Collaborating for Circularity: A Relational View Perspective on Buyer–Supplier Relationships in Restorative and Regenerative Supply Chains

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Industrial firms are required to redesign their supply chains into restorative and regenerative archetypes, rethinking not only their own production systems but also relationships with suppliers that may possess resources, capabilities, and knowledge too complex to be developed on their own but vital for circular value creation.

Civil Society Advocacy and Climate Change in Kenya: The Question of “Local Voices” and Their “Amplification”

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT The role of civil society organizations (CSOs) in addressing climate change is acknowledged, but engagement with questions of voice remains limited, especially in the Global South. Addressing this, this paper zooms in on (International) nongovernmental organizations ((I)NGOs) and their collaborations with domestic CSOs in the Global South on ...
