In 2024, the total operational greenhouse gas (GHG) emissions of NTT amounted to 3,790,000 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 NTT decreased by 5.01%, showing that the company has made progress in taking action to reduce the climate impact of its operations.a
In 2024, the total Scope 1 emissions of NTT were 130,000 metric tons of CO₂ equivalent (tCO₂e).a
Compared to the previous year (2023), NTT's Scope 1 emissions decreased by 13.33%, highlighting the company's efforts to lower direct emissions from assets it owns or controls.a
In 2024, NTT reported Scope 2 greenhouse gas (GHG) emissions of 1,990,000 tCO₂e using the market-based method and 3,660,000 tCO₂e using the location-based method.a
Compared to the previous year (2023), NTT's Scope 2 emissions (Location-Based) have remained relatively stable, indicating that NTT's emissions have plateaued with no significant change in its energy consumption footprint.a
In 2024, NTT reported its Scope 2 emissions using the market-based method and using the location-based method.a
In 2024, NTT reported 14,410,000 metric tons of CO₂ equivalent (tCO₂e) of Scope 3 greenhouse gas (GHG) emissions, representing indirect emissions across its upstream and downstream value chain.b
The 2024 disclosure of NTT includes a breakdown across 12 of the 15 Scope 3 categories defined by the GHG Protocol, up from 0 in 2023, reflecting improved emissions accounting practices and greater transparency across the company's value chainb
In 2024, NTT reported total Scope 3 emissions of 14,410,000 metric tons of CO₂ equivalent (tCO₂e).b
Approximately 70.5% of these emissions originated from upstream activities such as purchased goods and capital goods, while 29.5% came from downstream activities like product use, distribution, and end-of-life treatment.b
Since 2020, NTT's Scope 3 emissions have decreased by 35.18%, reflecting a declining long-term trend in Scope 3 emissions over time.bc
Compared to the previous year (2023), NTT's Scope 3 emissions decreased by 23.47%, highlighting the company's efforts to lower indirect emissions from its value chain.ab
In 2024, NTT reported emissions for 12 out of the 15 Scope 3 categories defined by the GHG Protocol.b
This reflects a high level of granularity and transparency in the company's emissions reporting.
In 2024, the largest contributors to NTT's Scope 3 emissions were:b
In 2024, NTT reported Scope 1 greenhouse gas (GHG) emissions of 130,000 tCO₂e and total revenues of USD 88,315 millions. This translates into an emissions intensity of 1.47 tCO₂e per millions USD.a
In 2024, NTT reported a Scope 1 emissions intensity of 1.47 tCO₂e per millions USD. Compared to the peer group median of 1.97, this places the company below its industry benchmark, indicating it is more carbon-efficient than most competitors.a
In 2024, NTT ranked 11 out of 25 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
NTT is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
In 2024, NTT reported a total carbon footprint of 18,200,000 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 20.25% decrease compared to 2023, indicating progress in reducing its overall greenhouse gas output.ab
The largest contributor to NTT's total carbon footprint was Scope 3 emissions, accounting for 79.18% of the company's total carbon footprint, followed by Scope 2 emissions at 20.11%.ab
