Aluminium du Cameroun (Alucam) was set up in 1957 as a subsidiary of the French aluminium group Pechiney. Since its creation, the Alucam plant has systematically applied policies that simultaneously integrate economic, social and environmental aspects. The originality of our contribution is that we describe a case where the three elements that make up corporate social responsibility (economic, social and environmental) are intertwined. Although this combination of elements had not formally materialised at the time, the case examined shows early awareness – comparatively ahead of its time and relatively well combined between the 1950s and the 1980s – of the three dimensions of corporate social responsibility.
