We promote the “paperless receipt service” comprehensively. As of 2023, the ratio of paperless receipts was over 73%. With 621 million sheets of paper saved, which is equivalent to 56,500 trees saved or 11,000 metric tons of carbon emissions reduced, we not only delivered protection of forest resources and biodiversity but also contributed to the global warming mitigation.

Supply Chain

As early as in 2008, we have been implementing “sustainable supply chain management action” as the first telecom operator that implemented the supply chain sustainability management. To strengthen the “sustainability level” throughout the supply chain, Chunghwa Telecom went first in the industry by securing two “Firsts in terms of Supply Chain”:

First ICT enterprise that launched the “sustainable supply chain” initiative, effectively connecting with authoritative sustainability organizations and partners around the globe to specifically respond to the UN SDGs together with our supplier partners.
First telecom operator in Taiwan that joined “CDP Supply Chain Program” to invite suppliers to fill out their carbon management information on the international platform, elevating the suppliers’ carbon management capabilities via the scientific, quantitative mechanism.

Procurement

Chunghwa Telecom proactively puts the idea of “green procurement” into action. It procures green products with green labels (low in pollution, recyclable, resource efficient, or green building materials), self-declared, or with lower environmental impacts throughout their lifecycles (from resource procurement to disposal) first and actively partakes in green procurement initiatives and campaigns in an attempt to encourage the green consumption trend in the industry and the broader society.

Aiming for an annual 5% of green procurement, we work to raise the green procurement to 50% or more in the overall procurement amount in the future. Also, ISO 20400 sustainable procurement guidance has been introduced to strengthen and exercise the green practices of sustainable procurement through the ISO procurement management system.

	2020	2021	2022	2023
Green procurement amount（NT$ million）	904	14,994	17,605	18,238
Percentage of green procurement amount（%）	1.08	22.37	28.67	29.39
