Fiscal 2019 Scope 3 Emissions

*You can scroll horizontally

Scope category		Scope and method of calculation	Emissions (millions of t-CO₂e)
GHG emissions (Scope 1 + 2 + 3)		‐	22.84
Scope 1 (direct emissions)		‐	0.138
Scope 2 (indirect emissions from energy use)		‐	3.06
Scope 3 (indirect emissions from the value chain)			19.65
	Category 1: Purchased goods and services	Calculation based on the number of units and monetary value of purchases of devices and services sold to customers	4.08
	Category 2: Capital goods	Calculation based on capital investment costs on telecommunications and other equipment	6.02
	Category 3: Fuel- and energy-related activities not included in Scope 1 and 2	Calculation based on annual consumption by energy type	0.60
	Category 4: Upstream transportation and distribution	Calculation based on weight and distance, or number of devices with regard to the transport of devices sold to customers	0.05
	Category 5: Waste generated in operations	Calculation based on volume of waste by type	0.01
	Category 6: Business travel	Calculation based on paid expenses for business travel	0.19
	Category 7: Employee commuting	Calculation based on paid expenses for employee commuting	0.07
	Category 8: Upstream leased assets^*1	Excluded from calculation^*1	‐
	Category 9: Downstream transportation and distribution^*2	Excluded from calculation^*2	‐
	Category 10: Processing of sold products^*3	Excluded from calculation^*3	‐
	Category 11: Use of sold products	Calculation based on number of service subscriptions, number of devices and monetary value of telecommunications services and devices used by customers	5.67
	Category 12: End-of-life treatment of sold products	Calculation based on number of service subscriptions, number of devices and monetary value of communications devices used by customers	0.05
	Category 13: Downstream leased assets	Calculation based on average use of leased assets	0.75
	Category 14: Franchises	Calculation based on total floor area of sales franchises	0.09
	Category 15: Investments	Calculation based on Scope 1 and 2 emissions of investees in proportion to shareholding	2.07

We have excluded Category 8 (upstream leased assets) from the calculation because the fuel and electricity used by leased assets is included in Scope 1 and 2 calculations.
We have excluded Category 9 (downstream transportation and distribution) from the calculation because these emissions are almost entirely from our own transportation and use in our own facilities (included in Scope 1 and 2) or from outsourced transportation (included in Category 4).
We have excluded Category 10 (processing of sold products) from the calculation because our main businesses involve no processing of intermediate products.

GHG emissions

^*In fiscal 2013, the NTT Group became the first telecommunications carrier in Japan to calculate and disclose emissions from all 15 Scope 3 categories based on actual data for that year, in addition to the emissions generated directly from fuel use, etc. (Scope 1) and emissions generated indirectly in conjunction with electrical and other energy use, etc. (Scope 2). We based our calculations on the Ministry of the Environment's Basic Guidelines on Accounting for Greenhouse Gas Emissions Throughout the Supply Chain (Ver. 2.3). We will endeavor to improve the precision of our data collection while continuing to calculate and disclose Scope 3 emissions.

The CO₂ emissions from business operations exclude emissions of greenhouse gases other than CO₂.
The NTT Group provides equipment and the like necessary for other telecommunications carriers and data center providers to carry out their businesses. To date, we have included the fuel and electricity required for this equipment in our disclosed emission and consumption volumes in accordance with reporting methods outlined by the Act on Promotion of Global Warming Countermeasures. However, as calculation methods have been established based on the Ministry of the Environment's Basic Guidelines on Accounting for Greenhouse Gas Emissions Throughout the Supply Chain (ver. 2.3), we have adopted these for calculating the above CO₂ emissions as Scope 3. Emission amounts calculated using the previous method have been placed within parentheses. Similarly, for amounts of electricity purchased and total amount of non-renewable energy, from fiscal 2018 onward we are excluding the amount consumed by other telecommunications carriers and data center providers, and values calculated using the previous method will be placed within parentheses, and we have adopted these for calculating the above CO₂ emissions as Scope3 from fiscal 2019.
