Upgrading the millions of US homes relying on electric resistance heating to air-source heat pumps (ASHPs) and heat pump water heaters (HPWHs) offers significant benefits for affordability, grid reliability, and climate goals. For single-family homes, these upgrades can save households an average of $1,530 annually and reduce total carbon pollution by approximately 40%. At scale, such transitions could reduce US residential summer peak demand by 11 GW and winter peak demand by 51 GW. The report advocates for updating building energy codes to discourage electric resistance in new construction and retrofits, setting specific replacement targets, and implementing midstream incentive programs and on-bill financing to overcome up-front cost barriers.

A review of fifteen large private equity evergreen funds reveals they significantly underperformed the S&P 500 and MSCI ACWI indexes in 2025 and over a three-year period, despite charging median expense ratios of 3.76% compared to 0.03% for the Vanguard S&P 500 ETF. The report notes that the private equity industry is seeking a regulatory safe harbor from the US Department of Labor to limit lawsuits as it targets 401K retirement savings, a shift occurring as global fundraising fell 11.0% in 2025 and several US state pension funds—including those in Alaska, Texas, and Ohio—reduced their private equity allocations due to dwindling returns and liquidity risks.

In 2025, the U.S. experienced 23 billion-dollar weather and climate disasters costing $115 billion, ranking it the third-highest year on record. The year was dominated by a record 21 billion-dollar severe storm events and the costliest wildfire in U.S. history, the Los Angeles wildfires. Since 1980, the frequency of such disasters has surged, with the average time between events dropping from 82 days in the 1980s to just 10 days in 2025.

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.

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.

The document challenges the narrative that wind and solar power drive up electricity costs, asserting that real-world data from multiple global markets often shows an inverse relationship. It highlights that in the US and EU, regions with higher-than-average renewable shares frequently have lower-than-average household power prices. While acknowledging that factors like transmission costs, wildfire mitigation, and market liquidity can influence prices, the briefing concludes that renewables generally lower wholesale costs by displacing expensive fossil fuels.

Washington State faces escalating risks from drought, wildfires, extreme heat, and coastal flooding, which threaten its economy, ecosystems, and critical US military installations. While federal agencies like NOAA and FEMA provide essential forecasting, funding, and disaster recovery services, the report argues that recent and proposed budget cuts for FY2026—including the termination of key research laboratories and the reduction of grant programs—significantly degrade the state's capacity to prepare for and respond to these hazards.

The U.S. produces and consumes approximately 14 million metric tons (MMT) of hydrogen annually, with over 90% of demand concentrated in petroleum refining, ammonia, and methanol production. While current production is dominated by steam methane reforming (SMR), the report projects significant demand growth by 2050 from aviation, marine, and on-road transportation, potentially adding 40-50 MMT/yr. The report argues for prioritizing decarbonization in existing industrial corridors, particularly along the Gulf Coast, while preparing for these emerging sectors.

In 2025, the contiguous U.S. experienced its fourth-warmest year on record and 23 billion-dollar weather and climate disasters, totaling $115 billion in damages. Globally, 2025 was the third-warmest year since 1850, with NOAA data indicating it was approximately 1.3°C warmer than the pre-industrial average. The year was marked by record-breaking December heat in the U.S. Southwest and devastating atmospheric river flooding in Washington and Oregon.

The document reports that November 2025 was the third warmest on record globally and the fourth warmest for the contiguous U.S. It highlights a long-term trend of warming winters in the U.S., where the coldest day of the year has warmed by approximately 7°F since 1970. The briefing also notes significant regional anomalies, such as extreme warmth in Texas and heavy rainfall in southern California, while discussing the ongoing La Niña advisory and its expected impacts on weather patterns through early 2026.

A joint statement by five Canadian environmental and health organizations—Ecojustice, Breast Cancer Action Quebec, the Canadian Association of Physicians for the Environment, the David Suzuki Foundation, and Environmental Defence—providing feedback on the 'Consultation Document on Phase 1 of the Risk Management of Per- and Polyfluoroalkyl Substances (PFAS), Excluding Fluoropolymers: Prohibition of the Use of PFAS, not Currently Regulated, in Firefighting Foams'. While the organizations support the proposed risk management measures and their alignment with European Union and Washington State standards, they strongly criticize the proposed implementation timelines, which could allow some facilities to use PFAS-containing foams until 2039.

Earthjustice responds to a DOE request for information on accelerating power delivery for AI and industrial growth. The organization argues against reviving retired coal plants due to high costs and unreliability, instead advocating for the rapid deployment of wind, solar, and battery storage. It recommends that the DOE address speculative and inflated data center load forecasts, automate interconnection studies to reduce timelines, and deploy Advanced Transmission Technologies (ATTs) to increase grid capacity quickly. Additionally, it emphasizes the need for early community engagement in permitting and the long-term expansion of interregional transmission lines.

Analysis of 244 U.S. cities shows that winters are the fastest-warming season for most of the country, with average temperatures increasing by 3.9°F since 1970. This trend is characterized by fewer freezing nights, shorter cold streaks, and a significant increase in warmer-than-normal winter days, particularly in the Northeast and Upper Midwest. These changes threaten mountain snowpack, crop yields for the $27 billion fruit and nut industry, and the winter recreation economy, while potentially increasing pest-related health risks and allergy durations.

RMI highlights the transition from climate commitments to action across several global regions. China is leading in renewable deployment and clean tech exports, while Brazil focuses on low-carbon shipping and ambitious NDCs as the COP30 host. India is pursuing energy independence by 2047 through clean mobility and cooling innovations. Southeast Asia is scaling clean infrastructure and battery storage, and the United States continues to see subnational progress in grid optimization and clean industrialization despite federal delegation concerns.

The Big Eddy-Knight project, a 28-mile transmission line completed in 2015 by the Bonneville Power Administration (BPA), utilized a proactive settlement agreement with the Friends of the Columbia River Gorge (FOCG) to mitigate environmental impacts and reduce litigation risk. While the agreement established a $1.78 million mitigation fund primarily used for land conservation and some utility upgrades, it faced criticism from local landowners and Klickitat County officials who felt the benefits did not directly address the impacts on those most affected by the project's footprint. The project also involved complex consultations with the Yakama Nation and other Tribes, leading to route adjustments to protect cultural resources, including a cave with ancient drawings.

The report examines community benefits frameworks (CBFs) across six completed U.S. transmission projects, finding that early, meaningful engagement and tailored benefits—such as infrastructure upgrades, land conservation, and co-ownership—are essential for reducing opposition and avoiding costly delays. It highlights that while financial compensation is common, non-monetary benefits and innovative financing models, including Tribal co-ownership and nonprofit partnerships, provide more sustainable value. The analysis warns that delayed engagement or narrow benefit distribution can lead to litigation and community friction, emphasizing the need for regulatory flexibility and the use of trusted local messengers to build trust.

The 2025 State Healthcare Policy Review tracks a national trend of state-level efforts to regulate private equity in healthcare. It categorizes legislative approaches into transparency and reporting, approval and enforcement authority, targeted prohibitions, and Corporate Practice of Medicine (CPOM) enforcement. The report details laws passed in states like Massachusetts, California, Indiana, Oregon, New Mexico, Washington, and Maine, while also tracking pending and failed legislation in other states.

The document argues that fusion energy is transitioning from laboratory research to commercial viability, with many U.S. startups projecting grid connection by the first half of the 2030s. It outlines how states can create competitive advantages by implementing specific regulatory reforms, such as becoming an NRC Agreement State to manage radiological licensing, and by adopting legislative tools like explicitly defining fusion as a clean energy source in state statutes. The brief also suggests financial mechanisms including state-level investment tax credits, the creation of dedicated fusion energy funds, and the repurposing of retired fossil fuel sites—termed "fusion brightfields"—to leverage existing grid infrastructure. Additionally, it emphasizes the importance of developing specialized workforces and innovation hubs around universities and national laboratories to support the industry's growth.

As federal support for carbon dioxide removal (CDR) faces rollbacks, U.S. states are positioned to advance direct air capture (DAC) by aligning specific technology types with local assets. The report identifies a diverse range of DAC technologies—from fully electric systems to those requiring high-temperature heat—and maps them to state-level opportunities. For example, California's geothermal resources and Texas's renewable curtailment and CO2 infrastructure offer distinct advantages. While some states like Washington and Texas are suited for large-scale sequestration, others like Massachusetts can serve as innovation hubs for waste-heat recovery and CO2 utilization. The document emphasizes that maximizing climate benefit requires pairing DAC with low-carbon energy to avoid eroding net removals.

The policy brief examines the misalignment between legacy gas utility energy efficiency programs and current state climate goals in the United States. It highlights how traditional cost-effectiveness tests often prioritize short-term gas appliance rebates over high-impact weatherization and electrification. Using examples from states like New York and Massachusetts, the document proposes six strategic reforms to redirect ratepayer funding toward long-term decarbonization and building efficiency.
