In June 2024, colleagues from across the high-energy physics (HEP) community joined forces for the third Sustainable HEP workshop. There were over 230 registered attendees participating from all around the world via Zoom, and speakers on topics ranging from the gases used in particle detectors to energy-efficient cooling for large facilities. We also held a ‘Know Your Footprint’ session to help researchers investigate their own personal and professional carbon footprints. Part of this workshop was a joint session with the UK’s Particle Accelerators and Beams Group conference, held in Workington and hosted by the University of Manchester’s Dalton Cumbrian Facility.
