Zippy's sustainability team gathers the assessment provided by respective departments in compliance with the GRI Standards. Through analyzing the stakeholder engagement standards and the company's status quo, we identify six major categories of stakeholders as employees, suppliers, customers, shareholders/investors, government authority, and local community. Our sustainable development committee gathers stakeholder’s concerned topics through multiple channels, lists 23 sustainable material topics as the guidelines for compiling sustainability reports, and then submits the "Communication with Stakeholders Report" to the Board of Directors every year.
