Purpose Social franchise chains have social goals rather than - or in addition to - commercial or profit-making goals. But are these social goals, disclosed by social franchisors, aligned with the Sustainable Development Goals (SDGs) and, if so, which ones? Design/methodology/approach The authors examine the disclosure of SDG-related information on websites of 69 social franchise chains operating in Africa. Findings The authors' main findings show that social goals disclosed by social franchisors are aligned with certain SDGs that are general in nature and not just sector-dependent, except in the case of education. Practical implications The authors' paper contributes to the practice by providing examples of the types and varieties of social goals social franchisors can pursue. Moreover, entrepreneurs might be encouraged to launch their franchise concept as franchisors who contribute to SDGs at an international, national or regional level or to join franchise chains as franchisees who contribute to SDGs at the local level. Social implications The authors' findings show the potential for social franchise chains in developing countries to target and contribute to achieving SDGs. Originality/value The authors' paper adds to the limited literature on SDGs and, more specifically, on the role of the private sector, in particular social franchisors, in targeting and achieving SDGs.
