Global climate change has shaken up our energy and economic systems. The fossil fuels, which helped us through the last century , starting with coal and followed by oil and gas have led to accumulation of 1500 billion tons of CO2 in the atmosphere and disturbed the earth's ecosystem balance significantly. It includes hydro cycle, temperature rise, oceans warming and hence ocean currents,...
We live in a climate emergency and consequently all countries are putting in place measures to reduce their carbon emissions in order to reach a so-called “net zero emissions” by 2050. All aspects of economic life will be affected by such measures, including particle physics research. I will present some examples of sources of carbon emissions within the field of particle physics. This will...
From genetic studies and astrophysics simulations to AI, scientific computing has enabled amazing discoveries and there is no doubt it will continue to do so.

mate tipping points less likely, we call for resource-aware knowledge
gain in the research areas on Universe and Matter with emphasis on
the digital transformation. A portfolio of measures is described in de-
tail and then summarized according to the timescales required for their
implementation. The measures will both...
Global warming is one of the biggest challenges of mankind due to non-linear, self-enhancing (exponential) dependencies of the climate on human-made factors. The production of concrete for the construction industry is responsible for 5-8% of the global carbon footprint. A solution could be extending the lifetime of buildings and civil infrastructure. A key requirement for this is the ability...
In the Belle II collaboration, a discussion of the sustainability topic began in 2023. A survey showed that many Belle II members care about the topic. We will report about the status of a grassroots initiative to address the sustainability challenge of research at Belle II.
A recent survey within the particle astrophysics community suggests that reducing the number of meetings and conferences is a viable way to address concerns about the effectiveness of the modern scientific collaboration process, its effects on the environment and the well-being of researchers. The results of the survey were published in a Comment in Nature Astronomy. In this presentation we...
Saturated fluorocarbons (SFCs: CnF(2n+2) ) are chosen for their optical properties as Cherenkov radiators, with C4F10 and CF4 used at CERN in the COMPASS and LHCb RICH detectors. Non-conductivity, non-flammability and radiation resistance also make SFCs ideal coolants: C6F14 liquid cooling is used in all LHC experiments, while C3F8 is used for the evaporative cooling of TOTEM and the ATLAS...
Scientists are becoming more aware of the impact of their activities on the environment. They also want to base their analysis of the situation on measurements, leading to decisions to minimise their contribution to climate change and pollution. With this in mind, scientists in French labs started the Labos 1point5 initiative in 2019, to collect what is already being done, study how research...
Resistive Plate Chamber (RPC) are gaseous detectors widely employed in High Energy Physics experiments. Thanks to their comparatively low cost and excellent timing and positioning performance, they are used to cover large detection areas, such as those needed by the muon trigger systems of the LHC experiments (RPCs are currently employed in ALICE, ATLAS and CMS and they are also being...
Renewable energy sources are widely recognized for their ability to provide affordable, reliable energy with reduced environmental impact. The South Pole is the site of the both current and future HEP experiments and presents singular conditions for a transition to renewables. South Pole power is currently supplied by diesel generators and the associated complex and costly transport of...
Gaseous detectors are indispensable as they serve a multitude of diverse applications in particle and nuclear physics, but also in industry, e.g., in the national security domain. To stay at the forefront of rapidly changing particle detector technologies for future detector applications, gaseous detectors must face a critical global challenge: sustainability. Today’s RPC detectors utilise...
Future accelerators must be assessed for sustainability during their life cycle, including construction, operation, and decommissioning, to meet the global goal of carbon neutrality by 2050. Accelerator scientists should strive to achieve performance with less electric power in the optical design phase of accelerators, and to improve power efficiency during the design and manufacture of...
Whereas Energy and Energy Transitions are typically approached from a Technological Science and Physics perspective, it is increasingly acknowledged that these topics have a very strong Social Science component as well. For instance, in many cases developments in energy and energy transitions have consequences for people and society, and people's perceptions of these developments have a...

The largest power demands of most future colliders, particularly Higgs factories and muon colliders, is dominated by the wall-plug-power required to run the RF systems and its cooling. Most of this power does not end up in the beam but is power lost as heat in the RF amplifiers, cavities and RF loads. This power lost is not a fundamental limit and there has been recent progress in addressing...
The Circular Electron-Positron Collider (CEPC) aims to construct a top-performing Higgs factory to tackle pressing issues in particle physics.
