Particle physics is entering an era where the environmental impact of large-scale facilities must be evaluated, alongside their cost and physics output. In this talk, we explore the carbon footprint of proposed future collider projects, focusing on strategies to mitigate emissions without compromising physics goals. Using recent studies as a case study, we outline a methodology to quantify and...

This work explores the interdisciplinary concept of sufficiency leading us to reimagining economic theory through the lens of physics, with a particular focus on sufficiency corridors. Drawing inspiration from thermodynamics and systems theory, it proposes a shift away from traditional scarcity-driven models toward a paradigm grounded in balance and Earth system constraints. Sufficiency...

This work studies the interaction of cosmic rays, extraterrestrial particles with energies ranging from 10⁶ eV to 10²⁰ eV, which produce secondary particles, including neutrons, when they collide with atmospheric molecules. These neutrons can be used to non-invasively estimate soil moisture through cosmic ray neutron sensors (CRNS), opening the possibility of using this technology in precision...

The construction of detectors for the Large Hadron Collider (LHC) have substantial resource demands. As a case study, we examine LHCb Upgrade II, a major replacement of the LHCb detector planned for the 2030s. LHCb estimated Scope I and II carbon emissions for its Framework Technical Design Report, a first of its kind study. A brief overview of these results is given.

The pursuit of particle physics, or any kind of discovery-driven research, requires a stable and prosperous society. Today, our society is increasingly threatened by global climate change. Human-influenced climate change has already impacted weather patterns, and global warming will only increase unless deep reductions in emissions of CO2 and other greenhouse gases are achieved. Current and...

The cathode strip chambers (CSCs) of the CMS experiment are a type of multi-wire proportional chamber that operates with a mixture of Ar, CO$_2$, and CF$_4$ gases. CF$_4$ is a well known component preventing aging of the anode wires. It has, however, a high global warming potential (GWP), and reducing our reliance on it is critical for improving the ecological sustainability of the experiment....

The construction of an electron–positron collider 'Higgs factory' has been stalled for a decade, not because of feasibility but because of the cost of radio-frequency (RF) acceleration. Plasma-wakefield acceleration promises to alleviate this problem due to its orders-of-magnitude higher accelerating gradients, which result in a significant cost reduction based on a sizeable reduction in...
