Introduction

The urgent need to align infrastructure development with climate targets is now a central policy and investment challenge globally, particularly for low- and middle-income countries. Infrastructure drives a major share of carbon emissions—from energy production to heavy industry, transport, and water systems—making it both a major contributor to, and a critical lever for combating, climate change. Current infrastructure plans and investments must not only mitigate emissions but also build resilience to the accelerating impacts of climate extremes and environmental degradation. Effective financing mechanisms are vital for enabling this transition, channelling resources toward low-carbon, climate-resilient solutions, and ensuring that infrastructure investments address both immediate and long-term risks.

Modern investment in climate-compatible infrastructure calls for a new generation of financing strategies and support tools. These extend from direct project funding to the development of climate risk management frameworks, disaster insurance, and adaptation finance. Robust vulnerability assessments, blended finance mechanisms, and project pipelines specifically tailored to mitigation and adaptation have become essential. It is not enough to secure capital; projects must be designed and selected based on clear evidence of climate compatibility, integrating climate risk from the earliest planning stages through to investment decision and project delivery.

Looking ahead, unlocking climate finance and safeguarding future infrastructure against physical, regulatory, and transition risks demands the integration of national governance systems, private sector innovation, and international standards. Only by leveraging diverse sources—public, private, multilateral—and deploying financial instruments such as insurance, guarantees, and adaptation grants can countries bridge the climate financing gap, boost resilience, and support truly sustainable infrastructure growth.
