Guided by the values and expertise of medicine and public health, Physicians for Social Responsibility (PSR) works to protect human life from the gravest threats to health and survival.

What we do

PSR mobilizes physicians and health professionals to advocate for climate solutions and a nuclear weapons-free world. PSR’s health advocates contribute a health voice to energy, environmental health and nuclear weapons policy at the local, federal and international level.

Reframing Nuclear Disarmament as a Health and Humanitarian Issue, PSR’s Nuclear Weapons Abolition Program has contributed to the international civil society movement that has tactfully reframed the prohibition and elimination of nuclear weapons as an urgent health and humanitarian issue.

PSR is the United States affiliate of International Physicians for the Prevention of Nuclear War (IPPNW) and a partner organization of International Campaign to Abolish Nuclear Weapons (ICAN), and PSR helped these civil society advocates to bring the Treaty on the Prohibition of Nuclear Weapons to fruition at the United Nations. On July 7, 2017, more than 120 nations voted to adopt the first-ever treaty that categorically prohibits nuclear weapons, following prior successful bans on chemical and biological weapons that achieved their sharp curtailment.  Circa April, 2022, 86 nations have signed and 60 have ratified the TPNW. 

PSR’s #DemandAccess involves young health professionals and concerned citizens in a campaign at the intersection of climate harm, nuclear threat, and issues of social and racial  justice in service of prioritizing the well-being of under-represented populations.  We seek to stop the diversion of needed public resources to the military-industrial complex, and redirect these to address human needs.

PSR actively participates in the Nuclear Grassroots Coalition and RECA Working Group (RECA = Radiation Exposure Compensation Act). PSR is also an original cofounder of Back from the Brink: The Call to Prevent Nuclear War a national grassroots initiative seeking to fundamentally change U.S. nuclear weapons policy and lead us away from the dangerous path we are on.
