African climate think tanks, regional officials and government envoys met in Johannesburg on 9–10 October for a G20 Expert-Level Climate Informal Consultation convened by AUDA-NEPAD and Kenya’s Office of the Special Envoy for Climate Change. Their message was direct, that if the G20 is serious about a global transition that leaves no region behind, it must open decision-making spaces, accelerate institutional reform and deliver finance and technology on terms that reflect Africa’s development priorities.
The consultations surfaced a practical problem that has become policy orthodoxy in African capitals: ambition without finance is a slogan, not a strategy. Experts in Johannesburg reiterated that Africa’s climate agenda is inseparable from its development agenda, from jobs and industrialization to food security and debt sustainability, and asked the G20 to commit instruments that are concessional, predictable and tailored to the continent’s circumstances. The statement from the forum frames those needs around four complementary asks: policy space for differentiated transitions, scaled concessional finance for adaptation and mitigation, technology transfer and local manufacturing for green industries, and reform of global financial and debt rules to reduce the cost of capital for African borrowers.
The arithmetic behind the urgency is stark. Recent assessments place Africa’s climate investment needs to 2030 in the order of $2.5–$2.8 trillion, while tracked climate finance flows to the continent remain measured in the tens of billions annually, not the trillions required to change fundamentals on the ground. The Climate Policy Initiative documents that flows were roughly $44 billion in 2021/22, a four-to-five-order magnitude gap compared with aggregate needs. At the same time African governments are servicing growing debt burdens that eat into fiscal space: the African Development Bank and other analysts report debt service and related pressures in the hundreds of billions, a structural constraint that makes concessionally and currency-risk mitigation non-negotiable for many projects.
What makes Johannesburg more than a talking shop is timing and leverage. The African Union now sits at the G20 table as a permanent participant and South Africa holds the G20 presidency for 2025, creating a window in which African priorities can be elevated from addenda to agenda items. This opens practical pathways: pilots of locally anchored Just Energy Transition Partnerships, compacts on critical minerals that pair extraction with local manufacturing, and regional instruments that underwrite cross-border infrastructure and pooled procurement, all schemes that were discussed in Johannesburg as forms of partnership, not charity.
The consultation’s specificity is its strength. Calls for a Compact on African Critical Minerals, for example, are not abstract protectionism; they are a policy response to a simple market reality: Africa supplies a rising share of metals and minerals for batteries and renewables yet captures only a small share of downstream manufacturing value. Without binding commitments on technology transfer, local content targets backed by finance and guarantees, and clear timelines for capacity development, African producers risk remaining raw-material suppliers while the higher-value green supply chains are located elsewhere. The Johannesburg experts argued for negotiated roadmaps that tie export access or concessional finance to verifiable milestones in local processing, skills development and environmental safeguards.

Likewise, the finance conversation in Johannesburg moved beyond headline pledges to instruments that matter in practice: longer maturities for public borrowing, partial credit guarantees that reduce bank risk premiums for private developers, currency-hedging facilities to protect project cashflows, and outcome-linked concessionally that lowers cost of capital if projects deliver agreed social and emissions targets. These tools respond to an immediate investor calculus: bankable cashflows matter more than good intentions. Several participants urged G20 members to scale blended finance windows and expand guarantees routed through regional development banks, mechanisms that can convert policy signals into signed contracts.

Adaptation received equal attention. African experts made the case that translating National Adaptation Plans into investments requires predictable grant finance for public goods, flood defences, climate-smart irrigation, resilient health systems alongside instruments that lower private capital costs for decentralized renewables and resilient agriculture. The Johannesburg forum stressed that adaptation must not be an afterthought to mitigation; for many African economies the near-term fiscal risk is climate damage, not marginal emissions.
The consultations also surfaced a governance imperative. African participants asked the G20 to support reforms that democratise global rule-making on tax, debt and trade so that African governments can both raise fair domestic revenue and access international capital on equitable terms. Institutional reform, they argued, is the precondition for converting external finance into durable domestic capacity ,procurement, stronger regulators and transparent benefit-sharing systems that ensure communities see and accept the returns of projects.

Johannesburg concluded with a pragmatic posture; Africa does not reject responsibility for emissions, but it insists on differentiated pathways and the means to follow them. The consultation’s test now is follow-through, whether the G20 translates dialogic statements into concrete instruments, timelines and financing lines that can be channeled through African institutions, and whether African governments reciprocate with credible pipelines and governance reforms that make investment inevitable rather than speculative. The outcome will determine whether the next five years produce durable pipelines of climate-aligned infrastructure across the continent, or another round of ambitious rhetoric with insufficient capital to back it.
