The Kentucky Center for Investigative Reporting (KyCIR), in collaboration with Side Effects Public Media and NPR’s Appalachia + Mid-South Newsroom, conducted an in-depth analysis of a federal dataset to identify the industrial facilities directly releasing the most greenhouse gases in Kentucky, Indiana, and nearby states. This comprehensive examination primarily focused on emissions tracked by the U.S. Environmental Protection Agency’s (EPA) Greenhouse Gas Reporting Program, which monitors around 7,500 facilities and accounts for about 50% of America’s annual greenhouse gas emissions.
Major Contributors to Greenhouse Gas Emissions
Power Plants: The Dominant Source
A significant portion of greenhouse gas emissions in the Midwest comes from power plants, with over 70% of these plants burning coal to produce electricity. The reliance on coal and natural gas for electricity generation makes power plants the primary contributors to greenhouse gas emissions in the region. These plants alone contribute more than two-thirds of the region’s greenhouse gas emissions, highlighting the need for significant changes in how electricity is generated.
The EPA’s Greenhouse Gas Reporting Program revealed that the top 10 facilities in each state examined together accounted for 14.5% of the facility emissions tracked by the EPA in 2023. This indicates that a relatively small number of facilities have a disproportionately large impact on overall emissions. The prevalence of coal and natural gas in power generation underscores the urgent need for cleaner and more sustainable energy sources to mitigate environmental impact.
Other Industrial Sources
Apart from power plants, other major sources of greenhouse gases in the Midwest include oil refineries, chemical manufacturers, and steel mills. These industries contribute significantly to the region’s emissions due to their energy-intensive processes and reliance on fossil fuels. For instance, oil refineries and steel mills in Northwest Indiana are notable contributors to greenhouse gas emissions. Their operations require substantial energy, often from fossil fuels, leading to significant carbon dioxide releases.
In Northwest Indiana, a local cluster of high-emission facilities, such as U.S. Steel’s Gary Works, Cleveland-Cliffs’ Burns Harbor and Indiana Harbor steel mills, and BP’s Whiting oil refinery, illustrate the concentration of industrial operations contributing significantly to greenhouse gas emissions. These facilities not only affect the environment but also pose environmental justice issues for nearby communities, which primarily comprise working-class and communities of color. The impact on local health and environmental conditions remains a significant concern, exacerbating the challenges posed by industrial emissions.
The Impact of Climate Change
Regional Effects
Climate change, driven by excessive greenhouse gas emissions, poses long-term threats to air, food, and water quality. It contributes to more frequent and perilous extreme weather events, spreads certain infectious diseases, and jeopardizes public health in myriad ways. In the Midwest, observable changes include the eastward shift of Tornado Alley, now increasingly affecting Western Kentucky, along with devastating floods caused by hurricanes in Tennessee and North Carolina.
Tim Darst from the Passionist Earth and Spirit Center in Louisville pointed out these tangible changes as evidence of the immediate and growing impacts of climate change on the Midwest and South. He reiterated that the continuation of burning fossil fuels will exacerbate these impacts, highlighting the urgency of transitioning to cleaner energy sources. The reality of shifting weather patterns and more frequent extreme weather events underscores the need for rapid action to address the root causes of climate change.
Global Perspective
Greenhouse gas emissions are global pollutants, meaning that the carbon dioxide released in one region impacts the global atmosphere just as emissions from other regions do. Daniel Zimmerle, director of Colorado State University’s Methane Emissions Program, emphasized this point, noting that operations emitting substantial amounts of greenhouse gases often overlap with those discharging toxic pollutants that have more immediate detrimental effects on local health and environmental conditions. The interconnectedness of global emissions underscores the collective responsibility to reduce emissions worldwide.
Zimmerle’s insights highlight how local high-emission facilities, while significantly impacting regional environments, also contribute to the broader global challenge of climate change. The detrimental effects on local health, combined with the global impact of greenhouse gas emissions, underscore the necessity for comprehensive and coordinated efforts to mitigate emissions across all sectors and regions.
Efforts to Reduce Emissions
Transitioning to Cleaner Energy
The power sector has demonstrated a marked trend of decreasing emissions, evidenced by a 22% reduction from 2011 to 2023, according to EPA data. This trend extends to the nine states analyzed, which saw a collective 36% drop in emissions from large facilities between 2011 and 2023, with Illinois and Kentucky leading with 48% and 47% reductions, respectively. This reduction is primarily due to the power sector’s shift towards renewable energy, such as solar and wind, driven by competitive pricing.
TVA spokesperson Scott Fiedler explained that their high-emissions facilities reflect their role in providing power to seven Southeastern states. He added that the TVA aims to shut down its remaining coal plants by 2035 and achieve net-zero carbon emissions by 2050 through diversified clean energy investments. Similarly, AEP, which owns six high-emission facilities across West Virginia, Indiana, Ohio, and Oklahoma, expressed its commitment to maintaining reliable energy supply while transitioning to cleaner energy sources.
Challenges in Other Industries
The Kentucky Center for Investigative Reporting (KyCIR), in partnership with Side Effects Public Media and NPR’s Appalachia + Mid-South Newsroom, undertook a detailed analysis of a federal dataset to pinpoint the industrial facilities in Kentucky, Indiana, and surrounding states that are the largest emitters of greenhouse gases. This thorough investigation primarily targeted emissions observed by the U.S. Environmental Protection Agency’s (EPA) Greenhouse Gas Reporting Program. This program scrutinizes approximately 7,500 facilities, indicating they are responsible for about half of the total annual greenhouse gas emissions in the United States.
Such an investigation is crucial because it sheds light on the significant contributors to air pollution and climate change in these regions. By identifying these major polluters, the study provides valuable insights for policymakers, environmentalists, and the general public in striving to mitigate the impact of these emissions. Efforts like these are essential for pushing forward initiatives to reduce greenhouse gas emissions and address climate change’s effects on local and global scales. Understanding the source of these emissions is the first step in devising effective strategies to reduce them.
