Because the notion of sustainability is not well defined, we are usually left with trying to do the right thing, but not really sure it will help. Connecting the dots between these two is not easy. Manufacturing and sustainability operate at different scales, and different time frames. Manufacturing is about gratifying people today, while sustainability is about not interfering with a future generation’s ability to provide for themselves. In this talk we look at how other large systems disciplines look at sustainability and then try to connect the dots back to manufacturing. The general game plan here is to articulate a measurable framework for sustainability, and then see how manufacturing compares. Some key concepts come forward, such as differentiating between what promotes human well-being today, versus what promotes it for the future. This line of reasoning excludes several well known aggregate measures of human well-being from being measures of sustainability (e.g. Gross Domestic Product, and Human Development Index). When applied to manufacturing, other cherished notions also fall as we sharpen our view on what is sustainable. If we focus only on energy or carbon, we can be yet more quantitative concerning the connection between actions at the manufacturing level and responses at the global level. Thermodynamic limits come into play and new strategies emerge. Some themes we touch on include collapse and renewal, foresight, aggregation and substitution, institutions, and efficiency and rebound. Manufacturing examples are taken at various scales, from products, to the sector as a whole.
