As of August 2021, fewer than 1% of U.S. school buses are electric, with 95% still relying on diesel. Adoption is led by California and Montgomery County, Maryland, though deployment is heavily skewed toward suburban areas (64% of committed buses). While some electric buses are in highly vulnerable communities, this is largely due to targeted funding in California. Federal initiatives like the American Jobs Plan and Bipartisan Infrastructure Framework provide scaling opportunities, though the report warns that funding 'clean' fossil-fuel alternatives like natural gas hinders decarbonization goals.

This report by the World Resources Institute (WRI) analyzes the adoption of electric school buses (ESBs) in the United States as of March 31, 2022. It tracks 'committed' buses—those awarded funding, ordered, delivered, or in operation—highlighting a significant increase in commitments driven by large-scale contracts and specific funding sources like the Volkswagen Settlement. The report also examines the distribution of these buses across different demographics and pollution levels to assess the equity of the transition.

This RMI fact sheet argues that the US Environmental Protection Agency (EPA) should use its authority under the Clean Air Act to establish nitrogen oxides (NOX) standards that phase in requirements for electric appliances. The document highlights the significant health, environmental, and climate impacts of fossil-fuel burning appliances, particularly gas appliances, and positions electrification as a cost-effective solution to reduce premature deaths and pollution.

This briefing by the Decommissioning Working Group argues that U.S. nuclear energy policy is not evidence-based and that the NRC is captured by industry interests. It highlights critical gaps in the management of decommissioning trust funds, the safety of spent fuel storage canisters, and the lack of safety standards for Small Modular Reactors (SMRs), recommending a shift toward science-based standards and increased Congressional oversight.

This fact sheet outlines several federal and partner-led programs designed to transition military veterans into civilian careers within the low-carbon workforce, specifically focusing on land management, agriculture, conservation, and fisheries.

This issue brief by the Environmental and Energy Study Institute examines the economic and workforce challenges facing coal-dependent communities in the United States as they transition to a clean energy economy. It analyzes the drivers of coal's decline, evaluates proposed federal strategies for a 'just transition,' and highlights regional opportunities for economic diversification in sectors such as renewable energy, environmental remediation, broadband deployment, and entrepreneurship.

The County of Dupage issued a USD 51 million self-labelled green bond on July 30, 2020, to refinance bonds and swap agreement costs related to The Morton Arboretum. The bond falls under the Land Use & Agriculture (Afforestation/parks) category. While the Climate Bonds Initiative welcomes the investment in tree science, it recommends the implementation of external reviews and ongoing reporting, as the issuer currently intends to provide no further reporting after issuance.

This fact sheet from the Environmental and Energy Study Institute (EESI) analyzes employment trends in renewable energy, energy efficiency, and climate resilience, focusing on the United States and global leaders. It utilizes data from the 2019 U.S. Energy Employment Report (USEER) and the International Renewable Energy Agency (IRENA) to quantify jobs across various green technology sectors.

This fact sheet provides a comprehensive overview of employment statistics in the renewable energy, energy efficiency, and climate resilience sectors, focusing primarily on the United States while providing global comparisons. It utilizes data from various sources, including the U.S. Energy Employment Report (USEER) and the International Renewable Energy Agency (IRENA), to detail job growth, sectoral distributions, and the challenges of quantifying emerging fields like climate adaptation.

The Illinois Finance Authority issued USD 450 million in revolving fund revenue bonds on April 16, 2019, to fund loans from the Illinois Environmental Protection Agency (IEPA) for wastewater treatment, sanitary sewerage, and drinking water facilities in Illinois. The issuance is noted for its high level of reporting granularity, with the IEPA providing annual project-level updates on the Illinois Financial Authority's website, a practice described by the Climate Bonds Initiative as a market best practice for US municipal issuances.

This report by the Rocky Mountain Institute (RMI) examines utility regulatory reform efforts across 10 U.S. states to identify effective processes for transforming the power sector. It argues that traditional quasi-judicial regulatory processes are inadequate for the scale and complexity of current energy transitions and proposes a four-stage framework—initiation, vision communication, conduction, and delivery of outcomes—to achieve more transformational results.

The Carbon-Free Regions Handbook: Electricity provides a framework for transitioning regional electricity systems to renewable or zero-emission energy. It outlines five primary actions: implementing ambitious Renewable Portfolio Standards (RPS), phasing out coal-fired generation through retirement and moratoriums, modernizing rate designs to include dynamic pricing, integrating distributed energy resources (DERs) into grid planning, and expanding community solar projects to increase accessibility.

This briefing, compiled by a coalition of public interest groups and published by the Environmental and Energy Study Institute, outlines the technical, economic, and regulatory challenges associated with decommissioning nuclear power plants in the United States. It highlights significant risks to public health and safety, the inadequacy of current waste storage and funding, and the lack of local government oversight during the decommissioning process.

The Climate Bonds Initiative conducted a scoping exercise to identify the potential for US municipal issuers to scale up green bond issuance. The study identified USD 264 billion in outstanding bonds from 1,436 'pure-play' climate-aligned issuers—entities deriving more than 95% of their revenue from climate solutions—most of which are not currently labeled as green bonds.

This report by the Rocky Mountain Institute (RMI) explores how electric utilities can move beyond traditional bill assistance to collaborate with low-and moderate-income (LMI) customers. It identifies new business models leveraging distributed energy resources (DERs) to reduce energy burdens, improve health and environmental outcomes, and create grid value.

This research paper examines the 'utility information problem'—the lack of data regarding the locational value of distributed energy resources (DERs)—which obscures the boundaries of the electric distribution utility's natural monopoly. The author proposes that integrated distribution planning (IDP) is necessary to reveal this information, enabling a transition toward a Distribution System Optimizer (DSO) role. The paper evaluates two pathways to this transition: an information-intensive approach compatible with cost-of-service regulation and an outcome-focused approach utilizing performance-based regulation (PBR).

This fact sheet describes the formation and goals of the United States Climate Alliance and other subnational efforts to uphold the 2016 Paris Agreement following the Trump Administration's decision to withdraw the United States from the accord.

This fact sheet from the Environmental and Energy Study Institute provides an overview of plug-in electric vehicles (PEVs), including battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs). It details the environmental and economic benefits of PEVs, the current state of the U.S. and global markets, charging infrastructure, battery technology trends, and government incentives.

This research paper by Energy Innovation outlines a five-step framework for state regulators to design grid modernization programs that maximize benefits for customers. The authors emphasize the use of outcome-oriented metrics across three primary goals—affordability, resilience, and environmental performance—and suggest tying utility revenue to performance against these targets to align incentives.

This World Resources Institute fact sheet provides data on employment growth within the United States clean energy economy, focusing on solar, wind, energy efficiency, and alternative fuel vehicle sectors as of early 2016 and 2017.
