This guide provides a decision-support tool for public finance providers to assess the quality of adaptation finance across project, market, and system levels. It defines high-quality adaptation finance as capital deployed efficiently to deliver resilience while moving solutions toward commercial viability or sustaining necessary public services. The tool uses a three-stage qualitative framework—Initial, Progressing, and Transformative—to diagnose strengths and gaps in interventions across grants, debt, equity, and risk transfer tools.

This research paper by the International Institute for Sustainable Development (IISD) analyzes the misalignment of global public finance, noting that in 2024, public support for fossil fuels exceeded USD 1.2 trillion, nearly five times the USD 254 billion provided to clean energy. The report examines fossil fuel subsidies, G20 renewable energy support, state-owned enterprise (SOE) capital expenditure, and international public finance, arguing that governments must shift from blanket subsidies to targeted social protection and clean energy investment to reduce fiscal exposure and energy vulnerability.

This guide from the International Institute for Sustainable Development explains the role and trends of international public finance in the energy sector, specifically focusing on the activities of G20 governments and multilateral development banks (MDBs).

This report by the International Institute for Sustainable Development analyzes India's energy transition through the lens of public finance, focusing on government support, revenues, and the role of state-owned enterprises (SOEs) for fiscal year 2023–2024 (FY 2024).

This research paper by the Climate Policy Initiative (CPI) proposes a quantitative approach to tracking the quality of public climate finance. It builds upon a three-level conceptual framework—project, market, and system levels—to identify practical indicators that can reduce subjectivity in quality judgments and improve coordination among public finance providers.

This briefing by Zero Carbon Analytics, written with Africa Climate Insights, examines the critical shortfall in climate adaptation finance for Africa and developing nations. It argues that public finance must remain the primary driver of adaptation due to the 'less bankable' nature of adaptation projects compared to mitigation and the high debt distress in African economies.

The Global Landscape of Climate Finance 2025 summary handout reports that global climate finance reached a record USD 1.9 trillion in 2023, driven largely by private sector growth. Despite this increase, a significant gap remains between current flows and the investment needed to meet global climate goals, with mitigation finance dominating the landscape while adaptation finance saw a decline in 2023.

This guide provides a structured framework for governments to develop and implement national or subnational fossil fuel subsidy (FFS) phase-out plans. It advocates for a whole-of-government approach to coordinate across ministries and proposes a three-category classification system to prioritize subsidies based on their risk to energy security, social stability, and political feasibility. The framework aims to move governments from general commitments to actionable, time-bound implementation roadmaps.

This report by the International Institute for Sustainable Development evaluates the progress of Clean Energy Transition Partnership (CETP) signatories in 2024, two years after their deadline to end international public finance for fossil fuels. While fossil fuel funding has decreased significantly, the report highlights a failure to redirect those funds toward clean energy at a sufficient scale.

This report by the International Institute for Sustainable Development (IISD) analyzes public financial support for the liquefied natural gas (LNG) sector in British Columbia, arguing that government subsidies shift risks from private investors to the public while ignoring environmental costs and market volatility.

This research paper proposes a three-tiered conceptual framework (project, market, and system levels) to help public climate finance providers move from tracking the quantity of finance to assessing its quality. It defines 'transformational climate finance' as that which induces structural, long-term shifts in markets and systems, and calls for standardized metrics to replace current institution-specific approaches.

This briefing by the International Institute for Sustainable Development (IISD) argues that Canada continues to provide billions in public funds to the fossil fuel industry despite pledges to phase out subsidies. The document outlines five priority areas for reform—tax credits, the Trans Mountain Pipeline, carbon capture and storage, LNG infrastructure, and low-carbon funds—and calls for a comprehensive, transparent inventory of all financial supports to ensure Canada meets its international commitments as the 2025 G7 president.

This research paper by Rashid S. Kaukab analyzes the concerns of developing countries regarding the World Trade Organization (WTO) moratorium on customs duties on electronic transmissions. The author argues that the moratorium disproportionately benefits developed nations due to the global digital divide and restricts the fiscal and industrial policy space of developing economies.

In 2023, G20 governments provided at least USD 168 billion in public financial support for renewable power, a figure that is less than one third of the USD 535 billion provided in fossil fuel subsidies that same year.

This report by the International Institute for Sustainable Development evaluates the progress of the Clean Energy Transition Partnership (CETP) signatories in shifting international public finance from fossil fuels to clean energy, finding that while fossil fuel funding has decreased significantly, clean energy investment has not increased at a commensurate scale.

This report by the International Institute for Sustainable Development analyzes the scale of Canadian public financing for the fossil fuel sector and provides recommendations for a comprehensive policy to eliminate such financing to support the energy transition.

This report by the International Institute for Sustainable Development (IISD) argues that Canada must end its domestic public financing for fossil fuels to align with the Paris Agreement and its own climate commitments. It highlights a significant disparity between the billions provided to the fossil fuel sector and the relatively small amounts allocated to domestic renewable energy, while providing a detailed framework for a comprehensive phase-out policy.

This case study describes France's implementation of a 'Green Budget' process to align public finance with the Paris Agreement and net-zero goals, utilizing a specific rating methodology for state expenditures and setting minimum environmental thresholds for recovery funding.

This report finds that while CETP signatories have successfully restricted fossil fuel finance, they have failed to fully prioritize clean energy finance. Despite a potential for USD 28 billion in annual shifts, only USD 5.2 billion was moved into clean energy in the first year. The report notes that no high-income signatories have published fully aligned policies and recommends the adoption of quantitative targets and grant-based instruments to support a just energy transition.

This briefing from the International Institute for Sustainable Development analyzes global public financial flows to fossil fuels and clean energy in 2022, highlighting a record high in support for fossil fuels and a gap between climate commitments and implementation ahead of COP 28.
