Managing the risks of climate change will require developing safe, secure, and economic low-carbon energy sources that enable growth while protecting people and the environment. The Global Nexus Initiative (GNI) is a multi-year joint effort by PGS and the Nuclear Energy Institute to explore the linkages among climate change, nuclear power, and global security issues. PGS and NEI have assembled a GNI Working Group that includes 16 highly accomplished, multidisciplinary international professionals with policy expertise in energy, nuclear, climate change, and security issues. Members represent the United States, Europe, and Asia.

The project represents a new level of real-world collaboration among non-traditional partners who agree that the complex challenges posed by climate change, energy demand, and global security require a new level of real-world collaboration and innovative policy solutions. The GNI Working Group will convene for a series of results-focused workshops to develop actionable and innovative policy recommendations for international leaders and policymakers.

During the initial project phase, the GNI produced three major policy memos that described the primary challenges and offered recommendations for addressing them. These memos fed into the groundbreaking report, “Nuclear Power for the Next Generation: Addressing Energy, Climate, and Security Challenges,” published in May 2017. The report included four key findings and offered 22 actionable policy recommendations.

In the second phase of its work, from 2017-2019, the GNI will engage in a series of workshops and small meetings to develop policy recommendations that address the evolving challenges created by the development and deployment of advanced nuclear reactors, emerging nuclear suppliers and newcomer nuclear states, and the geopolitical implications of nuclear power in the 21st Century.

Our objective is to create a transparent and productive process that generates realistic and actionable recommendations for policymakers. The findings of the GNI will reflect workshop outcomes and the viewpoints of the Working Group members, not artificial consensus or ideological preconceptions.

GNI is currently funded by a generous grant from the John D. and Catherine T. MacArthur Foundation.
