Calculated based on energy-related emissions (power, heat, and fuel usage) and non-energy-related emissions (used for manufacturing processes, facilities) from sites.
GHG emissions from energy consumption (energy-related)
GHG emissions from energy consumption are calculated by multiplying the quantity of electrical power, heat and fuel (including fuel for motor vehicles, etc.) used at sites by the emission factors for each GHG. For energy consumption using renewable energy including certificates, the emission factors for each GHG are zero.
Emissions of PFCs and other greenhouse gases (non-energy-related)
Emissions of PFCs and other greenhouse gases are converted to CO2 emissions by multiplying greenhouse gas emissions from each site by its respective global warming potentials.
Global warming potentials are based on the Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC).
For mixed refrigerants not listed in the Sixth Assessment Report, the global warming potentials published by ASHRAE (American Society of Heating, Refrigeration and Air Conditioning Engineers) are applied.
GHG emission factors
- Electricity
Japan: Latest rate published at the end of each fiscal year by contracted power companies.
Outside Japan: Latest rate published at the end of each fiscal year by contracted power companies or that for the relevant country/region published by the International Energy Agency (IEA).
- Fuel & heat
Japan/Outside Japan: Calculation method and list of emission factors applicable to Japan's Act on Promotion of Global Warming Countermeasures are used (The Ministry of the Environment's Greenhouse Gas Emissions Accounting and Reporting Manual Ver. 6.1). The municipal gas and heat rate used in Japan for suppliers listed in the Ministry of the Environment's Greenhouse Gas Emissions Accounting and Reporting System is that listed for submission in fiscal year 2025. Otherwise, the alternative value indicated in the relevant list is used.
Sony's efforts to reduce greenhouse gas emissions through renewable energy use include using electrical power produced from renewable energy sources, purchasing electrical power produced from renewable energy sources, and purchasing renewable energy certificates and so on. Renewable electricity rates are calculated by the following equation.
Renewable electricity rate = renewable electricity consumption ÷ total consumption of sites × 100
Raw materials and parts for products
GHG emissions are aggregated for the resource extraction stage to the manufacturing stage for the raw materials and parts for products sold by the Sony Group in the Game & Network Services (G&NS) and Entertainment, Technology & Services (ET&S) segments, and for some products sold by the Imaging & Sensing Solutions (I&SS) and others. These are calculated by multiplying the gross weight of products sold in the fiscal year of reporting by an emission factor per the weight of products that was made within the Sony Group. GHG emissions for the manufacturing stage of display panels aggregate primary data from suppliers (Scope 1 or Scope 2) as GHG emissions.
Purchased goods
GHG emissions are calculated for office supplies purchased by the sites of the I&SS, ET&S segments and others, GHG emissions by multiplying the purchase amount of each item by an emissions intensity in the Emissions Unit Values for Accounting of Greenhouse Gas Emissions, etc., by Organizations Throughout the Supply Chain (Ver. 3.6), published by the Ministry of the Environment and the Ministry of Economy, Trade and Industry (Japan).
Contract manufacturing of products
Primary data (Scope 1 or Scope 2) from the major contract manufacturers of the products sold by the Sony Group in the G&NS and ET&S segments are aggregated as GHG emissions.
Data center and other information and communication services
For data center and other major information and communication services used by the Sony Group, GHG emissions include those obtained from vendors and are calculated by multiplying data traffic volumes and service usage fees by an emission factor created by the Sony Group or an emission factor published by external organizations.
GHG emissions are aggregated for the production of capital goods invested in by the Sony Group. These are calculated by multiplying the amount invested in facilities and software and the increase in right-of-use assets by an emissions intensity for household electronic appliances from the Emissions Unit Values for Accounting of Greenhouse Gas Emissions, etc., by Organizations Throughout the Supply Chain (Ver. 3.6), (6) Emissions intensity per unit price of capital goods, published by the Ministry of the Environment and the Ministry of Economy, Trade and Industry (Japan).
GHG emissions are aggregated for upstream from the procurement of fuel used by integrated ISO14001 certified Sony Group sites, and from the production process of electricity and heat. These are calculated based on the Emissions Unit Values for Accounting of Greenhouse Gas Emissions, etc., by Organizations Throughout the Supply Chain (Ver. 3.6), (7) Emissions Intensity from Electricity / Heat Usage, published by the Ministry of the Environment and the Ministry of Economy, Trade and Industry (Japan), as well as IDEA Ver. 3.5.1 emissions intensity.
GHG emissions are aggregated for those from international transport of Sony Group G&NS, ET&S, I&SS segments and other major electronics products (video game consoles, televisions, audio equipment, cameras, smartphones, image sensors, etc.), as well as regional transport of ET&S products in Japan, the US, Europe and Asia. For Japan, transportation for some G&NS and music products is included. These are calculated by multiplying ton-kilometers transported (weight of goods transported × distance traveled) by an emissions intensity. In certain instances, GHG emissions arising from transport by truck are calculated by multiplying an amount of fuel used (fuel consumption per kilometer × number of kilometers traveled) by an emissions intensity. For international transport by ship, the calculation uses the weight of goods transported including the weight of shipping containers. Emissions intensity (kg-CO2 / ton-kilometer) used for calculation uses the following values for international transportation.
| Ship | Aircraft | ||
|---|---|---|---|
| <463km | ≥463km & <1108km | 1108km≤ | |
| 0.01283 | 1.970224 | 1.483384 | 0.622734 |
Regional transport emissions are calculated by prioritizing the emissions intensity supplied by the applicable region or country. For Japanese domestic transport, Sony refers to the factor of the amount of fuel used per unit of freight transported (Ministry of Economy, Trade and Industry Notification No. 23 (2023)), based on the Act on Rationalizing Energy Use, and the emission factor related to fuel usage (Greenhouse Gas Emissions Calculation and Reporting Manual Ver. 6.1), based on the Act on Promotion of Global Warming Countermeasures. For transport in the United States, Sony uses the emissions intensity supplied by the SmartWay Transport Partnership, which is administered by the U.S. Environmental Protection Agency (EPA).
GHG emissions are aggregated for those related to the disposal and treatment of waste (excluding valuable waste) not generated at integrated ISO14001 certified Sony Group sites.
These are calculated by multiplying amount of waste processed and recycled by type at sites by the emission intensity from the Emissions Unit Values for Accounting of Greenhouse Gas Emissions, etc., by Organizations Throughout the Supply Chain (Ver. 3.6), (8) Emissions Intensity by Waste Type/Processing Method, published by the Ministry of the Environment and the Ministry of Economy, Trade and Industry (Japan), as well as IDEA Ver. 3.5.1 emissions intensity.
GHG emissions are aggregated for flights traveled by Sony Group employees on business trips in Japan, China, Europe, North America and South America, for which airline tickets are managed globally. These are calculated by multiplying the travel distance by the number of employees traveling, multiplied by an emissions intensity (kg-CO2 / person / km) for each class below.
| <463km | ≥463km & <1108km | 1108km≤ | |
|---|---|---|---|
| Economy | 0.129 | 0.079 | 0.077 |
| Premium Economy | 0.129 | 0.079 | 0.124 |
| Business | 0.129 | 0.119 | 0.225 |
| First | 0.129 | 0.119 | 0.310 |
GHG emissions are aggregated for the commutes of Sony Group employees. These are calculated by multiplying the number of employees in Japan, the United States, Europe, mainland China and Hong Kong, Asia-Pacific, and other regions and activity data calculated from the commuting methods specified for each region by an emissions intensity in [10] Emissions Unit Value per Passenger Kilometer or [11] Emissions Unit Value per Expenditures for Transportation Fares in the Emissions Unit Values for Accounting of Greenhouse Gas Emissions, etc., by Organizations Throughout the Supply Chain (Ver. 3.6), published by the Ministry of the Environment and the Ministry of Economy, Trade and Industry (Japan), or in IDEA Ver. 3.5.1.
GHG emissions are aggregated for the transportation of major products sold by the Sony Group's G&NS, ET&S segments and others from retailers to consumers. These are calculated by multiplying the assumed transportation ton-kilometer—the gross weight of products sold multiplied by the assumed transportation distance—by an emissions intensity for truck transportation in the Emissions Unit Values for Accounting of Greenhouse Gas Emissions, etc., by Organizations Throughout the Supply Chain (Ver. 3.6), published by the Ministry of the Environment and the Ministry of Economy, Trade and Industry (Japan).
GHG emissions are aggregated for the assumed processing of the major products of the I&SS segment sold by the Sony Group. This is calculated by multiplying the quantity of products sold in the fiscal year of reporting by an emission factor per quantity made within the Sony Group.
GHG emissions are aggregated for major Sony Group G&NS and ET&S electronics products. These are calculated by multiplying the assumed lifetime power consumption (including standby) of products sold in the fiscal year of reporting by an emissions intensity. (not the amount of GHG actually emitted during use of the fiscal year of reporting). In theory, GHG emissions during product use in the fiscal year of reporting should be calculated from the total quantity of electrical power consumed by previously sold Sony products that are still in use by consumers in the fiscal year of reporting. However, given the difficulty of determining how many previously sold Sony products are still in use by consumers of the total number of Sony products sold to date, Sony uses the estimated total quantity of electrical power consumed while in use over the lifetime of Sony products sold in the fiscal year of reporting to calculate GHG emissions during use. The hours of operation per year, standby time per year, and years of product use are calculated based on data obtained by various surveys. In Japan, Sony uses the latest emissions intensity provided by the Electric Power Council for a Low Carbon Society. Outside of Japan, it uses country or region-specific GHG emission factors as of the end of the applicable period provided by the International Energy Agency (IEA).
GHG emissions are aggregated for those associated with the recycling or disposal of major electronic products (video game consoles, televisions, audio equipment, cameras, smartphones, etc.) handled by the Sony Group's G&NS, ET&S segments and other disc businesses. These are calculated by multiplying the total amount for products sold for the fiscal year of reporting by an emissions intensity from the Emissions Unit Values for Accounting of Greenhouse Gas Emissions, etc., by Organizations Throughout the Supply Chain (Ver. 3.6), (8) Emissions Intensity by Waste Type / Processing Method, published by the Ministry of the Environment and the Ministry of Economy, Trade and Industry (Japan), as well as IDEA Ver. 3.5.1 emissions intensity.
GHG emissions are aggregated for some business activities of companies in which the Sony Group has invested. The Sony Group's equivalent GHG emissions are calculated by multiplying the GHG emissions of companies in which the Sony Group has invested by the Sony Group's ownership ratio of each company's shares. For companies that do not disclose their GHG emissions, this is calculated by multiplying the amount invested by an emission factor created by the Sony Group.
