Key info as displayed on https://lancaster-university.github.io/loco2026/: 2nd International Workshop on Low Carbon Computing (loco2026) 10-11 September, Lancaster, UK The carbon footprint of ICT is rising despite the urgent need to decarbonise society and to stay within planetary boundaries. The operational and embodied carbon emissions from ICT are already estimated to contribute between 2 to 3 percent of the global emissions and new technologies such as AI is driving overall growth in data centre demand, which globally rivals that of entire nations. This growth in emissions from computing is unsustainable and alternative low emissions pathways for computing are urgently needed. The LOCO workshop provides a forum for radical ideas, early work, and critical perspectives that aim to reduce the emissions from computing. See the website for deadlines!

Poster advertising the Disability Office Hours of the College of Science and Engineering at the University of Glasgow. UofG CoSE Disability Office Hours are an opportunity for students and staff with a disability to talk to a member of staff with a disability about anything disability-related. In other words, they are a chance to have a friendly and supportive conversation with a member of staff who has first-hand experience of the challenges that disabilities can pose. Our definition of disability is broad and includes all forms of long-term health conditions (including mental health), neurodiversity, and sensory and mobility impairments. We organise Disability Office Hours every semester, usually around UK Disability History Month (end of November) in Semester 1 and around Neurodiversity Celebration Week (end of March) in Semester 2. Specific dates and a list of colleagues involved can be found on the College website (with colleagues' personal information available in a Sway after logging in as a staff or student).
