Transforming CO2 Emission Management in Construction

In a significant stride towards sustainable construction, RIVASTA Corporation has introduced its CO2 calculation service, TansoMiru, which has notably reduced the CO2 emission aggregation workload by approximately 90% for Ando Hazama Corporation. This landmark achievement was made possible through the implementation of all four services offered by TansoMiru, targeting improvements in speed and efficiency in CO2 emissions data management on construction sites.

Background of TansoMiru Implementation

The decision to adopt TansoMiru stems from Ando Hazama's commitment to sustainability. The company has accelerated its sustainability initiatives in recent years, guided by its long-term vision, 'Ando Hazama VISION 2030,' established in February 2020. Among its key themes is the creation of environmental value, which led to the company's acquisition of 'SBT' certification in December 2019, as well as joining the RE100 initiative aimed at sourcing 100% renewable energy for its operations.

Despite these forward-thinking initiatives, the manual processes involved in calculating and aggregating CO2 emissions at various construction sites were cumbersome and time-consuming. Previously, data collection relied on spreadsheets, which delayed the availability of critical information and posed challenges in responding to sustainability-related financial disclosures.

In Japan, there are ongoing efforts to establish a system where listed companies gradually face mandates to disclose sustainability information alongside their financial statements, thus amplifying the need for a more efficient data aggregation framework. The introduction of TansoMiru was, therefore, a strategic move to enhance operational efficiency in this regard.

TansoMiru and Its Impact

Ando Hazama's journey with TansoMiru began in 2023, with a phased incorporation of services, including TansoMiru Management, TansoMiru Electric, TansoMiru Fuel, and TansoMiru Waste. This implementation enabled real-time data sharing across different levels of the organization, eliminating the need for cumbersome data transfer and aggregation.

The TansoMiru Electric service makes use of data received from electric companies to automatically compute CO2 emissions, greatly reducing input and verification burdens at the project sites. Consequently, the annual workload for collecting carbon emission data has been slashed by about 90%. Improvements in data accuracy are also noticeable, as machinery operational data can now be recorded with hourly precision instead of daily entries.

Future Prospects

Looking ahead, Ando Hazama plans to further expand the deployment of TansoMiru across more construction sites to enhance CO2 emissions management capabilities. Shinji Maeno, the Head of the ESG Strategy Group at Ando Hazama's Strategic Management Division, emphasizes that increased adoption of TansoMiru will allow for better oversight of the company's overall CO2 emissions trends. With ongoing developments in the automatic collection of fuel usage data via TansoMiru Fuel, Maeno anticipates further improvements in efficiency and convenience.

Moreover, Keiko Hiratsuka, the Director of the Quality and Environment Division at Ando Hazama, recognizes the importance of TansoMiru in facilitating data accumulation necessary for everyday operational tasks on-site. Their collaborative efforts with RIVASTA in creating presentation materials and responding to inquiries have been instrumental in supporting the transition to these optimizations.

Conclusion

TansoMiru is a revolutionary cloud service tailored for the construction industry, enabling precise CO2 emissions calculation and visualization. Composed of four distinct services, TansoMiru fosters transparency in CO2 emissions across the entire supply chain, contributing significantly towards decarbonizing management practices in the construction sector. RIVASTA continues to pave the way for innovative solutions to pressing challenges in the industry, aiming for a sustainable future. For more information, visit the TansoMiru service site.
