Nuclear Threat Initiative


The Nuclear Threat Initiative (NTI) is a nonprofit, nonpartisan global security organization focused on reducing nuclear and biological threats imperiling humanity. NTI collaborates with governments and organizations to raise awareness, advocate, and implement creative solutions. As an independent and trusted partner, we transcend traditional thinking and stimulate new ways to address urgent threats.


NTI’s nuclear, biological, and science and technology-focused programs bring our priorities to life through projects that build global engagement, generate actionable solutions, and catalyze change.  

  • NTI partnered with the Hiroshima Prefecture, Nagasaki Prefecture, and Hiroshima Organization for Global Peace to found #CranesForOurFuture, a movement of people and organizations who galvanize global support for a world without nuclear weapons by participating in an annual week of action around the anniversaries of the Hiroshima and Nagasaki atomic bombings.  

  • Through Horizon 2045, NTI, N Square, and the Center for Complexity at Rhode Island School of Design are charting a new path for global security free from the existential threat of nuclear weapons. Based on technical, social, and political cooperation, Horizon 2045’s “whole of society” initiative engages nontraditional actors—designers, ethicists, philosophers, cultural influencers, and more—to work in partnership with security experts to imagine and ultimately achieve a world without nuclear weapons by 2045, the 100th anniversary of the first atomic bomb.  

  • NTI continues to research and bring attention to cyber-nuclear threats, most recently with a new video, “Breaking Down the Cyber-Nuclear Threat.” In the video, former White House cyber czar Richard A. Clarke explains why the risk of cyber attacks on nuclear weapons should have us all concerned—and what we can do about it.  

  • Much of the existing literature on the climatic, economic, humanitarian, and societal effects of a nuclear exchange is out of date and inconclusive. NTI’s project on Understanding the Global Effects of Nuclear Conflict in the 21st Century is developing a research agenda for scientific and policy analysis of nuclear weapons effects to inform policy- and decision-makers with a clear and current picture of the existential consequences of nuclear use.


We are in a new and more dangerous era in which the likelihood of use of weapons of mass destruction is growing. NTI delivers innovative solutions that address these challenges and create lasting systemic change for a positive future.  

  • NTI’s Global Enterprise to Strengthen Non-Proliferation and Disarmament has convened a series of high-level, international dialogue to drive fresh, creative thinking, generate new ideas, and address political divisions that are stalling progress on nuclear disarmament.  

  • NTI created the International Partnership for Nuclear Disarmament Verification (IPNDV), a public-private partnership with the U.S. Department of State and more than 25 other countries. The IPNDV works to develop innovative monitoring and verification solutions that will be critical to achieving a world without nuclear weapons.  

  • NTI publishes two indices, the Nuclear Security Index and Global Health Security Index, which provide publicly available data about nuclear and health security conditions around the world. The Nuclear Security Index promotes actions to strengthen nuclear security and build confidence and it highlights countries’ progress and trends over time.  

  • NTI launched the International Biosecurity and Biosafety Initiative for Science (IBBIS), a new organization that works collaboratively with global partners to strengthen biosecurity norms and develop innovative tools to uphold them.


In all areas of our work, NTI is committed to amplifying the voices of those who have been, and continue to be, directly harmed by nuclear weapons. As NTI pursues new approaches to educate and engage influential allies and the public on reducing global nuclear and biological threats, we are eager to build partnerships and collaborative networks in and outside of the field.
