This month’s sustainability roundup captures a shift from framework development to real-world application, where climate and nature risks are increasingly embedded across financial systems, legal accountability, and decision-making. It highlights how intensifying physical climate signals, evolving disclosures, and maturing litigation are converging with insights on sovereign risk, energy systems, and corporate strategy. Together, these developments show how sustainability is moving beyond principle—being tested, priced, and enforced across markets, regulation, and the real economy.

Examines public perceptions of drought risk and provides evidence-based guidance for communicating climate-related drought in the UK. Emphasises audience values, narratives, trusted messengers, and linking local impacts to broader climate change to improve engagement and support for adaptation measures.

Analyses climate-linked migration, highlighting impacts on displacement patterns and vulnerabilities. Evaluates roles, motivations and barriers for refugee- and migrant-led organisations, and proposes funding and policy interventions to strengthen their engagement in climate advocacy and support adaptive, rights-based responses.

The report argues the hydrological cycle should be governed as a global common good, with water valued more accurately and managed for efficiency, equity and environmental sustainability, supported by five missions spanning food systems, ecosystems, circular water use, lower water-intensity industry, and universal safe water access. The report is produced by the Global Commission on the Economics of Water, supported by the OECD.

Colorado School of Mines is a public research university in Golden, Colorado specialising in engineering, applied science and technology. Founded in 1874, it delivers undergraduate and graduate programmes focused on energy, earth sciences and sustainability, and conducts industry-connected research addressing global challenges in resources, environment and advanced engineering fields worldwide.

All Will Rise is a narrative courtroom deck-building video game funded via Kickstarter. Players lead a team investigating environmental harm and build arguments through card-based mechanics to prosecute a powerful corporation for destroying a river, combining investigation, strategy and storytelling in a political crime-thriller setting.

This BIS working paper analyses water scarcity’s macroeconomic effects using panel data for 169 countries (1990–2020). It finds higher water stress is associated with lower GDP and investment growth and higher inflation. The paper discusses sectoral impacts, pricing, infrastructure and climate scenarios, highlighting implications for economic policy and central banks.

National Oceanic and Atmospheric Administration (NOAA) is a US government science agency focused on understanding and predicting changes in climate, weather, oceans and coasts. It provides environmental data, severe weather forecasting, climate monitoring and marine ecosystem management to support public safety, commerce and research.

Aqueduct Floods is an interactive tool by WRI that maps current and projected riverine and coastal flood risk globally. It enables users to assess exposure, urban damage, and economic impacts under different climate scenarios, supporting risk analysis, resilience planning, and investment decision-making at country and sub-national levels.

Guidance from UNEP FI and the Equator Principles on integrating project-related finance into nature-based risk assessments. It outlines frameworks, governance and disclosure expectations to help financial institutions identify, assess and manage biodiversity, water and pollution-related risks at project and portfolio levels.

This McKinsey Global Institute report assesses current and projected costs of adapting to heat, drought, flooding and wildfires under a 2°C warming scenario. It estimates $190 billion is spent annually today, rising to $1.2 trillion by 2050 for developed-economy protection standards, with benefits outweighing costs.

This study develops a climate risk index for 1,455 US municipal drinking water utilities and compares projected risks with municipal bond disclosures. It finds material mismatches between climate risk and disclosure, highlighting utilities where climate adaptation and financial risk management may be insufficient.

The Climate and Catastrophe Insight is an annual research series that provides a consistent global view of natural disaster activity and climate-related catastrophe trends. It examines impacts on people, assets and economies to support risk assessment, resilience planning and long-term decision-making.

This month’s sustainable finance article roundup examines a landscape increasingly shaped by geopolitics and climate risk, as near-term fragmentation, energy security, and affordability pressures collide with intensifying long-term threats from climate change, biodiversity loss, and water stress. The works featured analyse how these dynamics are reshaping capital allocation, disclosure, and resilience planning, demonstrating the growing need for sustainable finance to integrate geopolitical risk with real-economy transition.

The Planetary Health Check is an annual benchmark series providing a consistent, science-based assessment of the Earth system. It applies the Planetary Boundaries framework to monitor planetary stability, resilience, and life-support functions, supporting comparability over time and informing policy, finance, and strategic decision-making and Planetary Boundaries Science is a research lab within the Potsdam Institute for Climate Impact Research (PIK), focused on advancing scientific understanding of the planetary boundaries framework. It does not operate as an independent organisation and should be covered under PIK’s institutional profile.

The State of Global Water Resources is an annual benchmark series produced by the World Meteorological Organization. It provides a consistent, global overview of freshwater conditions across key components of the hydrological cycle, supporting comparative assessment and decision-making across regions and time.
