Our Impact It is the physician's responsibility as a scientist to share their knowledge with the public. But as clinician, they are an active participant, not only an impartial supplier of information. The aim of PSR is to provide the scientific data on which political decisions must in part be based.

Collaboration Yields Valuable Health Resources

PSR’s partnerships with allied organizations in the climate movement have yielded valuable health resources for advocates.

5 key findings

Highlighting the trends in the emerging scientific evidence on fracking:

  • Serious harm to public health, and no regulatory framework can prevent those harms.
  • Drinking water contamination from drilling, fracking, and disposal of fracking waste.
  • Fracked gas is a grave threat to the climate, and may be worse than coal due to substantial methane leaks.
  • Fracking infrastructure poses serious exposure risks to those living nearby.
  • Fracking raises environmental justice issues.

A 15% nationwide reduction in annual electric consumption means:

$20 Billion

Up to this amount in avoided health harms.


More than six lives saved each day.


Nearly this amount of fewer asthma attacks.

PSR mobilizes physicians and health professionals to contribute public health solutions for climate change and nuclear weapons abolition.

Nuclear Weapons Abolition

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.

ICAN/Clare Conboy
In December 2017, the Norwegian Nobel Committee awarded ICAN the 2017 Nobel Peace Prize in recognition of their work raising awareness on the catastrophic humanitarian consequences of any use of nuclear weapons and achieving the milestone treaty.

Physicians and health professionals’ medical expertise contributed to the successful adoption of the treaty:


PSR and IPPNW co-released the report Nuclear Famine: 2 Billion at Risk?, which offers scientific data on the global health and climatic impacts of a regional nuclear war. This foundational study grounded ICAN’s claims about the immense and horrific humanitarian impacts of nuclear weapons in scientific evidence.


PSR board member and co-president of IPPNW Ira Helfand, MD contributed testimony on the medical consequences of nuclear weapons to the Open-Ended Working Group (OEWG) established by the U.N. General Assembly. The OEWG voted to recommend to the U.N. First Committee that the U.N. sanction negotiations for a treaty.


PSR’s team of physicians attended the U.N. negotiations on the Treaty on the Prohibition of Nuclear Weapons to lobby national delegations to cast their vote in support of the treaty. PSR delivered 22 “yes” votes, contributing to a successful vote of 122 nations in support of the adoption of the treaty, one against and one abstention.
