Total Official Support for Sustainable Development (TOSSD): Game changer or mirage?

Total Official Support for Sustainable Development, or TOSSD is a new statistical metric that has been in the making for almost 10 years. It is meant to capture a broad range of global flows of public money in support of sustainable development. These include aid, loans on non-concessional terms, and public funds aimed at mobilising private finance for development.

Metrics matter. It is essential to track the resources that the international community is allocating to turn the ambitions of Agenda 2030 and its Sustainable Development Goals (SDGs) into reality. Without such data, it is impossible to determine whether there is progress.

ActionAid, AidWatch Canada and Oxfam International are publishing this discussion paper to shed light on how TOSSD works in practice as well as on its ambitions, shortcomings and the contending political perspectives on this new metric. The paper emphasizes that TOSSD could significantly shape the future of development finance.
