This paper develops a tailored framework for the African Union to evaluate future energy demand and CO2 emissions under economic growth constraints. Its goal is to assess Africa's ability to increase GDP per capita and primary energy consumption while staying aligned with long-term emissions reduction targets. The model developed through this research uses Kaya Identity analyses to break down historical CO2 emissions into population, GDP per capita, energy intensity, and carbon intensity components. Emissions and energy data from recognized sources calibrate historical data and forecasts. For the broader African Union, we develop two scenarios: a business-as-usual (BAU) and a Paris-aligned case consistent with the Paris Agreement. Sensitivity analyses quantify how efficiency improvements and energy mix changes affect emissions trajectories. The findings show that growth in population and energy demand mainly drives emissions increases under the BAU scenario, causing CO2 emissions across Africa to grow steadily. Energy efficiency improvements alone are not enough to stop this trend. The Paris-aligned scenario highlights that significant reductions in carbon intensity through fuel substitutions and low-carbon energy source adoption can greatly slow emissions growth while supporting economic development. This indicates that Africa can boost GDP per capita and total primary energy consumption (EJ) while limiting emissions growth by reducing reliance on coal and traditional biofuels and strategically deploying low-carbon technologies like hydropower, wind, solar, and nuclear. The study emphasizes that emissions are most sensitive to changes in carbon intensity rather than energy demand itself, stressing the importance of policy-driven energy transitions and technology deployment for sustainable development. This work offers a quantitative, region-specific application of the Kaya Identity that explicitly links Africa's development goals with emissions mitigation. It presents realistic and affordable scenarios that expand economic and per capita energy use while reducing the climate impact. The framework clarifies each driver's contribution to emissions and provides practical insights for energy planning and transition strategies relevant to petroleum and the broader energy sector. A Kaya Identity analysis of Africa's five highest-GDP nations – Algeria, Egypt, Ethiopia, Nigeria, and South Africa – provides insight into how continent-wide findings can be amended to various economies. For each nation, four total forecasts, including one feasibility-adjusted BAU forecast and three high-energy implementation pathways, analyze increases in the African energy supply per capita through 2060. Through high-energy modeling, all five nations successfully reach a minimum target threshold of 50 GJ/capita by 2060, primarily through use of natural gas and renewable energy sources (RES) as bridge fuels away from unclean, primitive energy sources. Collectively, these five nations represent the engine of Africa's economic growth and demonstrate both traditional and modern economies. Due to their strong biofuel reliance (40%+ of current TES) Ethiopia and Nigeria provide the most realistic framework for the broader continent to emulate (traditional case). Algeria, Egypt, and South Africa represent more modern, industrialized economies whose focus through 2060 primarily involves leveraging existing hydrocarbon reserves and infrastructure, further diversifying energy mix in accordance with prescribed renewable targets, and phasing out coal dependency. Although more underdeveloped economies (e.g., Ethiopia) are largely Paris-compliant, case studies on required GDP growth restrictions, emissions intensity shifts, and energy efficiency demonstrate that strict conformance to enumerated NDC 3.0 and/or net zero goals is infeasible long-term and a gradual transition into low carbon technologies is more appropriate to avoid unfairly impeding African Union development.
