Research involving multistakeholder collaborative partnerships is growing, as both academia and funding agencies align their objectives with societal challenges and undertake research in the context of application. In particular, the UN sustainable development goals mandate green process innovation research that transcends disciplinary boundaries. Responding to this opportunity, this article explores the question: how can researchers, as societal stakeholders, collaborate in the design and implementation of a green process innovation research initiative and produce actionable research-based contributions to knowledge? Drawing upon our shared experience of realizing green process innovation, we describe and conceptualize the collaborative inquiry process, reflecting on the interplay of modes of knowledge production and the complementarity of researchers’ roles. We conclude by noting how researchers collaborating in a green process innovation initiative can shape the environment in which Transdisciplinary research (TDR) develops and play different roles enabling breadth and diversity of interaction, depth of disciplinary integration, and production of different types of knowledge.
