Environmental Pollution Measures

Response to Blowouts and Oil Spill Incident

INPEX needs to be prepared not only for large-scale blowouts and oil spills at oil and natural gas development sites, but also for small-scale spills from tanks and pipelines at production facilities, which may affect the local community’s safety, health, and business interests.

We have developed rules and procedures for consistent management aimed at preventing incidents. We also work with oil spill response organizations, including Oil Spill Response Limited – the world’s largest provider of oil spill response services – to develop response structures according to our projects’ risks and establish a structure for responding to a large-scale oil spill. At the same time, we constantly acquire knowledge of oil spill response technologies.

Other Efforts for Environmental Pollution Measures

Prevention of Air Pollution

To reduce the impact of its business activities on air quality, we monitor our emissions and air quality and take measures to prevent air pollution in line with the laws and regulations of countries in which we operate our projects, and international good practice.

Air pollutants emitted from our project sites include sulfur oxides (SOx), nitrous oxides (NOx), and volatile organic compounds (VOCs). In our operator projects, we manage emissions by identifying the sources of Air pollutants – such as production processes, fuel combustion facilities, venting of natural gas, and shipment by tank trucks – and measuring and managing the amount of emissions released, striving to reduce air pollution.

Values may fluctuate because the amount of Air pollutants emitted is significantly affected by factors such as the state of operation of each facility. In FY2024, SOx emissions within the INPEX Group totaled 653 tons. NOx emissions stood at 3,380 tons, which is almost the same level as FY2023. Non-methane VOC (NMVOC) emissions were 3,023 tons, up approximately 14% from FY2023.
