The growth of semiconductor technology is unprecedented, with profound transformational consequences for society. This includes feeding an over-reliance on digital solutions to systemic problems such as climate change ('techno-solutionism'). Such technologies come at a cost: environmental, social and material. We unpack topics arising from "The True Cost of ICT: From Materiality to Techno-Solutionism (TCICT)", a workshop held at the International ICT for Sustainability (ICT4S) conference 2024 in Stockholm, Sweden -- exploring, as a matter of global climate injustice, the drivers and material dependencies of these technologies. We point to the importance of addressing ICT's impacts as a system, rather than purely in terms of efficiency and energy use. We conclude by calling to build a community of like-minded and critical colleagues to address the intersectional climate impacts of the semiconductor industry and the techno-solutionism it embodies., Comment: This position paper and extended abstract is accepted for presentation at LOCO '24: 1st International Workshop on Low Carbon Computing, 2024-12-03, in Glasgow, UK

As Information and Communication Technology (ICT) use has become more prevalent, there has been a growing concern in how its associated greenhouse gas emissions will impact the climate. Estimating such ICT emissions is a difficult undertaking due to its complexity, its rapidly changing nature, and the lack of accurate and up-to-date data on individual stakeholder emissions. In this paper we provide a framework for estimating ICT's carbon footprint and identify some of the issues that impede the task. We attempt to gain greater insight into the factors affecting the ICT sector by drawing on a number of interviews with industry experts. We conclude that more accurate emissions estimates will only be possible with a more more detailed, industry informed, understanding of the whole ICT landscape and much more transparent reporting of energy usage and emissions data by ICT stakeholders.

A third of greenhouse gas emissions are attributable to the food sector. A shift in dietary habits could reduce these by half. Engaging and empowering consumers is vital to this critical shift; yet, if we get the framing wrong, we might cause distress or eco-anxiety, impeding initial engagement as well as longer-term diet change. Evoking joy is a powerful yet under-explored motivator to overcome psychological barriers and support pro-environmental attitudes. This pictorial presents the outcomes of a one-day workshop as a series of speculative ideas in the form of an annotated portfolio, highlighting design qualities and interaction mechanisms that afford joy and sustainability in food choices. Our contribution will inspire HCI researchers and designers to reposition joy as a fundamental value to sustainability communication, Comment: Pictorial

In this report, we examine the available evidence regarding ICT's current and projected climate impacts. We examine peer-reviewed studies which estimate ICT's current share of global greenhouse gas (GHG) emissions to be 1.8-2.8% of global GHG emissions. Our findings indicate that published estimates all underestimate the carbon footprint of ICT, possibly by as much as 25%, by failing to account for all of ICT's supply chains and full lifecycle (i.e. emissions scopes 1, 2 and fully inclusive 3). Adjusting for truncation of supply chain pathways, we estimate that ICT's share of emissions could actually be as high as 2.1-3.9%. There are pronounced differences between available projections of ICT's future emissions. These projections are dependent on underlying assumptions that are sometimes, but not always, made explicit - and we explore these in the report. Whatever assumptions analysts take, they agree that ICT will not reduce its emissions without a major concerted effort involving broad political and industrial action. We provide three reasons to believe ICT emissions are going to increase barring a targeted intervention, and we note that in light of these, it seems risky to assume that ICT will, by default, assist in the attainment of climate targets. Based on our analysis, we find that not all carbon pledges in the ICT sector are ambitious enough to meet climate targets. We explore the underdevelopment of mechanisms for enforcing sector-wide compliance, and contend that without a global carbon constraint, a new regulatory framework is required to keep the ICT sector's carbon footprint in alignment with the Paris Agreement. We further contend that a global carbon constraint should be viewed as a significant opportunity for the ICT sector, as efficiencies within and enabled by ICT would be even greater enablers of productivity and utility than they are today.
