A Strategic Governance Perspective on Carbon Accounting Enablers: An In‐Depth Qualitative Examination of Business Strategies

Business Strategy and the Environment, EarlyView.
ABSTRACT This study advances a governance perspective on how firms implement, adopt, and routinize carbon accounting. Although prior research has identified several carbon accounting drivers and enablers, less is known about how these elements interact at the firm level to support the organizational embedding of carbon accounting.

Stakeholder Alignment Around Technological Pathways in Early‐Stage Sustainability Transitions: A Study of Stakeholder‐Perceived Stakes in Aviation Decarbonization

Business Strategy and the Environment, EarlyView.
ABSTRACT This paper examines how stakeholder groups become aligned or remain misaligned around alternative technological pathways during early‐stage sustainability transitions. We develop the concept of stakeholder‐perceived stakes, capturing how stakeholder groups evaluate technological pathways through perceived drivers and holdbacks, and how these ...

Circular Ecosystem‐Orchestrating Leadership: Microfoundations of Ecosystem‐Related Dynamic Capabilities for a Circular Economy Transition

Business Strategy and the Environment, EarlyView.
ABSTRACT The transition to a circular economy (CE) increasingly depends on circular ecosystems: networks of autonomous yet interdependent actors that must coordinate material, information, and value flows to narrow, slow, and close resource loops. This creates a governance problem: Circularity requires orchestration, yet no single actor can impose ...

Graded Solvation‐Structure Electrolyte for Synergistic Polysulfide Confinement and Interfacial Stabilization in Potassium‐Sulfur Batteries

Carbon Energy, EarlyView.
A graded solvation structure is designed through a strongly–moderately–weakly solvating strategy to synergistically regulate potassium polysulfide dissolution and K‐anode deposition behavior. This tailored electrolyte effectively stabilizes the electrode/electrolyte interphases and accelerates sulfur redox kinetics.

Durable Fuel Cell Cathode Enabled by Pt Embedded Nanoscale Carbon Network via a Scalable Process

Carbon Energy, EarlyView.
Platinum nanoparticles embedded nanoscale carbon network (Pt‐e‐Cn) are developed via a scalable flame spray pyrolysis process. Proton exchange membrane fuel cells (PEMFC) employing mesoporous Pt‐e‐Cn cathode electrocatalysts exhibit exceptional durability without compromising performance.
