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.

EU Horizone-Europe: Innovate for Sustainable Accelerating Systems (iSAS) 25m
With the ambition to maintain competitiveness of European accelerator-based research infrastructures and to enable Europe’s Green Deal, it has been proposed to Innovate for Sustainable Accelerating Systems (iSAS) [1]. iSAS aims to broaden, expedite and amplify the development and impact of novel energy-saving technologies to accelerate particles with enhanced collaborations. Presently, the iSAS consortium includes 17 partners from research institutions, universities and industry. For many frontier accelerators, superconducting RF (SRF) systems are the enabling technology. Facilitated by the extensive developments in preparing the European accelerator R&D roadmap, the synergies between the ERL and RF panels were exploited to innovate technologies which are common to SRF accelerating systems and have the largest leverage for energy savings in all phases of machine operation. Directly connected to the SRF accelerating system itself, three key technology areas requiring high power, can provide significant energy-savings: RF power, cryogenics and beam energy recovery. The objective of iSAS is to develop, prototype and validate new impactful energy-saving technologies so that SRF accelerators can provide the same, or improved, performance while using significantly less energy. Leveraging, and complementary to, current technological advances, the most promising and impactful technologies will be developed to increase their Technology Readiness Level and ease their integration into the largest existing European research infrastructures and/or in the design of future accelerator-driven research infrastructures by industry. iSAS considers three integration activities to introduce energy-saving technologies into research facilities: integration into the design of a new sustainable LINAC cryomodule, into existing cryomodules and into industrial solutions. While SRF systems with energy-recovery capability are an enabling technology for high-intensity beams with modern accelerators, the iSAS proposal emerges as a pathfinder for Europe to deliver the related energy-saving technologies more widely, including compact accelerators for a variety of applications. Importantly, the objective of iSAS is not only to raise the technology readiness to achieve impactful energy savings, but also to train experts and newcomers in the field.

The EU-Japan Regional & Cluster Cooperation Helpdesk: A bridge for promoting and accelerating industrial regional cooperation 25m
EU and Japan share key priorities for the future, especially in green transition and decarbonization. In Japan and Europe, local stakeholders – clusters, cities, regions, prefectures – are at the forefront of decarbonization, and future accelerators are involved in these initiatives for the green transition.
The EU-Japan Centre for Industrial Cooperation has put in place several years ago a dedicated Helpdesk to promote EU Japan cooperation at the local level of industrial clusters, regions and prefectures. https://www.ejrc-helpdesk.eu/
The EU-Japan Centre for Industrial Cooperation was established in 1987 as a joint venture of the European Commission (DG GROW) and the Japanese Government (METI) for promoting all forms of industrial, trade and investment cooperation between the EU and Japan. The centre is managing several other dedicated helpdesks as for instance the “EU-Japan Technology Transfer Helpdesk” as well as training programs (Vulcanus). The EU-Japan Centre for Industrial Cooperation Tokyo is the National Contact Point for Horizon Europe.Speaker: Virginie Fermaud (EU-Japan Regional & Cluster Cooperation Helpdesk)

High Efficiency Klystrons Projects at CERN 25m
All the future large scale accelerators projects for particle physics, like ILC, CLIC, FCC. CEPC and Muon Collider will consume enormous amount of RF power - at a level of 100MW of average power from grid. The base line option for all these projects is to use High Power (1MW-20MW) Low frequency (0.3GHz-1.3GHz) klystron amplifiers as RF power sources. Thus, the efficiency of these devices is one of the most critical elements of the overall accelerator power consumption. We will present the recent progress of the high efficiency (~85%) klystrons development at CERN.

Scenarios toward 2050 Carbon Neutrality in Japan and ILC 30m
Japan's scenario for achieving carbon neutrality is to reduce CO2 emissions and offset them by simultaneously increasing CO2 absorption. I will first explain the overall scenario, followed by the companies' presentations. The Tohoku region where the ILC will be located is blessed with forest resources and long coastal areas. Therefore, green carbon (CO2 absorption by forests) and blue carbon (CO2 absorption by seaweed) can be expected. We believe that the ILC, in cooperation with the community, should follow this scenario in its policies.

The Future of Construction: Carbon-Negative Concrete for a Greener Tomorrow 15m
Concrete, a construction material comprised of cement, water, sand, and aggregates, plays an indispensable role in the advancement of society. However, cement, the primary component of concrete, is the culprit behind CO2 emissions and an environmental challenge for the construction industry. To mitigate the environmental impact of concrete, it is essential to take a step back and meticulously reassess the composition of concrete. The construction industry is predominantly concentrating on three innovative strategies to assuage the carbon emissions associated with concrete. Firstly, substituting cement with industrial by-products, such as blast furnace slag powder and fly ash. Secondly, applying special admixtures that absorb CO2 in concrete products while performing carbonation curing to mineralise the CO2 in concrete. Lastly, employing waste materials containing mineralized CO2 as aggregates. Kajima is working on reducing environmental burden of construction and cultivating a sustainable society for the ensuing century.

PETRA IV and Sustainability 25m
DESY has a broad approach for sustainability and this ansatz is also being chosen for the upgrade of PETRA. In the PETRA IV project the focus is on energy efficiency. Optimisation of temperatures, waste heat usage and reduction of traveling are only some examples.
One of the highest energy consumers are the magnets. In order to save energy and space, the decision is made to use permanent magnets for bending of the beam. But of course there are also disadvantages. Permanent magnetic materials like NeFeB or Sm5Co17 have disastrous footprints. At the beginning of life cycle of permanent magnets, the mining and processing takes place under calamitous social and environmental conditions. The energy consumption during processing and production is enormous. At the end of life cycle there is as yet no industrial recycling chain and separation of the materials is a challenge. In context with PETRA IV and with support of IFAST, a workshop on rare earth elements was organised by the sustainability staff unit of DESY. We would like present our approach for sustainability in the PETRA IV project and the results of our workshop.Speaker: Dr Andrea Klumpp (D6 (Nachhaltigkeit)) -

A Life Cycle Assessment of the CLIC and ILC Linear Collider Feasibility Studies 25m
Linear colliders are a promising technology for exploring the frontiers of particle physics. However, the construction and operation of these large-scale scientific instruments have significant environmental impacts, particularly in terms of carbon emissions. In this talk, we present a comprehensive Life Cycle Assessment (LCA) of both the Compact Linear Collider (CLIC) and International Linear Collider (ILC) feasibility studies, focusing on LCA modules A1-A5 . A1-A5 modules include raw material extraction and manufacture, transport to works site and the construction process. The LCA evaluates 18 environmental impact categories, including carbon footprint, for CLIC and ILC. In addition, our study identifies opportunities for reducing the embodied carbon of linear colliders, through design optimisation and the use of low-carbon materials. We conclude that a careful consideration of the environmental impact of linear colliders is crucial for the future of particle physics research, and that reducing the embodied carbon of these large-scale scientific instruments should be a priority for the scientific community.

The HElmholtz LInear ACcelerator HELIAC – an advanced energy efficient and compact superconducting particle accelerator for heavy ions 25m
Nowadays, many fundamental scientific findings are obtained with the help of large-scale equipment. Particle accelerators for high-energy and high-intensity heavy-ion beams play a special role as key infrastructures for fundamental science, e.g. for the ambitious superheavy element program and for application-oriented research, including projects in material and life sciences. Innovative research with particle accelerators in fundamental physics requires ever higher particle energies and beam intensities. In the HELIAC project, we tackle the problem that increased particle energies and beam intensities are accompanied by a considerable increase in the demand for primary energy. Several developments towards efficient particle accelerators for a broad range of applications in fundamental, materials and life sciences have already been made. It is intended to investigate a novel and unique approach that combines a significant boost in energy efficiency, compactness and applicability for different user communities. The HELIAC-project targets the operation of sophisticated superconducting key elements in particular the so-called Crossbar H-mode (CH) radio frequency cavities, at 4 Kelvin and later on at 2 Kelvin, which promises an efficiency gain factor of up to 3. Compared to the currently operated GSI-UNILAC heavy ion accelerators, the cumulative efficiency gain would be in the order of a factor of 20 to 30. In the presentation, the novel heavy ion accelerator HELIAC will be introduced and, in particular, the significant energy saving potential compared to existing accelerator will be shown.

A Sustainability Roadmap for C3 25m
The particle physics community has agreed that an electron-positron collider is the next step for continued progress in this field, giving a unique opportunity for a detailed study of the Higgs boson. Several proposals are current under evaluation of the international community. Any large particle accelerator will be an energy consumer and so, today, we must be concerned about its impact on the environment. This paper evaluates the carbon impact of the construction and operations of one of these Higgs factory proposals, the Cool Copper Collider (C3). It introduces several strategies to lower the carbon impact of the accelerator. It proposes a metric to compare the carbon costs of Higgs factories, balancing physics reach, energy needs, and carbon footprint for both construction and operations, and compares the various Higgs factory proposals within this framework. For C3, the compact 8 km footprint and the possibility for cut-and-cover construction greatly reduce the dominant contribution from embodied carbon (see https://arxiv.org/abs/2307.04084)

A Sustainability Outlook for CLIC / ILC 40m
The CLIC project has pursued power reductions, energy efficiency and more general sustainability studies for almost a decade. These were initially motivated by the 3 TeV power projections but have since then allowed us to reduce the 380 GeV power by almost a factor two. The studies cover from design optimisation to technical developments of klystrons, RF systems and permanent magnets. Operation modes relying on renewable energy have been studies, and recently a life cycle assessment of the carbon footprint of the civil engineering was made. This talk will cover these studies, current status, and the planned future studies in 2024-25 to reach a full life cycle assessment of an optimised accelerator in two years time.
