Sustainable Development and Value Co‐Creation in International Business‐to‐Business Contexts: An Empirical Analysis in the Nonwoven Industry

Sustainable Development, EarlyView.
ABSTRACT Regulations and the collective influence of the value chain compel business‐to‐business (B2B) actors within the nonwoven (NW) manufacturing industry to drive sustainable development. However, the literature rarely addresses how B2B actors aim to align with sustainable development to co‐create value and what challenges they face.
