Risks and Opportunities


Inpex receives a trend score of -. If the company were reassessed in the near future, its score would likely decrease. The company’s scope 1, 2 and 3 emissions intensity has decreased between 2019 and 2021, though not at the pace required by its 1.5°C pathway. Its targets are reliant on an unquantified use of offsets. Inpex has also not set any scope 3 emissions targets, which undermines the credibility of its transition plan. Moreover, the company continues exploration for new oil and gas fields, even though it is projected to exceed its scope 3 carbon budget by around 60% between 2022 and 2050.
