From Hydrocarbons to Green Investment: Longitudinal Topic Modeling and Sentiment Analysis of Sustainability Framing in Omani Newspapers (2015–2025)

The news media in Gulf countries are among the most important institutions shaping the public’s understanding of climate action. This study aims to explore the longitudinal developments, thematic framing, and sentiment tones of Omani English-language newspapers’ sustainability discourse during the period 2015–2025. The study applied a multi-stage computational method to analyze a deduplicated corpus of 709 news articles from two English-language dailies of Oman: Times of Oman and Oman Daily Observer for a time period from 2015 to 2025. Latent Dirichlet Allocation (LDA) topic modeling was used to group topics into five types of macro frames. Results show that the focus of the Omani media is very localized, and the dominant frames are “Corporate ESG, Business & Green Investment” and “Clean Energy Policy, Research & Institutional Governance”. Furthermore, a sentiment analysis of headlines using VADER showed clearly defined sentiment polarity; domestic economic transition headlines were characterized by high positive polarity, while global climate crisis headlines had a higher negative polarity. The study concludes that the press in Oman is in a strategic process of “nationalizing” the climate change issue, moving from the conventional disaster discourse to making sustainability a local opportunity for economic diversification, technological modernization, and national resilience.
