Business Strategy and the Environment, EarlyView.ABSTRACT Global imperatives, such as climate change, environmental concerns, and carbon emissions, make green transformation an inevitability in the logistics sector. Green logistics strategy formulation is an economic choice problem, but it also turns out to be a multicriteria decision‐making (MCDM) process that encompasses the triple bottom line (TBL)

Carbon Markets and Green Innovation: Path‐Dependent Firm Responses to Emissions Trading
Business Strategy and the Environment, EarlyView.ABSTRACT This paper identifies a dynamic boundary condition of the Porter hypothesis by examining how firms' pre‐existing innovation trajectories shape regulatory‐induced green innovation within the context of a market‐based carbon policy. Building on path dependency theory, we argue that firms' responses to environmental regulation are contingent on ...

Business Strategy and the Environment, EarlyView.ABSTRACT We examine whether incentive‐based policies reduce CO2$$ C{O}_2 $$ emissions among beneficiary Italian firms, using project‐level data from European cohesion policy. Exploiting quasi‐random variation in the timing of EU‐funded projects, we apply a staggered difference‐in‐differences design.

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.
