality monitoring. The DEC utilizes high-quality, professionally calibrated monitoring equipment to produce reliable and repeatable data across almost 100 pollutants. Their monitoring network covers a wide range of locations and provides valuable insights into neighborhood variations in air quality.
To further enhance air quality monitoring, advanced air monitoring systems, such as those offered by Kunak, can be employed. These systems use autonomous air quality sensors to provide real-time data, enabling timely decision-making by administrative bodies. The data also activates early warning systems, notifying citizens about air quality levels and recommended measures on days with high pollution levels.
Students can play an active role in air quality monitoring by participating in research initiatives and community projects. For example, the Rochester Institute of Technology (RIT) has student-led teams conducting research in green chemistry to discover more sustainable chemical products and processes. Additionally, the New York State Pollution Prevention Institute (NYSP2I) offers educational resources and customized solutions to businesses, communities, and nonprofits, empowering them to make sustainable choices and improve their environmental impact.
