Asuene Becomes First Environmental Partner of Hibiya Music Festival 2026, Estimates Total CO2 Emissions at 436.32 Tons

Asuene Inc. announced that, as the first environmental partner of Hibiya Music Festival 2026, it conducted a preliminary CO2 emissions assessment for the festival scheduled for May 30 and 31, 2026. The assessment estimated total event emissions at 436.32 t-CO2. Based on the globally recognized GHG Protocol, the calculation covered Scope 1 to Scope 3 emissions, including not only direct emissions by the organizer but also travel and consumption behavior by attendees and people involved in operations. The initiative is positioned as an advanced example among outdoor music events in Japan. Asuene and Hibiya Music Festival will use the findings to understand the event’s overall CO2 emissions and emissions structure, while pursuing initiatives that reduce environmental impact without compromising the attendee music experience. Using information from Hibiya Music Festival 2025, which drew 145,000 attendees, Asuene estimated the expected emissions for Hibiya Music Festival 2026. Major sources include attendee travel at 154 t-CO2, or 35.3%; venue setup at 170 t-CO2, or 39.1%; merchandise and food and beverage at 91 t-CO2, or 21.0%; waste at 11 t-CO2, or 2.4%; energy use at 7 t-CO2, or 1.6%; and organizer travel at 2 t-CO2, or 0.5%. Attendee travel was calculated using weighted averages based on an attendee profile survey conducted through the official Hibiya Music Festival 2025 app. While attendee travel is generally said to account for about 80% of total emissions at destination-type music festivals, it accounted for about 35% at Hibiya Music Festival, indicating a different emissions structure. This is attributed to the festival being free of charge and held in the open urban setting of Hibiya Park and surrounding areas in central Tokyo, attracting many nearby residents and people who stop by as part of their daily routines. The assessment also found that CO2 emissions per attendee were 3 kg-CO2, roughly one-third of the global music festival average of 11 kg-CO2. Asuene said this likely reflects the large share of nearby attendees, cooperation from staff, stakeholders, and participants who support the festival’s concept of being free and borderless, and the use of parks and existing facilities with minimal necessary temporary construction. Based on the insights gained, Asuene will examine concrete emission reduction measures for event operations and communicate approaches to environmental action in cultural events. The company noted that the assessment is an estimate based on available data and does not cover all emissions. It plans to continue verifying and improving the calculation method to enhance accuracy and expand such initiatives more broadly.
