Governor John Bel Edwards has struggled to balance economic interests with environmental concerns, often facing criticism from environmental advocates.

2. California – Smog and Wildfires

Major urban areas like Los Angeles face severe smog issues from vehicle emissions, while wildfires contribute significantly to particulate matter pollution. Governor Gavin Newsom is a strong proponent of environmental policies, pushing for aggressive legislation to combat climate change and reduce emissions from both vehicles and industries.

3. Texas – Oil and Gas Emissions

Texas is heavily impacted by the oil and gas industry, with major companies like ExxonMobil and Valero Energy contributing to air and water pollution.

4. Pennsylvania – Industrial and Coal Pollution

Cities like Pittsburgh are heavily polluted by industrial facilities and coal-fired power plants, including those operated by companies like U.S. Steel. Governor Tom Wolf has worked towards reducing pollution through initiatives like the Regional Greenhouse Gas Initiative, although he faces opposition from powerful industrial and coal lobbies.

5. Indiana – Steel Mills and Coal Plants

The steel industry in Gary and numerous coal-fired plants contribute significantly to Indiana’s pollution, with companies like ArcelorMittal being major culprits. Governor Eric Holcomb has shown interest in transitioning to cleaner energy, but industrial pressures and economic dependencies on these industries present ongoing challenges.

6. Ohio – Manufacturing and Chemical Plants

Ohio’s manufacturing sectors, particularly in cities like Cleveland and Cincinnati, contribute heavily to pollution, with significant emissions from companies like Procter & Gamble and AK Steel. Governor Mike DeWine has initiated measures to improve air quality, but balancing economic interests with environmental health remains a contentious issue.
