ABSTRACT
This chapter describes the Methodology for System Design for Sustainability (MSDS), together with its tools for system design for sustainability. This is one of the results of the Learning Network on Sustainability (LeNS) project, integrating and updating what was produced in those projects together with other tools linked to other approaches to system design for sustainability. The chapter discusses several tools that may be used to support the various stages of the MSDS. The tools can be classified into two basic groups: sustainable system design steering tools; and stimulus and support tools for the generation of ideas and strategic to system design. The MSDS method aims to support and orient the entire process of system innovation development towards sustainability. The basic structure of MSDS consists of five main stages: strategic analysis; exploring opportunities; designing system concepts; designing a system; and communication.
