In order to reduce the amount of paper used and improve administrative efficiency, UMC implemented an electronic operating system, continued to digitize the receipt and delivery of electronic documents, electronic forms, and price comparison lists, and saved 31,623 sheets of paper in 2021.
In the office part, we adopted a multi-functional office machine (certification number: ring mark No. 13859) that has obtained the Energy Conservation and Environmental Protection Mark of the Energy Bureau of the Ministry of Economic Affairs, and made good use of the function of the transaction machine, and reduced the use of paper through the following measures.

1. Standby energy saving is enabled after work, and external faxes are received electronically instead of printed directly
2. Advocate double-sided printing or multi-page printing in a single sheet, and encourage employees to make good use of recycled paper blank sides for reuse
3. Documents are not actively printed and other management mechanisms to avoid repeated waste caused by misprinting
4. Order return is also electronically sent back by digital signature as much as possible
5. Internal documents between the company and the factory or related enterprises, unified aggregation and transmission, and reuse of briefcases
6. Transportation by means of transportation to reduce the use of new envelopes and reduce the waste of resources caused by repeated delivery of the same address
7. The photocopy paper is made of PEFC environmental certification 100% renewable agroforestry pulp
8. The inner pages of the business diaries printed during the reporting year were printed with soy ink and environmentally certified paper, making a contribution to environmental protection
