Ohio is experiencing an increase in the frequency and severity of extreme precipitation, flooding, heat, and drought, with natural disaster costs reaching $2 to $5 billion in the first half of 2026. These hazards are compounded by aging infrastructure, including high-hazard dams and levees, and a legacy of industrial pollution from Superfund sites. The state's energy grid is under strain from extreme heat and surging demand from over 200 data centers, while state policy continues to favor fossil fuels and obstruct renewable energy development. Key military assets, such as Wright-Patterson Air Force Base, face significant flood and wildfire risks. While Ohio lacks a comprehensive statewide climate governance framework, some progress has been made through municipal adaptation plans and significant support from federal agencies like NOAA, FEMA, and the EPA.

The document outlines a comprehensive framework for local governments to scale the deployment of air-source and ground-source heat pumps and heat pump water heaters. It details a five-step methodology: building a diverse program team and setting goals, engaging and qualifying local contractors, designing affordable incentive and financing structures, executing community outreach, and managing program launch and impact tracking. The guide emphasizes equity, specifically targeting low-to-moderate income (LMI) and frontline communities, and leverages federal incentives from the Inflation Reduction Act (IRA) and Infrastructure Investment and Jobs Act (IIJA).

Climate Central analyzed the urban heat island (UHI) index across 65 major U.S. cities, finding that 68% of the 50 million residents in these cities live in areas where the built environment increases temperatures by 8°F or more. The study identifies albedo, green space, and population density as the primary drivers of this effect. It also highlights a link between historical redlining and current heat disparities, noting that in 84% of 179 analyzed cities, historically redlined areas experience hotter summers than non-redlined areas.

The Episcopal Southern Ohio Diocese established the Energy Efficiency Grant and Loan Program in July 2021 to fund energy-saving retrofits in its congregations. The program requires participants to conduct ASHRAE Level 2 energy audits and develop reduction plans to qualify for grants of up to $10,000 or low-interest loans of up to $10,000. By June 2023, the program awarded $533,047 through 56 grants and disbursed $121,207 in loans. Case studies of churches in Athens, Circleville, and Washington Court House demonstrate the adoption of LED lighting, high-efficiency furnaces, and ductless mini-split heat pumps to lower carbon emissions and operational costs. The document also notes that the Inflation Reduction Act's "direct pay" incentives may now encourage these nonprofits to pursue solar installations after first improving building efficiency.

The Great Lakes region is positioned for an industrial renaissance in clean energy, having seen over $40 billion in new investments since 2021. However, the report argues that the region faces significant constraints, including slow population growth, a migration of manufacturing to the US South, and uneven clean electricity deployment. To overcome these, RMI suggests that states prioritize industries where they have existing 'economic complexity' and related capabilities, such as EV batteries and low-carbon steel. The report highlights the importance of coordinating across state lines to share legislative best practices—such as the creation of green banks and competitiveness funds—and recommends a regional investment attraction strategy to draw foreign direct investment. It specifically praises Illinois and Minnesota as leaders in environmental justice and workforce development frameworks.

RMI developed the Local Energy Action Framework (LEAF) to help US local governments move from setting carbon-neutrality goals to implementing efficient energy projects. By analyzing six US cities and counties, the framework emphasizes a holistic approach that considers the interaction between energy efficiency, electrification, and renewable procurement. Key findings suggest that prioritizing high-demand facilities like water treatment plants for efficiency and using flexible loads or batteries to manage peak demand are critical for achieving 24/7 clean electricity. The guide also highlights that while electrification significantly reduces emissions, it increases building loads, necessitating the use of efficient technologies like heat pumps and the procurement of off-site non-solar renewable energy to fill remaining gaps.

The brief highlights specific initiatives at ports in California, Georgia, and Florida, while noting the importance of federal resources like the EPA Ports Initiative in supporting these transitions.

Cincinnati is developing a local electric transportation ecosystem involving the manufacturing of electric step vans by Workhorse and their adoption by Servall Electric. Servall is transitioning its fleet of 25 to 30 vehicles to electric and participating in the Run on Less – Electric (RoL-e) demonstration. The transition has resulted in a 75 percent reduction in daily fuel costs, dropping from approximately $60 for gas to $15 for electricity. Beyond financial savings, the electric trucks offer driver benefits such as 'one pedal driving' via regenerative braking and a lower vehicle architecture that reduces physical strain on drivers. The document also notes that urban last-mile delivery emissions in the top 100 global cities could increase by over 30 percent by 2030, reaching 25 million tons of CO2 annually.

The briefing outlines six funding models—sales taxes, retail taxes, fossil fuel production taxes, electricity consumption taxes, climate bonds, and resilience bonds—that US cities have implemented to fund climate action. It highlights specific examples from cities like Denver, Portland, and Miami, emphasizing that integrating equity into the design of these funding streams is essential for success, particularly for Black, Indigenous, Latino, and low-income communities who are disproportionately affected by pollution and climate change.

The authors advocate for a city-led approach to US infrastructure recovery, calling for federal partnerships, the redirection of transportation funding toward public transit and active travel, and the reform of energy markets to remove barriers to renewable energy procurement.

The Food Waste Warriors project analyzed plate waste in 46 US schools, finding that students waste an average of 39.2 pounds of food and 28.7 cartons of milk per year. The study highlights the significant environmental and financial costs of this waste, estimating a national impact of 530,000 tons of food waste and 45 million gallons of milk waste annually. Results indicate that simple interventions and awareness can reduce waste, with elementary schools seeing a 14.5% reduction. The report recommends policy reforms to National School Lunch Program (NSLP) portion sizes and the adoption of bulk milk dispensers to mitigate these losses.

The document details how climate change is increasing the frequency and severity of heat waves in the United States, leading to higher mortality rates and significant disruptions. It highlights the disproportionate vulnerability of children, the elderly, low-income and minority populations, and outdoor workers. Beyond health, extreme heat damages transportation infrastructure, reduces agricultural yields, and strains the electricity grid, necessitating a transition to low-carbon energy solutions and adaptive urban design to mitigate these risks.

The Union of Concerned Scientists reports that the EPA's January 25, 2018, withdrawal of the "once in, always in" (OIAI) policy allows industrial facilities to be reclassified from "major sources" to "area sources" of hazardous air pollutants (HAPs). This reclassification removes the requirement for facilities to use Maximum Achievable Control Technology (MACT), which the authors estimate was used by 70 percent of major sources in 2014 to keep emissions at or below thresholds of 10 or 25 tons per year. The document warns that area sources are not regulated or inspected as stringently, potentially increasing emissions of toxic substances like chlorine, benzene, and styrene. The analysis identifies at least 21 states at risk of increased pollution, with specific high-risk clusters in Louisiana's "Cancer Alley," Houston, Chicago, and the New York-Newark urban area.

The document details how oil and gas emissions, including ozone smog from across the central and western US and local toxic pollutants, cause significant health issues in Ohio. It highlights that nearly 30,000 children in Ohio suffer annual asthma attacks due to industry-linked ozone, with high concentrations in the Cleveland-Akron, Columbus, and Cincinnati areas. Additionally, it notes that over 160 tons of hazardous toxic air pollutants were emitted from more than 90,000 sites in Ohio in 2011, and over 2,500 schools are located within a half-mile of these operations.

The Measuring Up 2015 report analyzes climate action across 116 US local governments, representing approximately 14% of the US population. It finds that achieving these cities' 2050 emissions goals would be equivalent to shutting down 86 coal-fired power plants. The report highlights the success of cities like Atlanta, Cincinnati, Minneapolis, and Portland, noting that strong government leadership, supportive state policies, and private sector partnerships are critical for success. It argues that while local actions are significant, they require an enabling national policy framework, including strong power plant regulations and carbon pricing, to reach their full potential.

The report details how Illinois municipalities use Community Choice Aggregation (CCA) to pool electricity purchasing power, enabling them to negotiate lower rates and switch to cleaner energy sources. Since 2013, over 90 Illinois towns have transitioned to 100% renewable electricity via Renewable Energy Credits (RECs), increasing demand for wind and solar by over 6 terawatt hours. The document provides case studies from Oak Park and Chicago, analyzes CCA adoption in other states like California and Massachusetts, and offers strategic recommendations for municipalities to move beyond RECs toward local renewable energy investments.

The report details a multi-stakeholder forum focused on transitioning West Virginia from a coal-dependent economy to a diversified one. It identifies key assets such as natural gas, tourism, and a strong workforce, while highlighting the need for state-level leadership and policies like the proposed West Virginia Future Fund. The document emphasizes the role of innovation, STEM education, and energy efficiency in creating sustainable, high-quality jobs.

The report finds that the US Midwest has experienced a significant increase in dangerously hot and humid summer days since the 1940s and 1950s. This trend increases the risk of heat-related illnesses and deaths, particularly for vulnerable populations such as the elderly, children, and urban residents. The analysis, covering 10 cities across eight states, indicates that rising nighttime temperatures and more frequent heat waves exacerbate health risks. Projections suggest that without significant carbon emission reductions, the region will face a substantial increase in days exceeding 90°F and 100°F by the end of the century.

The report finds that the U.S. Midwest has experienced a significant increase in dangerously hot, humid, and dry summer days, as well as more frequent heat waves, over the last 60 years. Analysis of ten cities indicates that nighttime temperatures and humidity are rising, reducing the relief typically found overnight. These trends are linked to higher risks of hyperthermia and dehydration, particularly for vulnerable populations such as the elderly and low-income urban residents. The document argues for a combination of local adaptation strategies, such as heat-response plans and cooling centers, and aggressive global action to reduce fossil fuel emissions to mitigate future extreme heat events.
