The document argues that relying solely on voluntary corporate credits is insufficient for scaling CDR and proposes three diversified demand pathways: credit purchasing through government procurement and compliance markets, demand for differentiated low-carbon products enabled by carbon accounting and 'Buy Clean' policies, and 'flipping the script' by funding services where CDR is a co-product, such as wildfire prevention or waste management.

The document argues that the EPA's 2026 proposed rule to weaken the Risk Management Program (RMP) is unlawful, arbitrary, and contrary to the Clean Air Act's mandate to prevent accidental chemical releases. The commenters contend that the proposal prioritizes industry cost savings and deregulatory executive orders over public health and safety, specifically threatening vulnerable populations and children. They call for the full implementation of the 2024 SCCAP Rule, the restoration of the RMP Public Data Tool, and the retention of critical safety requirements including safer technology analyses, third-party audits, and natural hazard planning.

The US electric grid faces severe supply chain constraints, with lead times for large power transformers reaching up to four years and prices for power line cables doubling since 2019. Domestic production is insufficient, meeting only 20% of demand for large power transformers in 2025. To address this, the document proposes a three-pronged federal strategy: easing near-term bottlenecks through allied partnerships and production ramps; expanding domestic capacity via manufacturing tax credits and low-cost scaling capital; and promoting innovation in next-generation grid hardware. It also highlights subnational opportunities for states to attract investment through tailored workforce training and industrial clustering.

Climate Central analyzed data from 476 weather stations to track fire weather trends in the contiguous U.S. between 1973 and 2025. The analysis reveals a significant increase in fire weather days, particularly in the western U.S., where conditions are intensifying in spring and summer. While the eastern U.S. has seen smaller increases, some areas in the Southeast and Northeast are experiencing more frequent fire weather. The report highlights that climate change is driving these trends through warming temperatures and decreasing relative humidity, which prime landscapes for wildfires to ignite and spread.

Leaders from GreenLatinos and other organizations advocate for the preservation of Latino, Chicano, Hispanic, and Indigenous histories within U.S. national parks and public lands. They condemn efforts to erase these narratives, remove Spanish-language resources, and dismantle environmental protections. The statement links the spirit of resistance associated with Cinco de Mayo to current struggles against climate change, inhumane migration policies, and the erasure of scientific truth and civil rights history in federal spaces.

The report argues that next-generation geothermal, specifically enhanced geothermal systems (EGS), can provide the 'clean firm' power California needs to reach its 2045 goals affordably. Modeling shows that EGS could reduce annual electricity supply costs by $10-44 billion and decrease the required pace of solar installation from 10 GW/year to 3 GW/year. While projects are currently being developed in other western states, the authors argue that in-state development would further save $3.5-5.5 billion annually and reduce interregional transmission needs by 28-53%. To overcome the 'missing middle' of financing for high-risk exploration wells, the report recommends California establish a public subsurface mapping and testbed program similar to the DOE's FORGE project in Utah.

The report argues that substituting tax-exempt public debt for investor-owned utility (IOU) equity and taxable debt can significantly lower transmission costs for ratepayers in New England. It identifies two primary paths: strengthening existing quasi-public entities or creating a new purpose-built transmission authority. The author emphasizes that any such vehicle must have a clear statutory mandate for FERC-jurisdictional transmission, non-recourse revenue-bond authority, the ability to form public-private partnerships, and governance structures that ensure state accountability and risk control.

The report argues that New England's transmission costs are the highest in the U.S., driven by a lack of cohesive planning and a reliance on expensive private capital. It proposes replacing private equity and debt with low-cost, tax-exempt public financing, which could save ratepayers up to $8.3 billion on new transmission and $1.1 billion on asset condition projects. The authors suggest several implementation pathways, including integrating public financing into ISO New England's Longer-Term Transmission Planning (LTTP) process or creating new state transmission authorities.

The report details how private equity firms have acquired Medicaid contractors to capitalize on government-backed revenue, often leading to operational failures. It highlights systemic payment errors and wage theft allegations at Public Partnerships, LLC; massive debt-driven cost-cutting and fraud allegations at Gainwell Technologies; and delays in care authorizations and the use of offshore labor at Acentra Health. The document also warns of the risks associated with AI-driven analytics and the offshoring of sensitive patient health information to India.

The report highlights that over 66 million people in the US live near freight facilities, with higher concentrations of warehouses linked to increased cancer risks and air pollution. It advocates for Indirect Source Rules (ISRs), which require facilities to mitigate the 'indirect' emissions they attract, citing California's WAIRE program as a successful model for increasing zero-emission vehicle adoption and infrastructure.

The report identifies that over 66 million people in the U.S. live near freight facilities and corridors, with those near clusters of 11 or more facilities facing a 32% higher cancer risk from air toxics than the national average. It advocates for Indirect Source Rules (ISRs), which require facilities to mitigate the pollution attracted by their operations, as a tool to address these disparities. The author details best practices for ISR design and proposes various compliance options, including the deployment of zero-emission vehicles, charging infrastructure, and innovative solutions like using wastewater treatment plant methane for port power.

The document examines the surge in data center demand in California, driven by generative AI, and warns that without new statewide policies, this growth could increase electricity costs for ratepayers, delay the clean energy transition, and threaten grid reliability. It highlights the risks of fossil-fueled backup generators on local air quality and recommends that data centers pay for their own clean energy generation and grid connection costs.

The Private Equity Stakeholder Project supports Illinois HB5000, arguing that private equity's expansion into healthcare—through leveraged buyouts, roll-ups, and joint ventures—often leads to higher prices, increased debt, and reduced quality of care. The document details specific financial tactics like sale-leasebacks and dividend recapitalizations, and highlights the growth of private equity in ambulatory surgery centers and physician practice management, urging regulators to increase oversight to protect patient access and cost.

The report finds that by 2025, fossil fuel power generation fell below its peak in all 38 OECD member countries, driven by the rapid scaling of solar and wind energy. This trend is extending to emerging markets, with 2025 marking the first year this century (excluding 2020) that non-OECD fossil generation fell, specifically in China and India. The transition is increasingly driven by economic imperatives, as the levelized cost of solar and onshore wind is now 60% lower than combined cycle gas turbines.

A severe marine heat wave is impacting the northeast Pacific Ocean, with temperatures 2-5°F above normal and peak anomalies reaching 11°F. The event is strongly influenced by human-caused warming, which has increased the heat wave's footprint and duration.

In 2025, clean power met all global electricity demand growth for the first time since the pandemic, as China's fossil generation plateaued. Solar power is the primary driver of this shift, and the deployment of battery storage is increasingly enabling solar to displace fossil fuels during non-daylight hours. India is expected to follow a less coal-reliant path than China due to lower energy intensity and the maturity of low-cost clean technologies.

The report provides a detailed analysis of the power sectors of seven major countries and regions in 2025, which collectively represent 72% of global electricity demand. Key trends include China's unprecedented solar growth and first absolute decline in power sector emissions since 2015, the US seeing wind and solar overtake nuclear power for the first time, and the EU's wind and solar generation exceeding fossil generation. India saw renewable growth double its demand increase, while Brazil maintained one of the cleanest systems globally with 87% renewable generation. Conversely, Russia and Japan continue to rely heavily on fossil fuels, with Russia's wind and solar remaining marginal at less than 1% of its mix.

RMI and OTS R&D conducted laboratory tests on residential split systems and packaged rooftop units to determine if reclaimed R-410A refrigerant, processed to AHRI 700 standards, performs differently than virgin refrigerant. The results showed no statistically significant differences in heating capacity, cooling capacity, or energy efficiency across all tested operating conditions. The report argues that scaling refrigerant recovery and reclamation is essential to bridge the structural gap between declining HFC production under the AIM Act and the ongoing servicing demand for existing equipment, particularly for R-410A, which served approximately 85% of US residential and 92% of light commercial cooling systems in 2022.

The Council on Strategic Risks describes a workshop in California that explored how extreme weather events, such as wildfires and droughts, can be leveraged by opportunistic actors to spread mis- and disinformation. The report identifies key uncertainties regarding generative AI, institutional capacity, and public trust, and presents three divergent future scenarios for the state: a 'muddling through' crisis, a geopolitical collapse triggered by conflict in the Pacific, and a positive social transformation in water management. It concludes that information manipulation is a persistent risk to disaster response and national security, necessitating cross-sector partnerships for resilience.

The policy brief outlines seven critical functions that U.S. states perform to advance clean energy and climate goals, emphasizing that state-level action is resilient to federal political swings and provides scalable models for emissions reductions and economic development.
