Global media narratives refer to how international news outlets frame and present stories, shaping public perception and discourse on significant events like the COP15 UN Biodiversity Summit. This includes the themes, tones, and emphases used by different media sources to convey the importance, implications, and outcomes of such global events. This study explores global media coverage and narratives during the COP15 summit in December 2022, aiming to analyze dominant themes presented by international media, identify differences in reporting approaches among major outlets, and evaluate the influence of these narratives on public awareness and policy discourse regarding biodiversity. Using content analysis, the research studies news from various outlets to identify and quantify key themes such as ecological urgency, economic implications, policy negotiations, and scientific discoveries. Comparative analysis highlights variations in coverage focus, tone, and depth, revealing how regional contexts and media ownership influence reporting styles. Findings indicate that while some media outlets prioritize policy negotiations and economic implications, others emphasize ecological urgency and scientific findings, leading to varied public and policy responses. This research underscores the critical role of media in shaping public understanding and influencing policy debates on biodiversity. By providing insights into effective reporting practices, the study aims to enhance the quality of environmental journalism and foster informed public and policy engagement with biodiversity issues, contributing to the broader discourse on environmental communication and the power of media narratives in addressing global environmental challenges.
