TOSSD aims to complement ODA by increasing transparency and monitoring important new trends that are shaping the international development finance landscape, including: i) the leveraging/catalytic effect of ODA, ii) the use of blended finance packages, and iii) the use of innovative risk mitigation instruments in development co-operation. TOSSD would incentivise broader external finance for development as a complement to developing countries’ own domestic resources.


The 2030 Agenda for Sustainable Development marks a shift from the Millennium Development Goals to a universal agenda with far-reaching aspirational goals, including the eradication of poverty and the end of hunger in the world, while preserving the planet. The OECD has carefully examined the international statistical system to understand how it could better promote the monitoring and review of resource flows aligned to support the 2030 Agenda. A new measure has been proposed and is provisionally entitled: total official support for sustainable development (TOSSD) (see Addis Ababa Action Agenda (AAAA) (para 55) and OECD DAC HLM 2014).

Going forward, the OECD will do its part to support international collaboration with traditional donors, south-south and emerging providers, multilateral institutions, civil society organizations, foundations, and the private sector to shape and operationalise the TOSSD measurement framework.
