Digitalisation and Carbon Efficiency: Does the Digital Economy Enable Sustainable Production Systems?

Business Strategy and the Environment, EarlyView.
ABSTRACT This paper examines the effect of digitalisation on carbon intensity in 44 countries from 2000 to 2024 using a principal component index that combines internet use, mobile connections and landline telephone ownership. The standard model uses a static Common Correlated Effects Mean Group (CCEMG) regression. Other specifications, such as CS‐ARDL(

A Meta‐Analytic Review of Board Characteristics and Carbon Emission Disclosure: The Moderating Effect of Contextual Factors

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT The relationship between board governance and corporate carbon emission disclosure remains persistently inconsistent across the empirical literature, despite decades of accumulated evidence. Drawing on agency, stakeholder, legitimacy, institutional, and upper echelons perspectives within a single analytical framework, we conduct a three‐level ...

An Excellent Deep‐Ultraviolet Nonlinear Optical Crystal Realized via a Functional Group Based on a Two‐in‐One Strategy

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A “two‐in‐one” design strategy integrating guanidinium and carboxyl functional groups was developed to overcome the intrinsic trade‐off among SHG response, ultraviolet cutoff edge, and birefringence in DUV NLO crystals. Benefiting from non‐π‐conjugated electronic isolation, Zn‐GPA(II) simultaneously achieves a strong SHG response (2.1 × KH2PO4), an ...
