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 ...
