INESAP has succeeded in establishing a lively cooperation between scientists from more than 20 countries. This international cooperation is exemplified by its study on "Beyond the NPT - Towards a Nuclear-Weapons-Free World." This study was co-authored by a group of about 50 experts from 17 countries and published in New York during the 1995 Non-Proliferation Treaty (NPT) Review and Extension Conference. INESAP's innovative work has reached political decision makers. For example, it co-initiated the drafting of the model Nuclear Weapons Convention and contributed its scientific expertise to the drafting process. The model NWC became an official UN document in 1997 (A/C. 1/52/7) and is contained in the book "Security and Survival". A revised version of the mNWC, has been introduced to the United Nations General Assembly by Costa Rica and Malaysia (UN DOC A/62/650) in 2007 and is contained in the book "Securing our Survival". In their accompanying letter dated Dec. 17, 2007, the two countries explain that "This revised model takes into account relevant technical, legal and political developments since 1997. ... It is submitted as a work in progress setting forth legal, technical and political elements for the establishment and maintenance of a nuclear-weapon-free world."
INESAP publishes the INESAP Information Bulletin, monographs, technical reports, conference proceedings, and briefing papers. INESAP has organized international meetings in Geneva, Göteborg, Mühlheim, New York, Shanghai, Stockholm, Berlin, and other places.
INESAP conducted a number of international study groups. Currently INESAP supports the "Independent Group of Scientific Experts on the detection of clandestine nuclear-weapons-usable materials production" (iGSE). A completetd joint project of INESAP and the Nuclear Age Paece Foundation is "Moving Beyond Missile Defense".
INESAP conducts a series of simulated negotiations of the model Nuclear Weapons Convention in cooperation with the Interdisciplinary Research Group Science, Technology and Security (IANUS) at the Technical University of Darmstadt and the Centre for Science and Peace Research (ZNF) at the University of Hamburg.
