GHG Management System

In 2008, Chunghwa Telecom took a leading role in the industry by conducting a greenhouse gas (GHG) inventory covering 100% of our operational sites. We used the Greenhouse Gas Protocol developed by the World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD) as the inventory tool to establish a GHG emissions inventory. We obtained a verification statement from a third-party verifier (SGS-Taiwan), becoming the first telecommunications company in Taiwan to obtain ISO 14064-1 verification.

Greenhouse Gas (GHG) Emissions

The total greenhouse gas (GHG) emissions by CHT in 2023 is 2,479,027.7962 t-CO₂e, which include CO₂、CH₄、N₂O、HFCs、PFCs、SF₆、NF₃. We did not emit PFCs, SF₆, and NF₃; therefore, the values thereof are 0.

The primary energy source for CHT operation is electricity. The GHG emissions mainly fall in the Scope 2 (purchased electricity), accounting for 97.15%
The Scope 1 accounting for 2.85% only. There was a slight decrease in the total emissions in 2023, dropped by 15.94% compared with 2020 levels, thanks to implementation of various energy efficiency and carbon reduction measures.
Scope 3 (Categories 3-6): 1,814,662.2596 t-CO₂e; total GHG emissions of Scope 1, 2, and 3 (Categories 1-6): 2,479,027.7962 t-CO₂e

Notes：
1. An emission target of 710,000 metric tons, along with the challenge target of 675,000 metric tons, was set for 2023.
2. The Scope 2 emissions in the table above are calculated using a market-based approach.

Note: The data coverage is 100% of the group-wide operations and group-wide revenues.

Scope 3 Emissions

In 2023, In line with ISO 14064-1:2018 and with reference to the GHG Protocol Corporate Value Chain (Scope 3), Chunghwa Telecom investigated the 15 GHG emissions from the related business activities in the upstream and downstream to inventory the Scope 3, 4, and 5, and the verification statement was obtained from TÜV SÜD Taiwan.
