Risks and opportunities


Inpex receives a trend score of -. If the company were reassessed in the near future, its score would likely decrease. Inpex ‘s scope 3 emissions are expected to exceed its 1.5°C carbon budget by 72% between 2019 and 2050 based on just its existing and approved fields. Despite this, the company continues exploring for new oil and gas. The company’s new business strategy is unlikely to be sufficient to align it with a 1.5°C pathway. It lacks a target covering scope 3 emissions as well as targets and deployment schedules to back its plans to scale up low-carbon business activities.
