The Union of Concerned Scientists asserts that the United States requires federal legislation to overcome barriers in the planning and siting of transmission lines, which currently hinder the deployment of renewable energy. The document advocates for 'Green Energy Superhighways' to connect remote renewable resource areas to population centers, while emphasizing that federal authority should act as a backstop when states cannot agree on facilities of national interest. It warns that without a federal cap-and-trade system, transmission expansion in the Northeastern United States could inadvertently increase carbon emissions by allowing coal-based power to flow from non-RGGI states to those with emission caps.

The report argues that RGGI's design, which caps emissions only for power plants within participating states, creates a price advantage for imported electricity from coal-heavy states like West Virginia and Pennsylvania. This 'leakage' is exacerbated by excess capacity in existing coal plants and planned transmission upgrades that facilitate power flow from west to east. The authors suggest that RGGI states should implement retail-level carbon caps, prohibit contracts with high-emission plants, and prioritize transmission projects aligned with climate goals to prevent the expansion of coal-based power.

The report warns that the Regional Greenhouse Gas Initiative (RGGI) risks 'undercutting itself' because it only prices emissions from power plants within its region. This creates an economic incentive for electricity suppliers in RGGI states to import cheaper, carbon-intensive power from coal-producing states like West Virginia and Ohio. The document provides 'carbon math' showing that utilizing excess capacity from 15 existing coal plants could produce pollution 'three and a half times the cuts expected under the initiative,' and that six plants under construction nearby could emit pollution equal to '140 percent of RGGI’s reductions.' To prevent this 'leak,' the authors suggest capping the entire portfolio of local electricity suppliers, limiting contracts with polluting plants, and requiring suppliers to account for emissions from electricity produced outside the region.

The 2006 School Bus Pollution Report Card by the Union of Concerned Scientists finds that U.S. school buses are among the oldest vehicles on the road, with an average age of nine years, and emit nearly twice as much soot per mile as tractor-trailer trucks. The report grades states on tailpipe soot emissions, smog-forming pollution, and the success of their cleanup programs. While some states like California and Washington have made significant strides in reducing soot through retrofits and cleaner fuels, national soot pollution from school buses has only decreased by more than two percent. The document highlights the vulnerability of children to diesel exhaust, which is linked to asthma and lung growth deficits, and argues that substantial federal and state investment is needed for bus replacement and the installation of particulate traps.

The report evaluates U.S. school bus emissions, finding that older diesel buses release significantly more soot than modern alternatives, posing health risks to children. It grades states on soot emissions, cleanup programs, and smog-forming pollution, noting wide performance gaps. The authors recommend a strategy of 'the five Rs'—retrofitting, refueling, replacement, repair, and reduced idling—and call for strengthened federal standards and increased funding to modernize fleets.

The document details how the U.S. Department of the Interior, under the direction of Deputy Secretary J. Stephen Griles, shifted the focus of a court-mandated environmental impact statement (EIS) from minimizing environmental damage to streamlining coal-mining permits. Despite federal agency data showing that mountaintop removal mining caused the loss of over 1,200 miles of streams and 7% of Appalachian forests between 1985 and 2001, the administration allegedly stripped 'significant' or 'severe' language from reports and omitted substantive alternatives to mitigate damage. The report highlights a conflict of interest, noting Griles' former role as a mining lobbyist and his frequent meetings with industry representatives during the EIS's redirection.

The Clean Air Task Force argues that the EPA's 2004 decision regarding cooling water intake structures for existing power plants is too weak because it replaces technology mandates with vague performance standards and allows for fish population 'restoration' instead of preventing kills. The document highlights that once-through cooling systems, used by 52% of U.S. plants, cause massive fish mortality and thermal pollution, whereas recirculating cooling could reduce water use by 95%.

The report evaluates the emissions of US school bus fleets, finding that the vast majority rely on high-polluting diesel engines that pose significant health risks to children. It advocates for a transition to cleaner alternatives, specifically natural gas, and calls for federal and state funding to replace aging fleets.

The Clean Air Task Force (CATF) contends that the EPA's proposed MACT standards for coal-fired utility units violate the Clean Air Act (CAA) by using arbitrary subcategories based on coal rank and flawed statistical methods to inflate emission floors. CATF argues that the EPA has ignored available, cost-effective technologies—such as activated carbon injection and fabric filters—that could achieve significantly higher mercury removal rates. The document further asserts that the EPA is legally obligated to regulate all HAPs emitted by these units, not just mercury and nickel, and that proposed compliance extensions are unauthorized and unnecessary given available labor and equipment resources.

The Mid-Atlantic Clean Hydrogen Hub (MACH2) is projected to create 20,800 direct jobs, including 14,400 in construction and 6,400 permanent positions, through 15 major projects across Pennsylvania, Delaware, and New Jersey. The hub involves a wide network of partners spanning hydrogen production, education, industrial applications, labor, supply chain, infrastructure, and transportation.

A letter dated February 28, 2006, from several U.S. state Attorneys General to the House Committee on Energy & Commerce opposing specific provisions of HR 4591. The bill aims to implement the Stockholm Convention on Persistent Organic Pollutants (POPs Treaty), but the signees argue it contains overly broad preemption language and flawed EPA review procedures that would hinder state and federal environmental protections.

Analysis shows that the weighted average cost of coal power in the U.S. rose from $36/MWh in 2021 to $46/MWh in 2024, a 28 percent increase that outpaced inflation. This rise is attributed to higher fuel, operations, and maintenance costs, as well as declining capacity factors. Despite these economics, some U.S. federal policies and state regulators have extended the lives of expensive plants, such as Plant Bowen in Georgia and the Hunter and Huntington plants in Utah, potentially increasing the financial burden on electricity consumers.

The document outlines a scalable governance model for early-stage alternative local capital providers in Africa, distinguishing between Limited Liability Partnerships (LLPs) and Investment Companies (Investcos). It details three core pillars of governance—legal structures and agreements, decision-making bodies, and people, policies, and processes—and provides a phased approach from 'foundational' to 'expanded' measures as funds grow in size and complexity. The framework includes specific checklists for key documents like Limited Partnership Agreements (LPAs) and Investment Policy Manuals, while offering good practice examples from African-focused funds such as First Circle, Catalyst Fund, and Aruwa.

Global Witness alleges that Claudia Sassou-Nguesso, daughter of the President of the Republic of the Congo, used approximately $20 million in diverted public funds to purchase a $7.1 million luxury apartment (unit 32G) at the Trump International Hotel & Tower in Manhattan. The investigation details a complex financial trail involving the Brazilian company Asperbras, which allegedly inflated contracts for geological mapping and hospital construction in the Congo. Funds were routed through a Delaware subsidiary (Asperbras LLC), a British Virgin Islands entity (Energy & Mining Asp. Inc.), and a Cypriot shell company (Sebrit Limited) controlled by intermediary José Veiga on behalf of Sassou-Nguesso. The purchase was facilitated by the law firm K&L Gates LLP via a New York shell company, Ecree LLC. Global Witness argues that the Trump Organization and K&L Gates failed to perform adequate due diligence on a Politically Exposed Person (PEP), potentially facilitating money laundering.

The report provides a state-by-state breakdown of progress toward 2020 Clean Power Plan benchmarks, noting that some states have exceeded 500% of their goals while others show 0% progress. It highlights the role of energy efficiency, renewable energy standards, and regional initiatives in achieving these targets.

The guide details five financial tools to facilitate energy efficiency: on-bill financing, Property Assessed Clean Energy (PACE) financing, Sustainable Energy Utility (SEU) models, loan guarantees, and loan loss reserve funds. It highlights how public investment can reduce lender risk to mobilize private capital, providing specific examples from the United States, Canada, and China.

The document outlines four types of solar metering arrangements designed to overcome the limitations of the traditional "one customer, one meter" model. Net metering provides benefits to a single customer via one meter. Virtual net metering (VNM) allows multiple customers with separate meters to share credits from a system, often in multi-tenant or municipal buildings, and is permitted in states including California, Colorado, and Massachusetts. Community solar enables joint ownership or sponsorship of systems for those unable to host arrays on-site, utilizing models such as utility-sponsored, special purpose entity, or non-profit "buy a brick" projects. Meter aggregation allows a single customer with multiple utility accounts to aggregate annual consumption across separate buildings, enabling the installation of larger systems and higher power sales back to the grid.

The document examines various employee ownership models—Employee Stock Ownership Plans (ESOPs), worker cooperatives, and Perpetual Purpose Trusts (PPTs)—evaluating their capacity to support environmental sustainability and worker equity. It argues that PPTs are particularly effective for mission-driven companies because they allow trustees to prioritize non-financial goals and protect a company's purpose in perpetuity, unlike ESOPs which are constrained by fiduciary duties to maximize financial benefits. The paper highlights the potential for PPTs to facilitate sustainable succession for aging US farmers and cites examples like Patagonia and the Organically Grown Company to illustrate the model's application.
