As mobility and transport activities declined during the COVID-19 lockdowns, transactions and operations became increasingly dependent on digitalisation. This shift reduced the need for carbon-emissions-intensive fossil-fuel-based transportation. Using a panel of thirteen (13) Southern African Development Community (SADC) countries over the period 2002–2021, the analysis captures financial inclusion through indicators of ATM density and commercial bank accessibility, while digital inclusion is measured using mobile phone subscriptions and internet penetration. On this basis, it investigates the effects of (a) financial and (b) digital inclusion, and (c) the moderation of financial and digital inclusion on transport-related carbon emissions. Employing the Panel Two-Stage Estimated Generalised Least Square (EGLS) analysis on data obtained from the World Bank database and Our World in Data, the findings reveal statistically significant outcomes. Increasing ATM accessibility, commercial bank branch accessibility and mobile phone subscription rates are associated with reduced transport-related emissions. In contrast, enhanced internet access does not contribute to transport-related carbon emissions. Moderation analyses further indicate that the interaction of the accessibility of ATMs or commercial bank branches with internet access do not lead to a further reduction in carbon emissions than the individual ones but might have a slightly opposing direction (that still do not annihilate the individual effects). Findings show that only the moderation of ATM accessibility and mobile subscriptions reduce transport-related carbon emissions further than the individual effects. Taking the economic development of most SADC countries in the last 20 years into account, the study recommends strategic investment in advanced digital innovations, particularly linked with mobile devices, to strengthen digital banking efficiency and improve customer service while supporting emission-reducing pathways.
