Cities like Wilmington, North Carolina, and Pleasanton, California, rank among the least dirty cities, due to their low levels of air pollutants, efficient management of waste and efforts to restrict emissions. Although the city may not have severe issues with near-roadway pollution, residents overwhelmingly find the city dirty and rank it poorly for resident satisfaction. The city ties for the worst median air quality, with an Air Quality Index (AQI) value of 80 and 21.6 percent of residents exposed to near-roadway pollution. So, which cities have it worst? With the worst median air quality in the country – often exceeding limits set by the Environmental Protection Agency (EPA) – the city’s polluted air and greenhouse gas emissions make life tough for residents. With the highest greenhouse gas emissions per capita (it ranks No. 1), Baytown is home to several large refineries that contribute to unhealthy air quality. And greenhouse gas emissions per capita are notably high (8.4 metric tons), placing Trenton No. 14 in pollution ranking and making air quality a persistent issue for the city.
The city also ranks 122nd for waste management, making it a trash heap waiting for improvement. The city’s poor waste management and unhealthy air quality further compound all of these issues. Frequent drinking water violations and inadequate waste management practices contribute to these concerns. Additionally, drinking water contaminants and a high number of overcrowded homes contribute to poor living conditions in San Bernardino. As of June 24, 2024, San Bernardino claims the top spot on the list of the United States’ dirtiest cities. Reading ranks third, largely due to its sky-high greenhouse gas emissions per capita (18.5 metric tons) and being one of the top cities with residents dissatisfied with their city’s overall cleanliness. But on the other, the long history of platforms demonstrates conclusively that if you’re operating an application or service on top of someone else’s platform, and your app or service becomes popular enough, the platform will attempt to replicate or absorb your app or service. Even if the current rate of warming doesn’t speed up, there will still be significant changes in seasons in the future. Despite efforts to restrict emissions, Baytown still ranks poorly in air quality and resident dissatisfaction, placing it No. 107 in the latter category.
The study ranked over 300 cities based on their pollution, waste management, living conditions and resident dissatisfaction levels. The city struggles with pollution, ranking No. 20 overall, and wildfire smoke from nearby regions exacerbates its noxious air. But Ontario’s issues extend beyond air pollution: It ranks poorly in resident satisfaction, with 60.7 percent of residents dissatisfied with the city’s handling of pollution. The city struggles with air pollution and a poor track record for drinking water violations, contributing to resident dissatisfaction, which ranks No. 50 overall. Duluth, Minnesota, and Lynchburg, Virginia, also exemplify how cleaner air, lower greenhouse gas emissions and minimal drinking water violations can create healthier living environments. These policies aim to curb greenhouse emissions and improve the quality of the air over time, though the city’s heavy industrial activity has limited their impact. The influx of tourists also adds to the burden on local waste facilities, and the city ranks No. 110 for living conditions.8 percent of residents express dissatisfaction with how the city handles its water quality and pollution, contributing to its poor ranking in resident dissatisfaction levels (No. 53 overall). Despite being located near cleaner cities like Jersey City, Newark struggles with meeting air quality standards and ranks No. 4 in terms of resident dissatisfaction, with 88.9 percent of residents reporting that they find the city dirty.
These cities enjoy higher resident satisfaction and face fewer health consequences (such as asthma and other respiratory issues), thanks to lower levels of pollution near roadways and compliance with EPA safety guidelines. Reading also suffers from high polluted air levels and challenges with waste management, such as high levels of landfill waste and inadequate recycling infrastructure. Newark lands at number four, primarily due to its high levels of air pollution and ranking No. 1 in annual excess fuel consumption per auto commuter, with 23 gallons (87 liters) wasted per driver each year. Shorter, warmer spring and autumn seasons have become the new norm due to these shifts in season timing and temperature patterns. Las Vegas faces heavy air pollution, ranking No. 31 in pollution, largely due to vehicle emissions and nearby oil refineries. Located in California’s Inland Empire, the city faces heavy pollution from its freight corridor which sees thousands of diesel-fueled commercial trucks passing through on a daily basis. Baytown, Texas, is a small city with big pollution problems.
