Collaboration beyond the supply network for green innovation: insight from 11 cases

Purpose This paper aims to explore the how, why, who and what of collaborations in green innovation. Design/methodology/approach The study is based on 11 case studies conducted at high-technological firms where 30 top management representatives were interviewed. Findings The study shows that firms share knowledge on green innovation across industries through horizontal collaborations and their extended network, such as their suppliers' and customer's networks in other industries. The results also show that digitalization, connectivity and big data are considered important vessels to improve environmental sustainability, as firms believe that these technologies will result in large gains related to resource utilization. Finally, the firms in this study engaged to a wide extent in green innovation activities, which resulted in a variety of improved resource utilization related to energy efficiency, new materials, new technologies, limiting emissions and recycle management. Originality/value The study contributes to the field of supply network collaboration by studying how firms collaborate to improve environmental sustainability.
