GHG Emissions

GHG Management System

Chunghwa Telecom was the first in the industry to conduct GHG inventory in 2008 with a 100% coverage of its branch offices.

With The Greenhouse Gas Protocol: A Corporate Accounting and Reporting Standard (GHG Protocol) developed by the World Resources Institute (WRI) and the World Business Council on Sustainable Development (WBCSD), we established the GHG emissions inventory and became the first domestic telecom operator that obtained the Verification Statement for ISO 14064-1 from the third-party entity, SGS Taiwan, which serve as the information basis for GHG reduction and carbon management promotion.

Greenhouse Gas (GHG) Emissions

The total greenhouse gas (GHG) emissions by CHT in 2021 is 734,866.729 t-CO2e, which include CO2、CH4、N2O、HFCs、PFCs and SF6. NF3 has been excluded since we did not emit any NF3.

The primary energy source for CHT operation is electricity. The GHG emissions mainly fall in the Scope 2 (purchased electricity), accounting for 97.57%, and in the Scope 1 from transport work vehicles, accounting for 2.43% only. There was a slight decrease in the total emissions in 2021 thanks to implementation of various energy efficiency and carbon reduction measures.

Direction Emissions (Scope 1)(t-CO₂e) 28,455.5921 22,192.9316 17,887.470
Indirection Emissions (Scope 2)(t-CO₂e) 795,295.4952 768,128.0670 716,979.259
Total Emissions (Scope 1 + Scope 2)(t-CO₂e) 823,751.0873 790,320.9986 734,866.729
Emission Intensity (t-CO₂e/NT$ million) 4.0 3.8 3.5

In 2021, in accordance with ISO 14064-1:2018 and with reference to the Corporate Value Chain (Scope 3) of the GHG Protocol, Chunghwa Telecom probed into the GHG emissions in its upstream and downstream business activities. We conducted inventory for categories 3, 4, and 5 and has obtained the verification statement from BSI Taiwan.

Reduction Target

Chunghwa Telecom joined the Taiwan Alliance for Net Zero Emission in 2021, proposing the target of net-zero emissions by 2030/2050. Also, it has announced its commitment to the science-based target (SBT), i.e. a 50% carbon reduction by 2030 compared to the base year levels of 2020. In addition, it planned to submit the SBT for review in 2 years.

Energy Saving and Carbon Reduction Plan and Results

To cope with the climate change risks and introduce more benefits from energy saving and carbon reduction, Chunghwa Telecom formulated tangible energy saving and carbon reduction action plans. In addition to active energy efficiency improvement, through autonomous environmental measures and practices, it compiles and analyzes energy data for a science-based management.
