Hashimototen introduces EcoNiPass, a CO2 emissions visualization platform, to visualize CO2 emissions at construction sites

WingArc1st Inc. is pleased to announce that Hashimototen Co., Ltd. (Hashimototen), a general contractor based in Miyagi Prefecture, has introduced EcoNiPass, a CO2 emissions visualization platform, to promote visualization and reduction of CO2 emissions at its construction sites as part of its CSR activities. This reduces the burden on on-site employees, partner companies, and data collectors at the head office, and promotes environmental initiatives.

■Background　
Hashimototen is proactively involved in environmental conservation activities, and as part of these activities, has been working toward becoming carbon neutral, including reducing commuting time by car to reduce CO2 emissions. However, the work involved in collecting and compiling the data was extremely cumbersome, and there was a need to improve efficiency.

Hashimototen was looking for a system to collect data to understand the amount of CO2 emissions without imposing a workload on the site, and chose EcoNiPass.

The key reasons for introducing EcoNiPass are:
- Easy-to-understand system for calculating CO2 emissions: CO2 emissions are calculated based on the fuel consumption amount shown on receipts and invoices.
- Data can be easily collected by simply saving the PDF file to a shared folder on the cloud, and the type and amount of fuel can be identified.
- Data entry service reduces the burden of data collection work.
- No charge for viewing CO2 emissions data after construction is completed (a fee structure suited to the construction industry).

■Benefits
Hashimototen is now able to understand the amount of CO2 emissions at construction sites where approximately 40 pieces of heavy machinery of various types and sizes are used. The platform has established a foundation for collecting data and understanding emissions without imposing additional workload on staff either at headquarters or across approximately 400 partner companies.

- Hashimototen has considered specific measures to reduce emissions in Scope 1 and Scope 2, and laid the groundwork for partial realization of Scope 3 emissions.
- Awareness of carbon neutrality has increased, especially among young on-site managers.

The new system has already delivered insights into emissions trends. For example, Hasimototen identified that approximately 70% of the CO2 emissions are fuels used at construction sites, of which 55% is diesel fuel used by heavy machinery. Civil engineering sites, where large heavy machinery is used for foundation work, emit more CO2 than building construction sites.

It's also possible to understand other data points, such as the CO2 emissions from heaters required to prevent freezing before the concrete hardens during winter construction work. Hashimototen is seeking further improvements through data utilization.
