Formalising Sustainability Management as a Core Process Group in Project Management
Business Strategy and the Environment, EarlyView.ABSTRACT Sustainability has become a strategic imperative for organisations, yet widely used project management standards such as the PMBoK sixth and seventh editions still do not formalise how sustainability should be embedded across project work. This gap matters because PMBoK‐based processes shape governance, roles, documentation and performance ...

Limits of Provable Security for Homomorphic Encryption [PDF]
, 2013 We show that public-key bit encryption schemes which support weak (i.e., compact) homomorphic evaluation of any sufficiently “sensitive” collection of functions cannot be proved message indistinguishable beyond AM ∩ coAM via general (adaptive) reductions, and beyond statistical zero-knowledge via reductions of constant query complexity.

Business Strategy and the Environment, EarlyView.ABSTRACT This study examines the strategic efficacy of corporate low‐carbon energy transition, such as through nuclear energy adoption, as a response to decarbonization pressures. Analyzing an international sample of energy firms, we demonstrate that the relationship between this form of transition and emission reductions is not technologically ...

From Text to Value: Measuring and Pricing Firm Climate Risk Exposure
Business Strategy and the Environment, EarlyView.ABSTRACT We examine how the prominence and tone of climate risk disclosures affect firm value and strategic climate positioning for large European nonfinancial companies. We developed a firm‐level climate risk exposure (CRE) index that assesses climate risks within corporate narratives across four EU categories: transition risk, physical risk ...
