The IIR commits itself to improving quality of life and promotes sustainable development.
The bylaws of the IIR as an intergovernmental organization were defined by an International Agreement signed on December 1, 1954 and an Application Protocol signed on November 20, 1956.
Members of the IIR include Member Countries (there are now 61). Member Countries take part in IIR activities via the commission members they select. There are also other IIR members: corporate or benefactor Members (companies, laboratories, universities,...) or private (individual) members.
The IIR provides its members with tailored services meeting a wide range of member-country, national and international organization, decision makers', researchers' and refrigeration practitioners' needs.
