About TOSSD data
TOSSD data are available for activities from 2019 onwards on this website.
TOSSD data are organised in two pillars. Pillar I shows cross-border flows to developing countries, while Pillar II tracks regional and global expenditures with substantial benefits to developing countries. In addition, amounts mobilised from the private sector are shown separately.
From 2023 data onwards, TOSSD introduced two sub-pillars under pillar II, to better categorise and report the diverse range of activities.
- Sub-pillar II.A includes activities that provide direct benefits to developing countries and/or their populations. Examples include Research and Development (R&D) in areas specific to developing countries (e.g. malaria research), support to refugees/protected persons, and earmarked contributions to multilateral organisations targeted at addressing issues specific to developing countries or their populations.
- Sub-pillar II.B encompasses activities that contribute to international public goods and address challenges/issues of global nature. These activities are crucial for sustainable development on a broader scale and include efforts such as global health initiatives, or R&D in areas of global reach like renewable energy, agriculture or clean air.
TOSSD data are presented from the recipient perspective and totals are based on gross disbursements. Further details, e.g. on the providers and amounts committed, are available in the data downloads (see Browse Activities / Export Results). Some South-South co-operation (SSC) is not quantified in monetary terms, following the UN agreed methodology to measure SSC. However, those activities are also included in the recipient perspective.
TOSSD sector data are collected using either TOSSD-CRS or ISIC sector classifications. A mapping enables to display the data according to both classifications.
Currently, the list of TOSSD recipients includes 10 countries and territories that are no longer ODA recipients. TOSSD data presents both the official support and mobilised private finance reported for these countries.
To know more about the TOSSD methodology, please consult the TOSSD Reporting Instructions and the TOSSD code list available on TOSSD.org.
What is TOSSD ?
The Total Official Support for Sustainable Development – TOSSD – is an international statistical framework for monitoring official resources and private finance mobilised by official interventions in support of sustainable development of developing countries.
Notes on the 2024 TOSSD data
The data were last updated on 24 February 2026.
As of 12 March 2026, a total of 128 providers reported TOSSD data on activities in the year 2024 (See list here
Under « aggregate » as a provider, the data include two sorts of activities, as indicated in their « project descriptions »:
- Non-concessional flows: semi-aggregates - the bulk of data on bilateral non-concessional flows and export credits are shown at activity level for providers that have agreed to their disclosure. However, some activities are subject to disclosure restrictions (in total, for 2024, semi-aggregated transactions amount to USD 22 billion).
- Estimated data gaps: semi-aggregates – data reported to the OECD DAC (Creditor Reporting System) but not to TOSSD have been estimated to facilitate the use and interpretation of TOSSD data (i.e. Germany and the World Bank Group). For 2024, estimated data gaps amount to USD 77 billion in total.
Data on the amounts mobilised from the private sector are disclosed partially for data sensitivity reasons. Restrictive data disclosure regimes apply to mobilisation data reported in TOSSD by multilateral development banks and some other multilateral organisations, following specific provisions in data-sharing agreements with some of these institutions. Data are disseminated in the form of semi-aggregates and include estimated data gaps.
Additionally, reflows on loans to the private sector, equity and mezzanine finance instruments by bilateral providers are aggregated by provider, provider agency, recipient and financial instrument.
The column "source name" in the exported data files indicates the source of the data:
- TOSSD: activities only reported to TOSSD.
- CRS-TOSSD: activities included in both CRS and TOSSD.
- CRS data used as proxy: activities for reporters that were not able to carry out a special TOSSD reporting exercise in a given year but requested their CRS data to be shown in TOSSD as a proxy.
- TOSSD estimate: non-ODA shares of contributions to multilateral organisations in support of SDGs.
