Key Takeaways

The discussion explored the role of infrastructure investment in building a more sustainable and resilient economy. Infrastructure is essential to economic activity, energy security and social well-being. Its long lifespan also means that today’s decisions will have an impact in the long term.

Sustainability and energy security are increasingly important considerations for infrastructure investors in order to create resilience. However, these investments involve significant risks due to geopolitical instability, security uncertainty and systemic change. This makes attracting long-term capital particularly difficult in developing economies, where political tensions can significantly affect investment conditions.

The discussion highlighted a fundamental challenge: although infrastructure can generate long-term economic and social benefits, these benefits are not reflected in the financial returns available to investors. This can discourage investment in projects that are valuable to society but difficult to finance commercially.

A speaker highlighted the importance of clearly defining sustainability, questioning whether an infrastructure investment is considered sustainable because of the project itself or because it operates within a sustainable sector.

Another speaker emphasized the importance of trust in climate data and transition strategies. Although these strategies are based on scientific data, challenges remain in how that data is communicated and trusted. In addition, infrastructure assets were not designed to withstand the physical impacts of climate change, making adaptation and resilience increasingly important.

Gaps & Opportunities

A significant gap is the lack of a shared understanding of what constitutes a sustainable infrastructure investment. A project may improve energy security or economic development while still creating significant environmental costs. Investors need consistent criteria to evaluate these trade-offs and assess the value of such investments.

A second challenge is risk allocation. Despite infrastructure investment having particularly visible returns, having far away capital remains a risk. In addition, political and geopolitical uncertainty contributes to this risk. Meanwhile, investors have different priorities, time horizons and expectations, making it difficult to agree on common investment strategies.

Another gap exists between the long-term nature of infrastructure assets and the increasing physical risks associated with climate change. Existing infrastructure may not be sufficiently resilient to extreme weather or changing environmental conditions. Investment decisions must therefore consider both mitigation and adaptation.

Nevertheless, these challenges create opportunities for partnerships between asset owners. By working together, asset owners could pool capital, strengthen their influence with investors, or achieve both. Such partnerships could help align private returns and public benefits.

Recommendations

• Investors and policymakers should develop clearer and more consistent definitions of sustainable infrastructure. Assessments should consider the full lifecycle of an asset, including emissions, resource consumption, social impacts and resilience to future climate conditions.
• Asset owner partnerships should be developed to mobilise long-term capital. By collaborating on large infrastructure projects, investors can share expertise, diversify certain risks and improve their ability to finance projects with significant social and environmental benefits. Public institutions can help where appropriate by improving regulatory certainty and addressing risks that private investors cannot reasonably bear alone.
• Climate resilience should become a central part of infrastructure investment decisions. Investors should evaluate whether assets can withstand future climate conditions, rather than relying only on historical data. Transparent methodologies and reliable scientific evidence are essential to building confidence in these assessments.
• Policymakers and investors should improve the conditions for private investment in sustainable infrastructure, particularly in developing economies. Clear regulations, appropriate risk-sharing mechanisms and credible project preparation can help attract long-term capital without transferring unreasonable costs to the public.
