- Figures are estimated on the actual production volumes of petroleum products in Fiscal 2005.
- Figures for crude oil production, crude oil transportation, and product transportation are estimated based on LCI for Petroleum Products by fuel and Environmental Impact Assessment for Petroleum Products, published in March 2000 by the Petroleum Energy Center.
- Figures for refining and product consumption are derived from Environmental accounting. See website of the Related Data for the methods and basis of calculations.
Energy consumption is calculated according to the Energy Saving Law.
- Refining include data from the Yokkaichi Kasumi Power Station and Cosmo Matsuyama Oil Co., Ltd.
- Electric power sold refers to power sold by Chiba Oil Refinery, Yokkaichi Kasumi Power Station, and Cosmo Matsuyama Oil Co., Ltd. The CO2 emission from refining is the amount after deduction of CO2 emissions, a result of such power generation. It is includes CO2 emissions for the purchased electricity.
- Figures here do not include CO2 emissions associated with the construction of facilities.
- SOx emission from the use of products is informational. It is estimated from the potential sulfur content of products without taking sulfur reduction during use into consideration. Accordingly, actual SOx emission is lower than the estimate.
- In addition to CO2 emission from the use of products, the emission from the sold power is estimated separately.
- Naphtha used mainly as petrochemical material emits neither CO2 nor SOx in normal state, but CO2 and SOx emissions from the use of products are estimated assuming naphtha emits both.
