The UN has selected five African countries—Guinea, Madagascar, Nigeria, Zambia and Zimbabwe—for its support mechanism for critical energy transition minerals. The initiative, announced in September, aims to help states better organize their resources, strengthen their regulatory frameworks and develop domestic value chains. Indonesia is also among the countries involved.
The mechanism is intended to provide public policy advice, legal and regulatory expertise, environmental and social safeguards, and support for local processing. No dedicated funding was announced at its launch. The challenge is therefore to distinguish technical assistance from direct investment: recommendations can improve project preparation, but they do not, on their own, finance a refinery, a component factory or a railway line.
Moving from extraction to added value
Global demand for copper, lithium, graphite, cobalt, manganese and rare earths is increasing with the expansion of power grids, electric vehicles, batteries and digital equipment. Yet extraction and processing are distributed very unevenly. Several African countries have significant resources, but a major share of refining and manufacturing takes place elsewhere. Added value, industrial jobs and skills are then concentrated in countries that process the minerals.
The UN mechanism seeks to support governments in developing strategies to capture more of these benefits. This may involve traceability rules, contract negotiations, training, shared infrastructure development or the establishment of social and environmental standards. Choices must remain suited to each mineral and market: the needs of a copper value chain differ from those of lithium or graphite.
Participating countries have different profiles. Guinea has iron ore and bauxite and is seeking to develop value chains around its resources. Madagascar has nickel, cobalt and graphite deposits. Nigeria has solid minerals but needs to organize its sector and infrastructure. Zambia intends to strengthen copper and cobalt processing. Zimbabwe relies notably on lithium, alongside its policies to increase local value addition.
Capital and technology remain decisive
Local processing requires investment, reliable energy, efficient logistics and market access. Companies that already have mining capacity, plants, technical expertise and offtake agreements have an advantage when launching projects. Chinese groups play an important role in some African value chains because they can combine financing, construction, processing and sales outlets in a single offering.
A regulatory advisory program can improve the investment framework and help states negotiate with better information. On its own, it does not change the balance of capital or technological capabilities. To turn assistance into results, governments will need to identify priority projects, mobilize financial partners and ensure that competition among investors improves the terms offered to producing countries.
Local content policy must also be realistic and measurable. Overly ambitious targets without training, financing or market access risk remaining theoretical. Progressive requirements—jobs, purchases from suppliers, skills transfer and processing developed in stages—make it possible to track results and adjust policies.
Reducing social and environmental risks
Mining can alter access to water and land, affect communities and put pressure on local infrastructure. So-called critical minerals are not exempt from these impacts. A global energy transition is socially sustainable only if the projects supporting it respect community rights, disclose their impacts and provide grievance mechanisms.
The UN plans to incorporate environmental and social safeguards into its support. Implementation will depend on national administrations, oversight institutions and operators' transparency. Rules must apply throughout the chain, from exploration to mine closure, and include waste management, water management and rehabilitation.
Traceability is another tool. Consumers and manufacturers increasingly seek information on minerals' origins and production conditions. Reliable systems can strengthen confidence in African exports. But they require verifiable data, oversight resources and cooperation among countries, companies and certification bodies.
The UN mechanism offers the five African states an opportunity to strengthen their mining policies amid competition for resources. Its effectiveness will be measured not by the number of reports produced, but by progress in funded projects, the share of local processing, job quality and the safeguards applied. The central question remains whether producing countries can negotiate partnerships that strengthen their skills and economies while preserving their development choices.
