At first thought, sustainable design seems to be in direct opposition to the nature of the consumer society that industrial designers and interaction designers strive to enhance, and is thus a challenging subject for designers to come to grips with. Organizations and processes are emerging that allow the design team to understand and analyze the implications of their designs on sustainability, including the use of materials, energy, and the full lifecycle from “cradle to cradle.”7 This knowledge is still immature, making design for a sustainable planet an intuitive rather than exact science so far.The designer can intuitively synthesize a complex set of requirements, but the right information has to be there to draw on. Sustainability is still at the level of complexity where the science is not yet well established.
