A statement by Tony de Brum (Minister of Foreign Affairs of the Republic of the Marshall Islands) and Maria de Fátima Monteiro Jardim (Minister of Environment of Angola) urging G20 leaders meeting in Antalya, Turkey, to drive ambition for the Paris Climate Change Conference.

This briefing by the Climate Bonds Initiative argues that natural gas is not a viable transition fuel due to significant methane leakage across its supply chain, which makes its climate impact comparable to coal. It highlights Japan's vulnerability due to its high reliance on LNG imports and proposes several policy measures to accelerate decarbonization.

This guide by the Climate Bonds Initiative provides a framework for issuing certified green bonds in the transport sector, with a specific focus on the Brazilian market. It outlines the Climate Bonds Standard, the certification process, and the technical eligibility criteria for various transport assets to ensure alignment with the goal of limiting global temperature rise to 1.5 degrees Celsius.

This report by the Climate Bonds Initiative analyzes how sustainable finance taxonomies integrate mechanisms to support the transition of high-emission sectors toward net-zero emissions by 2050. It identifies six specific 'Taxonomy Transition Mechanisms' used to define and evaluate the credibility of transition activities, providing a framework for taxonomy designers, investors, and market professionals to ensure robust and science-based decarbonization pathways.

This annexure provides a detailed source-sink mapping and cluster analysis for the decarbonization of India's steel sector using Carbon Capture, Utilization, and Storage (CCUS). It identifies specific industrial clusters in the eastern region, estimates their CO2 emissions and storage requirements, and maps available storage capacities in saline aquifers and coal fields. Additionally, it outlines global CCUS operational projects and compares policy frameworks in the US, EU, UK, and China.

The Financing Steel Decarbonization (FSD) instrument is designed to mobilize private finance for low-carbon technologies in the steel sector, specifically targeting technology adopters and providing technical assistance. It consists of two entities: the Steel Decarbonization Financing Facility (SDF), a blended debt fund, and the Steel Decarbonization Initiative (SDI), a service provider for project implementation.

The Global Renewable Independent Power Supplier (Grips) is a proposed renewable energy service company designed to mobilize private-sector funding for hybrid energy plants in remote areas of developing countries, specifically targeting industrial anchor clients currently dependent on diesel generators.

This fact sheet by the Climate Policy Initiative explores how a proposed California green bank could accelerate the decarbonization of the transportation sector, which accounts for approximately 40 percent of the state's greenhouse gas (GHG) emissions. The document identifies specific financial and risk-bearing interventions across four subsectors: passenger vehicles, alternative fuel vehicle infrastructure, goods movement, and regional planning.

This July 2012 fact sheet from the Environmental and Energy Study Institute describes the technology, applications, and economic landscape of small-scale wind power in the United States. It details the differences between horizontal and vertical axis turbines, the shift toward grid-connected systems, and the role of federal and state incentives in driving market growth.

The 2026 Global Electricity Review by Ember reports that record solar energy growth in 2025 met the entirety of new global electricity demand, halting the increase in fossil fuel generation for the first time since 2020. For the first time in the modern era, renewable energy sources collectively surpassed coal, accounting for over one-third of global electricity generation.

This policy brief by Energy Innovation outlines a pathway for California to achieve 85 percent carbon-free electricity by 2030. Based on technical analysis by Telos Energy and GridLab, the document argues that this target is reliably achievable even under extreme stressors. It provides a set of 'no-regrets' policy recommendations focused on diversifying clean energy deployment, phasing out natural gas plants—particularly in disadvantaged communities—leveraging demand-side resources, and improving regional coordination across Western states.

This report examines the need for U.S. electric utility business models and regulatory frameworks to evolve to support a high-penetration renewable energy future. It proposes a spectrum of utility roles—ranging from minimal involvement to becoming comprehensive energy services providers—and suggests shifting from traditional cost-of-service regulation toward performance-based models like the UK's RIIO to align utility incentives with societal climate and efficiency goals.

This briefing presents preliminary results from the California Energy Policy Simulator (EPS) regarding a scenario where California reduces greenhouse gas emissions by 55 percent below 1990 levels by 2030. The analysis indicates that while such a target would require an energy and industrial transition of "unprecedented speed and scope," it is achievable without new technologies and would result in significant economic gains, job growth, and public health improvements.

This fact sheet by Energy Innovation analyzes the gap between the emissions reductions projected from the Inflation Reduction Act (IRA) and the United States' 2030 Nationally Determined Contribution (NDC) target. Using the U.S. Energy Policy Simulator (EPS), the document identifies additional policy measures across electricity, industry, transportation, and buildings necessary to reach the NDC goal.

This fact sheet summarizes a study by Energy Innovation on the reliability of accelerated clean electricity portfolios in California, specifically testing an 85% clean electricity target for 2030. Using a production cost model (PLEXOS) to stress-test three portfolios against variables such as low hydro, reduced gas availability, and limited imports, the study concludes that reaching this target is feasible and reliable across most weather years and stress conditions.

This fact sheet from Energy Innovation outlines how the Inflation Reduction Act (IRA) transforms clean energy economics in the United States and provides a roadmap for state-level policymakers to maximize these benefits. It argues that while the IRA provides significant incentives to reduce greenhouse gas emissions and lower costs, state action is required to realize this potential.

This fact sheet from Energy Innovation outlines how the Inflation Reduction Act (IRA) provides foundational support for decarbonizing the United States building sector through rebates, tax credits, and funding for building codes, while emphasizing the need for complementary state, local, and Tribal government actions to ensure successful implementation.

This fact sheet from Energy Innovation outlines the challenges energy regulators face due to the uncertainty surrounding the development of the low-emissions hydrogen industry. It argues that regulators must adopt a proactive, holistic approach—looking beyond their immediate jurisdictional purview to include policy, emissions accounting, air pollution, and water usage—to ensure energy affordability, reliability, and safety while avoiding stranded assets.

This report by Energy Innovation argues that the traditional electric utility business model in the United States is facing a 'death spiral' due to technological advances, declining energy demand, and climate regulations. The author proposes a shift toward 'performance-based regulation,' where utilities are rewarded for achieving goals in reliability, affordability, and environmental performance rather than for the volume of electricity sold.

This report proposes the creation of an "energy park" in Pueblo, Colorado, as an economic development strategy to replace the retiring Comanche coal plant. The strategy involves a diversified portfolio of clean energy resources and "flexible" industrial technologies to maintain tax revenue and grid reliability while reducing costs for electricity customers.
