In 2024, the total operational greenhouse gas (GHG) emissions of Taiwan Semiconductor Manufacturing amounted to 14,500,793 metric tons of CO2 equivalent. This figure includes both direct emissions from owned or controlled sources (Scope 1) and indirect emissions from purchased energy (Scope 2).a
Compared to 2023, the total operational greenhouse gas (GHG) emissions of Taiwan Semiconductor Manufacturing increased by 11.01%, suggesting that the company faced challenges in reducing its emissions from its core operations.a
In 2024, the total Scope 1 emissions of Taiwan Semiconductor Manufacturing were 1,825,872 metric tons of CO₂ equivalent (tCO₂e).a
Compared to the previous year (2023), Taiwan Semiconductor Manufacturing's Scope 1 emissions increased by 14.4%, suggesting that the company faced challenges in reducing emissions from its directly owned or controlled operations.a
In 2024, Taiwan Semiconductor Manufacturing reported Scope 2 greenhouse gas (GHG) emissions of 10,957,397 tCO₂e using the market-based method and 12,674,921 tCO₂e using the location-based method.a
Compared to the previous year (2023), Taiwan Semiconductor Manufacturing's Scope 2 emissions (Location-Based) rose by 10.54% in 2024, suggesting that the company faced challenges in reducing emissions from purchased electricity and energya
In 2024, Taiwan Semiconductor Manufacturing reported its Scope 2 emissions using the market-based method and using the location-based method.a
In 2024, Taiwan Semiconductor Manufacturing reported 8,223,173 metric tons of CO₂ equivalent (tCO₂e) of Scope 3 greenhouse gas (GHG) emissions, representing indirect emissions across its upstream and downstream value chain.a
The 2024 disclosure of Taiwan Semiconductor Manufacturing includes a breakdown across 8 of the 15 Scope 3 categories defined by the GHG Protocol, matching the level of disclosure in 2023, demonstrating consistent Scope 3 emissions reporting coverage year over year.a
In 2024, Taiwan Semiconductor Manufacturing reported total Scope 3 emissions of 8,223,173 metric tons of CO₂ equivalent (tCO₂e).a
Approximately 99.96% of these emissions originated from upstream activities such as purchased goods and capital goods, while 0.04% came from downstream activities like product use, distribution, and end-of-life treatment.a
Since 2019, Taiwan Semiconductor Manufacturing's Scope 3 emissions have increased by 54.95%, reflecting a rising long-term trend in Scope 3 emissions over time.ab
Compared to the previous year (2023), Taiwan Semiconductor Manufacturing's Scope 3 emissions remained relatively stable, indicating that Taiwan Semiconductor Manufacturing's emissions have plateaued with no significant change in its value chain footprint.a
In 2024, Taiwan Semiconductor Manufacturing reported emissions for 8 out of the 15 Scope 3 categories defined by the GHG Protocol.a
This partial disclosure allows for some insight into the company's indirect impacts.
In 2024, the largest contributors to Taiwan Semiconductor Manufacturing's Scope 3 emissions were:a
In 2024, Taiwan Semiconductor Manufacturing reported Scope 1 greenhouse gas (GHG) emissions of 1,825,872 tCO₂e and total revenues of USD 88,349 millions. This translates into an emissions intensity of 20.67 tCO₂e per millions USD.a
In 2024, Taiwan Semiconductor Manufacturing reported a Scope 1 emissions intensity of 20.67 tCO₂e per millions USD. Compared to the peer group median of 3.33, this places the company above its industry benchmark, indicating it is less carbon-efficient than most competitors.a
In 2024, Taiwan Semiconductor Manufacturing ranked 18 out of 25 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
Taiwan Semiconductor Manufacturing is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
In 2024, Taiwan Semiconductor Manufacturing reported a total carbon footprint of 22,723,966 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 9.89% increase compared to 2023, suggesting a rise in emissions across its operations or value chain.a
The largest contributor to Taiwan Semiconductor Manufacturing's total carbon footprint was Scope 2 emissions, accounting for 55.78% of the company's total carbon footprint, followed by Scope 3 emissions at 36.19%.a
