This report analyzes the potential nationwide impact of California's Advanced Clean Cars II (ACC II) rule, which aims for 100% ZEV sales by 2035. It finds that if all 177 eligible states adopt the rule, the U.S. could reduce cumulative emissions by 1,310 MMT CO2e by 2050, prevent 5,000 deaths and 160,000 asthma attacks, and see the EV fleet grow to 239 million vehicles. The analysis emphasizes that while the Inflation Reduction Act (IRA) provides critical short-term incentives, state-level mandates are necessary for long-term sustainability.

This guide from the World Resources Institute explains buyer-led aggregated procurement of renewable energy for local governments in the United States, detailing the benefits, challenges, and strategies for successful implementation to advance decarbonization goals.

This guide by the World Resources Institute (WRI) examines the transition from internal combustion engine (ICE) school buses to electric school buses (ESBs) in the United States. It analyzes how the shift in cost structures—from lower upfront costs and higher operating expenses to higher upfront costs and lower operating expenses—creates a need for new business models to manage capital, risk, and infrastructure.

A November 2022 report by Global Energy Monitor (GEM) based on a 50-state survey reveals that major U.S. companies in the technology, banking, and insurance sectors frequently employ state-level lobbyists who also represent the fossil fuel industry. The report highlights a contradiction between these companies' public net-zero climate goals and their reliance on 'multi-client lobbyists' who promote continued fossil fuel dependence.

This guide by RMI describes resilience hubs as community-serving facilities designed to support vulnerable populations during and after extreme weather events. It outlines five foundational areas of support—power, communication, facilities, operations, and services—and provides six strategic lessons for cities implementing these hubs, emphasizing community partnership, energy efficiency, and the integration of solar and battery storage.

This RMI report provides recommendations for modernizing the regulatory processes of state public utilities commissions (PUCs) in the United States to accelerate the transition to a decarbonized and equitable electric grid. It identifies four primary areas for reform: setting clear proceeding objectives, expanding stakeholder roles in solution development, reducing information asymmetry through data transparency, and initiating new inclusive processes such as regulatory sandboxes and updated benefit-cost analysis frameworks.

This report by the International Institute for Sustainable Development (IISD), on behalf of the 'Electrifying Canada' private sector task force, outlines the requirements and obstacles for scaling up clean electricity production in Canada to achieve net-zero emissions by 2050. It argues that current utility planning is insufficient to meet the projected demand and proposes five catalysts—specifically focusing on regulatory mandates, proactive planning, and private investment—to accelerate the transition.

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 fact sheet by RMI defines green banks as public or quasi-public entities designed to leverage public funds to attract private capital for low-carbon, climate-resilient investments. It outlines their role in filling market gaps, reducing perceived risks for investors, and helping countries implement their nationally determined contributions (NDCs) under the Paris Agreement.

This research paper compares the electric vehicle (EV) policies of the United States and China, focusing on financial incentives, charging infrastructure, research and development, and fleet procurement. It highlights China's more aggressive approach to subsidies and mandates compared to the U.S. system of tax credits and state-level incentives.

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 RMI report evaluates time-based and demand charge electricity rates for mass-market customers. It finds that well-designed time-based rates (especially those with high peak/off-peak price ratios and active enabling technology) can significantly reduce peak load and total energy use without harming customer acceptance. In contrast, the report highlights a critical lack of empirical evidence for mass-market demand charges, noting that while they may aid utility cost recovery, their impact on customer behavior remains largely speculative.

This white paper proposes a Performance Incentive Mechanism (PIM) to encourage utilities to prioritize peak load reduction over capital-intensive infrastructure expansion. The author recommends using an outcome-oriented metric—specifically percentage reduction in peak load—and a sloped, symmetrical compensation structure with upper and lower caps to align utility incentives with system efficiency and customer value.

This case study analyzes the $6.8 billion merger between Exelon and Pepco Holdings, which created the largest utility in the United States. The document uses the contentious approval process in the District of Columbia to identify five broader trends in the U.S. power sector: increased utility consolidation to hedge against volatile wholesale markets, disputes over microgrid ownership, the criticality of rate design equity, the rise of mobilized customer constituencies, and the proliferation of state-level power sector transformation proceedings.

A statement by CIEL President Carroll Muffett regarding the announcement of a Climate Action Coalition by US Attorneys General and their investigations into fossil fuel companies, specifically Exxon, for climate deception and fraud.

This fact sheet provides a comprehensive overview of the global offshore wind energy sector as of early 2016, contrasting the established European market with the emerging industry in the United States. It details the technical advantages of offshore wind over onshore wind, current installation capacities, key market players, and the economic and environmental impacts of the transition.

As of 2016, Europe dominated the global offshore wind market, with the UK, Germany, and Denmark leading in installed capacity. The United States, while possessing vast potential (over 4,000 GW), was in the early stages of deployment with its first commercial project at Block Island. The document highlights the technical advantages of offshore wind—such as stronger winds and proximity to coastal population centers—and notes the significant job creation potential in the EU sector.

This report by the Center for International Environmental Law (CIEL) analyzes how the proposed Regulatory Cooperation chapter of the Trans-Atlantic Trade and Investment Partnership (TTIP) agreement could undermine the authority of US states to implement public health and environmental protections. The author argues that the agreement's goals of regulatory convergence and compatibility would effectively create a regulatory ceiling, preventing states from adopting standards more protective than federal minimums, particularly regarding toxic chemicals and pesticides.

This 2013 issue brief by the Environmental and Energy Study Institute examines the funding crisis of the U.S. Highway Trust Fund (HTF), noting that federal fuel taxes have not been adjusted in 20 years. The document analyzes the resulting infrastructure deterioration, the reliance on General Fund transfers to maintain solvency, and various policy options—including inflation indexing, fuel tax increases, and vehicle miles traveled (VMT) fees—to close a $112 billion annual funding gap.
