By using reduced-cement concrete, we were able to greatly lower CO₂ emissions during the construction of Dommy Minami-Nagasaki Annex, a residential building. As a result, we were awarded J-Credits for the project.* On a side note, we also used a new blockchain-based platform we completed in March 2022 that allowed us to visualize the volume of CO₂ emitted during construction. The platform made it much easier for us to determine our overall CO₂ emissions in the project and also facilitated our J-Credit application process.
