1. The figure for crude oil production is an estimate based on the “Life Cycle Inventory (LCI) Compilation for Petroleum Products by Type and Environmental Impact Assessment of Petroleum Products” (March 2000), issued by the Japan Petroleum Energy Center (JPEC).

2. The figure for crude oil and raw material transport is calculated using the amount of bunker fuel consumption during ocean transport, the calorific value of grade C heavy fuel oil, and the CO2 emission coefficient specified in the Greenhouse Gas Emission Calculation and Reporting Manual of Japan’s Ministry of the Environment and Ministry of Economy, Trade and Industry.

3. The energy consumption figures for manufacturing, product transport and storage (oil depots), service station sales, research centers, and offices were calculated in accordance with the provisions of the Act on the Rational Use of Energy (Energy Saving Act).

4. CO2 emissions from manufacturing, product transport and storage (oil depots), service station sales, research centers, and offices were calculated in accordance with the Greenhouse Gas Emission Calculation and Reporting Manual of Japan’s Ministry of the Environment and Ministry of Economy, Trade and Industry. Based on the GHG Protocol, energy usage includes energy usage to produce electricity and steam sold externally.

5. Data for the petroleum business in the “manufacturing” stage covers the three refineries of Cosmo Oil Co., Ltd. and the Yokkaichi Kasumi Power Plant, as well as Cosmo Oil Lubricants Co., Ltd. Data for the petrochemicals business covers Cosmo Matsuyama Oil Co., Ltd. and Maruzen Petrochemical Co., Ltd.

6. Electricity sold covers the electricity supplied externally by the Chiba Refinery of Cosmo Oil Co., Ltd., and the Yokkaichi Kasumi Power Plant, as well as the Chiba Plant of Maruzen Petrochemical Co., Ltd.

7. Steam sold refers to steam supplied externally by the Chiba Refinery of Cosmo Oil Co., Ltd., Cosmo Matsuyama Oil Co., Ltd., and the Chiba Plant of Maruzen Petrochemical Co., Ltd.

8. Data on CO2 emissions from product transport is based on “specified shippers” as stipulated by Japan’s Energy Saving Act.

9. CO2 emissions from consumption (product use) is calculated by multiplying the shipment volume of products used as fuel, such as gasoline and heavy fuel oil, by the CO2 emission factor. In addition, CO2 emissions associated with electricity and steam sold are totaled separately.

10. Data for research centers covers the Research & Development Center of Cosmo Oil Co., Ltd., the Product Research Center of Cosmo Oil Lubricants Co., Ltd., and the research centers of Maruzen Petrochemical Co., Ltd.

11. Data for offices covers total electricity usage for offices of Group companies implementing Eco Office activities (Cosmo Energy Holdings, Cosmo Oil, Cosmo Oil Marketing, and Cosmo Energy Exploration & Production), as well as Maruzen Petrochemical Co., Ltd.

12. Data for product storage covers the Sakaide and Hakodate distribution terminals of Cosmo Oil Co., Ltd.
