Energy Innovation has released version 4.0 of the United States Energy Policy Simulator (EPS), an open-source model updated to incorporate the impacts of the Inflation Reduction Act (IRA) and the Infrastructure Investment and Jobs Act (IIJA). The updated model features a rebuilt electricity sector with hourly dispatch and expanded power plant types to better analyze the financial incentives and emissions trajectories of the U.S. energy system through 2050.

This report by the Climate Policy Initiative explores the concept of "deep green" finance in China, moving beyond the funding of individual sustainable assets to financing the systemic transformation of entire sectors and economies. Using Shanxi and Sichuan provinces as case studies, the author argues that true sustainability requires addressing structural barriers, such as coal dependency and market design, and proposes a framework of four tests and six recommendations to implement transformational green finance.

This fact sheet from the Environmental and Energy Study Institute outlines the timeline and regulatory framework for the U.S. Environmental Protection Agency's (EPA) authority to regulate greenhouse gas (GHG) emissions under the Clean Air Act, detailing specific permitting thresholds and future standards for industrial sources.

This preliminary analysis examines carbon capture and sequestration (CCS) deployment in Norway and Brazil, suggesting that in these cases, CCS has been utilized as a strategic tool for economic competitiveness rather than primarily for climate change mitigation.

This fact sheet by the Environmental and Energy Study Institute details the Obama administration's fiscal year (FY) 2012 budget proposal, focusing on investments in clean technology, energy efficiency, and transportation infrastructure to drive economic growth and climate protection.

This report by the Stockholm Environment Institute and Synapse Energy Economics models the water-energy nexus in the eleven-state Western Electric Coordinating Council (WECC) through 2100. It examines how different electricity generation pathways—ranging from business-as-usual to aggressive carbon and water reductions—impact water consumption, greenhouse gas emissions, and system costs. The analysis concludes that while power plants require water, their total consumption is significantly lower than agricultural and urban use, suggesting the water-energy nexus is a secondary driver of regional water stress compared to other sectors.

A fact sheet from the Environmental and Energy Study Institute detailing the Environmental Protection Agency's (EPA) implementation of greenhouse gas (GHG) permitting standards under the Clean Air Act, focusing on new and modified large power plants and refineries.

Friends of the Earth issued a statement criticizing the Kerry-Boxer draft climate bill, arguing that it contains significant loopholes and insufficient emissions targets to effectively combat climate change.

This research paper evaluates the 'price-gap approach' for measuring fossil fuel subsidies, arguing that while it provides a useful global benchmark, it systematically understates the total magnitude of government support by ignoring transfers that do not affect end-user prices.

This document is a written testimony submitted by the World Resources Institute (WRI) to the U.S. House Select Committee on Energy Independence and Global Warming on September 14, 2007. It argues that carbon dioxide capture and sequestration (CCS) is a critical near-term technology for reducing greenhouse gas emissions from coal, as other low-carbon energy sources are currently unable to offset coal use at the necessary scale. WRI advocates for increased public funding for research, development and demonstration (RD&D) and the implementation of a carbon cap and trade regime, while noting that current cap and trade proposals may not provide high enough carbon prices to offset initial CCS capture costs.

This document is an appendix to a toolkit by RMI that provides a comprehensive set of questions for regulators to use when evaluating how utilities incorporate Inflation Reduction Act (IRA) incentives into their Integrated Resource Plans (IRPs). It aims to help regulators identify cost-saving opportunities and assess the rationale behind utility assumptions regarding clean energy tax credits, hydrogen, carbon capture, and electrification.

This policy brief, produced by the Stockholm Environment Institute in partnership with the 3C initiative, examines the water-energy nexus within the context of a low-carbon transition. It highlights that while low-carbon electricity technologies are essential for reducing greenhouse gas emissions, some may require as much or more water as fossil-fuel generation, potentially limiting their viability in water-stressed regions. The document provides a detailed case study of California to demonstrate how strategic technology choices—such as prioritizing solar photovoltaics over solar thermal and adopting dry-cooling systems—can simultaneously reduce emissions and water demand.

This briefing from the World Resources Institute examines the liability and financial responsibility frameworks applicable to carbon dioxide capture and geological sequestration (CCS), specifically focusing on deep saline formations and depleted oil and gas fields.

This policy brief from the World Resources Institute discusses the role of public perception in the deployment of carbon dioxide capture and sequestration (CCS) and suggests strategies for building long-term public support.

This briefing from the World Resources Institute discusses the role of Carbon Capture and Sequestration (CCS) in mitigating climate change and identifies the primary policy and technical barriers to its deployment.
