This report provides a comparative analysis of global electricity tariff-setting methodologies, focusing on the process of determining revenue requirements and conducting Cost of Supply (CoS) studies. It examines various regulatory models—including rate-of-return, incentive-based, performance-based, and market-based pricing—and evaluates their effectiveness in balancing financial sustainability for utilities with affordability for consumers. The document concludes with specific recommendations for South Africa to modernize its tariff structures and revenue determination processes as it transitions toward a wholesale electricity market.

This report by Zero Carbon Analytics examines the systemic lack of transparency and consistency in reporting oil-related accidents across the Americas. It highlights that while Brazil, Canada, and the United States are the only countries with regularly updated open databases, these records still contain significant gaps regarding ecological damage, human casualties, and responsible parties. The document emphasizes that this data scarcity obscures the true gravity of industrial risks, particularly in ecologically sensitive regions like the Amazon.

This briefing from the Inter-American Institute for Global Change Research (IAI) provides a financial update for the period of July to October 2025, detailing party contributions and operational expenditures for the 2025-2026 fiscal year.

This report by Ember, developed for the Global Offshore Wind Alliance (GOWA), provides a comprehensive analysis of global offshore wind targets across national, subnational, and regional levels. It examines current ambitions, deployment projections for 2030, and the potential for expansion in countries without existing targets, while highlighting the gap between political ambitions and projected delivery.

This fact sheet describes green bonds as fixed-income instruments earmarked for environmental projects, highlighting that energy and buildings receive the largest share of recent allocations (~30% each). It details the roles of institutional investors and MDBs—such as the World Bank and EIB—and outlines the technical requirements, costs (including a typical greenium of 2–5 bps), and timelines for issuing these instruments.

This report by the Centro de Movilidad Sostenible monitors the impact of the Energy Efficiency Law's light vehicle standards in Chile during 2024 and 2025. It analyzes corporate fuel economy targets, the growth of plug-in vehicles, and the resulting reductions in fuel demand and CO2 emissions.

This report by the Climate Policy Initiative (CPI) provides a strategic roadmap to increase climate finance for livestock systems in Latin America and the Caribbean (LAC). It identifies a massive funding gap, analyzes investment barriers—particularly for smallholders—and proposes a combination of blended finance strategies and public policy reforms to attract private capital and transition the sector toward sustainable practices.

This report by Ember analyzes the challenge of solar and wind energy curtailment in Chile, where renewable generation has grown rapidly but is hindered by limited transmission and storage capacity. It proposes a phased package of policy and technical measures—including battery storage, dynamic line rating, and demand response markets—to reduce waste and maximize the potential of Chile's clean energy resources over the next five years.

This policy brief by Ember analyzes the challenge of renewable energy curtailment (vertimientos) in Chile, where solar and wind generation have grown rapidly but are hindered by transmission bottlenecks and a lack of system flexibility. The document proposes a 'Clean Flexibility Kit' of short, medium, and long-term measures—including battery storage, dynamic line rating, and demand response markets—to maximize the use of clean energy and reduce economic losses for investors.

The China Energy Transition Review 2025 by Ember analyzes China's rapid shift toward clean energy and electrification, detailing how its domestic policies and manufacturing scale are driving down global costs and pushing global fossil fuel demand toward a structural decline.

This briefing, prepared for the 11th session of the open-ended intergovernmental working group (OEIGWG), advocates for the explicit inclusion of the right to a clean, healthy, and sustainable environment (RtHE) within a proposed international legally binding instrument (LBI) to regulate transnational corporations and business enterprises.

This briefing paper argues for the adoption of a United Nations legally binding instrument (LBI) to regulate transnational corporations as a structural lever for environmental justice. It highlights the failure of voluntary frameworks to ensure corporate accountability for ecological destruction and human rights abuses, proposing that a binding treaty would operationalize the right to a clean, healthy, and sustainable environment through mandatory due diligence, extraterritorial jurisdiction, and effective remediation.

This guide explains Nationally Determined Contributions (NDCs) as the primary vehicle for countries to implement the Paris Agreement's goals. It highlights a critical gap between current commitments (leading to 2.6-3.1°C warming) and the 1.5°C target, urging more ambitious 2025 submissions. The document details the need for $4.5 trillion in funding for developing nations and outlines the NCQG's goal to mobilize $300 billion annually by 2035.

The 33rd meeting of the Conference of the Parties (CoP-33) of the Inter-American Institute for Global Change Research (IAI) took place in Asunción, Paraguay, on May 29-30, 2025. The meeting focused on strengthening regional scientific collaboration, advancing science diplomacy, and enhancing climate resilience across the Americas. Key outcomes included the adoption of 18 decisions, the creation of an Indigenous Peoples Advisory Committee (IPAC), the approval of an updated Open Science and Open Data Policy, and the admission of three new Associate members: the World Meteorological Organization (WMO), the American Geophysical Union (AGU), and the Venezuelan Institute for Scientific Research (IVIC).

The report details the 59th meeting of the Executive Council of the Inter-American Institute for Global Change Research (IAI), held on May 28, 2025, in Asunción, Paraguay. The meeting focused on approving the 2025–2026 operating budget, addressing funding deficits for regional research initiatives, and proposing a shift in how member states designate national representatives to ensure institutional continuity.

This guide by the Climate Bonds Initiative provides a framework for investors to evaluate and engage with sovereign transition plans. It outlines key elements of credible planning, including science-based targets, detailed investment and policy roadmaps, and robust governance and transparency measures, aiming to help investors assess the long-term sustainability of sovereign asset exposures.

This report uses the Sustainable Asset Valuation (SAVi) methodology to evaluate the economic, social, and environmental benefits of restoring 579 hectares of the Rocuant–Andalién coastal wetland system in Chile's Biobío region. The analysis demonstrates that nature-based infrastructure (NBI) is economically viable across all modelled scenarios, providing significant returns through avoided flood damage, carbon storage, and social value.

This report documents a side event held during the 33rd Conference of the Parties (CoP-33) in Asunción, Paraguay, on May 28, 2025. Co-organized by the Inter-American Institute for Global Change Research (IAI) and other regional and international bodies, the event focused on formulating recommendations for drought management, improving early warning systems (EWS), and enhancing science-policy integration to support vulnerable sectors in Paraguay and the wider Americas.

This report documents a hybrid event held on May 28, 2025, in Asunción, Paraguay, organized by the Inter-American Institute for Global Change Research (IAI) and partners.
