Besides asking suppliers to comply with domestic labor and environmental regulations on the basis of the procurement requirements, we called on the three main departments-the internet, the supply, and the administrative management- to complete the questionnaire “Survey on Chunghwa Telecom’s Supplier Corporate Social Responsibility” based on the “Electronics-Tool for Accountable Supply Chains” (E-TASC) developed by the Global e-Sustainability Initiative GeSI in 2009.
