We would like to express our gratitude to Zeroboard Inc. for their support in our climate action initiatives and for providing us with their "Sustainability Assist" support.

Measuring GHG emission amount provides essential data for realizing a sustainable society and club. Measurement results allow us to understand where we are and verify, based on quantitative information, whether the actions we have taken are having the expected effect. With the support of Zeroboard, we will further promote climate action that will lead to the future of our region.
