The report identifies a 'methane emission gap' between the Obama Administration's goal to reduce oil and gas methane pollution by 40–45% from 2012 levels by 2025 and the actual impact of its proposed regulations. It finds that proposed standards primarily target new and modified sources, while existing sources are projected to represent 90% of the sector's total methane emissions in 2018. To close the gap of at least 75 million metric tons CO2e, the report recommends requiring leak detection and repair, non-emitting pneumatic technologies, and the capture of gas from oil wells for existing sources.

The document analyzes how carbon taxes or cap-and-trade programs affect U.S. households through expenditures, income, and revenue allocation. While carbon pricing can be regressive in terms of energy expenditures—disproportionately affecting low-income households and coal-dependent regions—the authors argue that the overall impact is determined by how the government uses the revenue. By targeting a small portion of revenue (approximately 10-12%) toward low-income households and coal communities, policymakers can offset burdens and ensure these vulnerable groups are not driven deeper into poverty. The brief compares various revenue uses, such as lump-sum rebates, labor tax swaps, and capital tax swaps, concluding that the policy is not inherently regressive and can be designed to be progressive.

Pennsylvania is required to reduce power sector emissions by 24-25 percent below 2012 levels by 2030 under the Clean Power Plan. Analysis indicates that current clean energy policies and improved power plant efficiency could achieve a 13 percent reduction by 2030. To fully meet or exceed targets, the state can expand its energy efficiency programs (Act 129) and alternative energy portfolio standard (AEPS) after 2021, potentially cutting emissions by 46 percent below 2012 levels by 2030. Such measures are described as cost-effective, with potential for the state to earn over $160 million annually by selling unused emissions allowances between 2022 and 2030.

The Union of Concerned Scientists proposes a green bank for Michigan, estimating that an initial public investment of $105 million could leverage $3.3 billion in total clean energy investments by 2030. This financial mechanism would support the deployment of 685 MW of solar capacity and reduce annual carbon dioxide emissions by 3.9 million tons, contributing 13% of the emissions reductions required for the state to meet Clean Power Plan targets. The document outlines various financial products the bank could offer, such as credit enhancements and warehousing, and identifies existing Michigan programs that could be integrated into this structure.

The Union of Concerned Scientists analyzes how a hypothetical Pennsylvania green bank, with an initial $135 million capitalization, could leverage $4.2 billion in total investment by 2030. This initiative would support 780 MW of wind and solar capacity, save $375 million annually on electricity bills, and reduce CO2 emissions by 4.8 million tons per year, contributing 11% of the state's required reductions under the Clean Power Plan.

The Union of Concerned Scientists developed a screening tool to identify coastal 'climate equity hotspots' where high climate risk overlaps with socioeconomic vulnerability. Applying this to 35 counties across the East and Gulf Coasts, the report finds that low-income and minority communities face disproportionate burdens from sea level rise and storm surges, often exacerbated by inadequate disaster recovery policies. It advocates for targeted federal funding, inclusive stakeholder engagement, and the use of actionable science to build resilience in frontline communities.

The Union of Concerned Scientists (UCS) report identifies coastal communities where socioeconomic vulnerability and climate risks overlap, creating 'climate equity hotspots.' Using a pilot study of 35 counties across nine U.S. states, the report demonstrates that African American, Latino, and Native American communities often face higher exposure to sea level rise and tidal flooding while possessing fewer resources to adapt. The authors propose a screening tool based on climate and socioeconomic indicators to guide more equitable distribution of federal and state resilience funding. The report concludes with policy recommendations to upgrade affordable housing, improve transportation for evacuations, and ensure inclusive stakeholder engagement in climate planning.

The Union of Concerned Scientists (UCS) identifies a critical need for equitable climate resilience planning in the United States, specifically for frontline coastal communities. The report introduces a screening tool that combines climate risk indicators (sea-level rise and tidal flooding) with socioeconomic data (income, poverty, race, and education) to identify 'climate equity hotspots'. Applying this tool to 35 counties across nine states, the analysis finds that the Gulf Coast and Mid-Atlantic regions face the highest risks, with Orleans Parish, Louisiana, identified as the most vulnerable hotspot. The report argues that current disaster aid often fails marginalized groups due to bureaucratic hurdles and a focus on homeowners over renters. It recommends that federal and state agencies direct funding to high-risk communities, integrate the best available climate science into planning, and increase overall funding for climate resilience.

The document details a screening methodology to assess the joint vulnerability of 35 U.S. coastal counties by combining socioeconomic data and climate projections. It utilizes a linear scaling technique to normalize variables—including per-capita income, poverty rates, and projected sea level rise—into composite risk indicators. The analysis incorporates historical damage data from SHELDUS and storm surge modeling for specific case studies to identify areas of high vulnerability.

The Union of Concerned Scientists analyzes how a hypothetical Virginia green bank with $90 million in initial capitalization could leverage $2.8 billion in total investment by 2030, significantly reducing carbon emissions and supporting the deployment of 575 MW of wind and solar capacity.

The report finds that significant portions of the U.S. East and Gulf Coast electricity grids are exposed to coastal flooding, with the Delaware Valley specifically facing risks to 79 substations and 35 power plants under current Category 3 hurricane conditions. It warns that reliance on historical flood data underestimates future risks as sea levels rise, potentially leading to widespread, long-lasting power outages. To address this, the authors recommend a combination of infrastructure adaptation (protection, accommodation, and retreat) and the deployment of decentralized clean energy technologies—such as solar with storage, combined heat and power (CHP) plants, and microgrids—to ensure critical facilities remain powered during grid failures while reducing the carbon emissions that drive sea level rise.

The Union of Concerned Scientists (UCS) analysis finds that two-thirds of U.S. states may be exposing electricity consumers to financial risks due to overreliance on natural gas. These risks include price volatility, potential carbon pricing costs, and the possibility of stranded assets such as underused plants and pipelines. The report rates states across five categories, identifying Florida as the only state with a "High" risk rating in all five. To mitigate these risks, the report advocates for prioritizing renewable energy and energy efficiency over natural gas as a primary solution for carbon reduction under the federal Clean Power Plan.

The report examines clean energy financing tools used by six U.S. states and Germany to scale up renewable energy and energy efficiency investments. It highlights the role of 'green banks' and other mechanisms in reducing financial risks for the private sector and overcoming barriers like high upfront costs and limited technical understanding among financiers. Case studies include Connecticut and New York's green banks, Pennsylvania and Kentucky's use of the Warehouse for Energy Efficiency Loans (WHEEL), Iowa's revolving loans, and Massachusetts's Mass Save HEAT Loan. The report concludes that these tools can help states achieve Clean Power Plan targets by leveraging limited public funds to attract significant private capital.

Earthjustice and a coalition of local governments and environmental groups are appealing the 'Hazardous Materials: Enhanced Tank Car Standards and Operational Controls for High-Hazard Flammable Trains' final rule. They contend that the rule violates the Administrative Procedure Act by abandoning the notification requirements of the May 2014 Emergency Order without public comment. The appeal argues that the new system—which relies on rail routing analysis and voluntary industry practices—provides retrospective, aggregated data that is less useful to first responders than the weekly, county-level notifications previously required. Furthermore, the petitioners argue that the DOT is improperly restricting public access to train route information by treating it as sensitive security or confidential business information without a legal basis.

The report outlines a toolkit for local governments to manage the rapid expansion of unconventional oil and gas development, such as hydraulic fracturing. It details regulatory options like zoning and setbacks, non-regulatory strategies including community engagement and contractual agreements, and fiscal tools such as severance taxes and road maintenance agreements. The document emphasizes the challenge of state-level preemption and the need for local officials to act as 'honest brokers' between industry and concerned residents.

A coalition of 290 organizations and individuals opposes H.R. 1734, asserting that the bill would weaken the U.S. Environmental Protection Agency's (EPA) 2014 coal ash rule. The signatories argue the legislation would delay health protections, eliminate public access to information, and remove national standards for drinking water protection, thereby increasing risks to vulnerable communities and the environment.

The report examines the transition of the U.S. power sector from coal to natural gas, noting that while this shift provides immediate benefits, it introduces risks such as price volatility, methane leakage, and potential 'stranded assets'. Using the National Energy Modeling System, the analysis compares a 'Business as Usual' scenario with a 'Carbon Standard plus Renewables and Efficiency Policies' scenario. The findings suggest that the latter would reduce power plant carbon emissions by 70 percent below 2005 levels by 2040, lower consumer energy bills, and provide significant net societal benefits, reaching nearly $170 billion by 2040.

The report examines the transition of the U.S. power sector from coal to natural gas, highlighting that while this shift provides immediate reductions in some pollutants, it creates long-term risks including price volatility, methane leakage, and stranded assets. Through modeling three scenarios—Business as Usual, a Carbon Standard, and a Carbon Standard plus Renewables and Efficiency Policies—the authors find that a diversified energy mix is the most economically and environmentally sound approach. The 'Carbon Standard plus Renewables and Efficiency Policies' scenario is projected to reduce power plant carbon emissions by 70% below 2005 levels by 2040 and generate net societal benefits of nearly $170 billion by that year. The report recommends strengthening the EPA's Clean Power Plan, implementing federal renewable electricity and energy efficiency standards, and increasing regulations on fugitive methane emissions.

The document outlines various energy storage technologies—including pumped hydro, batteries, thermal, compressed air, flywheels, and hydrogen—detailing how they balance electricity supply and demand. It highlights the transition from a reliance on pumped hydroelectric storage toward rapidly scaling lithium-ion batteries, noting a 72 percent drop in battery capital costs between 2015 and 2019. The guide argues that energy storage enhances grid reliability, enables higher renewable energy integration, and provides community benefits by replacing polluting fossil fuel 'peaker' plants and increasing resilience against extreme weather.

The document describes the four primary components of the US electricity grid: individual generators, transmission lines, distribution networks, and consumer load. It details the technical differences between power sources, such as the low flexibility of coal and nuclear plants compared to the rapid ramping of natural gas plants. The text outlines the regulatory roles of state Public Utility Commissions (PUCs) and the federal Federal Energy Regulatory Commission (FERC), and notes the three main US transmission networks: the Western Interconnection, the Eastern Interconnection, and ERCOT. It also traces the grid's history from the victory of alternating current (AC) over direct current (DC) to the 'restructuring' of the 1970s that allowed for wholesale competition. Finally, it identifies potential improvements through energy storage, smart meters, and distributed generation like residential solar panels.
