This report assesses mine-closure strategies for artisanal and small-scale gold mining in Marmato, Colombia. Applying a systems-based valuation methodology, it highlights the economic and environmental benefits of progressive formalisation and closure, emphasising early risk reduction, physical stabilisation, and ecosystem rehabilitation to improve territorial safety.

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 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.

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.

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.

This month’s sustainability roundup traces a rapidly evolving landscape in climate governance and industrial transition, highlighting the convergence of ISSB-aligned disclosure standards and emerging carbon trade measures alongside shifting cost curves in transport and critical minerals. It underscores how tighter emissions accounting and border policies are embedding carbon competitiveness into capital allocation, while advances in electrification, AI-driven power demand and expanding legal accountability are integrating climate and nature risk into mainstream financial decision-making.

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.

Future Energy Scenarios 2025 provides independent pathways for Great Britain’s energy system to reach net zero by 2050. It models demand, supply, flexibility and emissions across electricity, gas and hydrogen, assessing costs, infrastructure needs, carbon budgets and policy choices under varying levels of electrification, hydrogen deployment and consumer engagement.

The IEA’s Energy and AI report examines AI’s rising electricity demand and its capacity to improve energy efficiency, security and innovation. It assesses data centres, grids and end-uses, highlighting skills, infrastructure and policy needs to manage costs, emissions and resilience globally.

This report assesses Australia’s escalating climate risks and argues for scaling adaptation investment. It recommends improved valuation methods, a nationally coordinated adaptation investment framework, and diversified public-private financing mechanisms to reduce long-term economic damage and enhance resilience.

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.
