This fact sheet explains the Advanced Clean Truck (ACT) regulation adopted by California in 2020, which requires original equipment manufacturers (OEMs) of medium- and heavy-duty vehicles to increase the percentage of zero-emissions vehicles (ZEVs) and near-zero-emissions vehicles (NZEVs) in their annual sales from 2024 to 2035.

This guide explains the Advanced Clean Cars II (ACC II) regulation in California, which aims to reduce light-duty vehicle emissions by 50 percent by 2040. The regulation mandates that original equipment manufacturers (OEMs) increase the sale of zero-emission vehicles (ZEVs) and plug-in hybrid electric vehicles (PHEVs), culminating in a requirement that 100 percent of sales be ZEVs or PHEVs by 2035.

This briefing by RMI outlines strategies and policy levers to reduce methane emissions from municipal solid waste (MSW) landfills in the United States. It proposes a two-pronged approach: improving the monitoring and control of existing waste and preventing new methane generation by diverting organic waste from landfills. The document advocates for stronger federal standards from the EPA to scale these reductions and protect adjacent communities.

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 RMI fact sheet explains the technology, benefits, and market opportunities for geothermal heat pumps (also known as ground-source heat pumps) in the United States. It highlights their efficiency in both hot and cold climates, their role in reducing building emissions, and the impact of the Inflation Reduction Act on lowering installation costs.

This fact sheet by RMI explains the concept of embodied carbon in building materials, detailing how it is calculated, strategies for its reduction, and the role of policy and industry in decarbonizing construction.

AFRODAD urges the adoption of the New York Taxpayer and International Debt Crises Protection Act to compel private creditors to participate in debt relief. The organization highlights that 23 African countries face debt distress or high risk, exacerbated by sovereign bonds and global crises including the climate emergency, the COVID-19 pandemic, and the Ukraine-Russia Conflict.

This report by Energy Innovation and RMI evaluates the impact of five key state-level energy policies on greenhouse gas (GHG) emissions across six U.S. states using the Energy Policy Simulator (EPS). The analysis demonstrates that a coordinated policy approach can significantly reduce emissions, create jobs, and improve public health outcomes.

This briefing by RMI outlines the energy affordability crisis in the US, driven by high fossil fuel prices and rising electricity rates, and provides a toolkit of short-term and long-term regulatory solutions for state public utility commissions to reduce the energy burden on vulnerable households.

The Stockholm Environment Institute's 2023 report analyzes emission reduction scenarios for the Genesee-Finger Lakes region. It finds that while a 'high ambition' scenario can meet New York State's 2030 climate targets, none of the analyzed scenarios achieve the 85% reduction required by 2050. Key challenges include significant emissions from dairy cow enteric fermentation and large-scale landfills, while key opportunities lie in grid decarbonization, vehicle electrification, and agricultural manure management.

This report by Energy Innovation provides a guide for state policymakers to leverage the Inflation Reduction Act (IRA) of 2022 to accelerate the transition to clean electricity. It details the mechanics of clean energy tax credits, reinvestment financing for fossil infrastructure, and transmission provisions, while analyzing independent modeling of the IRA's potential to reduce U.S. electricity sector emissions and lower household energy costs by 2030.

This report by RMI examines the shift toward "climate-forward efficiency," which prioritizes energy efficiency, electrification, and demand flexibility specifically to reduce greenhouse gas (GHG) emissions. It analyzes the use of Performance Incentive Mechanisms (PIMs) to align utility business models—which traditionally favor capital investment and sales growth—with state climate goals.

This RMI fact sheet analyzes the Low-Income Home Energy Assistance Program (LIHEAP) in the United States, concluding that federal funding is insufficient to cover the energy costs of all eligible low-income families and that significant numbers of eligible households remain unserved due to barriers like lack of awareness and complex application procedures.

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 fact sheet from RMI argues that electric trucks are currently viable for a significant portion of the market, provided that policy frameworks and grid infrastructure are strengthened to support their adoption.

This guide from RMI outlines the current state and potential for electrifying various trucking sectors in North America, from passenger pickups and delivery vans to medium-duty box trucks and heavy-duty big rigs. It highlights the economic viability of electrification for several segments and the significant greenhouse gas emission reductions possible through the transition.

This guide from RMI explains how local governments can use Community Project Funding (CPF)—a form of discretionary spending available to members of Congress—to finance innovative clean energy and climate resilience projects that might not fit the strict criteria of traditional federal grants.

This report by the International Institute for Sustainable Development (IISD) analyzes the necessity and design of federal just transition legislation in Canada. It evaluates international best practices from 12 jurisdictions to provide a framework for protecting workers and communities during the shift to a low-carbon economy, emphasizing social dialogue, Indigenous partnership, and corporate accountability.

This document provides biographical profiles of speakers associated with the 2022 Sustainable Energy in America Factbook, detailing their professional roles in energy policy, government relations, and sustainability across various organizations.

This briefing summarizes a panel discussion on the climate and environmental justice impacts of plastic production, highlighting the role of the petrochemical industry in greenhouse gas emissions and the necessity of policy shifts toward reuse and extended producer responsibility.
