Experience teaches that the Framework Convention on Global Health (FCGH) will need a financing facility if it is to garner widespread acceptance among low-income countries. The promise of financing is a well-established carrot to encourage countries to assume new convention-imposed obligations that will be costly to carry out. Promising to provide financing as part of an intergovernmental call for commitment also activates a rights-based approach. For donor and recipient countries, a funding facility embodies an actualization of their commitment to a convention’s collective undertaking to address a given issue. Donors signal their commitment through their contributions; recipients signal commitment through their efforts to use any support received to achieve the convention’s objectives. This essay highlights the need for an FCGH financing facility, provides a preliminary sketch of what it should look like, and urges the facility’s creators to adopt a bold and innovative approach that draws upon, but improves, current precedents.
