Hawaii's clean air can be attributed to its preservation efforts, maintaining its pristine beaches and tropical atmosphere. However, increasing climate change threatens the state's air quality. As a comparison, North Dakota ranks third for cleanest air in the US, with an Air Quality Index of 37, and is also in the top ten states with the lowest air pollution.

Vermont has also consistently ranked highly for air quality, thanks to its clean-up efforts targeting coal-fired power plants and aged diesel engines. The Burlington-South Burlington-Barre metro area is among the cleanest in the country for air quality, known for its low ozone and short-term particle pollution levels.

North Dakota ranks third for clean air

North Dakota's clean air can be attributed to various factors, including its geographical location and efforts to reduce air pollution. The state has implemented initiatives to improve air quality and protect the health of its residents. For example, North Dakota has a lung cancer screening rate of 10.2%, which is significantly higher than the national average of 4.5%. This increased screening rate has contributed to a 20% reduction in the lung cancer death rate in the state.

Additionally, North Dakota has benefited from federal legislation such as the Clean Air Act, which has driven pollution reduction across the country for over 50 years. The Act is enforced by the U.S. Environmental Protection Agency, which plays a critical role in monitoring and reducing air pollution. However, recent staffing and funding cuts have endangered the agency's ability to continue its important work.

Despite North Dakota's high ranking for clean air, there are still areas for improvement. The report found that North Dakota ranked as the second worst state for radon levels, indicating that there is still work to be done to ensure the state's air quality is consistently among the best in the nation.

Overall, North Dakota's ranking as the third-best state for clean air is a testament to the state's commitment to improving lung health and preventing lung disease. By continuing to prioritize air quality and lung cancer screening, North Dakota can further enhance the respiratory health and well-being of its residents.

Vermont has some of the highest air quality

Air pollution is a serious health threat, with millions of people being especially vulnerable to its effects, including children, older adults, and those with lung diseases. It can trigger asthma attacks, harm lung development in children, and even be deadly. While nearly half of the people in the U.S. live in areas where the air quality is poor, Vermont is an exception, consistently ranking among the states with the cleanest air.

The state has a strong commitment to environmental conservation and has implemented several measures to ensure the air quality remains high. The Department of Environmental Conservation, for example, provides real-time air quality data, allowing residents to make informed decisions about their health. Additionally, the state has a robust monitoring system, with stationary monitoring sites indicated by color-coded boxes on a map, making it easy for residents to check the air quality in their specific locations.

Vermont's clean air can be attributed to a combination of natural advantages and proactive human interventions. The state's low population density, limited heavy industry, and abundant natural landscape all contribute to the lack of air pollution. Additionally, the state has embraced renewable energy sources, such as hydroelectric power, and has implemented strict emissions standards, further reducing air pollutants.

While Vermont is known for its high air quality, the state continues to strive for improvement. The state actively encourages residents to get involved in maintaining and improving air quality, providing resources and tools for monitoring and reducing air pollution. By combining natural advantages with proactive policies and community engagement, Vermont serves as a model for other states aiming to improve their air quality and protect the health and well-being of their residents.

New York has the sixth cleanest air

New York, a state with a huge population of 19.3 million inhabitants, is ranked sixth in the nation for clean air. The state's air quality has improved over the past several decades, with more recent progress being relatively stagnant. The air quality in New York can be attributed to its proximity to other states such as New Jersey, Pennsylvania, Vermont, and Connecticut, as well as its varied industries, including the export of food, electronics, computers, and jewelry.

New York City, the largest city in the state, has a yearly average PM2.5 reading of 6.5 μg/m³, which is impressive given its size and population. The state's air quality index (AQI) has been "good," or below 50, for the last three years of recorded data (2017-2019). This means the air poses little to no risk to health. The World Health Organization (WHO) uses a more stringent threshold for PM2.5 levels than the US EPA, and New York's air quality has consistently fallen within this target since at least 2017, with annual averages of 6.8, 7, and 7 μg/m3 for 2017, 2018, and 2019, respectively.

The main causes of pollution in New York are industrial areas and combustion sources, such as the many vehicles on the road and the use of fossil fuels for energy production. During the COVID-19 lockdown in 2020, New York observed a 25% reduction in fine particle pollution (PM2.5) compared to the same period in 2019. This brief period of improved air quality demonstrated the potential for further emissions reductions through the adoption of electric vehicles and cleaner energy sources.

Overall, New York's air quality is satisfactory, and residents can enjoy outdoor activities without taking special precautions. However, it is always a good idea to stay informed about pollution levels and take preventative measures during periods of higher pollution.

New Hampshire has good air quality

Air pollution is a serious health threat, affecting millions of people, especially children, older adults, and those with lung diseases.
