New York City — September 21-28, 2025 — During NY Climate Week 2025, the Anthropocene Institute contributed to highlighting nuclear energy into the global climate conversation — sponsoring the Nuclear Symposium 2025 and engaging with investors, policymakers, and innovators throughout the week’s broader events.

From shaping policy dialogue on carbon markets to building relationships with emerging climate-tech funds, Anthropocene’s team highlighted one central message: nuclear must be recognized and enabled as a scalable, equitable tool for decarbonization.

Spotlight: Nuclear Symposium 2025

Anthropocene was a “Megawatt” sponsor of the Nuclear Symposium 2025, hosted by Nuclear New York. The Symposium brought together global industry leaders, financiers, and policy experts for a full day of panels exploring the future of advanced reactors, market incentives, and climate-driven investment.

Anthropocene’s Guido Núñez-Mujica, Director of Data Science, joined the finance-focused session “Innovating Finance: De-risking Through New Models and Capital Stacks.” He spoke alongside Charlie Penner (Ananym Capital Management), Matthew Barry (Nano Nuclear), Simon Irish (Terrestrial Energy), and Brianna Lazerwitz (Nuclear New York).

Guido’s remarks focused on the urgent need to bring affordable, reliable nuclear power to the regions driving global economic and population growth — Africa, Southeast Asia, and South America.

The Symposium also showcased Anthropocene’s Nuclear Costs Dashboard, staffed by Anthropocene’s research team and well-trafficked by attendees looking for clear, comparative data on reactor economics. On that same evening, Alumni Ventures (AV) hosted "Nuclear Night," a major nuclear energy gathering that drew founders, investors, policymakers, and climate leaders to discuss the future of nuclear fission and fusion. 

Engaging the Climate & Investment Ecosystem

Beyond the Symposium, Anthropocene’s presence extended across Climate Week’s dense network of salons, panels, and side events:

• Atlantic Council Nuclear Energy Policy Summit 2025: Anthropocene joined this strategy meeting hosted by the Atlantic Council, where global nuclear leaders, policymakers, and financiers debated the next wave of policy priorities for advanced reactors. The Summit offered high-level, candid exchanges on regulatory modernization, capital formation, and how to integrate nuclear into national decarbonization strategies.

• Carbon market realism: In an AI, Energy & Carbon Credits panel, Anthropocene engaged carbon market players about the barriers to recognizing nuclear in voluntary and compliance markets. While some expressed skepticism about near-term adoption, the conversation reinforced the need for persistent, informed policy work.
  
  
• Defense & security perspective: At the New Climate national security salon and dinner, Anthropocene connected with leaders from defense, DoD, and maritime technology circles — conversations underscoring the strategic importance of domestic shipbuilding, critical minerals supply chains, and load-following advanced nuclear.
  
  
• Industry news & connections: Informal updates surfaced throughout the week showcasing innovative ways of moving the nuclear industry forward:
  
  
  • Terrestrial Energy CEO Simon Irish is preparing to go public via SPAC.
  • Developers are seeking capital to revive partially built reactor sites.
  • There’s continued movement within DoD on microreactor RFPs despite administrative change.

• Nuclear Night NYC: After the symposium, the Anthropocene team brought the Dashboard over to the Alumni Ventures Nuclear Night NYC party, where guests interacted with the dashboard in an energetic and fun atmosphere. Matt Loszack, CEO of Aalo Atomics, and Adriel Barret-Johnson, Director of Strategy at X-Energy spoke about exciting new developments for their companies and advanced nuclear.

Why It Matters

Anthropocene Institute’s Climate Week engagement underscored a key reality: global clean energy demand is growing faster than current policies and finance models can keep up. By bringing advanced nuclear into mainstream climate and investment conversations — and by advocating for fair treatment in carbon markets — Anthropocene is working to accelerate a just, practical, and scalable energy transition.

The week reinforced several takeaways for the Institute’s mission:

• Policy reform is urgent and achievable — especially around carbon credit eligibility.
• Capital stacks and risk-sharing models are evolving quickly; early participation shapes the field.
• Education for policymakers and investors remains critical to move from hype to deployment.
• Global equity matters: the clean energy future must reach the regions growing fastest.
