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.

Indonesia’s commitment to carbon emission reduction is aligned with its global responsibilities under the Paris Agreement. The country is also one of the 52 national jurisdictions in the world that have established carbon pricing regulations (World Bank, 2023). The primary goal of carbon pricing instruments implementation is to support Indonesia in achieving its Nationally Determined Contribution – which are commitments that countries make to reduce their greenhouse gas emissions as part of climate change mitigation.

In this context, the Government of Indonesia intended to introduce carbon pricing instruments on a voluntary basis from 2021 to 2024, with a shift to mandatory enforcement expected by 2025. Despite its modest start, the introduction of this tax marks a considerable advancement in Indonesia, particularly given the few low and middle income countries that have implemented a carbon tax. 

Using carbon pricing as a method to foster a decarbonised economy is a significant policy instrument, yet it can lead to uneven burdens across different societal groups. These measures, while environmentally beneficial, may inadvertently promote inequality. If these disparities are not addressed, the push towards global decarbonation could be hindered, achieving less impact or imposing uneven costs.

Using an analytical tool from Commitment to Equity Institute (CEQ Institute), this research project aims to improve the design of policies that can both deliver environmental goals whilst reducing the distribution burden, by ensuring a just transition.

This research project complements two studies carried out by the EU-AFD Research Facility on Inequalities in collaboration with the Indonesian government on Marine Protected Areas development policies and the production of a diagnostic on inequalities in the country.

The general objective of this research project is to assess the environmental (emission) and welfare-distributional effects (indicators of poverty and inequality) of trading and non-trading instruments (carbon price and revenue). Specifically, the study aims to incorporate heterogeneous cost and impact assessments across the archipelago of Indonesia. 

The study will focus on the impact of carbon pricing and other indirect fiscal instruments (taxes and subsidies) combined with direct taxes and social transfers that can assist in the mitigation of these instruments on welfare distribution and environment.

In order to design more effective policies that meet both environmental and distributive objectives, CEQ Institute has developed an analytical tool using micro data on household characteristics, behavioural science and a data analytical tool known as microsimulation modelling. It is an ex ante planning tool taking micro units, such as households, and simulating policy changes in advance of policy implementation. 

The framework incorporates the following discrete analytical dimensions: 

• Methodological frameworks to model the distributional impact of fuel related fiscal policies;
• An Input-Output framework to track the indirect impact of carbon prices;
• Behavioural implications of alternative environmental challenges using a demand system;
• Identifying just transition solutions using social protection instruments.

The dataset integrates two primary sources: the 2016 Table Input Output from the Central Bureau of Statistics (BPS) and the 2022 National Socioeconomic Survey (SUSENAS). Data and information from the Indonesian Directorate General of Taxes and from various relevant ministries are also used to conduct the study.
