Concessional loans for Africa's climate crisis: Whose fiscal effort?
What volume and proportion of finance to African countries for climate action came as loans in 2022? Is it targeting need? We look at data from the DAC, IDA and China.
DownloadsOverview
This factsheet analyses debt resulting from public concessional loans for climate action received by African countries. It explores loans for adaptation, mitigation or both.
It highlights that a significant volume and proportion of public concessional finance directed at addressing climate challenges in Africa is being provided in the form of loans. Although these will be repaid at lower-than-market rates and/or have longer maturity and grace periods, they will ultimately need to be repaid.
Finance supporting sub-Saharan African countries’ response to climate change, particularly the least developed African countries[1] and those at risk of climate disaster, should be primarily grant-based, covering as many eligible countries as possible. Non-grant-based financing risks exacerbating national debt burdens that are already significant for many African countries. It also raises the question of who is ultimately paying for climate action in countries that contributed the least to the climate crisis.
Introduction
Close to two-thirds (64%) of African countries are classified as among the world’s most vulnerable to the negative impacts of climate change.[2] The continent also hosts close to 60% of low-income countries that are either already in external debt distress or at high risk of external debt distress.[3] Africa’s debt burden has been growing since the 2008 global financial crisis.
Since the early 2010s, the risk of a fiscal crisis in Africa, particularly in sub-Saharan Africa, has more than doubled. Additionally, the interest payments to revenue ratio in this region is approximately four times higher than that of advanced economies.[4] Africa’s public and publicly guaranteed (PPG) external debt tripled to US$657 billion between 2008 and 2022, representing 60% of its external debt. By 2022, its median total external debt had doubled to nearly 50% of GDP (with PPG external debt accounting for most of this debt).[5] This is especially alarming because African debt held by private creditors has been growing due to the high cost of borrowing, and African debt is especially sensitive to growth and fiscal shocks.[6]
Vulnerability to climate crises and limited fiscal space create the perfect storm for Africa. Of the 10 countries most at risk from climate disaster, seven are in the region.[7] Many African countries have low adaptive capacity, which makes them vulnerable to food insecurity and declining income.[8] With limited fiscal space and the high costs associated with addressing climate change, many African countries rely on external financing and require assistance from global partners.[9] Although concessional financing, particularly in the form of grants, is the most suitable option, many African nations end up borrowing to fund climate action.
A loan, whether on favourable terms (concessional) or not (market rate) is ultimately a debt-generating mechanism. African countries are finding themselves in climate ODA loan debt despite not carrying any historical responsibility for the climate crisis.
Some developing countries recognise loans for climate action as part of their own nationally determined contribution[10] while the African Group of Negotiators (AGN)[11] argues that financing that requires return payments should not be counted as climate finance: [12]
“Loans as financial instruments together with green bonds, are not to be considered as climate finance, as both are to be paid back with interest rate that is higher than interest rate applied in developed countries, thus they are pure revenue generating instruments’’
Gabon, on behalf of the AGN,
Furthermore, the use of non-concessional (market-based) loans as climate finance is contrary to the spirit of the United Nations Framework Convention on Climate Change (UNFCCC), where the responsibility of transferring resources rests with developed countries. For this reason, we have not assessed non-concessional financing to climate action.
In this factsheet, we explore key data points that show how ODA is being used in concessional loans for climate action – which countries receive the most, and whether loans are matching Africa’s priorities? We also look at trends in how the World Bank’s International Development Association (IDA) and China – among the biggest providers – are deploying loans. We conclude with a section of key recommendations for how financing in response to the climate crisis should be provided to equitably meet recipients’ needs, and argue that loans should be considered as fiscal effort on the part of the recipient towards its nationally determined contribution, rather than fiscal effort on the part of the donor. This should inform how the New Collective Quantified Goal (NQCG)[13] on climate finance is measured.

About the data in this paper
We use the most recently available dataset (data for calendar year 2022, published in late December 2023). This factsheet includes data on concessional loans (low or no interest rate) in the form of official development assistance (ODA) reported to the Organisation for Economic Co-operation and Development’s Development Assistance Committee (OECD DAC) and concessional loans from China to African countries (all African Union members) – these are identified using the same criteria as the OECD’s ODA definition. Data for the latter was sourced from AidData's Global Chinese Development Finance Dataset, Version 3.0.
Climate adaptation and mitigation statuses are based on donor-provided Rio markers,[14] where available. For donors that have not screened their ODA for climate adaptation and mitigation, a combination of keyword search and a novel machine-learning algorithm was used to generate classifications. You can read more about this methodology in the annex.
Key facts
The latest data, from 2022, shows that:
- Two-thirds of climate-action ODA to Africa comes in the form of loans
- Over half of climate-action ODA to Africa targets adaptation
- 45.2% of all adaptation grants were concentrated in just five countries
- African LDCs get most adaptation ODA as loans
- IDA, the main financer of climate action in Africa, gave 83% of adaptation ODA as loans
- IDA used loans more often for climate-related projects than for non-climate related projects in Africa
- 83.5% of IDA’s loans for adaptation in Africa are concentrated in five countries
- China is Africa’s third-largest provider of concessional climate loans, based on our estimates
- Chinese concessional loans for climate are more expensive than non-climate loans
Two-thirds of climate-action ODA to Africa comes in the form of loans
- In 2022, DAC countries and multilateral organisations disbursed US$8.33 billion to Africa for climate action in the form of concessional financing – loans, grants and equity investments.
- Of this, US$5.4 billion (64.8%) came in the form of debt-generating mechanisms – loans. These loans are concessional (i.e. with low or no interest, and/or with longer terms to maturity); however, they ultimately have to be paid back, contributing to Africa’s externally held debt, which was US$1.12 trillion in 2022.
- Grants for climate action in 2022 were US$2.9 billion (34.5%) and the rest US$58.5 million (0.7%) was provided in the form of equity investments.
This focus on loans occurs even when we break climate action down into adaptation, mitigation or both. Mitigation activities are attractive to the private sector, and so loans are a common form of financing; adaptation, however, is carried out primarily through public investment and domestic budget, and so should attract grants.
Despite their limited contribution to the climate crisis, African countries borrowed more for climate action than they received in grants
Figure 1: Share of ODA for climate action in Africa by type of climate action and financing instrument, 2022
Over half of climate-action ODA to Africa targets adaptation
The African Union’s Climate Change and Resilient Development Strategy and Action Plan (2022–2032) reaffirms that adaptation and resilience-building remain Africa’s top priority. [15]
Slightly more than half (55.2%) of ODA from DAC donors goes specifically to adaption, Africa’s top priority
Figure 2: Share of ODA for climate action in Africa by type of climate action, 2022
- Over half of this concessional financing for climate action in Africa targeted climate adaptation – US$4.6 billion (55.2%) of the US$8.33 billion total.
- US$2.5 billion (29.6%) targeted mitigation and the rest, US$1.3 billion (15.2%), addressed dual objectives of both climate adaptation and mitigation. This breakdown is about the same even when looking specifically at loans.
- Although the majority of ODA prioritises adaptation, most (64.5%) of this adaptation funding, US$3.0 billion, comes in the form of loans (as shown in Figure 1).
45.2% of all adaptation grants were concentrated in just five countries
Both grants and loans for adaptation are concentrated in a handful of countries, including LDCs
Figure 3: The five largest recipients of grants and concessional loans for adaptation in Africa, 2022
- Adaptation is an integral part of sustainable development. We observe concentration of concessional financing for adaptation in a few countries. Niger, an LDC, is one of the top recipients of both grants and loans for adaption from DAC donors.
- Five African countries take 45.2% of total ODA grants meant for adaptation. A largely different group of five take 77.4% of concessional loans for adaptation and all, except Niger, are middle income.
African LDCs get most adaptation ODA as loans
33 of the 46 LDCs, as classified by the UN, are in Africa. In sub-Saharan Africa, more than half of countries are facing unsustainable debt burdens. Generally, the terms of ODA loans from DAC donors to LDCs have become increasingly stringent between 2015 and 2021. This period has seen rising interest rates, shorter maturity periods and a reduction in the average grant element of ODA loans extended to LDCs. Notably, it has been observed that the average interest rates imposed by EU institutions on LDCs are higher compared to those applied to other middle-income groups.[16]
The Paris Agreement[17] urges countries to take into consideration country-driven strategies:
“the priorities and needs of developing country Parties, especially those that are particularly vulnerable to the adverse effects of climate change and have significant capacity constraints, such as the least developed countries and small island developing States, considering the need for public and grant-based resources for adaptation.’’
The Paris Agreement
Of the US$8.33 billion of ODA for climate action in Africa, less than half (US$4.1 billion or 49.5%) is provided to LDCs, and half of that ($2.1 billion or 50.8%) comes in the form of loans. This proportion is higher when looking at adaptation finance specifically.
LDCs received more than half of adaptation ODA (56.9%) from DAC donors in the form of loans
Figure 4: Share of ODA adaptation financing by financing instrument in African LDCs, 2022
- 56.9% (US$1.6 billion) of ODA targeting climate adaptation in African LDCs comes in the form of loans.
IDA, the main financer of climate action in Africa, gave 83% of adaptation ODA as loans
The Sharm el-Sheikh Implementation Plan[18] encouraged multilateral banks to:
“define a new vision and commensurate operational model, channels and instruments that are fit for the purpose of adequately addressing the global climate emergency, including deploying a full suite of instruments, from grants to guarantees and non-debt instruments, taking into account debt burdens, and to address risk appetite, with a view to substantially increasing climate finance"
Sharm el-Sheikh Implementation Plan
In 2022, the World Bank’s International Development Association (IDA) was the largest single provider of climate finance to African countries, providing US$4.45 billion. This total is more than half (53.4%) of that provided by all DAC providers of climate action combined.
IDA provided US$2.8 billion in loans for climate adaptation in Africa, accounting for 83.1% of their adaptation total
Figure 5: Disbursements from the five largest providers of climate loans to Africa by climate action and instrument, 2022
- IDA’s focus on supporting adaptation efforts in Africa (71% of its overall funding) aligns to the continent’s priority (climate adaptation); however, its favoured instrument for financing adaptation is overwhelmingly loans (83.1%).
IDA used loans more often for climate-related projects than for non-climate related projects in Africa
The IDA notes that Africa is “at the heart of its global mission to end poverty on a liveable planet, representing more than 70% of IDA’s global commitments”.[19]
IDA is more likely to provide loans to climate-action projects than non-climate projects in Africa
Figure 6: Share of financing instruments employed by IDA for climate and non-climate projects in Africa, 2022
- Of the total IDA finance, 72.9% (US$11.9 billion) is non-climate related and the rest (27.1% or US$4.5 billion) climate.
- Comparing IDA’s concessional financing of climate projects to non-climate reveals that IDA employs loans for more climate projects (79.9% of total disbursements) than non-climate projects (62.7%).
Just five African countries accounted for 83.5% of IDA’s loans for adaptation in 2022
Figure 7: Five largest country recipients of IDA loans for adaptation, compared to the rest of Africa, 2022
- While 40 African countries are eligible to receive IDA resources, the majority of IDA’s financing goes to just a few of them. The five African countries that received the largest loans from IDA for climate adaption in 2022 were Kenya (23.8% of the total), Nigeria (18.9%), Niger (16.7%), Tanzania (12.6%) and Senegal (11.5%). Together they account for 83.5%.
- There is also a great concentration of grants – where the five largest recipients together accounted for 76.5%. These are Ethiopia (34.5%), Malawi (17.0%), Mozambique (14.7%), Madagascar (6.1%) and Somalia (5.1%).
- IDA’s assistance to Africa for climate does not necessarily align with need: Somalia, Democratic Republic of Congo, Chad, South Sudan, Central African Republic, Nigeria and Ethiopia – seven of the 10 countries in the world identified as most at risk of climate disaster[22] – are in Africa. Only 28.1% of IDA’s adaptation concessional financing went to these seven at most risk countries, with the majority to Nigeria (15.7%), Ethiopia (8.5%), DRC (2.3%), Somalia (0.9%), South Sudan (0.4%), Chad (0.2%) and Central African Republic (0.1%).
China is Africa’s third-largest provider of concessional climate loans, based on our estimates
In our assessment of concessional loans for climate action in Africa, we include China since it is the continent’s largest bilateral development lender.[23]
In total, Africa owed China US$5.7 billion from concessional loans in 2022. That year it provided US$275 million in concessional climate loans to Africa, making it the third-largest provider to the continent (behind only the IDA and France).[24][25]
71.3% of Chinese concessional climate loans to Africa were concentrated in five countries in 2022
Figure 8: The five largest African recipients of Chinese loans for climate action, 2022
- Just five African countries account for 71.3% of all climate-targeted loans to the continent. These are – Sudan (31.1%), Zambia (13.5%), Cameroon (9.2%), Guinea (8.8%) and Ghana (8.7%).
Chinese concessional loans for climate are more expensive than non-climate loans
In 80% of cases, the mean interest rate of Chinese concessional loans targeting climate is higher than the rates it provides for other concessional loans
Figure 9: Country average interest rates applied to climate and non-climate projects in Africa by China, 2022
- When comparing the interest rates of China’s non-climate-targeted and climate-targeted concessional loans, we find that in 80% of the cases where a difference exists, the mean interest rate for climate-targeted loans is higher than that for non-climate-targeted loans.
- Only 13.4% of DAC donors disclose their exact interest rates. For the 2022 climate loans from DAC donors for which we do have interest rate data, the average rate was 1.3%. This is about half a percentage point lower than the average Chinese climate loan (at 1.85%), but it is unclear whether the small sample of DAC loan rates we have are representative of all DAC loans. One reason why such a large proportion of DAC loans are missing interest rate data is that only bilateral donors report them. Multilateral donors, such as the IDA, do not report their interest rates to the OECD.
Key messages
Prioritising grant-based financing
Public, grant-based financing should be prioritised over loans and significantly increased in line with need. Grants should be particularly prioritised for African LDCs to further their adaptation efforts and avoid burdening them further with debt for climate action, as emphasised in the LDC Group Ministerial Declaration (2023).[26]
Developed countries should consider net transfer of finances to climate action in Africa in recognition of historical responsibilities. Donors should explore the potential for raising new and additional funds for climate action[27] in accordance with the Kyoto Protocol Art 11.2.a.
Refocusing IDA’s support for climate action
While African governments continue to call for more donors to contribute to the next round of IDA’s replenishment,[28] our findings show IDA’s climate finance has an overwhelming focus on loans over grants, concentrated on a few recipient countries. While the World Bank is just that, a bank, this focus on loans is adding a debt burden to the least developed African countries.
Given that IDA supports sub-Saharan African countries that are vulnerable to climate change but have a weak ability to cope with its negative effects, its support for climate action should be primarily grant-based, in line with the needs of these countries. It should cover as many eligible countries as possible, with a focus countries that are low income and at risk of climate disaster.
Attribution of fiscal effort: counting loans as Africa’s contribution
The attribution of fiscal effort of climate investments funded through loans needs to be reconsidered. Climate investments that ultimately must be repaid to a lender can arguably be considered as nationally determined contributions of the loan-recipient country. Donors who provide concessional loans should have this fiscal effort recognised, but the full cost of the loan should not be recorded as the donor’s contribution to the implementation of the Convention, and this should inform how the New Collective Quantified Goal (NQCG) on climate finance is measured
Reforming the global financial architecture
The inadequate volume of climate finance, coupled with questions about instruments, additionality and impact,[29] ultimately reflect the unfair and inequitable global financial architecture.
An equitable climate financing approach requires meaningful reform of the global financial architecture – which considers what is being counted, to whom investments are attributed, and which instruments and modalities are appropriate.
This is in line with the Decision -/CP.27 Sharm el-Sheikh Implementation Plan, paragraph 37, that called on “the shareholders of multilateral development banks and international financial institutions to reform multilateral development bank practices and priorities, align and scale up funding, ensure simplified access and mobilize climate finance from various sources and encourages multilateral development banks to define a new vision and commensurate operational model, channels and instruments that are fit for the purpose of adequately addressing the global climate emergency”.[30]
Enhancing transparency for accountability
Calls for changes in how climate finance is prioritised and delivered must be supported by more robust, consistent and comprehensive reporting and information on climate investments. This is the only way to measure how donor behaviour is changing, if these changes are leading to impact, and overall progress towards shared climate objectives, such as the New Collective Quantified Goal.
Donor reporting on ODA loans, for example, already requires reporting of terms and grant equivalent (including, for example, interest rates, payment structures and dates); however, climate finance reported under the Enhanced Transparency Framework[31] currently seeks only voluntary information on grant equivalent and no details of full terms on even a voluntary basis.[32]
Greater consistency in reporting based on agreed standards is needed in order to monitor how much new and additional climate financing developed countries are transferring to Africa and developing countries elsewhere.[33][34]
Methodology for determining climate relevance using machine learning
Approach
Before data for this analysis was downloaded from the OECD and AidData websites respectively, a model to determine a project’s relevance to climate, climate adaptation and/or climate mitigation was developed. A natural-language processing approach was taken to classify project title and description text into relevant categories. First, the ‘bert-base-multilingual-uncased’ model was selected based on the model’s performance on the languages commonly contained within the OECD DAC’s Creditor Reporting System (CRS). An additional 1% of unique vocabulary from the CRS was added to the model before fine-tuning. This gave the model a better understanding of the technical language contained within development and humanitarian projects and made training classifier networks built on top of the model embeddings more efficient. Lastly, the model was fine-tuned for three full passes of all titles and descriptions contained within the CRS.
Training
Once the fine-tuned base model was fully trained, training data was collected by taking project titles, descriptions, and metadata on each project’s climate relevance from the International Aid Transparency Initiative (IATI) data standard. IATI was chosen as the source for the training data both to avoid overfitting the exact text found within the CRS and because the IATI data contained a greater quantity of text. For projects where analogues could be found between the CRS and IATI, the combined CRS title, short description and long description fields had an average length of 470 characters, while the average length of IATI text was 1,068 characters. This data was used to train one binary classification model and one multi-class classification model. The binary model focused on identifying principal climate relatedness (either adaptation or mitigation as a principal objective) and achieved an accuracy of 91%. The multi-class model was tasked with differentiating climate adaptation from climate mitigation, as well as classifying projects as either significant or principal objectives. The multi-class model achieved an accuracy rate of 85%.
The Global Chinese Development Finance dataset
For AidData’s Global Chinese Development Finance (GCDF) dataset, candidate projects were first identified by their dates. A project was selected for evaluation if it contained a start date (planned or actual) during or prior to 2022 and an end date (planned, actual or loan repayment) during or after 2022. The binary classification model was chosen to evaluate the GCDF because the text was derived from media reports and differed in tone and content from the language typically used in project titles and descriptions. Model inference was run on the text in the GCDF to rank projects from most likely to be climate-related to least likely. A keyword search was then applied to manually review the results of the inference. The text was checked for the words and word fragments “solar”, “hydro”, “bio”, “ecolog” and “climate”, to determine whether to classify the project positively or negatively. Subjectively, the binary climate classifier did a good job with ranking the projects and matched up with the keyword search. One notable example of a project that had to be manually marked as negative despite a positive classification was a case in which the project described environmentalist opposition to the construction. We theorise this description yielded a false positive result because criticism of a project was not a feature commonly observed in the training data of the model.
The OECD CRS dataset
OECD CRS data was first filtered by projects that were classified as ODA, occurred in the year 2022 and had an African Union country or ‘Africa, regional’ as a recipient. Projects that were already screened by their donors for the Rio markers were kept as is. The multi-class classifier was applied to unscreened projects to determine the significant/principal climate adaptation/mitigation status of each project. A keyword search was also performed on the unscreened CRS data but given the wide diversity of donors a manually curated list of keywords was insufficient. Instead, the keywords were derived from the data itself according to term-frequency inverse-document-frequency for the projects that already had Rio markers. A total of 322 keywords were identified through this process. A project was considered a positive match if the model predicted a principal climate objective and one or more of the keywords was a match. A project was considered as “both” adaptation and mitigation only if both were identified as principal objectives.
