Low carbon and sustainable computing
The Low Carbon and Sustainable Computing (LOCOS) Theme groups the research in the School related to the sustainability of computing. The main focus is on reduction of emissions from computing. However, research in computing science can help in many other ways with reducing of greenhouse gas emissions and mitigation of the effects of climate change.
By 2040 emissions from computing alone will more than to half the emissions level acceptable to keep global warming below 1.5°C. This growth in computing emissions is unsustainable. The emissions from production of computing devices far exceed the emissions from operating them, so even if devices are more energy efficient producing more of them will make the emissions problem worse. Therefore we must extend the useful life of our computing devices.
The vision for Low Carbon and Sustainable Computing Theme is simple but ambitious:
- Imagine we can extend the useful life of our devices and even increase their capabilities without any increase in energy consumption, purely through advances in Computing Science: better algorithms, better software design, better programming languages and compilers etc.
- Meanwhile, we will develop the science and technologies for the next generation of devices, designed for energy efficiency as well as long life through pervasive hardware-software co-design.
- Every subsequent cycle will last longer, leading to computing resources that last virtually forever and use very little energy.

LC&SC Seminar: Envirofy: A Techno-Fix for Sustainable Online Grocery Shopping (05 May, 2022)
Speaker: Dr Gözel Shakeri
Two thirds of global greenhouse gas (GHG) emissions of Western countries are attributable to consumption and commerce, however a behavioural shift could reduce this by 49%. Many people intend to make sustainable choices, but fail to do so at the point-of-purchase. Educating consumers on the environmental impact of their choices during their shop may be a powerful approach to tackling climate change. In this talk I will present Envirofy, an eco-friendly e-commerce grocery tool for real shoppers. I will share how we use the Behaviour Change Wheel (BCW) and multidisciplinary evidence to maximise the likely effectiveness of Envirofy. I will discuss how the Human-Computer Interaction community can help to develop and evaluate real-time tools to close intention-behaviour gaps and ultimately reduce GHG emissions. Finally, I conclude with a short opinion piece on Envirofy's role (a techno-fix) in the politicised debate around climate change.
Dr Gözel Shakeri is a post-doctoral research associate in Human-Computer Interaction at the Carl Ossietzky University, Oldenburg. Her research interests focus on Sustainable Human-Computer Interaction (HCI), using behaviour change intervention science to create interfaces that support online shoppers in purchasing sustainable products
LC&SC Seminar: Salt Water Computing (28 April, 2022)
Speaker: Devine Lu Linvega
LC&SC Seminar: The Climate Impacts of ICT (21 April, 2022)
Speaker: Dr Kelly Widdicks
The Climate Impacts of ICT
Information Communication Technology (ICT, including devices, networks and data centres) has environmental impacts associated with each stage of its lifecycle, with current studies estimating that the world’s ICT forms 1.8-2.8% of global greenhouse gas emissions. However, this share is likely underestimated as the full supply chain impacts of ICT are not considered, meaning ICT’s true share of global greenhouse gas emissions actually forms between 2.1-3.9%. Current studies’ estimates vary even further for the future environmental impact of ICT as experts take varying underlying assumptions that are not always made explicit. In this talk, Dr Kelly Widdicks will discuss the research she conducted with colleagues at Lancaster University and Small World Consulting (published in Patterns) on the climate impact of ICT. Specifically, she will reveal why current estimates vary and detail the underlying assumptions that impact estimates of ICT’s future environmental impacts. She will also discuss the threats that will likely increase ICT’s environmental impacts and the efforts required to align the ICT sector with global carbon targets.
Dr Kelly Widdicks is a Lecturer in Computer Science in the School of Computing and Communications at Lancaster University, researching the sustainable and responsible design of digital technology. She utilises quantitative and qualitative methods in the field of Human-Computer Interaction to explore how people’s use or innovation of digital technology affects its environmental impacts. She is currently a co-investigator for the EPSRC PARIS-DE project, exploring design principles for the responsible innovation of digital technology in line with Paris Agreement targets. Alongside this, she also researches how Computer Science as a discipline could be made more inclusive for women and underrepresented groups.
