The manifesto shows how Best UP, which many recognize as a pioneer in the area of sustainable living, advocated a systemic approach from the very outset. Point 9 of the manifesto, cited by Ezio Manzini at the presentation of the Association at the Triennale, declares that companies of the future "are those that generate positivity,” and that “they are those who build a sustainable economy whose strength lies in its ‘relationship capital.’” Looking back across the space of so many years, I can obviously see certain aspects that should have been emphasized more, beginning with the importance of circularity in manufacturing processes, from the extraction of raw materials and the sourcing of secondary materials to distribution, maintenance, repair and reuse. We ought to have underscored more boldly the fact that nothing loses value in a circular economy in which products are accompanied “from the cradle to the cradle,” so to speak. There should have been a stronger commitment to the use of renewable energy. As we have seen, the resources of the planet are not infinite, so we need to transition as quickly as possible to non-fossil fuels. As regards our living spaces and environments, we have various different options depending on the climate of our location and the resources it has to offer. Another crucial necessity that warrants our unstinting effort is the drastic reduction of waste, which needs to occur upstream, at source, where it is created. We need a total paradigm shift that will decisively change our behaviour as individuals for once and for all.
