South Africa requires significant investment to transition to a low-carbon economy and resilient infrastructure, especially in energy and water sectors. Heavily reliant on coal and facing increasing water scarcity due to climate change, South Africa’s shift towards sustainability is crucial for long-term environmental and economic stability.

With the support of AFD, the University of Cape Town (UCT), Development Bank of Southern Africa (DBSA), Presidential Climate Commission (PCC), National Treasury, and the Centre for Sustainability Transitions of Stellenbosch University are developing a model that evaluates the macroeconomic impacts and various policy options and financing mechanisms for transitioning South Africa's water, energy, and food (WEF) systems in response to climate challenges. 

This project falls under the “South Africa – Towards Inclusive Economic Development” (SA-TIED) initiative, a research and policy programme aimed at fostering inclusive economic growth in South Africa.

The GEMMES programme is developing a general theoretical model on the one hand, and national models applied to concrete cases and adapted to the characteristics of each country on the other, including the GEMMES South Africa model. 

The GEMMES South Africa project aims to:

• Analyze the macro-financial impacts of transitioning to renewable energy, ensuring water security, and maintaining food sustainability;
• Provide policymakers with insights and forecasts to inform decision-making and long-term planning for economic growth, employment, and climate resilience and more specifically provide insights into the macroeconomic effects of climate-resilient investments up to 2050;
• Enhance understanding of the vulnerabilities and opportunities in South Africa’s transition by integrating macro-financial feedback loops into structural change analysis;
• Foster sustainable development and mitigate environmental risks, contributing to long-term economic stability and improved quality of life;
• Promoting public policy dialogue on South Africa's low carbon transition.

In addition to its specific transdisciplinary approach, which makes this project one of the few to integrate the notion of strong sustainability, the originality of GEMMES lies in its consideration of macro-financial imbalances and the impact of the low-carbon transition on all elements of the balance of payments.

GEMMES South Africa builds on UCT’s SATIM-GE energy transition model incorporating macro-financial feedback loops, which provide critical insights into the country's economic vulnerabilities and investment opportunities during this transition.

GEMMES South Africa is built in partnership with local authorities and research institutes to guarantee that the tool is coherent with the country's needs and to assure that the partners are capable of using and improving independently. It will account for:

• the dynamics of interest and exchange rates and their impact on private investment and employment;
• the fiscal and macro-financial constraints;
• different dynamics between banks and non-bank financial institutions;
• the capacity of public investments in green infrastructure to drive a new ecological transformation plan;
• and, the impacts of climate changes. 

The GEMMES South Africa project anticipates several key publications, including:

• A presentation of the specificities of GEMMES-South Africa and its baseline simulations;
• The macro-financial implications of infrastructures investments;
• The macro-financial implications of climate change impacts.

These papers will provide valuable insights into the project's findings and contribute to ongoing discussions in the field.

At this stage, while the project is still in its early phases, it is expected that integrating macro-financial feedback loops will play a significant role in shaping effective policies and investment strategies. As the project progresses, ongoing stakeholder dialogue will be crucial in refining these concepts and addressing future challenges in the transition process.

• Demand-induced transition risks in South Africa (December 2023)

South Africa remains one of the most unequal countries in the world. The country’s high-income inequality is driven primarily by extreme differentials in the labour market, where over 30% of the labour force is unemployed and earns zero income (Leibbrandt et al., 2010; StatsSA, 2024). Reducing unemployment is therefore at the heart of South Africa’s social and economic challenges, and is key to lower the level of inequality. 

Coal is an important industry in South Africa and is central in the just transition. Rough estimates of total employment in the coal value chain alone are close to 200,000 – roughly 1.2% of total employment – while the contribution to output sits at 5.4% of growth domestic product (Makgetla et al., 2021). Moreover, the coal industry is highly geographically concentrated and underpins a large share of local and regional economic activity in certain areas, particularly localities within the Mpumalanga province.

In this regard, the potential negative employment impacts of a transition away from coal, and toward low carbon energy production, presents a significant socio-economic challenge for a country still dealing with the vestiges of apartheid. It is thus critical that the risks associated with these potential adverse employment effects are managed to ensure that inequality is not worsened by an unplanned transition.

This work is also part of AFD's dialogue with the South African authorities on the just transition and the identification of reforms to be implemented to ensure an inclusive transition.

There is currently a limited understanding of how many workers are likely to be affected by a transition away from coal; how these workers vary by age, skill, or income level; what an effective social protection policy package for such workers would involve; how much a given basket of policies is likely to cost; and the financing options available. Yet, these are crucial elements in designing and implementing policies that limit the negative social and economic effects of transition and prevent potential increases in unemployment and inequality.

This project aims to make two primary high-level contributions:

1. First, it will count and profile existing workers in coal and related industries using reliable, spatially sensitive microdata. This includes an analysis of employment, wages, and wage inequality;
2. Second, it will propose a basket of social protection policies tailored to the identified worker profiles, with attendant modelled cost estimates, and potential financing options. This includes a focus on the wage inequality implications of various policy scenarios that highlight the importance of a just transition in South Africa.

The research project has four main components that will encompass the following analytical areas:

1. The utilisation of tax data to accurately identify at-risk employees in coal mining, coal-based electricity generation, and coal-adjacent industries, locating them spatially across the country. This will provide a reliable estimate of the number of direct and indirect coal industry workers at risk of being adversely affected in a shift away from coal.
2. The production of detailed gender, age, and earnings profiles of the identified at-risk workers in the sector. This exercise is anchored around worker earnings and will be used to identify sub-groups, or cohorts, of workers who will require different forms of protection and support based on their existing skills, earnings, and age profile. The earnings data will in addition be utilised to examine inequality dynamics within the coal value chain and between coal value chain workers and those employed in mining generally and in the formal economy as a whole.
3. Using these worker profiles to provide a framework of suitable policy options for the different cohorts in order to develop a comprehensive social protection response. Policy options would include individually assigned combinations of interventions such as early retirement packages, grants, and skills development. Furthermore, the study will provide a comprehensive overview of the various social protection policies available in South Africa and determine whether they could apply to affected workers.
4. Examination of scenarios for declining coal employment and model a series of associate cost estimates for the various policy response options. This includes modelling possible policy scenarios over the full-time horizon of existing employees. The result is a costed picture of the implications of the just transition policy for South Africa’s coal sector, that includes a discussion of potential public finance options. The findings will also shed light on potential inequality outcomes to emerge from different just transition policy scenarios.

The project resulted in two research papers, available below: 

• Counting and Profiling Coal Mining Industry Jobs (July 2025): 

Subcontracted employment within the coal mining industry has grown, now constituting nearly half of all jobs. The workforce is relatively young, requiring transition policies that prioritize skills development and job placement. Men comprise the bulk share of employees in the coal mining industry, although female participation has risen over time. Coal mining industry jobs are relatively well paid, with the average coal miner wage surpassing that of the average formal sector worker, thus making income support for displaced workers financially burdensome. Wage inequality within the coal mining industry is lower than wage inequality within the broader formal sector economy. Thus, should coal miners transition from jobs in the relatively low inequality coal mining industry, to jobs in high inequality industries, then it is possible that overall inequality will rise.

• Ameliorating the Consequences of Coal Job Destruction - A Just Transition Policy Matrix Approach (October 2025)

Ensuring a just energy transition in South Africa requires supporting workers to absorb the negative shocks of structural change. Central to this is the design of a comprehensive social protection package for coal mining workers. This paper proposes the “just transition policy matrix” approach, which uses micro data to tailor policy responses to the needs of different groups of at-risk workers. 

Temporary income support dominates expenditure in all scenarios, followed by education and training. Existing policies can be leveraged to support displaced workers. Nonetheless, when applied to coal workers, funding gaps remain, requiring additional fiscal resources and implying a substantial rise in social protection spending.

The energy transition is a challenge and a necessity for Mexico’s economic transformation as, on the one hand, the country spends 7.6% of its GDP on fossil fuel subsidies and, on the other hand, in 2020 it was estimated that the economic impact of climate disaster increased by 202%. In order to achieve a successful energy transition and secure a sustainable growth path, Mexico needs to modernize its energy sector, reduce reliance on fossil fuels, and ensure sustainability. However, it is necessary to start from the territory, involving communities in the co-construction of resilience and the strengthening of local productive chains. Community and cooperative models play an essential role in promoting the creation of collective businesses managed in a democratic and solidarity-driven manner.

An example of just transition opportunities are energy cooperatives. They are a clear and promising model that involves local communities in the production, distribution and consumption of renewable energy, promoting decentralization and democratization of energy, especially in those territories historically and systematically excluded.

However, research conducted in Mexico during the first phase of the Research Facility on Inequalities showed low wealth sharing and limited social mobility in the country. In this context, it is necessary to address the just energy transition from an intergenerational social mobility approach and a social perspective to ensure benefits for the whole society. 

This work is also part of AFD's dialogue with the Mexican authorities on options for diversifying the economy and reducing inequalities.

In partnership with the Centro de Estudios Espinosa Yglesias (CEEY) and in collaboration with the National Institute of the Social Economy (INAES), this research project aims to develop a conceptual and analytical research input for a better understanding of the role that renewable energy cooperatives can play in reducing inequality and increasing social mobility, and how they can be financed. 

This input will:

• Conceptualise the just energy transition approach in the area of existing structural inequalities;
• Make a diagnosis from the perspective of intergenerational social mobility, as well as from the perspective of social and solidarity economy, and its relevance in the framework of just transitions, in order to establish identification criteria, social selection and prioritisation of projects;
• Use this diagnostic to propose criteria for the identification and selection of projects that prioritise the populations with the greatest disadvantages of origin (with the least space for social mobility), given the requirement of «no losers» of the just transition;
• Review and articulate technical issues related to decentralised energy and distributed generation, given their importance in the social economy in the just energy transition;
• Review the current INAES projects related to the subject in order, where appropriate, to guide the construction of identification and selection criteria.  

The research team will first conduct an exhaustive review of literature focused on environmental justice, climate justice, social mobility applied to environmental justice and intergenerational environmental justice. The literature will be analysed from the perspective of the energy transition and the intersection of these issues.

Based on this review of literature, researchers will develop a conceptual framework to understand the just energy transition in the field of current structural inequalities. It will also explain how this conceptual framework can be relevant for public policy decision-making.

The research team will also identify information gaps and research needs, with a special focus on the study of just energy transitions.

Trade integration has been very beneficial for Latin America and the Caribbean (LAC) over the past 30 years. However, multiple crisis (the financial crisis of 2008, the Covid-19 pandemic, the climate crisis, etc.) have generated uncertainty about the future of the multilateral trading system. For example, the Covid-19 pandemic highlighted the fragility of certain value chains due to the vulnerability of a system in which factories are located at the other end of the world from where these goods are consumed. All this is leading to reconfigure global value chains, which tend to shorten, becoming less global and more regional – a phenomenon known as the “nearshoring model”. This new context creates an opportunity for LAC countries, and especially for Mexico, which identify themselves as the best alternative for the relocation of value chains under the nearshoring model.

Historically, the Mexican North-Central states have benefited most from the processes of integration into global value chains. This is natural, since it is where the manufacturing export base is located due to its proximity to the United States. On the other hand, the South-South-East of the country presents historical lags that make it significantly difficult to integrate it into global value chains and, therefore, to take advantage of change in the current international context.

In this regard, it is imperative to design strategies to take advantage of the opportunity presented by the nearshoring phenomenon, taking into account the particular problems of each region. This two-speed strategy is essential to define public policy interventions that can achieve more equitable regional development.

This research project complements the work carried out by the Extension of the Research Facility on Inequalities in Mexico on the national care system and on the redistributive impact of environmental policies.

This project aims to deepen the study of the phenomenon of relocation of global value chains to Mexico, recognising the challenges and opportunities it generates:

1. First specific objective: To present a proposal to overcome one of the most critical bottlenecks identified by the productive sector, which is electricity generation. It is suggested to close the investment gap in electricity in the short term, through investment in distributed generation with solar panels, as well as exploring sustainable and equitable options, with a particular focus on the State of Nuevo León (North of the country).
2. Second specific objective: To identify economic sectors with potential to benefit from the phenomenon of relocation of value chains and to address existing gaps in the formation of talent and human capital, emphasising social inclusion and gender equity. This will include a detailed analysis for the states of Oaxaca and Veracruz (South of the country), aiming to develop skills in emerging and traditional sectors, and prepare the workforce to take advantage of opportunities in the medium and long term.
3. Third specific objective: To develop a strategic plan for the implementation of a portfolio of solutions based on the recommendations identified in the first and second specific objectives.

• First specific objective: Scenario analysis will be used to measure the gap between demand and capacity for electricity generation. Solar distributed generation capacity scenarios will use Geographic Information Systems spatial analysis tools, while the estimates on the redirection of subsidies will be taken from official public sources.
• Second specific objective: Generated using a combination of international and national databases, economic metrics will serve to identify opportunities to boost productive diversification. A preliminary analysis will suggest industry clusters to prioritize. This will allow to select economic sectors with the potential to trigger industrial development, through interventions in the field of talent training. Talent gaps will then be identified through quantitative analysis. This cabinet analysis will be complemented with qualitative information (interviews, focus groups with key actors…).
• Third specific objective: The strategic plan will follow a mission-oriented policy approach, including a detailed action plan to be presented to the Mexican Federal Government. The plan will consist of a map of possible executing units within the federal, state and/or municipal governments, an analysis of the regulatory and institutional constraints that the plan could face, as well as strategic alternatives to overcome them.

The project resulted in 3 research papers: 

• Gaps in Human Capital and Labor Demand in Oaxaca
• Redesigning Electricity Subsidies for Distributed Generation in Mexico: A Fair Transition Model Applied to Nuevo León
• Institutional Implementation of In-Kind Subsidies for Distributed Generation: Multi-Level Governance and Policy Design in Nuevo León
