The International Workshop on  

Sustainability in Future Accelerators

September 25 - 27, 2023, Morioka, Japan



In the construction, operation, and post-experimentation phases of global large-scale accelerator projects, it is essential to minimize environmental impact and strive towards realizing a sustainable society. Therefore, the focus of this workshop is to elucidate the current status and future challenges of these endeavors, particularly within the globally anticipated linear collider project.

The environmental credential of future colliders are increasingly in the spotlight, because of their size and complexity, and will be under scrutiny for their impact on the climate. Therefore, sustainability is becoming a prioritized goal in the design, construction and post-experimental phases of future large-scale accelerator facilities. Approaches to improved sustainability range from overall system design, optimization of subsystems and key components, to operational concepts. A direct quantification of the ecological footprint, be it greenhouse gas emissions during construction and operation, or consumption of problematic materials, is currently performed only sporadically, mostly through translation of electricity consumption into equivalent CO2 emissions, with Lifecycle Assessments (LCA) emerging as a more comprehensive approach. Such assessments provide the accelerator community with new guiding principles for sustainable large-scale future projects. Two large-scale electron-positron linear colliders are currently being studied as potential future Higgs-factories, ILC in Japan and CLIC at CERN. These are the central elements of the recently approved EAJADE (“Europe-America-Japan Accelerator Development and Exchange") Marie Sklodowska-Curie staff exchange action under Horizon-Europe that will run for four years, starting in 2023. The focus of this workshop is to elucidate the current status and future challenges for sustainability of large-scale accelerator infrastructures, with particular focus on the globally anticipated linear collider project.

The geothermal power plant located on the eastern foothills of Hachimantai began full-scale operations in January 2019. Its output is 7,499 kilowatts (kW), making it the first geothermal power plant in Japan to exceed 7,000 kW in 22 years. The plant generates electricity using geothermal energy extracted through two production wells. After powering the turbines, the plant recycles the residual heated water, supplying it to the city of Hachimantai. (LOC translation of Japaense Wikipedia)
