As it is widely known, early design stages are key to an efficient overall design process, here is were the most
substantial changes can be made with less negative impact to the design cycle. Therefore, the inclusion of
sustainability factors at the early stages of the design will allow the creation of environmental friendly products,
and better control of costs and design cycle duration from the start. Thus preventing high costs corrections of the
design, or costly secondary processes at the end of the product lifecycle. Traditionally, early concept evaluation
does not consider sustainability in a holistic way; sustainability analysis tools such as Life Cycle Analysis (LCA)
and geometry-based carbon footprint calculation are typically applied at later stages of design when full geometric
information is present, or full material mass and manufacturing processes has been completely identified. Such
requirements limit the capability to integrate sustainability at the early stages of design in a scientific and organic
manner. In this work, a methodology is proposed to deal with those limitations by an early estimate of
sustainability impact based on product functionality.
