This document summarizes a master's thesis that provides a step-by-step guide for incorporating environmental aspects into the furniture design process. The guide outlines 7 steps for a sustainable design strategy: 1) Understanding the product's use context, 2) Overviewing environmental impacts, 3) Creating an environmental profile, 4) Mapping stakeholders, 5) Selecting materials and processes, 6) Developing an environmental concept, and 7) Establishing an environmental strategy. The thesis aims to help designers implement sustainability practices from the early design stages through a clear process. It also presents a pilot project applying the proposed systematic approach.
