This briefing by Zero Carbon Analytics examines the causal link between fossil fuel emissions and the increasing frequency and intensity of extreme weather events. It details the role of 'Carbon Majors' in global emissions, the financial disparity between industry profits and climate damages, and the growing use of litigation to hold these companies accountable. The document argues that a managed phase-out of fossil fuels, through both supply and demand reductions, is essential to limit global warming to 1.5 degrees Celsius.

This guide by RMI introduces Performance-Based Regulation (PBR) as a regulatory approach for electric utilities designed to align utility incentives with customer and societal interests. It contrasts PBR with traditional cost-of-service regulation (COSR), which the document argues creates perverse incentives such as 'gold plating' and 'capex bias' that hinder the clean energy transition. The guide details various PBR tools—including revenue decoupling, multi-year rate plans, and performance incentive mechanisms—and provides a framework for moving from incremental to comprehensive PBR reform.

In May 2024, the US Departments of Agriculture (USDA) and Housing and Urban Development (HUD) updated minimum energy standards for new construction, requiring new covered buildings under four stories to comply with the 2021 International Energy Conservation Code (2021 IECC) and taller buildings to meet ASHRAE/ANSI Standard 90.1-2019. These updates, combined with 45L tax credits from the Inflation Reduction Act (IRA), make high-performance multifamily housing financially viable, particularly for all-electric constructions and those in specific climate zones.

The report examines 'equity PIMs' as a regulatory tool to incentivize utilities to improve energy affordability and service for underserved communities. It highlights that while several US states have adopted these mechanisms to target energy efficiency and reduce disconnections, they are most effective when paired with broader systemic reforms, reporting metrics, and direct assistance programs.

This fact sheet from the Environmental and Energy Study Institute (EESI) provides data on the growth and distribution of climate-related jobs in the United States as of 2022, highlighting sectors such as energy efficiency, renewable energy, clean vehicles, and adaptation and resilience.

This document is the 2024 IRS Form 990 'Return of Organization Exempt From Income Tax' for the Stockholm Environment Institute (SEI) U.S., Inc., a 501(c)(3) non-profit organization based in Somerville, Massachusetts. The filing details the organization's financial activities, governance, and program accomplishments for the 2024 calendar year, focusing on its mission to provide research and decision-support tools for sustainable development, energy, water, and climate policy.

This case study examines how the Allston Brighton Community Development Corporation (CDC), a nonprofit affordable housing owner in Boston, is implementing deep energy retrofits (DER) across its portfolio to eliminate fossil fuel combustion and reduce energy consumption.

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.

The Agricultural Management Assistance (AMA) program is a USDA initiative designed to help agricultural producers manage financial risk through conservation practices, crop diversification, and marketing assistance. It is available in 16 specific US states where crop insurance rates are low, with permanent mandatory funding of $10 million per fiscal year.

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.
