Of the equity share emissions in 2022, we have obtained third-party verification for Scope 1 emissions 4,287 thousand tons and Scope 2 emissions 48 thousand tons from the production projects where INPEX takes the operator role as of December 31, 2022, and from INPEX headquarters and technical research center.

**

Items for which data are not collected are marked with n/c (not collected).

1

Scope 1: Direct emissions from resources owned or controlled by the reporting company
Scope 2: Indirect emissions from the consumption of electricity, steam, heat and cooling purchased by the reporting company
Scope 3: All indirect emissions that occur in the value chain of the reporting company

2

The emissions are calculated in accordance with local laws and regulations and rules for HSE-related data.

3

Net carbon intensity includes offset. The basic unit described here shows the GHG emissions of heat production rate per consolidated production of oil and natural gas.

4

The total amount of emissions corresponds to the net economic share of each production project.

5

Category 1: Total volume of contractor emissions and upstream emissions from the production of purchased goods. Category 11: The emissions are calculated by multiplying the total sales volume of crude oil, natural gas and LPG by CO2/CH4/N2O emission factor under the assumption that all amounts of crude oil, natural gas and LPG are combusted. The emissions are calculated from 2006 IPCC Guidelines for National Greenhouse Gas Inventories emissions factors.

6

HSE data are reported on an operational control basis including Head office, Technical Research Center, overseas offices and Operational Organizations in Japan and overseas.

7

From 2021, this data is included in Scope 1.

HSE data are reported on an operational control basis including Head office, Technical Research Center, overseas offices and Operational Organizations in Japan and overseas. "2 Scope 1: Direct emissions from resources owned or controlled by the reporting company Scope 2: Indirect emissions from the consumption of electricity, steam, heat and cooling purchased by the reporting company Scope 3: All indirect emissions that occur in the value chain of the reporting company"

3

The emissions are calculated in accordance with local laws and regulations and rules for HSE-related data.

4

The data is calculated in accordance with the laws and regulations of each country (including the Act on the Rational Use of Energy [Energy Conservation Act] in Japan).

5

Domestic: VOC emissions are calculated using the “PRTR Release and Transfer Calculation Manual for Oil Refineries and Oil Storage Depots, etc.” published by the Petroleum Association of Japan. Overseas: The emissions are calculated in accordance with the laws and regulations of each country.

6

The definition of hazardous wastes are in accordance with the laws of each country. Within Japan, “specially controlled industrial wastes” as stipulated in the Act on Waste Disposal and Public Cleansing are set as “hazardous wastes” and other wastes (including “industrial wastes” and “municipal waste”) are set as “non-hazardous wastes.”

7

Since general waste discharge volume by disposal category is uncertain, the entire discharge volume of general waste has been included in the final disposal amount.
