What Partnership for Global Security does
Mission
The Partnership for Global Security (pgs) is a recognized international leader and innovator in nuclear and transnational security policy developing actionable responses to 21st century security challenges by engaging international, private sector, and multidisciplinary expert partners to assess policy needs, identify effective strategies, and drive demonstrable results.
As stated on its FY2025 Form 990.
Program
The Partnership for Global Security (pgs) is the original pioneer and thought leader on the nexus of climate change, nuclear power, global security, energy security, and nuclear geopolitics. Pgs has developed several dimensions of its activities. This began with the global nexus initiative (gni), which develops analysis and policy at the intersection of climate change, nuclear power, and global security. It has included a multinational multidisciplinary working group with representation from the nuclear industry, energy, environmental, diplomatic, legal, and global security communities. The nuclear readiness initiative (nri) is a proprietary, multidimensional, and analytical software tool designed to prepare the world for the next generation of nuclear energy, deployment, and security. Pgs also regularly publishes analysis, commentary, infographics, and aggregated news stories in its biweekly newsletter. Pgs staff are regularly consulted by the media and other expert organizations for its opinions and analysis on nucler nexus issues.

The organization over time
Each line starts at 100 in 2019, so what you read is the shape rather than the size: 150 means half as much again as 2019, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2020 to 2021, from $597k to $289k (−52%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2021 82%. Grants only. Government contracts and fees sit inside program revenue.
21% of PARTNERSHIP FOR GLOBAL SECURITY’s revenue is contributions — more earned-revenue than three-quarters of its peers (100% for the typical peer).
Surplus & reserves
