The concept of the Sustainable Development Goal (SDG) was first introduced in September 2015 at the United Nations Sustainable Development Summit, which consisted of 17 main areas that need to be explored to fulfil the 2030 Agenda for Sustainable Development. The global concept took its prominence in 2020 due to many organisations' rampant application of the model due to the COVID-19 pandemic. This global effect can also be seen in Malaysia, as publicly listed companies have been advised by Bursa Malaysia to shift their focus, make sustainability part of their business goals, and for the companies to report their sustainability efforts in their annual report as evidence supporting these global efforts. This effect can also be seen in the academic research direction, where most researchers include this concept in their framework in one way or another to measure the effectiveness of the SDG item in the business. However, it has come to the attention of the researchers that there are significant knowledge gaps when it comes to the communication aspect of the concept. Limited research addresses the most effective way to communicate business sustainability efforts, particularly from the perspective of communication content. This research addresses this issue by examining how companies employ storytelling elements to communicate their sustainability efforts to target audiences. Focusing on Malaysia's leading telecommunication companies, the study conducts a qualitative content analysis of selected sustainability advertisements disseminated through YouTube. All the extracted content will later be sub-grouped using the thematic analysis method to identify the storytelling techniques, brand archetypes and dimensions of sustainability storytelling technique used by the marketers. This study contributes to the comprehension of effective communication practices within the context of sustainable development goals (SDGs), providing valuable insights into the strategic use of storytelling and brand archetypes in sustainability advertising campaigns. Moreover, this study lays the groundwork for future research endeavours in communication, content writing, and storytelling, enriching the broader discourse on sustainability communication within academic and professional domains. This research initiates future sustainability communication research, particularly in communication, content writing and storytelling.
