About TOSSD data
TOSSD data are available for activities from 2019 onwards on this website.
TOSSD data are organised in two pillars. Pillar I is dedicated to track 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, 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, on the other hand, 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 climate change mitigation, global health initiatives, and R&D in areas of global reach like renewable energy.
TOSSD adopts a recipient perspective and data 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)
TOSSD sector data are collected using either CRS or ISIC sector classifications. A mapping enables to display the data according to both classifications but please note that this is approximate as some sectors cannot be easily mapped.
Data presented only include data that comply with the TOSSD Reporting Instructions. As a consequence, these data may not reflect the entirety of a given provider’s co-operation portfolio. In particular, activities in non-TOSSD eligible countries carried out by some providers in the framework of South-South Co-operation do not appear in the export feature of the TOSSD.online visualisation tool, nor in the total financial amounts displayed in the tool.
To know more about TOSSD classifications and 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 a new 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 2023 TOSSD data
The data were updated on 2 March 2025.
As of 2 March 2025, a total of 126 providers reported TOSSD data for this data collection (See list here
Metadata containing additional, publicly relevant information on the data submitted to TOSSD is available here.
Under « aggregate » as a provider, the data include two sorts of activities, as indicated in their « project descriptions »:
- Non-concessional flows: semi-aggregates - while 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, some may be subject to confidentiality restrictions (in total, semi-aggregated transactions amount to USD 7 billion).
- Estimated data gaps: semi-aggregates – data gaps linked to providers reporting 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. for Germany, EBRD and the World Bank). Estimated data gaps amount to USD 75 billion in total.
Data on the amounts mobilised from the private sector are partially disclosed for confidentiality reasons. More restrictive confidentiality regimes apply to mobilisation data reported in TOSSD by multilateral development banks, following specific provisions included in data-sharing agreements between the OECD and these institutions. Data are disseminated in the form of semi-aggregates and include estimated data gaps.
Additionally, reflows on Private sector instruments (PSI) individual activities have been aggregated by Provider, Provider agency, type of finance and recipient.
The « source name » indicates the source of the data.
- TOSSD: activities reported to TOSSD only.
- CRS-TOSSD: activities reported to 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 that requested their CRS data to be shown in TOSSD for that year’s data, as a proxy.
- TOSSD estimate: non-ODA share of contributions to multilateral organisations in support of SDGs (Pillar II).
