Environmental Policy and Governance, EarlyView.ABSTRACT Since the 1990s, environmental policy has shifted toward ecosystem protection and biodiversity conservation, a development often described as an ecological turn. This article argues that in practice this turn has taken the form of an ecological “U‐turn,” as environmental ambitions are subordinated to production‐oriented objectives.

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.

Journal of Product Innovation Management, EarlyView.ABSTRACT Academic Summary Despite the urgent need for a circular economy, firms' transition from linear to circular business models (CBMs) remains slow. While previous research suggests that dynamic capabilities are the key drivers of this transition, it assumes a direct link, overlooking that these capabilities can facilitate change but do not ...

From quantity to quality: the evolution of forest restoration in the United Kingdom
Restoration Ecology, EarlyView.Abstract Introduction Over the past century, forest cover in the United Kingdom has increased threefold. However, the pathways, achievements, and shortcomings of this expansion remain underexplored. Objectives This study analyses the drivers, implementation, and legacies of forest restoration in the United Kingdom before and after 1990, which is when ...
