The Handbook of Sustainable Innovation maps the multiple lineages of research and understanding that constitute academic work on how technological change relates to sustainable practices of production and consumption. Leading academics contribute by mapping the general evolution of this academic field, our understanding of sustainable innovation at the firm, user, and systems level, the governance of sustainable innovation, and the methodological approaches used. The Handbook explores the distinctiveness of sustainable innovation and concludes with suggestions for generating future research avenues that exploit the current diversity of work while seeking increased systemic insight.
