This guide outlines how local governments can access green finance by shifting from ad hoc initiatives to embedded institutional strategies. Highlighting successful international examples, it emphasises the importance of transparent governance, predictable project pipelines, and standardised reporting to build investor confidence and secure long-term climate capital.

This report examines the impacts of Hurricane Ida in south Louisiana, using a multi-hazard framework to attribute economic damages to historical and projected climate change. It finds that total damages were 19% higher in 2021 due to historical climate change and could be 76% higher by 2071.

Climate Central’s database tracks the most costly U.S. weather and climate disasters since 1980, providing data on events causing $1 billion in damage.

This report presents a comprehensive framework and toolkit to help governments and stakeholders manage extreme heat risk. It provides actionable guidance, a maturity assessment tool, and strategies to operationalise governance and develop effective heat action plans across multiple sectors and timescales.

This research provides household-level estimates of flood risk exposure across socioeconomic groups in the US. It reveals that high-income households own a disproportionate share of floodplain property wealth, whilst a vulnerable subset of low-income, uninsured homeowners faces severe financial risks from flood damage and rising insurance premiums.

This report explores how the insurance industry assesses physical climate risks for new social infrastructure projects. It identifies five key enablers to integrate climate resilience across project lifecycles, advocating for early stakeholder engagement and forward-looking risk assessments to ensure long-term asset insurability, bankability, and value in a changing climate.

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 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.

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.

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.

This article argues that modern investment strategies fuel economic extraction while often underperforming simpler alternatives. It calls on investors to realign portfolios with productive, community-oriented investments that generate real economic and social value.

The article interprets Copernicus’s Global Climate Highlights 2025 as a shift from episodic extremes to a structurally warmer, more volatile baseline. It argues that persistent temperature exceedances, ocean heat, cryosphere decline, and overlapping hazards demand a move from climate risk awareness to disciplined adaptation and continuity planning.

This article argues the global food system is the largest source of human-caused methane and deserves far more policy and funding attention. It maps key emission “hot spots”—ruminant livestock, food waste in landfills, biomass burning, and flooded rice fields—and outlines practical mitigation options from dietary shifts to landfill capture and improved rice management.
