Total Official Support for Sustainable Development (TOSSD)
Definition
Total Official Support for Sustainable Development is an international statistical framework, developed through an OECD-convened task force, measuring the full range of officially supported resources flowing to sustainable development: concessional and non-concessional official finance, private finance mobilised by official interventions, and support to global public goods. It complements Official Development Assistance (ODA) by capturing South-South cooperation, triangular cooperation and mobilised private finance that ODA excludes, aligned with SDG target 17.3.

Why it matters
You cannot manage a financing system you only partially measure; TOSSD is the attempt to count the whole of it.
