Metrics, Targets, and Results

Targets

The INPEX Group has defined fatalities, serious injuries, and major leaks as major incidents that must never occur during its operations. We set "Zero Major Incidents" as one of our management targets, and it is a common safety target covering all employees. The scope for our targets regarding fatalities and serious injuries includes employees and contractors.

Results

In FY2025, there were two major incidents: a fatality at a construction site in Japan, and an incident resulting in a serious injury at a drilling site in Japan. The victims in both incidents were contractors.

Metrics Targets FY2025 Results Unit
Fatalities 0 1 persons
Serious injuries 0 1 persons
Major leaks (PSE Tier 1)1 0 0 cases
  • 1
    In line with IOGP requirements, unexpected releases or leakages of substances, including flammable liquids, are classified in tiers depending on the degree of consequence (personal harm, direct cost to the Company, type and quantity of material released, etc.). PSE Tier 1 refers to those with the most significant consequences.

Other Metrics and Targets

Based on the HSE Policy, we have established quantitative and qualitative HSE targets, studied their priorities, and formulated action plans for the continuous improvement of HSE performance. To quantitatively measure our safety performance, we monitor two safety metrics of incidents resulting in injury for all employees and contractors involved in our projects: the lost time injury rate (LTIR)*1 and the total recordable injury rate (TRIR)*2. We gather such data in accordance with reporting guidelines defined by IOGP. For LTIR, we also monitor our progress toward the targets we have set for employees and contractors while benchmarking ourselves against IOGP participating companies.

Our LTIR for FY2025 was 0.33, representing a year-over-year improvement and achieving our target for the year (0.41).

  • *1
    Rate of fatalities and injuries resulting in lost time per million hours worked
  • *2
    Rate of fatalities, injuries resulting in lost time, and injuries not resulting in lost time or requiring medical treatment per million hours worked

HSE-related Targets and Results

The evaluation of HSE-related initiatives in FY2025 and actions are detailed below. Please refer to Biodiversity Conservation and Environmental Pollution Measures for details on our initiatives related to the environment.

Targets Evaluation Incidents/Actions
Strengthening of initiatives for Group-wide incident reduction to achieve zero major incidents Poor
  • INPEX Group-wide LTIR and TRIR improved from last year (2024: LTIR 0.45, TRIR 2.06; 2025: LTIR 0.33, TRIR 1.93).
  • Two major incidents (a fatality and a serious injury) occurred.
  • Given the occurrence of major incidents, corporate-level incident investigations were conducted to thoroughly investigate the factors behind the incidents, and measures to prevent the recurrence of incidents, including ensuring proper schedules, thorough risk management, and Group-wide safety education, were formulated.
Enhancement of Group-wide process safety management Good
  • Toward operation of mechanisms for ensuring Group-wide process safety management competency, awareness-raising activities were conducted for the persons in charge of operational organizations to recognize the importance of demonstrating leadership. Preparations toward trial implementation of these mechanisms and establishment of education and training materials were also advanced at each organization.
  • Requirements and such in the quarterly process for HSE risk management and reporting were reviewed and risk visualization was improved.
Establishment and implementation of HSE management in all business areas Good
  • HSE management in businesses not related to oil or natural gas, including Kashiwazaki Hydrogen Park, Nagaoka Methanation Demonstration, and Okuhida geothermal well drilling projects was continued. For Kashiwazaki Hydrogen Park and Nagaoka Methanation Demonstration, start-up reviews during plant completion and process safety confirmation toward commencement of operations were conducted.
  • HSEMS documents are being updated to achieve more efficient and effective HSE management according to business characteristics.
Enhancement of HSE communication by senior management Good
  • Five site visits by senior management to sites in Japan were conducted, conveying the message of safety first and discussing HSE management of sites.
  • The scope of informal meetings and inspections during site visits is being expanded within our organizations in Japan.
  • An HSE meeting was held in October with the participation of senior management, including the Representative Director, President & CEO, to discuss various measures for preventing the recurrence of major incidents.
