Climate Central's analysis reveals that the average person globally lost nearly 56 hours of sleep annually due to nighttime heat from 2020 to 2025, with approximately six hours attributed to climate change. The most significant climate-linked sleep losses occurred in Middle Eastern cities, where residents in Saudi Arabia, Oman, and the UAE lost between 12 and 16 hours of sleep per year due to climate change. Globally, the amount of temperature-related sleep loss linked to climate change has at least doubled since the early 1970s, increasing from about two hours to five hours per year. Vulnerable populations, including adults over 65 and those in lower-middle-income countries, face higher risks, and while air conditioning provides some protection, access remains unequal and tied to income.

In Q1 2026, U.S. clean energy investments were heavily influenced by executive branch implementation and policy certainty. While electric power investments increased—driven by a massive nuclear project in Texas—manufacturing investments declined for the sixth consecutive quarter. Federal support strongly favored critical minerals and battery storage, while sectors like hydrogen, solar, and sustainable aviation fuel (SAF) faced mixed outcomes due to fragile policy support and tightened tax credit eligibility windows.

The guide describes advance market commitments (AMCs) as financial mechanisms where governments or private entities guarantee the purchase of a future product to stimulate development and reduce investor risk. It outlines the essential steps for designing an AMC, including defining market boundaries, identifying eligible suppliers and buyers, and establishing standards and procurement processes. The text highlights the utility of AMCs for sectors like aviation, buildings, hydrogen, and carbon dioxide removal, while noting that they should be complemented by other policies to address infrastructure gaps.

The report analyzes the evolution of 'net zero' and 'nature positive' concepts, detailing how they are operationalized through taxonomies and methodologies in the financial sector. It highlights the interdependence of climate and nature crises, arguing for an integrated 'net-zero nature-positive' (NZNP) finance approach to manage compounding risks and leverage synergies, while noting that a unified NZNP definition and measurement protocol do not yet exist.

The document serves as a practical manual for identifying carbon projects within a specific country and evaluating their project documents. It explains the differences between Article 6.2 (decentralised), Article 6.4 (centralised), Voluntary Carbon Markets (VCM), and REDD+ programs. The guide directs users to specific digital tools—such as the UNEP Article 6 pipeline platform, the UC Berkeley Voluntary Registry Offsets Database, and the REDD+ Web Platform—to find project data. It also provides a framework for analysing project documents, focusing on geographic scope, actor roles, timelines, methodologies, and benefit-sharing arrangements, while highlighting industry quality criteria like additionality, leakage, and permanence.

The analysis finds that recent federal policy shifts—including the One Big Beautiful Bill Act (OBBBA) and the repeal of various EPA standards—will lead to higher energy costs for households, significant GDP and job losses, and increased healthcare spending due to worsening air pollution. While a temporary boom in renewables is expected due to safe-harbor tax credit rules through 2030, the report forecasts a sharp contraction in clean energy capacity and a continued reliance on coal power after 2031.

The report analyzes the strategic use of joint ventures by private equity (PE) firms to enter healthcare markets, leveraging the reputation of nonprofit partners to scale operations. Through case studies of Lifepoint Health, Ascension, Compassus, and Ardent Health, it documents patterns such as sale-leaseback real estate transactions, the use of nonprofit referral networks, and declining care quality. It argues that current IRS and state regulations are insufficient to oversee these complex structures and recommends expanded oversight of management fees, control rights, and charitable asset transfers.

The document is a formal statement by a coalition of state attorneys general and local officials opposing federal legislation that would shield fossil fuel companies from state-level lawsuits regarding climate deception and consumer protection violations.

Despite the removal of federal tax credits for clean energy upgrades via the One Big Beautiful Bill Act of 2025, residential clean technologies in the US continue to offer significant greenhouse gas emissions reductions and cost savings. Using the Green Upgrade Calculator, RMI found that electric vehicles (EVs) generally lead in emissions reductions and cost savings in the West, while air-source heat pumps (ASHPs) are most effective for emissions in the Northeast and Midwest and for savings in the South. Rooftop solar provides the highest emissions impact in Hawaii and leads in cost savings in California, Florida, and the Northeast due to high electricity prices and sunlight. The report emphasizes that the most effective state and local programs will target specific household archetypes—such as high-mileage drivers for EVs or delivered-fuel users for ASHPs—and bundle technologies to maximize synergy and savings.

The document outlines the technical processes of hydraulic fracturing and its associated risks, including greenhouse gas emissions during drilling and the release of carcinogens and radioactive materials in 'produce-water'. It synthesizes literature linking UOGD to adverse birth outcomes, childhood cancers, and increased mortality. Additionally, it criticizes the Nova Scotia government's Subsurface Energy Research and Development Investment Program (SERDIP), managed by Dalhousie University, for lacking a clear health research plan and allowing the government to control the publication of findings.

This fact sheet from the Environmental and Energy Study Institute describes the role of lithium in the energy transition, its global supply chain, extraction methods, and the environmental and social impacts associated with its production.

The document outlines a comprehensive framework for LDAR programs, emphasizing that well-implemented programs can reduce methane leaks by nearly 80%. It details the technical application of OGI cameras, a structured nine-step survey process—from planning to data reporting—and a typology of common leak sources such as valves, flanges, and compressor seals. The guide also provides regulatory benchmarks for survey frequency, repair timelines, and reporting templates to ensure accountability and effectiveness in methane mitigation.

The report argues that fossil fuel interests use corporate lobbying, trade associations, and advisory roles to maintain the availability of cheap, low-quality carbon credits to avoid structural decarbonization. It details specific efforts to weaken California's cap-and-trade program and oppose transparency laws like AB 1305, while highlighting the role of the CFTC in federal oversight. The document concludes with recommendations to ban fossil fuel companies from climate advisory roles and eliminate carbon credits from California's compliance mechanisms.

The document argues that current annual matching for scope 2 emissions often overestimates renewable electricity use and fails to incentivise the deployment of new renewables. It proposes 'hourly matching' (or 24/7 reporting), where electricity consumption is matched with renewable generation in the same hour. While 100% hourly matching can be costly, the briefing suggests that targeting a range of 80-90% can maintain emission reduction benefits while reducing costs. The document notes that hourly matching is becoming more viable, with 45 operational projects across five continents and tariffs available for 73% of global electricity demand. It advocates for a phased implementation strategy to allow for necessary data and grid infrastructure upgrades.

Earthjustice's Counter/Act report details its multifaceted legal and advocacy response to the second Trump administration's environmental policy rollbacks. The organization has scaled up litigation, launched a dedicated enforcement team to fill gaps in federal oversight, and shifted focus toward state-level protections for clean energy and public health. Key achievements include defending electric vehicle infrastructure, challenging the repeal of the endangerment finding, and securing state-level wins on landfill emissions in Colorado and environmental justice laws in New Jersey.

The report identifies that approximately 80% of residential EV charger projects in Chile are rejected by co-owner communities because electrical networks are classified as common property under Law No. 21.442, requiring high assembly quorums for any intervention. While technical standards (RIC N°15) and urban ordinances (OGUC) provide pathways for installation, they do not override the need for community consent. Comparing jurisdictions in the US, Europe, and Brazil, the report finds a global trend toward recognizing an individual's right to install charging infrastructure. It concludes that the only scalable solution for Chile is a punctual modification of Law No. 21.442 to allow installations via simple notification, provided the owner bears all costs and adheres to safety standards.

The Multi-Family Housing Tracker documents the significant increase in private equity ownership of U.S. apartment complexes, noting that 228 identified firms own nearly 3 million units, or approximately 13% of the national total. The report highlights a heavy concentration in Sunbelt states and metropolitan areas, correlating these regions with sharp increases in 'cost-burdened' renters. It details a business model focused on rapid value increases through rent hikes and additional fees, while documenting widespread tenant complaints regarding poor maintenance, aggressive evictions, and the use of algorithmic pricing software like RealPage. The document concludes with recommendations for landlords, public officials, and institutional investors to implement rent caps, just-cause eviction protections, and responsible investment standards.

The document highlights the systemic environmental inequality facing Latino communities in the U.S., who are nearly three times more likely than white communities to live in areas with the worst air pollution. It identifies fine particulate matter (PM2.5) and ground-level ozone as primary threats, exacerbated by methane emissions and wildfire smoke. The text warns that rollbacks of EPA protections, including the dismantling of the Good Neighbor Rule and the erasure of the 2009 Endangerment Finding, threaten public health. It concludes by demanding enforceable air quality standards, investments in green infrastructure, and a transition to renewable energy.

The report argues that traditional conservative utility planning, which bases connection decisions on worst-case load scenarios, creates lengthy delays for electric truck charging sites. Flexible service connections (FSCs) offer an alternative where customers agree to limit charging during peak hours to ensure grid safety, reducing energization timelines from years to months. RMI's analysis of Pacific Gas & Electric (PG&E) and National Grid data shows that FSCs are most effective on feeders with sharp, narrow late-afternoon peaks, typically near large population centers. In PG&E territory, just four hours of load shifting could theoretically support more medium- and heavy-duty electric vehicles than have been sold to date in California. The report highlights the role of managed charging and on-site battery storage in making FSCs operationally viable for fleets and calls for regulators to standardize these offerings.

Virtual power plants (VPPs) are reaching scales that rival traditional power plants, with some programs exceeding 1 GW. Despite this, the document finds that utilities often fail to properly model VPPs in integrated resource plans (IRPs) and distribution system plans (DSPs), frequently treating them as fixed load adjustments rather than selectable resources. This planning gap leads to an underestimation of VPP value and a risk of redundant infrastructure investment. The author recommends that regulators and utilities develop detailed resource attributes for VPPs, allow for their growth in models, and evaluate their benefits across both bulk power and distribution systems.
