Sometimes called the “United Nations of chemistry,” IUPAC is formally a union of national chemistry or science associations that currently represent 57 countries, including Bangladesh, Croatia, Cuba, Kuwait, Nigeria, and Uruguay. IUPAC is governed primarily by a council composed of delegates from member nations. Individual chemists and companies may also join the union.
IUPAC’s work is done on a project basis, and anyone, whether formally affiliated with the union or not, may propose a project. Proposals are reviewed and approved by IUPAC’s divisions, which represent branches of chemistry, or standing committees, which represent areas such as chemistry education....
...Overall, approximately 1,400 volunteers actively contribute their time and expertise to IUPAC, supported by five full-time staff members, including Soby. IUPAC’s 2017 budget is about $1.5 million, which covers salaries and funding for projects, including travel for groups to meet in person, conferences, information technology, and other expenses.
IUPAC’s strength is its ability to gather outstanding scientists from all over the world to weigh in on projects of international importance. “These people are highly committed and give their very best,” says Mark Cesa, a retired industrial chemist who has been involved in IUPAC for two decades through its Committee on Chemistry & Industry and is the union’s immediate past-president.Just for comparison's sake, the American Chemical Society's 2015 operating budget was somewhere around 500 million dollars.
