Unveiling the impact of green and sustainable supply chain practices in decarbonizing the transport sector in Sub-Sahara Africa: A comparative review

 The global transport sector accounts for nearly one-quarter of energy-related CO₂ emissions, with road transport contributing the largest share. While much of the decarbonization discourse focuses on developed economies, Sub-Saharan Africa (SSA) faces unique structural, infrastructural, and policy constraints that shape its transition pathway. The study adopted a systematic literature review design. The search focused on peer-reviewed journals published in Scopus and ScienceDirect databases from 2016-2026. Four African countries were purposively selected to ensure regional representation. Results reveal an uneven geographical distribution pattern of scholarly focus of the SSCM and/or GSCM across SSA with South Africa dominating. The sectoral distribution reveals freight transport dominates at 46%, a significant proportion given that freight logistics constitutes the backbone of SSA's supply chain infrastructure while simultaneously representing one of the sector's largest sources of GHG emission. Maritime transport accounts for 14%, reflecting the strategic importance of SSA's major trading ports, including Durban, Cape Town, Lagos, and Luanda. Green procurement, low-carbon transport modes, and renewable energy integration each appeared in 13 studies while sustainable warehousing ranked lowest. Road freight pharmaceutical distribution in Southern Africa recorded emission intensities ranging from 239.57 to 6,156.80 gCO2e/t-km. The study concludes that six major GSCM practices were identified across SSA's transport sector, quantitative evidence confirms that meaningful emission reductions are achievable. Infrastructural deficits, coal-dependent electricity grids, weak and inconsistent policy frameworks, and the limited financial capacity in SSA logistics constitute the most barriers to GSCM adoption. Prioritizing digital logistics transformation is recommended for accessible and cross-cutting entry point into GSCM adoption, given its lower capital requirements and demonstrated co-benefits for both emission reduction and operational efficiency.
