Extent, characteristics and policy applications of Key Biodiversity Areas

Biological Reviews, EarlyView.
ABSTRACT A global standard for the identification of Key Biodiversity Areas (KBAs) was published 10 years ago to provide a unified set of criteria for identifying ‘sites of significance for the global persistence of biodiversity’. We review the initiative's origins, the KBA identification process, characteristics of the current network, threats, policy

Communication of Business‐Nonprofit Collaborations and Environmental Legitimacy: Exploratory Insights From Italian Firms

Business Strategy and the Environment, EarlyView.
ABSTRACT Collaborations with nonprofits can enhance firms' legitimacy, yet the relationship between their communication and corporate environmental legitimacy remains poorly understood. Furthermore, research lacks an analysis of the communication of business‐nonprofit collaborations through multiple actors' perspectives.

Corporate ESG Greenwashing: Does Regulatory Proximity Matter?

Business Strategy and the Environment, EarlyView.
ABSTRACT Environmental, social, and governance (ESG) greenwashing undermines sustainable development, yet the influence of regulatory proximity on oversight is understudied. By introducing the “distance decay effect” from geoeconomics into ESG misconduct research and using a sample of Chinese listed firms from 2009 to 2022, this study reveals a ...

Digital documentation of railway tunnel inspection in Austria

Civil Engineering Design, Volume 7, Issue 1, Page 3-8, March 2025.
Abstract Infrastructure, especially railway tunnels, require continuous inspection to ensure their safety. Furthermore, the detection of damages at an early stage can improve their service life. These tasks represent a major challenge for those involved and the tunnel down time is a disruption in operation.
