Supplementary material to "Hazard, risk, and adaptation disclosure pathways in UK Adaptation Reporting Power and EU annual reports"

Hereby we present preliminary supplementary material to the research titled "Hazard, risk, and adaptation disclosure pathways in UK Adaptation Reporting Power and EU annual reports". Preliminary summary of the research: Accounting research increasingly evaluates sustainability reporting through thelenses of information quality, comparability, and decision usefulness. Climateadaptation remains underexamined in the extant literature, particularly withrespect to whether reports link climate hazards, organisational risks, andmanagerial responses, within common report sections. The study addresses thisgap by developing a document section-level measure of hazard-risk-adaptation(HRA) disclosure pathways and applying it to all 300 historical instances of UKAdaptation Reporting Power (ARP) reports and annual reports of 150 EUexchange-listed firms spanning 2019-2024. Dictionary-based text analysisidentifies HRA content, classifies disclosures as numerical or narrative, and mapstheir co-occurrence within sections of the report. The results indicate two distinctpatterns. EU reports exhibit rapid growth in HRA disclosure over time,particularly in risk-related content. UK ARP reports, by contrast, displaysubstantially higher pathway integration, with far more sections linking HRAinformation. EU reports improve materially between 2021 and 2024, but HRAcommunication is more fragmented than in UK ARP reports. Numerical/narrativeform of disclosures does not emerge as a significant factor in HRA reporting. Thestudy contributes to accounting research by demonstrating that disclosurequantity and quality should not be treated as equivalent constructs. Furthermore,the study contributes to adaptation research by showing that adaptation reportingis most informative when hazards, organisational exposure, and responsemeasures are linked clearly, rather than mentioned separately, making adaptationmore assessable, comparable, and credible in corporate reporting.Keywords: climate adaptation disclosure; sustainability reporting; corporatereporting; information quality; text analysis; climate risk The research is currently submitted to be presented at the 29th Financial Reporting and Business Communication Annual Conference, University of Glasgow, July 2026.
