Launch of 'EVENT CARBON SIMULATOR': A Carbon Calculator Developed by the Event Industry
Dentsu Live and 15 member companies of the Japan Event Industry Association (JACE) have completed the core development of the 'EVENT CARBON SIMULATOR,' a new industry-standard tool for calculating carbon emissions. By utilizing a weight-based calculation method, the tool ensures objectivity and transparency, helping companies comply with upcoming Scope 3 disclosure requirements. The simulator is currently in trial operation, with plans for a future public release to promote sustainability across the industry.

This press release is issued by Dentsu Live on behalf of the operational working group consisting of 15 JACE member companies.
Dentsu Live Inc. (Headquarters: Minato-ku, Tokyo; President and CEO: Masato Nakamura), together with development partners from the Japan Event Industry Association (JACE; Headquarters: Chiyoda-ku, Tokyo; Chairman: Tadashi Ishii), has completed the core development of the 'EVENT CARBON SIMULATOR,' an industry-standard carbon calculator for event activity processes, which has been under development since June 2025. In conjunction with this, an 'Operational Working Group' consisting of 15 JACE member companies has been formed, and we are pleased to announce the commencement of trial operations aimed at a future public release.
Background: Responding to Sustainability Disclosure and Industry Challenges
Following the phased mandatory disclosure of information starting from the fiscal year ending March 2027 by the Sustainability Standards Board of Japan (SSBJ), the tracking and disclosure of corporate greenhouse gas (GHG) emissions have become unavoidable management issues. In particular, disclosure of the entire supply chain (Scope 3) is expected to become mandatory in the future, and the establishment of standards is being discussed in various quarters.
In the event industry, securing quantitative and objective evidence (calculation basis) that can withstand future disclosure requests is an urgent issue under these uncertain conditions. Against this backdrop, this calculator was designed with the highest priority on consistency and reproducibility of calculations, capturing the entire process from planning and production to the actual event and post-event phases, ensuring that 'anyone who measures will get the same result.'
Key Features of the EVENT CARBON SIMULATOR
- High-precision calculation based on 'weight'
Adopting a calculation method based on 'weight,' which reduces calculation errors, rather than the 'monetary-based' method often used in the past, which has large calculation errors. This enables the provision of more objective and transparent evidence.
- Establishment of industry-standard rules
Instead of individual company standards, we have built common industry calculation rules through JACE. This is based on the 'SUSTAINABLE ENGINE CARBON SIMULATOR' provided by Hakuhodo Product's Inc. in June 2024. This allows for comparative verification between events and the setting of reduction targets for the entire industry.
Future Roadmap
We have been conducting trial operations since April 2026, verifying usability and accuracy based on actual field data. We will continue our activities with the goal of making it available to the public in the future while reflecting these results.
Vision of the Operational Working Group
Through this calculator, we aim to realize a healthy competitive environment where event industry companies compete on the 'same playing field' to reduce environmental impact and improve design quality. By elevating sustainability efforts from individual company initiatives to an 'industry standard,' we will contribute to the cultivation of a sustainable event culture.
