Each September, New York Climate Week brings together policymakers, investors, corporate leaders, regulators and civil society leaders to advance climate action across capital markets and policy. The 2026 edition, held from 21-25 September, included more than 1,000 events across the city with over 100,000 attendees. This week offered a valuable snapshot of how climate-related risks and opportunities are evolving across portfolios. Below are the key cross-cutting takeaways gathered by our Responsible Investment team. 

Net-zero remains central; however, implementation and accountability is becoming the priority  

Investors continue to view climate change as a material financial risk and consider climate-related stewardship as part of their fiduciary duty. Discussions highlighted the importance of practical implementation of portfolio strategies, supported by climate target setting frameworks. Investors are analyzing the practical realities of decarbonization implementation, while facing increasing challenges around adaptation, physical risks and long-term resilience. Across sectors and asset classes, the overall direction points towards moving beyond high-level commitments to measurable outcomes that can protect portfolios and support sustainable economic growth.  

As a signatory and current co-chair of the Net-Zero Asset Owner Alliance (NZAOA), UNJSPF is helping to advance industry discussions on implementation and accountability of net-zero commitments. This reflects the importance UNJSPF places on integrating climate-risk considerations as a core component of our long-term portfolio management objectives.  

Transition finance is shifting from commitments to credibility 

Between 2024-2025, annual energy transition investment was estimated at roughly US$2 trillion, with clean-energy technology costs declining by about 90 per cent since 2010. Today, risk-management focus is shifting from commitments to implementation, with capital increasingly allocated to climate solutions and adaptation, and engagement strategy being sharpened for real-economy emissions reduction. Across asset classes, investors are evaluating whether transition plans are durable under a range of policy and market scenarios.  

This approach aligns with UNJSPF’s active ownership and engagement strategy to mitigate our portfolio’s risk. 

Energy security is becoming a key investment theme 

One of the recurring themes across Climate Week was that energy security is progressively linked to national security and affordability. With growing electricity demands driven by artificial intelligence, data centers and the energy transition, ecosystem services are being depleted, and infrastructure’s 25–30-year horizon means investors must design and operate the next generation with long-term climate risk in mind. Discussions highlighted the vulnerabilities in supply chains, limitations in transmission capacity and growing geopolitical competition around critical minerals. In parallel, infrastructure investment opportunities continue to expand as governments and companies seek to revamp energy systems to improve resilience.  

For long term investors such as the UNJSPF, the challenge is to mitigate stranded asset risk and to ensure that new infrastructure is designed to withstand evolving climate conditions over the decades to come.  

Physical climate risk is moving to the forefront  

This was one of the most widely discussed topics throughout the week. Investors expressed growing concern regarding the economic impacts of extreme weather events, reinforcing the case for far greater investments in resilience. Discussions highlighted that resilience should not be viewed only through an environmental lens. Supply chain stability, business continuity efforts and long-term financial performance are linked to a company’s ability to anticipate and adapt to physical climate risks.  

Despite adaptation planning reportedly rising from 19 per cent in 2022 to 44 per cent today, better measurement of company-level adaptation quality remains a key missing piece. 

For the Fund, strengthening physical-risk analysis across asset classes will remain an important project to strengthen prudent long-term investing. 

Policy uncertainty reinforces the importance of having a long-term perspective 

A key question that came up during discussions is whether climate resilience is becoming durably investable, even though portfolio risk cannot be fully hedged from the broader economy, underscoring investors’ need for long-term stability and resilience. Investors expressed concern about regulatory uncertainty and shifting policy frameworks. However, many noted that adaptation, resilience and energy transition investment are increasingly being driven by economic and financial realities. The conversations reinforced the value of maintaining a long-term perspective, focusing on structural trends and collaboration with partners. 

Reporting standards to continue to convergence 

Despite the availability of more sustainability data than ever before, a mosaic of data points makes it hard to form a clear risk picture, and a company’s own view of its long-term earnings risk remains most useful. Participants highlighted the growing adoption of the International Sustainability Standard Board (ISSB) requirements, 18 jurisdictions are now live on ISSB, however, broader efforts are needed to harmonize sustainability disclosure frameworks. The focus is shifting toward identifying the most financially material risks and opportunities rather than collecting additional metrics for compliance purposes.  

AI is creating new opportunities and new challenges  

Artificial intelligence emerged as a major cross-cutting theme during Climate Week. Participants discussed the rapid expansion of data centers, rising electricity demand and growing pressure on existing infrastructure systems. While it is understood that digitalization will not slow down, and demands continue to rise even as efficiency improves, technology companies must deliver local jobs and partnerships to sustain community support, while growth in self-generation capacity reflects a push for energy self-reliance and predictable pricing. 

These developments highlight the need for investors to assess AI-related risks and opportunities across the entire value chain.  

Looking ahead 

Our biggest takeaway from Climate Week is that responsible investment is entering a more mature phase. Decarbonization remains essential, and investors are increasingly focused on resilience, adaptation, energy security and the practical implementation of transition strategies. 

For us at UNJSPF, these developments underscore the importance of integrating climate transition analysis, physical-risk assessment, and active stewardship into investment decision-making. As climate-related challenges become even more interconnected with economic and geopolitical trends, a long-term approach remains critical to protecting and enhancing the Fund's assets on behalf of our beneficiaries.
