This workshop is designed to help university students understand and practically apply the international standard ISO 14064-1: Organizational-Level Greenhouse Gas (GHG) Inventories. As climate change becomes an increasingly urgent global issue, countries are implementing carbon reduction policies, and organizations are facing mounting pressure to disclose emissions, comply with carbon pricing mechanisms, and commit to net-zero goals. For students, gaining knowledge in carbon management and sustainability has become a key competitive advantage in the job market. The course begins with an overview of climate change and ESG (Environmental, Social, and Governance) trends, followed by a structured introduction to the ISO 14064-1 standard. Key topics include defining organizational and operational boundaries, categorizing GHG emissions (Scopes 1, 2, and 3), collecting activity data, and applying emission calculation principles. Through real-life case studies and hands-on exercises, students will learn how to build an emissions inventory, select appropriate emission factors, and draft a preliminary GHG inventory report. The course will also cover the basics of third-party verification and data quality management. With simulation-based inventory exercises and group discussions, participants will gain practical insights into how carbon accounting supports corporate sustainability management. This workshop lays a strong foundation for students interested in future roles related to carbon governance, ESG projects, or sustainability careers. It is suitable for students from diverse academic backgrounds including environmental studies, sustainability, business, engineering, and design—no prior experience is required.
