Independent Assurance Report

To ensure the reliability of environmental and social performance data included in Sustainability Report 2022, INPEX has obtained independent third-party assurance from SOCOTEC Certification Japan for all data marked with the symbol () in the ESG Performance Data section.

Scope of Assurance: 2022 data covering the period from January to December for the following environmental and social performance data.

Environmental performance

<Scope: Operational control* in Japan>

• Scope 1 emissions (by emission source, gas type)
• Scope 2 emissions
• Energy consumption
• Water consumption and discharge of produced water
• Emissions to the atmosphere (VOC, NOx, and SOx)
• Waste – hazardous waste (recycling, final disposal) and non-hazardous waste (recycling, final disposal)
• Oil Spill (quantity of spills)

<Scope: Overseas operational control**>

• Scope 1 emissions (emission source, gas type)
• Scope 2 emissions

<Scope: Equity share based***>

• Scope 1 emissions
• Scope 2 emissions
• Scope 3 Category 11 emissions (use of sold products)

Social performance

<Scope: Operational control* including Japan and global organizations>

• Lost time injury rate (LTIR) by contract
• Total recordable injury rate (TRIR) by contract

* HSE and GHG emissions management data are reported on an operational control basis and include operational organizations in Japan, INPEX headquarters, and the INPEX Technical Research Center.

** The production projects where INPEX takes the role of operator as of the end of December 2022, and overseas offices are included.

*** Equity share-based Scope 1 and Scope 2 emissions cover the production projects where INPEX takes the role of operator as of the end of December 2022, INPEX headquarters and the INPEX Technical Research Center. Scope 3 Category 11 emissions are calculated by multiplying the total sales volume of crude oil, natural gas, and LPG by each product’s emission factor, under the assumption that the total volume of each is combusted.
