Can Cleantech contribute to a sustainable future?

Abstract

Cleantech can be described as a diverse range of products, services or processes using technologies that optimize our use of natural resources and minimize environmental impacts. In this paper we explain that Cleantech can be seen as an implementation towards (weak) sustainability. This because proponents of weak sustainability believe that technological improvement can overcome any resource constraint. Cleantech can contribute towards a sustainable future but Cleantech is not the equivalent of a sustainable future because Cleantech activities do not solve the question of absolute scarcity. On the other hand, Cleantech can be an important step if we move from system optimization towards system innovation and transition. To achieve maximum diffusion and valorization of environmental technologies, we therefore distinguish the “Cleantech approach”. In this value-oriented approach all Cleantech key players (companies, research centres, consumers, government and investors) search for value in a spirit of cooperation.
