An analysis of 14 major economies outside the traditional UNFCCC contributors reveals that they provided approximately $102 billion in voluntary climate finance from 2013 to 2023. The study highlights a shift toward a multipolar finance reality, where emerging markets and developing economies (EMDEs) are increasingly active, though their contributions remain fragmented in official reporting. The report emphasizes the need for inclusive reporting frameworks and the scaling of triangular partnerships and de-risking mechanisms to mobilize further private capital to meet global climate goals.

The paper assesses climate finance provided by 14 non-Annex II countries, finding they contributed $102.38 billion between 2013 and 2023. While China is the largest contributor, other nations show a strong preference for adaptation. The study emphasizes the need to standardize this voluntary data to support the Baku to Belém (B2B) Roadmap and a multipolar financial system.

The report argues that public development banks (PDBs)—including national, regional, and multilateral institutions—are uniquely positioned to overcome structural and market barriers to climate risk insurance in EMDEs. It identifies key barriers such as data gaps, underdeveloped local capital bases, and fragmented regulatory frameworks. The document proposes a tiered approach where National Development Banks (NDBs) focus on local market development and project pipelines, Regional Development Banks (RDBs) coordinate risk pooling and shared data infrastructure, and Multilateral Development Banks (MDBs) provide catalytic capital and credit enhancement. Key recommendations include the use of targeted premium subsidies with sunset clauses, the bundling of insurance with loans, and the creation of regulatory sandboxes to foster innovation in parametric insurance.

The document analyzes a structural contraction in Official Development Assistance (ODA) and a persistent under-allocation of climate finance toward adaptation. It argues that while the sector possesses the foresight to predict these trends, institutional barriers prevent this knowledge from translating into action. The paper highlights the failure of blended finance to scale in high-exposure contexts, the inability of alternative donors like China and Gulf states to replace Western ODA, and emerging risks such as the centralization of risk analytics and sovereign debt traps.

International public finance for energy projects by G20 governments and multilateral development banks exceeds USD 100 billion annually. While funding for fossil fuels dropped from USD 151 billion in 2016 to USD 37 billion in 2024, clean energy finance has grown more slowly, reaching USD 47 billion in 2024. The Clean Energy Transition Partnership (CETP) has significantly reduced fossil fuel finance among its members, though the redirection of these funds toward clean energy remains limited.

The report analyzes how high debt-service obligations and fossil fuel reliance create a structural trap for Global South nations, where fiscal pressures force governments to prioritize short-term liquidity and fossil fuel extraction over long-term renewable energy transitions. Through case studies of Colombia, Egypt, Guyana, Jordan, and Sri Lanka, it demonstrates that this nexus is systemic, often reinforced by the conditionalities of International Financial Institutions (IFIs) and the interests of multinational corporations. The document advocates for comprehensive debt cancellation, the end of fossil fuel finance, and a global transition framework based on 'extraction equity' to dismantle these structural barriers.

The Kuala Lumpur Declaration demands that developed countries fulfill their climate debt through grant-based finance, including an estimated USD 5.1–6.8 trillion by 2030. It advocates for a global Fossil Fuel Treaty, the rejection of 'false solutions' like carbon removal and nuclear power, and the dismantling of restrictive intellectual property regimes to accelerate technology transfer. The declaration further calls for tripling adaptation finance by 2035 and scaling the Fund for Responding to Loss and Damage to hundreds of billions of dollars annually.

The 12th Meeting of the San Giorgio Group (SGG12) focused on moving climate finance from ideas to large-scale delivery, emphasizing system coherence and country-level impact. The group highlighted that annual climate finance now exceeds USD 2 trillion, driven by renewable energy and transport electrification. Key priorities include reforming Multilateral Development Banks (MDBs), scaling guarantees and catalytic equity, and addressing the high cost of capital in developing countries. The agenda also calls for 'radical localism' to center people in the climate narrative and suggests leveraging artificial intelligence and underutilized public financing institutions, such as export credit agencies, to accelerate the energy transition.

The statement calls for COP30 in Belem to establish an action plan for a just transition to 100% renewable energy, specifically targeting the reform of multilateral development banks (MDBs). It argues that current MDB models prioritise private profit and increase debt in the Global South, citing examples of harmful green hydrogen and hydropower projects. The authors propose three shifts: an immediate end to fossil fuel and 'false solution' finance, the provision of grants instead of debt-creating instruments, and a move toward small-scale, community-owned renewable energy projects to ensure energy sovereignty.

The document evaluates the first decade of the Paris Agreement, arguing that climate finance delivery has been characterized by "incremental promises, contentious negotiations, evolving priorities and an erosion of trust amongst Parties." It highlights a significant investment deficit in Africa, where the region receives only 3% of global climate finance flows despite its high vulnerability. The brief critiques the delayed and contested achievement of the US$100 billion annual goal, the underfunding of adaptation and loss and damage, and the over-reliance on debt-creating loans over grants. It calls for a shift toward public-led, concessional finance and systemic reforms to the global financial architecture to ensure equity and transparency ahead of COP30.

The document highlights a critical adaptation finance gap in Africa, noting that the continent requires between $187–359 billion annually but faces an 80% shortfall in adaptation investment. It identifies the South African G20 presidency as a strategic opportunity to shift climate finance from debt-creating loans to grants and concessional funding. Key recommendations include scaling locally led adaptation, implementing debt-for-climate swaps, and reforming Multilateral Development Banks (MDBs) to ensure at least 50% of climate finance for African Least Developed Countries is provided as grants or highly concessional finance.

The briefing criticizes multilateral development banks (MDBs) for continuing to fund large-scale, centralized energy projects that the authors categorize as 'false solutions,' such as nuclear, carbon capture, and fossil gas. It argues these investments undermine equity and delay the transition to sustainable energy. Using case studies from Africa and Asia, the document recommends that MDBs prioritize decentralized renewable energy, reform climate finance frameworks, and ensure the Free, Prior, and Informed Consent of Indigenous peoples.

The G20 has transitioned from a narrow focus on financial stability (2005–2008) to an integrated governance model where energy security, climate action, and sustainable development are central. Key milestones include the 2009 Pittsburgh Summit's first mention of clean energy, the 2015 first Energy Ministers' Meeting, and the recent sequence of Global South presidencies (Indonesia, India, Brazil, South Africa) that have shifted the narrative toward equity, just transitions, and the reform of the international financial architecture. South Africa's 2025 Presidency specifically champions African interconnectivity, critical minerals sovereignty, and debt sustainability to enable a just energy transition.

The document examines how Brazil and South Africa use carbon pricing, green bonds, green taxonomies, and central bank regulations to fund their transitions to net zero by 2050. It highlights the inadequacy of current international climate finance, noting that developing countries pay significantly more for multilateral development bank finance and that most climate funding arrives as loans rather than grants. The brief details South Africa's carbon tax and Just Energy Transition Partnership (JETP), and Brazil's voluntary carbon market and sovereign sustainable bonds. It argues that BRICS nations should use peer learning to scale these tools and collectively advocate for the restructuring of the World Bank and IMF to ensure more affordable and equitable finance for the Global South.

The Clean Air Task Force urges the Asian Development Bank (ADB) to remove its funding ban on nuclear energy to help Asia-Pacific economies meet rising energy demands with clean, firm power. The document highlights that while countries like China and South Korea have successfully used nuclear energy for industrialization, other emerging economies in the region have failed to implement programs due to financing and expertise gaps. It specifically identifies the Ninh Thuận projects in Vietnam and the Bataan Nuclear Power Plant in the Philippines as immediate opportunities for ADB intervention. The author recommends that ADB lift its ban, build internal expertise, create dedicated funds for large and small modular reactors, and prioritize risk-sharing with private and government investors.

The document argues that G20 climate finance often prioritizes private profit over public welfare, trapping vulnerable nations in debt through loan-based funding and 'de-risking' strategies. It calls for a shift toward grant-based funding and public investment based on the 'polluter pays' principle to ensure a just energy transition.

The report analyzes the complementary roles of VCEFs, MDBs, and NDBs in scaling climate finance, highlighting the potential for financial instruments like guarantees and catalytic equity to mobilize private investment. It identifies systemic barriers—such as complex accreditation and slow approval processes—and proposes a roadmap for non-financial collaboration through country platforms, technical assistance, and the creation of enabling policy environments. The document provides specific recommendations for the G20 Sustainable Finance Working Group to improve interoperability and leverage NDBs' local expertise to bridge the investment gap, particularly for adaptation in low-income countries.

The report analyzes the complementary roles of VCEFs, MDBs, and NDBs in the climate finance architecture, focusing on financial instruments like guarantees, equity, and local currency lending. It identifies systemic barriers such as complex accreditation and slow approval processes and proposes a framework for non-financial collaboration through country platforms, technical assistance, and the creation of enabling policy environments. The document provides a set of short- and mid-term recommendations to harmonize metrics, simplify due diligence, and unlock the potential of NDBs to increase the flow of climate finance to emerging markets and developing economies.

The document argues that African countries face a precarious development finance landscape due to declining official development assistance (ODA) and a market bias known as the 'Africa premium'. It proposes that South Africa use its G20 presidency to advocate for a technical committee on financing barriers, host a Global Sovereign Debt Roundtable meeting on restructuring, facilitate dialogue with the Alliance of African Multilateral Financial Institutions, and coordinate with international conferences to promote a more equitable financial system.

The 'Banking on Renewables' report critiques the current funding models of Multilateral Development Banks (MDBs), arguing that the rush to increase renewable energy capacity often leads to 'green extractivism' and human rights violations. It proposes three core criteria for public funding: financing a total transition to 100% renewables (excluding 'false solutions' like CCUS), ensuring democratic and decentralized energy systems, and centering people and the planet. Through case studies in India, Kenya, Rwanda, Tanzania, and Indonesia, the report contrasts large-scale projects that displace communities with community-led initiatives that improve local livelihoods. It concludes with a ten-point action plan urging MDBs to increase grants over loans, adopt a strict renewable energy taxonomy, and mandate Free, Prior and Informed Consent (FPIC) for all projects.
