Direction ～Clean Energy～
Medium-term Management Plan•••

Building it into a business that will be main pillar.
We will work to create and improve our entire value chain. This includes
power generation equipment such as Gas Turbine that utilizes world-leadingammonia combustion technology, as well as our storage and receiving
terminals with top-tier performance.
While investigating investment in fuel manufacturing projects, we will utilize
our engineering capabilities to build a new business model.

This effort has yielded favorable environmental
outcomes.
✓ CO2 emissions at the unit have fallen around 20%.
✓ NOx emissions are almost equal before ammonia
substitution.
✓ SO2 emissions are down about 20%.
✓ Emissions of powerful greenhouse gas N2O havebeen undetectable.
