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 ...

Evaluation of Governance, Environmental, Socioeconomic, and Financial Dimensions Through an Integrated Multicriteria Decision‐Making Approach

Business Strategy and the Environment, EarlyView.
ABSTRACT Sustainable governance depends on the joint functioning of institutional quality, fiscal discipline, environmental performance, and socioeconomic inclusion. However, many composite indicators rely on subjective weighting schemes and leave the structural role of governance underspecified.
