Life cycle analysis (LCA) is often used to compare the sustainability of product concepts, but how our intuition factors into analysis and innovation is rarely considered. Intuitive evaluations of sustainability by designers not only help scope LCAs, but can be a dominant force in early stage decision making and concept creation. To elicit intuitive responses from experts, eight environmentally conscious products were presented to 22 designers as part of a professional workshop survey. Participants rated their own experience in design and sustainability and rated the sustainability and innovativeness of each product from low to high. These ratings are compared with available LCAs and environmental impact information. The results indicate that self-perceived expertise in sustainability does not significantly change perception of the sustainability of products and that sustainability ratings and innovativeness ratings were moderately correlated.
