This paper outlines six practical options that non-nuclear weapon states could pursue to reduce nuclear risks amid heightened geopolitical tensions. The options were developed based on interviews with nuclear policy experts from around the world. They reflect priority areas where government investment could have the most near- to medium-term impact, as well as the tools and channels through which these efforts could be advanced.
