Community Access to Clean Air Decisionmaking
The report finds that while most US states meet the minimum legal requirements for Title V air permitting notices, there are substantial gaps in transparency, accessibility, and the actual influence of public input on final decisions. It highlights that many public notices are written at a college reading level and lack plain language, and that few agencies transparently report how public comments shape permit outcomes. The analysis suggests that states with specific environmental justice or cumulative impacts laws tend to have better engagement practices. It recommends that agencies adopt plain language, provide multilingual resources, and establish clear mechanisms for reporting how community input affects regulatory decisions.

LET THE SUN IN: CLEAN ENERGY IS THE CHEAPEST WAY TO MEET RISING DEMAND
The report compares two pathways for meeting U.S. electricity demand growth through 2030: one relying on fossil fuels and another on clean energy. It finds that a clean energy scenario reduces the incremental cost of meeting demand by $5.1 billion annually in 2030 and offers greater protection against fuel price volatility. To realize these savings, the authors recommend setting ambitious clean energy targets, updating electricity system planning with market-based assumptions, reducing permitting and interconnection barriers, implementing fuel cost sharing to manage risk, improving grid utilization through technologies like surplus interconnection and high-performance conductors, and harnessing demand-side resources such as virtual power plants and distributed energy technologies.

Designed to Fail
The report argues that low-density urban sprawl is fiscally unsustainable for Canadian municipalities, contributing to a national infrastructure deficit of CAD 270 billion. Using Winnipeg as a primary case study, it demonstrates how the failure to account for long-term maintenance and carbon costs in development decisions creates a 'municipal Ponzi scheme' where new growth is used to mask the liabilities of old infrastructure. The author recommends reforming development cost charges, property taxes, and fiscal impact assessments to prioritize compact, complete communities that generate more revenue and produce fewer emissions.

Five policies to lower heating bills and accelerate heat pump adoption in Illinois
RMI proposes five policies to accelerate heat pump adoption in Illinois: increasing incentives for heat pumps and weatherization while phasing out gas equipment subsidies, providing 0% financing, reforming electric and gas rate designs, implementing an AC-to-heat pump replacement policy, and adopting electric-friendly standards for new construction. The brief notes that while heat pumps can reduce energy bills for most Illinois households—particularly those using propane or electric resistance heat—high up-front costs remain a primary barrier.

Ending Wasted Food in K–12 Schools
WWF's Food Waste Warriors (FWW) program aims to eliminate food waste in US K–12 schools, noting that nearly 40% of food served in schools is wasted, totaling 530,000 tons and $1.7 billion in lost value annually. The program focuses on three pillars: engaging students through standards-aligned education, expanding edible food recovery via share tables and refrigerators, and diverting waste from landfills through composting. FWW reports that up to 90% of school food waste can be recovered or recycled, with some participating schools achieving a 70% reduction in waste. The report details success stories from Maryland, Maine, Tennessee, and Georgia, and proposes a national data-collection platform and recognition program to scale these efforts.

Neonicotinoid Seed Treatments in North American Row Crops: A Literature Review of Yield and Profitability Outcomes
The review finds that neonicotinoid seed treatments (NSTs) often fail to provide statistically significant increases in yield or profitability for North American farmers, particularly in colder regions like the Midwest and Northern U.S. where early-season pest pressure is lower. While some positive returns on investment (ROI) were observed in the U.S. South due to milder winters and higher pest pressure, these results were inconsistent year-to-year. The document highlights significant ecological harms, including the reduction of predator insect populations, damage to pollinators, and disruption of soil decomposition. It argues that a shift from prophylactic use to an 'assess-and-decide' approach based on actual pest pressure would save farmers money without reducing yields.

Understanding the Value of the Greenhouse Gas Reporting Program, and the Impacts of EPA’s Proposal to Roll Back the GHGRP
The EPA has proposed a significant rollback of the Greenhouse Gas Reporting Program (GHGRP), which would remove reporting requirements for 46 of 47 source categories and suspend subpart W reporting until 2034. This proposal threatens the viability of over 270 carbon capture projects and $77.5 billion in capital investment because the 45Q tax credit relies on GHGRP for monitoring, reporting, and verification (MRV). Specifically, the loss of subparts PP, RR, and VV would prevent carbon capture and storage (CCS) and enhanced oil recovery (EOR) projects from claiming 45Q credits. For hydrogen projects, the delay of subpart W would reduce the reliability of upstream methane leak rate measurements used in the 45VH2-GREET tool for 45V tax credits, potentially forcing taxpayers to rely on an inaccurate 0.9% national average and increasing legal risks for high performers. Internationally, the rollback could disadvantage U.S. exporters in markets requiring verified data, such as those under the EU Carbon Border Adjustment Mechanism (CBAM). Domestically, at least ten states, including California and Colorado, have embedded GHGRP into their legal frameworks; removing it would force these states to create costly patchwork substitutes to maintain emissions inventories.

DODGING THE FIRM FIXATION FOR DATA CENTERS AND THE GRID
The report critiques the 'firm fixation' approach where utilities meet surging data center demand by adding gas plants or refurbishing coal units. It identifies six defining features of data centers—agency, clustering, consumption profiles, flexibility, backup requirements, and modularity—that make them unsuitable for simple one-to-one matching with firm power plants. Instead, the author advocates for a 'system of systems' approach combining clean energy portfolios, battery storage, and demand-side flexibility. Key recommendations for policymakers include using the interconnection process as leverage to ensure cost causation and exploring demand-side resources, such as sponsoring household energy upgrades, to free up grid capacity.

Connection Costs Loophole Costs Customers Over $4 Billion to Connect Data Centers to Power Grid
The Union of Concerned Scientists (UCS) reports that utilities in seven PJM states passed over $4.3 billion in data center connection costs to all customers in 2024. This occurs because large data centers (100–1,000 MW) require high-voltage transmission infrastructure, which falls under federal FERC jurisdiction and is typically allocated across all customers, unlike low-voltage distribution connections. UCS finds that in 95% of cases, these costs are not paid by the data center owners. The brief recommends that FERC and state PUCs require utilities to track and assign these specific costs to the customers causing them.
