Aesthetics are a key-factor in Product Design, and can be discussed from several points of views. This paper looks at sustainability
to summarise relevant matters concerning aesthetics in Sustainable Product Design (SPD) as: general discussions; special aesthetics;
and aesthetic criteria. To illustrate how the products aesthetics can influence their sustainability, it is necessary to take
note of the role of aesthetics in product unsustainability. After reviewing the related references to SPD and its backgrounds
– including Sustainable Development, Green Design, Life Cycle Design and Eco-design – the authors have processed and categorised
the relevant keywords to aesthetics into seven aesthetic attributes through graph theory. These aesthetic attributes, which
are: ‘aesthetic durability’; ‘aesthetic upgrade-ability and modularity’; ‘simplicity and minimalism’; ‘logicality and functionality’;
‘natural forms and materials’; ‘local aesthetic and cultural identity’; and ‘individuality and diversity’, seem effective
for promoting products sustainability.
