The Council’s principal source of core income is dues from Members. The other major sources of income are grants from its host country France, various organizations and foundations.
The General Assembly approves draft budgets for the next triennium upon proposals received from the Governing Board, which is charged with finalizing the annual budgets. After consideration by the Committee on Finance and the Governing Board, the audited annual accounts are sent to all Members for approval. The ISC Regional Offices are mainly supported by their host countries, with some funding from ISC and other sources.
Annual dues are paid in accordance with Statute 37: ‘Each Member of the Council shall pay annual dues within a scale determined by the General Assembly”. The present dues are based on the decision of the 30th General Assembly of ISC’s predecessor organisation ICSU in 2011. Dues of Affilated Members are fixed at €500. A new dues structure, taking into account the new conditons following the creation of ISC, will be presented to the 2nd ISC General Assembly in 2021.
