Of the equity share emissions in 2023, we have obtained third-party verification for Scope 1 emissions 4,478 thousand tons and Scope 2 emissions 34 thousand tons from the production projects where INPEX takes the operator role as of December 31, 2023, and from INPEX headquarters and technical research center.

1

Scope 1: Direct emissions from resources owned or controlled by the reporting company. Categories 4 & 9 are being included in Scope 1 from 2021.

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 and renewable energy.

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.

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

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. Categories 4 & 9 are being included in Scope 1 from 2021.
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

For waste amount reporting from FY2023 onward, the aggregation classification has been changed to comply with GRI 306 reporting standards.

7

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.”

8

Among general waste, all waste is counted as landfill since the amount of waste classified as non-flammable is not known by treatment category.

9

From FY2023 onward, the amount of waste generated from excavation-related work such as cutting has been counted individually.

10

Historical data has been revised.
