Greenhouse Gas Emissions & Net Zero Commitment

Since 2012, when TWM adopted the ISO14064-1 standard, GHG inventories have undergone third-party verification annually to ensure data quality. The main source of emissions is electricity (98%); the remaining sources include use of company vehicles, generators, refrigerants, fire extinguishers and septic tanks.

Net Zero & GHG reduction targets

Taiwan Mobile has set a pioneering example in the Asian telecommunications sector by officially securing international validation through the Science-Based Targets initiative (SBTi). With a commitment to “limit global warming to 1.5°C”, Taiwan Mobile has established the important goal of achieving Net Zero emissions by 2050.

Furthermore, Taiwan Mobile completed target setting as early as 2019, Taiwan Mobile became the first telecommunications company in Taiwan to be certified for SBT WB2°C (well below 2°C) and pledged to achieve net-zero emissions by 2022. In August 2023, Taiwan Mobile continued to uphold international standards and further strengthened its own requirements, successfully passing the more rigorous SBTi 2050 Net-zero review.

Under the context of “limiting global warming to within 1.5°C”, Taiwan Mobile has established its short-term goals for 2030, which include a gradual phase-out of fossil fuel vehicles, improved energy efficiency, and active adoption of renewable energy sources. As a result, there has been a significant 42% decrease in greenhouse gas emissions for Scope 1 and 2 compared to the baseline year; 25% decrease in greenhouse gas emissions for Scope 3 compared to the baseline year.

Scope3	2050	2020	2030	25	2020	2050	90

By 2040, Taiwan Mobile aims to achieve a 90% reduction in carbon emissions. In the long term, if necessary, it plans to neutralize the remaining carbon emissions through methods such as carbon offsetting and carbon capture and storage, with the expectation of achieving net-zero carbon emissions by 2050.
