This report by RMI argues for the establishment of comprehensive indoor air quality (IAQ) guidelines in the United States to protect public health and inform building decarbonization. It examines the health risks of indoor pollutants, compares indoor and outdoor air regulation, reviews international and domestic examples of IAQ guidelines, and outlines how such guidelines can be applied to product safety, building codes, and certifications.

This document provides a collection of case studies and resources intended to help State Energy Offices (SEOs) design and implement home energy rebate programs under the Inflation Reduction Act (IRA). It highlights specific tools, frameworks, and programs that address equity, workforce development, consumer education, and supply chain coordination to optimize residential energy retrofits and electrification.

This guide by RMI explores how Real Estate Investment Trusts (REITs) can leverage their extensive rooftop and parking assets to drive solar development, reducing greenhouse gas emissions while increasing shareholder value. It identifies significant untapped capacity, outlines the financial and regulatory barriers to adoption, and proposes community solar as a viable solution to overcome these challenges.

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 briefing by RMI examines the debate over emissions accounting methods in New York State, specifically focusing on the shift to a 20-year global warming potential (GWP20) timeframe and the inclusion of upstream and biogenic emissions. The author argues that this 'new climate math' increases climate benefits without necessarily increasing costs, as physical emissions remain constant regardless of the accounting timeframe used.

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 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 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.

This report by Energy Innovation analyzes the building sector provisions of the 2022 Inflation Reduction Act (IRA), detailing how rebates, tax credits, and funding for building codes can accelerate decarbonization. It provides a roadmap for federal, state, and local policymakers to implement these incentives, emphasizing the need for complementary regulations—such as updated appliance standards and building codes—to overcome the challenge of slow building stock turnover and meet 2030 climate goals.

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 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 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 briefing discusses how hybrid clean energy systems—combining local renewable resources like solar with baseload resources like geothermal—can address energy and climate injustices in marginalized communities. It highlights the disproportionate impact of extreme heat and aging gas infrastructure on low-income communities of color and evaluates policy interventions and technical models, such as a geothermal pilot in Massachusetts, to improve energy security and resilience.

This report by the Electrifying Canada task force outlines the requirements and barriers to scaling up Canada's clean electricity system to achieve net-zero emissions by 2050. It argues that current utility planning is insufficient to meet the projected demand growth and proposes five catalysts—including regulatory mandates and private investment—to accelerate the transition.

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.

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 fact sheet from RMI outlines the climate, health, and economic advantages of transitioning US buildings from fossil fuels to clean electricity for heating and cooking, arguing that electrification is the only established method to eliminate carbon pollution from residential and commercial appliances.

This policy brief by RMI argues that the United States requires a bold, coordinated national vision for transportation electrification by 2030 to meet climate goals and maintain global industrial competitiveness. It proposes specific targets for EV adoption and infrastructure, alongside a national industrial strategy to retool manufacturing and an aggressive fleet electrification plan.

This report by the Environmental and Energy Study Institute (EESI) provides 30 federal policy recommendations to enhance the climate resilience of U.S. coastal communities. Based on a series of 16 Congressional briefings featuring 42 experts, the document outlines strategies across six themes: community engagement, land use and development, cultural heritage, climate data, disaster preparedness, and financing. It emphasizes the need for policies based on future climate projections, the integration of climate justice, and the prioritization of nature-based solutions over traditional gray infrastructure.

This briefing by Energy Innovation examines the role of offshore wind in achieving zero-emissions climate goals, focusing on cost reductions, technological advancements like floating turbines, and policy recommendations for the United States to scale its capacity.
