Irreplaceable Goods: Bridging Sustainability and Intergenerational Sufficientarianism

Abstract

In 1987, the Brundtland Commission urged nations to improve present conditions without compromising the ability of future generations to meet their needs. Against the background of this appeal for sustainable development, there is a call for intergenerational justice, under a sufficientarian framework. Despite their strong relation, we claim that, to some degree, intergenerational sufficientarianism disregards relevant sustainability notions. This neglect undermines intergenerational sufficientarianism in the context of sustainability, here operationalized as sustainable development. In response, we propose the concept of irreplaceable goods as a necessary bridge between the two frameworks. Simultaneously, we stress the need for scholars to consider sufficientarianism as a valid alternative to egalitarianism for achieving resource justice. To harmonize intergenerational sufficientarianism and sustainability, we firstly delineate sustainability theoretical notions that influence fair distributive futures. Secondly, we incorporate those sustainability constraints into the conceptual background of intergenerational sufficientarianism. We also establish the concept of irreplaceable goods as a pivot and anchor for further theoretical development on the sufficient well-being of future generations. Finally, we discuss the implications of this concept in terms of expenditure and investment by contemporary people. With the proposed adjustments, we advocate that intergenerational sufficientarianism is a robust framework to deliver just futures.
