The report identifies 19 private equity firms investing in 35 oil and gas companies that have received federal drilling permits since 2017. It estimates that U.S. taxpayers could face up to $384 million in cleanup costs for nearly 2,700 wells operated by these private-equity-backed companies across eight states, with Colorado and New Mexico facing the highest liabilities. The authors argue that the private equity business model—characterized by high leverage and quick exits—combined with outdated federal bonding requirements (averaging only $2,122 per well) and bankruptcy laws, allows firms to externalize environmental costs. The document also highlights 'greenwashing' strategies, such as the promotion of 'certified gas,' used to maintain investor support despite ongoing fossil fuel expansion.

Climate Central reports that 97% of 240 analyzed U.S. locations saw an increase in annual cooling degree days (CDD) between 1970 and 2022, with the most significant rises in the Southwest, South, and Southeast. Projections suggest U.S. household cooling demand will increase by 71% by 2050, while global demand is expected to more than triple. The document highlights that rising demand can strain power grids, increase greenhouse gas emissions from fossil fuels and HFCs, and exacerbate urban heat islands. It also notes a disproportionate energy burden on low-income and minority households, who may delay cooling use due to cost. Proposed solutions include transitioning to renewable energy, adopting high-efficiency heat pumps, and implementing building retrofits.

The briefing argues that insufficient transmission capacity is a major bottleneck for US decarbonization, with new capacity seeking interconnection consisting of 95 percent zero-carbon resources in 2022. It identifies grid-enhancing technologies (GETs) as cost-effective, rapid-deployment solutions that optimize existing transmission, but notes that utility adoption is hindered by risk aversion and regulatory incentives that reward capital expenditures over operational efficiencies. To overcome this, the document outlines four strategies for Public Utility Commissions (PUCs): building knowledge through investigative proceedings, mandating the consideration of GETs in planning processes, implementing performance incentive mechanisms or totex ratemaking, and engaging in Federal Energy Regulatory Commission (FERC) proceedings.

A Climate Central analysis of 239 contiguous U.S. locations from 1979 to 2022 shows that 201 locations experienced an increase in annual days with a heat index of 90°F or higher, averaging 10 additional days. The most significant increases occurred in the South, Southeast, Northwest, and Southwest, with McAllen, Texas, seeing the highest increase of 32 more days. The report emphasizes that high humidity multiplies heat risks by limiting the body's ability to cool through sweating, leading to preventable but serious illnesses like heat exhaustion and heat stroke, which disproportionately affect vulnerable populations including children, seniors, and low-income communities.

Industrial thermal batteries can convert electricity into high-temperature heat (1,500-1,700°C), potentially displacing 75% of U.S. industrial non-feedstock energy demand. The report analyzes two primary deployment modes: 'generation-following' (off-grid renewables) and 'price-hunting' (grid-connected, price-responsive). It finds that these batteries can provide heat at $35 to $62 per MWh, making them competitive with natural gas. The authors recommend financial incentives via the Inflation Reduction Act and reforms to electricity tariffs to reward the grid flexibility these batteries provide.

The report details how Pipeline Health, backed by firms including Stanton Road Capital, Davidson Kempner Capital Management, and Deerfield Management, utilized sale-leaseback transactions and complex subsidiary structures to monetize hospital real estate. It highlights the closure of Westlake Hospital in Illinois, which occurred despite promises to regulators, and the sale of Weiss Memorial Hospital's parking lot for luxury housing. The document concludes that these practices led to Pipeline's own Chapter 11 bankruptcy in 2022 and recommends stricter state and federal oversight of private equity acquisitions of safety net hospitals.

The report details how Pipeline Health utilized sale-leaseback transactions to monetize hospital real estate and employed a complex web of subsidiaries to obscure ownership. It specifically highlights the closure of Westlake Hospital in Illinois, which the report claims was planned prior to acquisition despite assurances to regulators, and the sale of Weiss Memorial Hospital's parking lot for luxury housing development.

The Transit to Trails Act aims to provide grants to underserved communities to create mobility to public lands, waters, and parks. The author asserts that this legislation is critical because communities of color are three times more likely than white communities to live in nature-deprived places. The document highlights significant underrepresentation of Black, Hispanic, Asian-American, and Native American populations in national parks, often due to transportation barriers. It specifically notes that urban Latino Americans are twice as likely to rely on public transit than urban White Americans, and that 69% of Bay Area Latinos lack access to a personal vehicle. The act is presented as a means to improve public health, air quality, and environmental liberation.

This report by the Union of Concerned Scientists highlights the challenges and successes of frontline communities in the US and Puerto Rico in building climate resilience. It identifies four key themes: displacement, government negligence, funding inequities, and the effectiveness of community-driven solutions. The authors argue that while scientific solutions exist, a lack of political will and bureaucratic barriers hinder progress. The report provides specific recommendations to shift toward inclusive, community-led adaptation strategies that respect tribal sovereignty and prioritize the lived experiences of marginalized populations.

The report examines how 'heirs' property'—land passed down without clear legal titles—contributes to the systemic loss of Black-owned farmland in the US. It highlights that Black farmers lost nearly 90% of their land during the 20th century, with heirs' property acting as a primary driver of involuntary land loss through forced partition sales and limited access to federal funding. The document argues that the USDA and Congress must provide direct grants, streamline farm number establishment, and fund community-based legal services to resolve clouded titles and support BIPOC farmers.

Austin ISD passed a resolution in September 2022 committing to purchase exclusively electric school buses by 2030 and achieve full fleet electrification by 2035. This transition is aligned with the city of Austin's goal of net-zero community-wide emissions by 2040 and is supported by a $2.4 billion 2022 Bond, which allocated $25.7 million for bus replacement. The district is initiating the transition with a pilot of three electric buses arriving in fall 2023 to test performance across various routes. Key challenges include the higher initial cost of electric buses, which are three to four times more expensive than diesel models, leading to potential funding gaps in initial bond estimates.

The Union of Concerned Scientists (UCS) published this guide to help the public influence the EPA's proposed rule on ethylene oxide (EtO) emissions from commercial sterilizers. The guide argues that while the proposal is a positive step—potentially reducing emissions by 80%—it contains significant gaps regarding cumulative health risks, fenceline monitoring, and the regulation of off-site warehouses. It urges commenters to support the use of the 2016 IRIS risk assessment, demand continuous emissions monitoring systems (CEMS), and call for a faster compliance timeline than the proposed 18 months. The document also highlights environmental justice concerns, noting that people of color and low-income communities are disproportionately located near these facilities.

Climate Central analyzed 247 U.S. locations from 1970 to 2022, finding that 232 locations experienced an increase in annual 'risky heat days'—days where temperatures exceed the local minimum mortality temperature (MMT). On average, these locations saw an increase of 21 such days per year. While increases occurred in every U.S. region, the South and Southeast were hotspots, with 91% of the 22 locations seeing the highest increases (40+ days) located there. The analysis emphasizes that extreme heat is the deadliest natural hazard in the U.S. and disproportionately affects vulnerable populations, including children, seniors, and low-income communities of color.

RMI organized Solarize cohorts in 2021 and 2022 involving 27 U.S. cities to make rooftop solar more accessible to low- and moderate-income (LMI) communities. By combining bulk purchasing discounts with grants and community partnerships, the program helped nearly 1,200 households install over 10 MW of residential solar, with 40% of participants from LMI or BIPOC communities. These installations are projected to save households over $8 million and avoid 106,000 tons of CO2 emissions over 25 years.

Using the EPA's AVERT tool and 2021 data, the analysis finds that ignoring additionality, regionality, line loss accounting, or hourly time-matching can lead to hydrogen production emissions that exceed the threshold for the top $3/kg 45V tax credit. Specifically, forgoing additionality could result in emissions 22 to 40 kgCO2/kgH2, which is more than twice the emissions of steam methane reformation.

RMI analysis finds that utility-scale solar and onshore wind are already cheaper to build than new natural gas plants in Texas, even without the Chapter 313 tax incentives. The report argues that excluding renewables from the next iteration of Chapter 313 via House Bill (HB) 5 is economically inefficient, as it would require $150 to $300 in taxpayer funds per kilowatt to make natural gas competitive. Furthermore, rapid adoption of clean technologies could allow Texas to retain $130 billion in-state through federal tax credits, with approximately 35 percent of that amount stimulating the electricity sector.

The Center for International Environmental Law (CIEL) presents a critical overview of Carbon Capture and Storage (CCS), asserting that the technology overpromises on emission reductions while introducing significant safety risks and high costs. The document highlights the 'energy penalty'—the extra energy required to power capture equipment—and notes that most existing projects are used for enhanced oil recovery (EOR), which can increase overall emissions. It warns that a large-scale CCS buildout in the United States would require an unrealistic and dangerous expansion of pipeline infrastructure. Furthermore, the text argues that CCS is unnecessary for 'hard to abate' industrial sectors, where electrification and demand reduction are more viable, and critiques 'blue hydrogen' as a means to prolong fossil fuel dependence. The document concludes that global capture capacity is negligible compared to total emissions and that public subsidies, such as the US 45Q tax credit, inappropriately support the fossil fuel economy.

The report examines the implementation of the Section 45V hydrogen production tax credit from the Inflation Reduction Act. It argues that loose guidance on emissions accounting could lead to significant increases in greenhouse gas emissions and create an industry reliant on subsidies. The authors propose a framework based on three principles: additionality (requiring new clean energy sources), deliverability (requiring local, physically deliverable power), and time-matching (requiring hourly alignment of production and generation). Financial analysis of test sites in Texas, Minnesota, and Houston suggests that projects adhering to these strict standards remain profitable, particularly in regions with high wind and solar resource quality.

The report finds that The Carlyle Group invested in 91 energy companies owning 972 assets between 2011 and 2021, with 90% of these being fossil fuel investments. These assets emitted an estimated 277 million metric tons of CO2e, with emissions growing at an average annual rate of 95%. The analysis highlights a significant disparity between Carlyle's fossil fuel investments ($22.4 billion) and its renewable energy commitments ($1.4 billion). Furthermore, the report documents that 84% of Carlyle's downstream US assets are located in areas with higher concentrations of low-income residents or people of color than state averages, and 47% of these plants have a record of environmental violations.

The report finds that The Carlyle Group invested in 91 energy companies owning 972 assets from 2011 to 2021, with 90 percent of both companies and assets being fossil fuel investments. These investments emitted an estimated 277 million metric tons of CO2e, with a compound annual growth rate of 95 percent. The analysis highlights a significant disparity between Carlyle's fossil fuel capacity (peaking at nearly 10,000 MW in 2021) and its renewable capacity (just over 1,300 MW). Furthermore, the report documents that 84 percent of Carlyle's current US downstream fossil fuel assets are located in areas with higher percentages of low-income residents and/or residents of color than state averages, and 47 percent of these plants have a record of environmental violations.
