Worldwide Data Collection System
|
|
|
|
Sony uses the intranet-based data collection system to monitor and manage the progress of the environmental impact of all sites in the Sony Group. This system permits headquarters to collect data monthly from sites around the world.
Persons in charge at each site use the data collection system to input data concerning energy, water, waste, chemical substances and environmental costs, which is then checked by supervisors. Data administrators for the Japan, Americas, Europe, Pan Asia and East Asia regions also check the data. In order to ensure efficient collection and tabulation, in addition to the checks at several points, data checks are executed by the system at data input to reduce the possibility of errors. |

Scope, Collection Period, and Accuracy of Compiled Data
|
|
|
|
|
|
| Collection period: April 1, 2006 - March 31, 2007 |
|
| · | Data from some business sites includes estimates. | | · | Collection period for some figures of PFCs and other greenhouse gas emissions are from January 1, 2006 to December 31, 2006. |
|
|
|
|
|
|
|
|
| Scope of data collection |
|
Business site data: All ISO14001-certified sites as of March 31, 2006.
| · | Principally data is collected from non-manufacturing sites with 100 or more employees and manufacturing sites of consolidated Sony Group business sites and some joint venture companies in which Sony holds a capital stake of 50% for the ISO14001 certification. | | · | Data of some ISO14001-certified sites located outside of Japan is not included. Some ISO14001 non-certified sites voluntarily compiled and submitted were included.
Product data:
All products manufactured by the Sony Group and sold outside the Group are covered. Accessories, semi-manufactured products and components are included. Weight data covers the weight of the packaging materials. |

|
| Data accuracy |
|
Data for sites:
The chemical substance data and environmental cost data collected from certain sites may be slightly less accurate than other data.
Data for products:
Data for some semi-manufactured products, components, and some products produced and sold overseas may be slightly less accurate than other data. |

Greenhouse Gas Index Data Collection Methods and Rationale
|
|
|
|
The greenhouse gas index is calculated as follows.
The greenhouse gas index
(1) Total greenhouse gas emissions from sites (calculated in terms of CO2) + (2) Total CO2 emissions from product use + (3) Total CO2 emissions from logistics - (4) Greenhouse gas emissions offset by greenhouse gas reduction activities |
|
|
|
|
|
(1) Total greenhouse gas emissions from sites
< CO2 emissions by energy consumption > |
|
| CO2 emissions by energy consumption are calculated by multiplying the quantity of electrical power and fuel (including fuel for motor vehicles, etc.) used at sites by the CO2 conversion rate. |
|
|
|
|
|
|
|
| < PFCs and other greenhouse gases emissions > |
|
PFCs and other greenhouse gases emissions are converted to CO2 by multiplying greenhouse gas emissions from each site by global warming potentials.
The global warming potentials are based on the Third Evaluation Report of the Intergovernmental Panel on Climate Change (IPCC). |
|
|
|
|
|
|
|
| < CO2 Conversion Rates > |
|
Japan: The rates announced by the Federation of Electric Power Companies of Japan.
Overseas: The rates proposed by the GHG Protocol*
For CO2 conversion rates for electricity, the rates of each country in fiscal 2000 are used.
| * | Internationally accepted accounting and reporting standards for companies and other entities to report their greenhouse gas emissions, operated under the umbrella of the World Business Council for Sustainable Development (WBCSD) and the World Resource Institute (WRI). |
|
|
|
|
|
|
|
|
|
|
|
|
| (2) Total CO2 emissions from product use |
|
CO2 emissions from product use are calculated by multiplying the quantity of electrical power consumed throughout the lifetime of products sold in fiscal 2006 by the CO2 conversion rates. (It is not the actual quantity of CO2 emitted in FY2006.) The CO2 emissions from product use are calculated by the following equation.
Number of 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
The hours of operation per year, standby time per year, and years of product use are calculated based on data obtained by various surveys.
The same conversion rates as CO2 emissions from sites for each country in fiscal 2000 are used. But as for the data up to fiscal 2003 outside of Japan, the factors of the following countries are used according to the destination of the products.
North America: U.S.
Europe: Germany
Other regions: Singapore |
|
|
|
|
|
|
|
| (3) Total CO2 emissions from logistics |
|
CO2 emissions arising from procurement of parts, domestic shipment and international logistics handled by Sony Supply Chain Solutions Inc. are covered.
For domestic transportation by trucks, transportation volume is calculated by multiplying the transported weight by the transported distance. CO2 emissions are calculated by multiplying transportation volumes by the factor of "amount of fuel use per transported volume" defined in the "Law concerning the Rational Use of Energy" and "the emission factor of fuel type used" in "Law concerning the Promotion of the Measures to Cope with Global Warming".
For domestic transportation by rail, ship, and air freight, transportation volume is calculated by multiplying the transported weight by the transported distance. CO2 emissions are calculated by multiplying transportation volume by "the CO2 emission unit of transported tons multiplied by kilometer according to the type of transportation" defined in the "Guidelines for CO2 emission calculation method in logistics: Version 1.0" issued by Ministry of Economy, Trade and Industry and Ministry of Land, Infrastructure and Transportation.
For international transportation, transportation volume is calculated by multiplying the transported weight by the transported distance, and the CO2 conversion rate proposed by the GHG protocol is used. |

|
|
| (4) Greenhouse gas emissions offset by greenhouse gas reduction activities |
|
The quantity of electrical power from renewable energy, purchased quantity of electrical power generated by renewable energy and CO2 offset by contribution including Green Power Certificate System.
The quantity of electrical power from renewable energy and purchased quantity of electrical power generated by renewable energy have a CO2 conversion rate of zero.
CO2 offset by contribution including the Green Power Certificate System is calculated by multiplying the quantity purchased by the CO2 conversion rate, and deducting the result from the total CO2 emissions. |
