The report analyzes the US synthetic nitrogen fertilizer market, which is highly centralized with 71% of capacity held by four producers. It evaluates seven ammonia production pathways, ranging from mature 'blue ammonia' (SMR with CCS) to lab-scale electrochemical and photochemical methods. The document identifies key barriers to green ammonia adoption, including high financing risks, lack of industrial standards, and the absence of long-term offtake agreements from farmers. It highlights state-level incentives in North Dakota, Minnesota, Illinois, New York, and Michigan, alongside federal support via the Inflation Reduction Act's 45V clean hydrogen production tax credit, which offers up to $3/kg of hydrogen.

In 2024, wind and solar produced 17% of US electricity, overtaking coal for the first time as coal fell to 15%. This transition is evident in 24 states, driven by market dynamics, cost-effectiveness, and policy mandates like the Climate and Equitable Jobs Act in Illinois.

The document argues that repealing federal technology-neutral electricity tax credits (§45Y and §48E) would significantly increase household energy bills across the United States. Drawing on analyses from multiple research groups, it estimates that national annual household energy bills would rise by $40–$60 in 2030, $56–$150 in 2035, and $140–$220 by 2040. The report highlights that these credits lower costs by reducing investment expenses for wind, solar, battery, nuclear, and geothermal projects, savings which utilities are regulated to pass on to consumers. Repeal would likely lead to substantial price hikes in specific states, with some households facing increases over $500 annually.

The guide explains how climate change influences spring weather, noting that warmer temperatures increase the frequency of large hail and heavy rainfall, while tornado patterns are shifting in location and timing despite complex overall trends.

RMI outlines five key factors—facility suitability, electricity costs/net metering, energy efficiency, battery sizing, and available funding—to help US communities deploy solar-plus-battery microgrids that serve as resilience hubs during disasters.

The Federal Hydrogen Hub Program aims to establish a national hydrogen network through seven regional hubs, with funding distributed across four phases over 8-12 years. While hubs claim local economic and environmental benefits, the guide notes that many proposed projects may increase pollution or waste energy. As of January 28, 2025, the DOE has instructed all recipients to cease activities related to Community Benefits Plans, pending further guidance.

The document outlines the framework for state Clean Electricity Standards (CES), emphasizing that effective policies must be mandatory, technology-inclusive, and ambitious. It contrasts CES with Renewable Portfolio Standards (RPS) by highlighting the inclusion of clean firm resources like nuclear and carbon capture. The brief details various design options—such as retail sales vs. emission-based standards—and explains how federal incentives from the Inflation Reduction Act (IRA) and Infrastructure Investment and Jobs Act (IIJA) reduce implementation costs. It also discusses advanced features like clean capacity standards and hourly matching to accelerate the deployment of long-duration storage and firm clean power.

The New Flyer Community Benefits Agreement (CBA), signed in 2022 between New Flyer of America Inc., Jobs to Move America (JMA), and Greater Birmingham Ministries (GBM), establishes workforce development and equity standards for bus manufacturing plants in Anniston, Alabama, and Ontario, California. The agreement mandates that 45% of new hires and 20% of promotions come from historically disadvantaged groups, including BIPOC, women, LGBTQ+ persons, and formerly incarcerated individuals. It also establishes pre-apprenticeship and technical training programs, a discrimination complaint system managed by the NAACP in Alabama, and semi-annual safety training. The CBA was the result of a multi-year campaign by JMA and a broad coalition that used legal challenges and research on pay gaps to pressure the company. While the Ontario facility has since closed, the agreement has led to increased hiring of disadvantaged groups and contributed to the successful unionization of the Anniston plant in May 2024.

The document explains that attribution science uses climate models and observational data to compare a world with human-induced warming to a fictional world without greenhouse gas emissions to determine the impact of climate change on specific weather events. It notes that 83% of such studies find a climate link and encourages journalists to explicitly connect these events to fossil fuel use and human vulnerability.

The report argues that shifting from prescriptive 'recipe-based' concrete specifications to performance-based standards (PSS) is essential for scaling low-carbon concrete and meeting climate goals. It identifies key bottlenecks—specifically the lack of a standardized suite of tests for durability and workability—and proposes a collaborative model where project stakeholders (owners, engineers, contractors, and labs) use real-world projects as testbeds to gather data. The document outlines specific roles for each stakeholder, provides case studies from DOTs and private firms, and suggests starting points for testing strength, durability, and workability to build a robust, industry-wide PSS.

The report examines a range of legislative and regulatory efforts to address private equity's role in the US healthcare system, highlighting a shift toward increased oversight of mergers and acquisitions at the state level. It details successful laws in Illinois, Indiana, New Mexico, and New York, while noting failures in states like California and Massachusetts. Federally, it discusses proposed acts to penalize corporate looting and increase transparency, alongside CMS rules on staffing and spending. The document also tracks antitrust and fraud enforcement actions and concludes with policy recommendations to curb financialization through stricter transparency, debt limits, and joint liability.

The report argues that private equity firms prioritize high returns (at least 15%) over short timelines (3-5 years), leading to deferred maintenance and increased tenant instability. It proposes a toolkit of interventions, including rental registries with beneficial ownership disclosure, just cause eviction protections, landlord licensing with portfolio caps, and right of first refusal legislation. The document also examines federal legislative attempts to curb consolidation through tax penalties and transfer taxes, while highlighting the challenge of state preemption of local housing justice measures.

The report argues that the US can significantly reduce its reliance on newly mined minerals for electric vehicle (EV) batteries by prioritizing energy efficiency, right-sizing battery range, and implementing robust recycling policies. Through a 'Very Low Demand Scenario,' the authors demonstrate that newly mined lithium needs could be reduced by 48% from 2025 to 2050, saving 1.5 million metric tons of material. The analysis emphasizes that while electrification is essential for decarbonization, a systems-wide approach—including investments in public transit and rail to reduce vehicle miles traveled (VMT)—is necessary to create a sustainable and just supply chain.

The Union of Concerned Scientists reports that industrial agriculture is the leading cause of wetland loss over the last 250 years, which increases flood risks and releases stored carbon. In the Upper Midwest, 30 million acres of wetlands provide approximately $23 billion in annual residential flood mitigation benefits, with long-term value estimated between $323 billion and $754 billion. The document urges the US government to use the upcoming farm bill to increase funding for USDA conservation programs, such as the Conservation Reserve Program and Wetland Reserve Easements, to protect these ecosystems.

Industrial agriculture is a primary driver of wetland loss in the US Upper Midwest, where 30 million acres of wetlands provide critical flood mitigation and carbon sequestration. The report estimates that these wetlands provide nearly $23 billion in annual residential flood mitigation benefits, with long-term value between $323 billion and $754 billion. Recent legal shifts, specifically the 2023 Supreme Court ruling in Sackett v. EPA, have reduced federal protections under the Clean Water Act, leaving many wetlands vulnerable. The author argues that the next farm bill should expand the Conservation Reserve Program (CRP) cap, increase funding for the Conservation Stewardship Program (CSP) and Environmental Quality Incentives Program (EQIP), and link crop insurance to conservation practices to mitigate flood risk and support environmental justice for marginalized communities.

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).

The Sherco coal plant in Minnesota transitioned to a clean energy hub by replacing retired capacity with 710 MW of solar and a 10 MW/1,000 MWh iron-air battery system. This transition was enabled by Inflation Reduction Act (IRA) incentives, the use of a 'generator replacement' process to bypass interconnection queues, and early community and labor engagement. The project serves as a model for 'clean repowering,' which RMI estimates could deploy 250 GW of clean energy and save ratepayers $12 billion nationwide.

The document explains the science of cumulative impacts, contrasting traditional single-chemical risk assessments with a holistic approach that considers multiple pollution pathways, pollutant accumulation, and non-chemical stressors. It advocates for the precautionary principle and the regulation of chemicals as classes to better protect overburdened communities, while emphasizing that lived experience and qualitative data are essential scientific components for effective policy.

The Community Guide to Cumulative Impacts explains how to identify and quantify the combined effects of multiple pollutants and social stressors on public health. It details existing state and city laws in the US that allow regulators to deny permits based on cumulative impacts and provides a framework for community organizing, including drafting model legislation and using environmental justice mapping tools.

The document examines the prevalence of perfluoroalkyl and polyfluoroalkyl substances (PFAS), known as "forever chemicals," in the U.S. environment and population. It details the health risks, including cancer and immune suppression, and outlines the regulatory response led by the EPA's 2021 Strategic Roadmap and the 2024 National Primary Drinking Water Regulation. The brief also covers state-level phase-outs, legislative efforts in the 118th Congress, and technical challenges in remediating PFAS from water and soil.
