The policy brief highlights the critical role of local governments in Africa and the Global South as implementers of climate adaptation, mitigation, and biodiversity goals. It identifies systemic barriers—including severe finance gaps, technical capacity constraints, and data deficiencies—that hinder municipal action. The authors recommend that South Africa's 2025 G20 presidency establish a multi-level climate governance declaration, a dedicated local climate action forum, and a specialized finance access facility to empower subnational governments as equal partners in global climate governance.

African cities face extreme climate vulnerability, with 83% rated at 'extreme risk', yet they are largely bypassed by the global climate financial architecture. The document highlights that while cities generate 80% of global GDP and are first responders in disasters, they are not parties to international conventions like the UNFCCC. It urges cities to conduct comprehensive vulnerability assessments—including non-economic loss and damage—and to leverage city networks and multi-level governance to access the Fund for responding to Loss and Damage (FRLD), the Warsaw International Mechanism, and the Santiago Network. The brief recommends that national governments integrate urban loss and damage into Nationally Determined Contributions (NDCs) and National Adaptation Plans (NAPs) to improve funding access and implementation.

The CCFLA and Urban-Act National Assessment Tool provides a framework for national governments to evaluate the regulatory, financial, and institutional conditions that affect urban climate finance. The tool consists of 64 dimensions across four categories: Climate Policy, Budget and Finance, Climate Data, and Vertical and Horizontal Coordination. It aims to identify strengths and gaps in national frameworks to facilitate recommendations for improving subnational access to finance, having been piloted in India and Indonesia.

The document highlights the critical need for effective water governance in the Mediterranean to ensure water security and avoid conflict. It notes that current efforts to create a regional framework are hindered by a proliferation of independent initiatives and advocates for context-specific policies based on multi-level governance perspectives.

The report examines vertical integration in National Adaptation Plans (NAPs), highlighting the roles of subnational governments and non-governmental actors. Based on an analysis of 45 multisectoral NAPs, it finds that while most countries recognize subnational roles in planning and implementation, gaps remain in monitoring, evaluation, and learning (MEL) and stable financial flows to local levels. It provides recommendations for national governments, subnational authorities, development partners, and funding bodies to strengthen multi-level coordination and capacity.

The Peer Learning Summit (PLS) convened representatives from 10 countries to exchange knowledge on vertical integration in the National Adaptation Plan (NAP) process. The workshop focused on five interdependent areas: coordination mechanisms with sub-national governments, capacity strengthening, engagement with the local private sector, engagement with civil society organizations (CSOs), and financial flows to sub-national levels. Key discussions highlighted the necessity of long-term monitoring, evaluation, and learning (MEL) systems to track progress across governance levels and the importance of gender-responsive and socially inclusive (GESI) approaches. Participating countries, including Kenya, Ghana, and Tuvalu, shared specific milestones and challenges, such as limited local funding and technical capacity gaps. The event concluded with countries identifying actionable next steps for their respective NAP processes through June 2024.

The report assesses the progress of SDG localization across 28 global case studies, highlighting a significant gap between high-level commitment and practical local implementation. Key findings indicate that while some 'SDG champions' like New York City lead in data analysis and engagement, many regions struggle with weak institutional governance, a lack of systematic analysis of SDG interlinkages (synergies and trade-offs), and limited financial resources. The COVID-19 pandemic is noted as a major setback that reallocated budgets toward healthcare, though it also created opportunities for green recovery. The study emphasizes the need for better evidence-based local data, increased participation of local actors in international forums, and the use of Voluntary Local Reviews (VLRs) to enhance accountability.

The report examines how secondary cities in the Global South navigate sustainability transitions using a multi-level governance framework. Through eight case studies, it analyzes the roles of national, provincial, and local governments, private sector actors, and community-based organizations. The findings highlight that while disasters often trigger local action, a lack of financial autonomy and institutional coordination frequently hinders the scaling of pilot projects. The report argues for a shift from purely participative to collaborative governance to improve inclusivity and sustainability outcomes.

The document argues that while the technology to limit global warming to 1.5°C exists, deployment is hindered by nationalist politics, private sector competitiveness concerns, and capacity constraints in developing nations. It emphasizes that rapid decarbonisation must be balanced with social and economic development to avoid exacerbating inequities and undermining public support.

The document argues that while the 1.5°C target is technically achievable, it is hindered by a lack of political will, insufficient institutional capacity in developing nations, and tensions between rapid decarbonisation and sustainable development goals. It highlights a significant investment gap, noting that the energy sector alone requires an additional $458 billion annually through 2030. The authors suggest that the traditional consensus-based international cooperation model is insufficient and advocate for 'coalitions of the willing' involving non-state actors and philanthropic support to build capacity in disadvantaged regions.

The report analyzes ten CDKN initiatives in India, Indonesia, Nepal, and Pakistan to identify effective design pathways for scaling climate compatible development. It distinguishes between research-led, hybrid, and action-led pathways, concluding that longer-term, action-oriented approaches are most successful in embedding new practices across local, provincial, and national scales. The authors propose several design principles, including early action, adaptive management, and strategic knowledge brokering, to navigate the complex multi-level governance required for climate resilience and low-carbon transitions.

The paper argues that while the water-energy-food nexus approach is popular for identifying resource interdependencies, its treatment of governance is superficial and overly technical. By reviewing the literature through risk, economic rationality, and political economy perspectives, the authors identify three primary gaps: a lack of understanding regarding the conditions for cross-sector collaboration, a neglect of multi-level governance dynamics beyond horizontal interactions, and a failure to account for the political and cognitive factors that determine policy change. The authors suggest that the nexus community must integrate insights from integrative environmental governance theory to move beyond administrative coordination and address the power relations and norms that actually drive decision-making.

The document advocates for multi-level governance in the Caribbean, moving away from 'top-down' adaptation. It highlights that effective climate resilience requires coordinating local networks, conducting community-based vulnerability and adaptive capacity assessments, and linking these local actions to regional and national decision-making processes.

The document argues that effective climate adaptation in the Caribbean requires multi-level governance that integrates local actor networks, community-based vulnerability assessments, and adaptive capacity measurements to link local actions with national decision-making.

The policy brief examines the mismatch between the 'top-down' institutional architecture of the UNFCCC and the critical role subnational governments play in implementing climate mitigation and adaptation. It highlights how rapid global urbanisation increases the importance of cities, yet these entities often lack the legal mandate, finance, and direct access to international negotiating tables. The author discusses the role of transnational actors like ICLEI and C40 in bridging this gap and recommends moving toward a 'co-production' model of governance between national and subnational levels.

The CDKN-ICLEI First Learning Workshop in Quito, Ecuador, brought together 51 participants from 16 projects to identify enablers and barriers to sub-national climate compatible development (CCD). The workshop focused on moving from planning to implementation, resulting in a revised set of assumptions about effective CCD and the identification of critical knowledge gaps in planning, scaling, and conceptualisation. These outcomes informed seven core learning questions that project partners will address through the creation of 'Inside Stories'—reflective, evidence-based analyses of their learning processes. Regional discussions highlighted that in Asia, CCD is often framed as 'climate-smart' or 'climate-friendly' and requires strong links to poverty alleviation and gender issues, while in Latin America and the Caribbean, local framing and political will are seen as key drivers for sustainability.

The document analyzes climate adaptation in Jamaica, focusing on the Whitehouse region. It highlights the central role of government agencies in adaptation design, the importance of social networks and co-management in fisheries, and the significant barriers to local adaptive capacity, including a lack of financial capital and insurance.

The paper examines the slow progress of sanitation coverage in Sub-Saharan Africa, specifically in Rwanda, Uganda, Tanzania, and Burundi. It identifies a critical disconnect between macro-level policies and micro-level household implementation, driven by institutional inertia and path dependency. The authors argue that sustainable progress requires moving beyond supply-driven subsidies toward demand-driven strategies, private sector involvement, and a better understanding of informal norms and multi-level actor interactions.

The document argues that subnational governments are essential for implementing sustainable development policies because they are closest to citizens' needs and can foster grassroots innovation. It emphasizes the need for 'vertical coordination'—the linking of local, subnational, national, and supranational levels—to ensure policy coherence. Using empirical research, the author identifies good practice examples in Europe (such as Tyrol, Austria) and other regions (such as Bhutan), while noting that many regions lack systematic links to national strategies due to political independence or administrative bottlenecks. The briefing recommends a 'metagovernance' approach that mixes hierarchical, market, and network styles to better integrate sustainable development across all levels of government.

The document examines the impact of governance structures on urban climate action in Italy and Spain, comparing a top-down approach in Spain with a more reactive, bottom-up approach in Italy. It finds that while national and regional frameworks often fail to sufficiently support cities, transnational networks like the Covenant of Mayors (CoM) are pivotal in driving the development of local mitigation plans. In Spain, the Central Government's collaborative efforts were partially diluted by regional 'gatekeepers', whereas in Italy, the lack of national guidance led proactive cities to rely on networks and EU projects. Both countries show a strong focus on mitigation (energy and transport) but a significant deficiency in local adaptation planning.
