The efficiency of a performance compares outputs (products + profits) with inputs (raw materials + investments). But eco-efficiency, instead, relates the satisfaction provided by products and services, with the environmental harm they produce during their entire life. It pursues sustainable development as the ultimate objective.
Eco-efficiency means applying strategies to produce goods and services to provide benefits to companies and please consumers, with environmental preservation as a parallel target. Therefore, new ways to proceed doing the right things right is a must. Creativity and innovation play key roles, being essential in our ecodesign.
