This report examines how Ecosystem Service Valuation (ESV) can scale finance for Nature-based Solutions (NbS). By revealing the distribution of socio-economic benefits and costs across stakeholders, ESV provides a standardised framework to inform financial mechanisms and structure effective public-private partnerships.

This learning note explores how an ecosystem approach to infrastructure financing can mobilise capital in low- and middle-income countries. It highlights the importance of early finance engagement, de-risking mechanisms, and integrated partnerships to transform technically sound projects into commercially viable investments.

This report analyses the integration of climate change considerations into environmental impact assessment (EIA) regimes across 20 economies in Latin America and Asia. It evaluates legislative frameworks and climate litigation trends, recommending stronger statutory requirements, detailed technical guidance, and comprehensive assessments of both emissions and adaptation risks.

This report analyses the transition to reliable, round-the-clock renewable energy through solar, wind, and battery storage. Introducing the firm levelised cost of electricity (F-LCOE), it evaluates the cost-competitiveness of hybrid systems against fossil fuels and outlines the necessary policy reforms to support widespread deployment.

This briefing note outlines policy options to enhance Australia's fuel security through freight electrification. It recommends a phased, five-year, $3 billion programme to deploy up to 50,000 battery electric trucks, displacing one billion litres of diesel annually while leveraging private capital and implementing structural reforms.

This report examines the challenges facing the European automotive industry in transitioning to electric vehicles (EVs). It analyses shifting revenue streams, battery production costs, supply chain risks, and the need for charging infrastructure, while outlining financial tools to support adoption, research, and skills development.

Responsible investment has moved well beyond principles and pledges. Today’s challenges require practical capability and informed judgement. The RIAA Conference is a must-attend event for finance, sustainability and industry practitioners who want to focus on the key themes for responsible investment in 2026 and what implementation really looks like. Designed as an immersive, hands-on experience, the program focuses on the systems that underpin strong financial performance, and will help you understand how climate, nature, technology, governance and regulation intersect. 

These specially curated companion resources have been recommended by the conference speakers and Altiorem team.

Delhi heat vulnerability is shaped by neighbourhood density, limited green cover and unequal access to cooling. Using geospatial and household survey data, the report finds higher heat exposure increases illness, sleep disruption and productivity loss, while targeted greening, micro-level heat planning and energy-efficient cooling could improve urban climate resilience.

The report examines weaknesses in urban climate project preparation and argues that stronger coordination between cities, financiers and support organisations could improve coherence, efficiency and project impact. It identifies structural and operational barriers and proposes collaborative reforms to strengthen climate finance delivery.

Syria’s urban water and sanitation systems face rising climate-driven water scarcity, infrastructure damage and growing demand. The report recommends integrated water management, infrastructure rehabilitation, agricultural water efficiency, wastewater reuse and stronger governance to reduce future water insecurity, contamination risks and maladaptive investment.

C40 and Rebel outline how cities can structure urban adaptation projects to attract private finance, using ten case studies. Bankability depends on revenue logic, risk allocation, public de-risking, early financier engagement and credible monitoring.

The paper argues that pro-social preferences can offset ambiguity aversion in green finance by acting as a behavioural hedge. Using ambiguity-based investment models, the authors show socially motivated investors may accept uncertain green assets, lowering effective hurdle rates and supporting private capital flows into sustainable projects.

Policy brief outlining market-ready climate technologies for buildings, including heat pumps, insulation, renewable energy systems and circular construction practices. The report highlights financing, policy and capacity barriers, particularly in developing economies, and recommends stronger building codes, targeted funding, and integration of traditional knowledge to accelerate low-emissions, climate-resilient buildings.

The report argues current financial systems misallocate capital towards resource-intensive activities, hindering sustainability transitions. It recommends policy, governance and financial reforms to redirect investment towards resource efficiency, low-carbon development and equitable transition pathways, particularly in resource-dependent economies.

This series outlines the Forever Wild Initiative’s approach to financing and managing large-scale wilderness landscapes through blended capital models, community co-design, and nature-based enterprises. It documents the development of equitable nature finance structures that integrate conservation, economic activity, and social outcomes across landscapes.

Assesses 35 banks’ fossil fuel financing and climate policies in Southeast Asia, finding continued coal and gas funding despite commitments. International banks dominate financing, with policy gaps and loopholes persisting. The scorecard highlights misalignment with 1.5°C goals and calls for stricter divestment and increased renewable investment.
