Quantity of power, heat, and fuel usage and quantity of greenhouse gases used for manufacturing process, within facility and others are collected.
CO2 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 CO2 conversion rate.
Emissions of PFCs and other greenhouse gases are converted to CO2 by multiplying greenhouse gas emissions from each site by global warming potentials. Global warming potentials are based on the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC).

CO2 emissions from product use are calculated by multiplying the quantity of electrical power consumed throughout the lifetime of products sold in the current fiscal year by the CO2 conversion rates. (In other words, it is not the actual quantity of CO2 emitted in the current fiscal year.) CO2 emissions from product use are calculated by the following equation.
Sales x (Operating power consumption x Hours of operation per year + Power consumption during standby time x Standby time per year) x Years of product use x CO2 conversion rate
In theory, emissions during product use in the current fiscal year 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 current fiscal year. 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 total quantity of electrical power consumed while in use over the lifetime of Sony products sold in the current fiscal year for CO2 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 2014 CO2 conversion rate provided by the Federation of Electric Power Companies of Japan. Outside of Japan, it uses the 2013 country-specific CO2 conversion rates provided by the International Energy Agency (IEA).
Total CO2 emissions from logistics include emissions arising from international logistics and logistics within over 40 countries and regions such as Japan, the United States, Europe, and Asia associated with Sony Group's electronics products. For logistics within Japan, CO2 emissions from parts logistics are partially included.
CO2 emissions from logistics are primarily calculated by multiplying ton-kilometers transported (weight of goods transported x distance traveled) by the CO2 conversion rate. In certain instances, CO2 emissions arising from transport by truck are calculated by multiplying the amount of fuel used (fuel consumption per kilometer x number of kilometers traveled) by the CO2 conversion rate. For international transport by ship, the calculation uses the weight of goods transported including the weight of shipping containers.
For international transport, the CO2 conversion rate used to calculate CO2 emissions is based on the emissions intensity supplied by the GHG Protocol. For regional transport, priority is given to using the rate supplied by the region or country. For Japanese domestic transport by truck, CO2 emissions calculations multiply the weight of freight transported by two factors: the amount of fuel used per unit of freight transported, as defined in the Law concerning the Rational Use of Energy, and the emissions factor of fuel type used, as defined by the Law concerning the Promotion of Measures to Cope with Global Warming. For transport in the United States, Sony uses the emissions rate supplied by the SmartWay Transport Partnership, which is administered by the U.S. Environmental Protection Agency (EPA).
Emissions are calculated for business trips undertaken by employees in central departments, which account for the largest share of business trips taken by employees of Sony Corporation and Sony Group Electronics Business companies in Japan, Europe and North America and for business trips taken by employees from some electronics-related companies in Asia and the Middle East. (In the case of Japan and North America, some music-related companies are included.)
CO2 emissions are calculated by multiplying the distance traveled by the number of employees traveling using the basic unit of output proposed by the GHG Protocol.
Sony’s efforts to reduce greenhouse gas emissions by using renewable energy include using electrical power produced from renewable energy sources, purchasing electrical power produced from renewable energy sources, and purchasing green energy certificates and other carbon offset credits. The greenhouse gas emissions reduction achieved by using renewable energy is calculated by multiplying the renewable energy used by the CO2 conversion rate.
