What You'll Learn
Vehicle, industrial and chemical emissions
Kansas City has experienced unusually poor air quality in 2024, with high levels of smog. This is due to a combination of factors, including vehicle emissions, industrial emissions, and chemical emissions.
Vehicle emissions are a significant contributor to air pollution in Kansas City. Gas-powered cars, in particular, release fumes and burn fuel, which leads to ground-level ozone formation. In addition to cars, domestic engines like lawnmowers and leaf blowers contribute to air pollution. To reduce vehicle emissions, residents are encouraged to drive less, opt for public transportation or carpooling, or choose walking or cycling for shorter distances.
Industrial emissions also play a role in Kansas City's air pollution. Facilities that produce over 25,000 metric tons of CO2e annually are mandated to report their emissions to the EPA. Power plants, such as the Iatan Generating Station, are among the largest producers of nitrogen dioxide (NO2), a significant contributor to smog. Industrial activities that release hydrocarbons into the atmosphere further exacerbate air quality issues.
Chemical emissions are another factor influencing Kansas City's air quality. Volatile organic compounds (VOCs) are released during activities like mowing the lawn and using VOC paints or other chemicals for home improvements. These compounds contribute to the formation of ground-level ozone, which can reach unhealthy levels.
While Kansas City has made progress in reducing particle pollution from sources like coal-fired power plants and old diesel engines, the combination of vehicle, industrial, and chemical emissions continues to impact the city's air quality, particularly during the summer ozone season, which lasts from April 1st to October 31st.

Nitrogen oxide emissions
Kansas City, the largest city in Missouri by population and area, has been facing issues with poor air quality. While the city's air quality was rated as "Good" in December 2022, with a US AQI reading of 31, it has witnessed a decline in 2024. The primary cause of this deterioration is the increase in ground-level ozone, which is formed by gases like nitrogen oxides (NOx) and volatile organic compounds (VOCs) reacting with sunlight.
Nitrogen oxides (NOx) are a family of gases that include nitrous oxide (N2O), nitric oxide (NO), and nitrogen dioxide (NO2). These gases are harmful to human health and contribute to the formation of smog, commonly known as ground-level ozone. In 2024, Kansas City experienced higher than usual levels of ground-level ozone, which led to an increase in smog days and ozone alerts. This was attributed to a combination of weather conditions and emissions from vehicles, industrial activities, and power generation within the metropolitan area.
The U.S. Environmental Protection Agency (EPA) has recognized the impact of Missouri's emissions on neighbouring states and has taken steps to address this issue. The EPA's Good Neighbor Rule and Good Neighbor Plan aim to reduce nitrogen oxide emissions from power plants and industrial facilities in Missouri and 22 other states. These regulations specifically target NOx emissions, which are a significant contributor to ground-level ozone and smog. By 2027, Missouri's power plants must reduce their nitrogen oxide emissions by 11,230 tons.
While Kansas City's air quality issues are concerning, there are positive signs of improvement. Major utility providers in the city, such as Evergy and Spire, have made significant progress in reducing their NOx emissions. Evergy, in particular, reported an 88% reduction in NOx emissions company-wide and in Missouri since 2005. This reduction is attributed to the implementation of emission reduction technology at their coal power plants. Additionally, year-round particle pollution levels in Kansas City have decreased due to the clean-up of coal-fired power plants and the retirement of old, dirty diesel engines.
To further improve air quality and reduce nitrogen oxide emissions, individual actions can also make a difference. Residents can reduce their contribution to ozone pollution by postponing or reducing certain activities, especially during Ozone Air Days. This includes driving less, opting for public transportation or carpooling, and choosing walking or cycling for shorter distances. Additionally, rescheduling strenuous outdoor activities and limiting the use of domestic engines, such as lawnmowers and leaf blowers, can help lower emissions and improve air quality in Kansas City.

Particle pollution
Kansas City has experienced periods of poor air quality, with ground-level ozone forming during the summer months. While ozone is a significant concern, particle pollution remains a year-round issue. The clean-up of coal-fired power plants and the retirement of old diesel engines have contributed to a decrease in particle pollution levels. However, other sources, such as vehicle exhaust, power generation, industrial emissions, and volatile chemicals, continue to impact the city's air quality.
According to the Air Quality Index (AQI), Kansas City's air quality was rated as “Good” during Christmas 2022, with a US AQI reading of 31. The main pollutant was PM2.5, recorded at 4.8 µg/m³, which is within the recommended target of 5 µg/m³ suggested by the World Health Organization (WHO). This improvement is a positive sign, indicating that efforts to reduce particle pollution are showing progress.
To address particle pollution, it is crucial to reduce emissions from various sources. This includes regulating vehicle emissions, improving industrial processes to minimize pollutant release, and promoting the use of cleaner energy sources. Individual actions, such as reducing personal vehicle usage, opting for energy-efficient appliances, and minimizing the use of wood-burning devices, can also contribute to lowering particle pollution levels.
Additionally, monitoring and forecasting systems, such as Skycast, play a vital role in managing particle pollution. Skycast utilizes a colour-coded system to indicate daily pollution levels, helping residents make informed decisions to protect their health. By staying informed about particle pollution levels and taking appropriate actions, Kansas City residents can actively contribute to improving the air quality in their community.

Pollution from highways, railways and industry
Kansas City, Missouri, has been experiencing unusually poor air quality in 2024, with high levels of smog and ozone pollution. While some of this can be attributed to wildfires in Canada, a local air quality expert claims that the majority of the pollution is produced within the city itself.
Highways and Roads
Vehicle exhaust fumes are a significant contributor to air pollution in Kansas City. The city is surrounded by major highways and roads, which see a lot of diesel truck traffic. In addition, it is common for people to leave their cars idling in winter to defrost or warm up before their daily commute.
Railways
Kansas City is home to the second-largest rail hub in the United States. The exhaust from diesel locomotives contains particles such as nitrogen oxides and black carbon, which are known to cause severe respiratory issues, lung cancer, heart disease, and neurological disorders. Regulatory loopholes allow the railroad industry to avoid adhering to federal locomotive emission standards, and trains that meet the most recent standards make up less than 10% of locomotives in service.
Industry
Industrial facilities and power plants are a major source of air pollution in Kansas City, releasing harmful chemicals and fumes into the atmosphere. These emissions include nitrogen oxide, which contributes to smog, and volatile organic compounds (VOCs), which are released from activities such as painting or using chemicals. While emissions of nitrogen oxide have decreased by 88% since 2005, according to a company spokesperson, the city still experiences high levels of smog and poor air quality.

Pollution from burning in the Flint Hills
The Flint Hills, spanning from northern Kansas into Oklahoma, are a tallgrass prairie ecosystem that has been forged by fire. Native Americans routinely burned the prairie to attract bison, and wildfires also naturally occurred through lightning strikes. As a result, a lush but delicate ecosystem of grasses emerged, becoming dependent on fire to sustain a treeless ecosystem.
Prescribed burning is a common tool for land management in the Flint Hills region. However, the widespread synchronized pasture burning in late spring has become a societal issue due to the exceedance of air quality thresholds. The production of large amounts of smoke from en masse late-spring burning facilitates the formation of ground-level ozone, often exceeding US Environmental Protection Agency (EPA) standards. Airborne chemical and particulate pollutants created from burning can increase the incidence of asthma, cardiovascular problems, lung cancer, and acute bronchitis.
To address the issue of smoke pollution, potential mechanisms include regulating the amount of burning on a particular day, burning less frequently, or burning earlier in the spring to distribute smoke production over a longer time period when ozone is less likely to be formed. However, bureaucratic intervention may not be feasible for regional grassland stewardship.
Researchers have also proposed expanding the "burn window" into late summer and early fall to better manage invasive species and reduce the impact of smoke emissions on public health. Studies have shown that burning during this period can still provide the same agricultural benefits as burning in April. A longer prescribed burning period would allow land managers to meet their goals while decreasing the short-term elevated pollution impacts due to smoke.
