The pith

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

The reading

This paper argues that the widely held belief in Moore's Law—the steady doubling of transistors and with it ever-greater efficiency—is actively undermining efforts to reduce the climate impact of information and communication technology (ICT). The authors claim that efficiency gains do not lower ICT's total energy and material footprint, because they feed economic growth, more devices, larger networks, and bigger data centres; this is a rebound effect. They contend that this 'techno-solutionist' faith in future efficiency distracts from the present, growing, absolute costs of digital infrastructure, including carbon emissions, mining, water use, and social injustice in the Global South. If the argument is right, climate policy for ICT should shift from efficiency ratios to systemic limits on absolute consumption, organised around justice rather than innovation. The paper is a position piece based on a workshop of sustainability researchers, not a new empirical study.

What carries the argument

The mechanism that carries the argument is the rebound effect, applied to Moore's Law. Moore's Law is the observation that the number of transistors on an integrated circuit roughly doubles every two years, which has historically delivered large gains in computational performance and energy efficiency. The authors argue that these gains are not banked as savings; they are reinvested in new products, higher capacity networks, larger data centres, and more capable AI systems, so total energy and material consumption grows. The paper names this pattern 'techno-solutionism'—the assumption that technological innovation can solve problems such as climate change without questioning the growth model that creates them. This assumption is what the paper tries to dismantle, by pointing to absolute consumption and justice concerns that efficiency ratios hide.

What would settle it

A sustained decade in which global ICT energy use and material throughput declined while computational capacity continued to grow would contradict the central claim. So would a careful accounting showing that efficiency improvements in a major ICT segment produced a net absolute reduction in energy after accounting for induced demand. The paper does not supply such a calculation, leaving this an open empirical question.

Watch

Extended reading notes

Core claim

On the paper's own terms, the central claim is that Moore's Law and the ideology of techno-solutionism it sustains are not a solution to ICT's climate problem but part of the cause. The authors do not dispute that each new chip generation delivers more computation per unit of energy; they argue that this very efficiency is an engine of growth, so the absolute energy, material, and social costs of ICT keep rising despite, and because of, efficiency improvements. Data centres, cryptocurrencies, and AI are already consuming almost 2% of global electricity, with demand projected to double by 2026, while efficiency metrics such as PUE and WUE celebrate ratios rather than confronting total consumption. The paper concludes that framing the problem in terms of energy, emissions, and efficiency serves the industry's growth narrative, and that the debate must be reframed around international justice, material limits, and the full societal harm of digital infrastructure.

Load-bearing premise

The whole argument rests on the premise that gains in efficiency do not reduce total energy and material use but instead fuel more consumption; if efficiency ever translated into shrinking absolute demand, the central claim would no longer hold.

Editorial extensions

If this is right

  • Climate policy for ICT should target absolute caps on energy and material use, not efficiency ratios like PUE or WUE.
  • Efficiency-focused narratives and voluntary industry metrics will keep failing because they ignore the growth rebound effect.
  • Planned expansions of data centres and AI infrastructure need to be weighed against competing social needs for renewable energy, not assumed beneficial.
  • The debate must include justice dimensions: who bears the cost of mining, water use, and displacement for digital infrastructure in the Global South.
  • Education and research in technology should question the 'innovation at any cost' mindset that trains engineers to ignore environmental and social externalities.

Reading between the lines

Editorial extensions of the paper, not claims the author makes directly.

  • A testable prediction follows: regions or sectors that adopt strong absolute energy or material caps for ICT should show lower total impact than those relying solely on efficiency improvements, even after controlling for economic growth.
  • If the rebound logic is right, the same argument applies beyond ICT to other efficiency-driven technologies such as electric vehicles or renewable energy: efficiency alone without absolute limits may not deliver climate goals.
  • The paper's framing implies that replacing frequent hardware upgrades with longer-lasting, repairable devices is a more effective climate strategy than waiting for the next efficiency-generating chip generation, an extension the authors gesture at but do not develop.
  • A concrete accounting exercise—tracking global ICT energy and material footprints against compute capacity over the past two decades—would give the debate an empirical anchor the position paper currently lacks.

Referee Report

3 major / 4 minor

Summary. This paper argues that the Moore's Law narrative of relentless efficiency improvement is a core driver of techno-solutionism and that this belief actively undermines meaningful climate action on ICT. Drawing on a workshop held at ICT4S 2024, the authors synthesize discussions about ICT's energy, material, and social costs and call for a shift from efficiency-centered metrics to systemic, justice-based approaches that address absolute consumption. The paper is written as a position/workshop report rather than an empirical study, and its central claim is that focusing on future efficiency gains distracts from present absolute impacts.

Significance. If the central causal claim were established, the paper would have significant implications for ICT sustainability policy, suggesting that efficiency-centered policies are not merely insufficient but counterproductive. The paper usefully collects and connects evidence on growing ICT energy demand, material dependencies, and social injustices, and it gives due attention to global climate justice. Its strengths include a clear call to broaden the debate beyond energy and emissions and an explicit connection to previous scholarship on digital rebound and techno-solutionism. However, the paper presents no original data or derivation for its headline claim, and the causal mechanism—that belief in Moore's Law actively impedes action—is asserted rather than demonstrated. The paper itself uses the phrase 'we hypothesise' in Section 1, which is in tension with the definitive title and abstract.

major comments (3)
  1. [Section 1] The title and abstract assert that belief in Moore's Law 'is undermining' ICT climate action, while Section 1 states 'we hypothesise that the techno-solutionist paradigm ... is dangerous.' This mismatch is load-bearing: the paper provides no evidence that this belief causes a lack of action, as opposed to being correlated with it. To support the causal claim, the authors would need, for example, decision-maker statements, policy documents, or longitudinal data linking efficiency narratives to investment and regulatory choices. As written, the paper's evidence only shows that ICT impacts are growing, which is compatible with many other explanations.
  2. [Section 2.1] The rebound-effect premise is essential to the argument but is asserted rather than established. The sentence 'this increase in capability also feeds economic and market growth for new ICT products and infrastructures, leading to further higher capacity including networks and data centres' is presented as fact, but the cited sources [4, 11] discuss digital rebound without quantifying its strength for ICT as a whole. If rebound is weak, saturating, or merely partially offsetting, then efficiency gains could still lower absolute impacts, and the paper's central claim would fail. The authors need either to provide empirical estimates of rebound strength or to explicitly frame the argument as conditional on strong rebound.
  3. [Section 2 and Call to action] The paper moves from the observation that efficiency metrics alone are inadequate to the conclusion that efficiency-centered approaches are actively harmful. This is a logical gap: even under substantial rebound, efficiency improvements might be a necessary (though not sufficient) component of a broader strategy. The argument would be strengthened by explicitly considering partial-rebound or saturating-rebound scenarios and by explaining why such scenarios are implausible for ICT. Without this, the claim that efficiency talk 'actively impedes' action remains an overstatement.
minor comments (4)
  1. [Abstract] There are typesetting artifacts in the abstract, such as 'w ith', 'Thisincludes', and 'efficiency'; these should be corrected in the final version.
  2. [References] Reference [10] appears to have a mismatch between the cited title ('Marc Andreessen just dropped a Techno-Optimist Manifesto...') and the URL, which points to an article titled 'The True Nature of Moore's Law'. Please verify and correct the reference.
  3. [Section 2.3] The claim that water-use metrics such as WUE, like PUE, emphasize ratios over absolute consumption would benefit from a supporting citation, and the acronym WUE should be spelled out consistently.
  4. [Call to action] The phrase 'the three E's of energy, emissions and efficiency' is used without a source or definition; please clarify whether this is an established taxonomy or an introduced one.

Circularity Check

0 steps flagged · score 2.0 of 10

No circular derivation: the central claim is argued from external rebound-effect literature and IEA projections, not from fitted parameters or self-referential definitions; minor self-citations are present but not load-bearing.

full rationale

This is a position paper, not a derivation. The load-bearing premise that efficiency gains produce rebound and fail to reduce absolute ICT energy and material consumption is cited to external sources [4, 11], and absolute demand growth is supported by IEA data [1] and industry reporting [16]. The paper makes no quantitative predictions and fits no parameters, so there is no fitted-input-called-prediction or self-definitional step. Self-citations appear ([6] Freitag et al. for ICT GHG estimates, [18] Mitra et al. for the claim that relentless ICT innovation drives techno-solutionism, and [17], [19] on education and anticolonial perspectives), but these are supporting references for a position, not a chain that reduces the conclusion to its own assertion. Section 2's sentence 'Relentless ICT innovation (epitomised by Moore’s Law) is probably a key driver behind this ideology [18]' relies on the authors' prior work, yet the surrounding argument and external rebound citations carry the paper's main claim. Thus no circular step is exhibited; score 2 reflects the minor self-citation, not circularity.

Assumptions & free parameters 0 free parameters · 4 assumptions · 0 invented entities

No free parameters or invented entities. The paper relies on cited empirical estimates and on domain assumptions about rebound effects and the prevalence of techno-solutionism; these are not established by original data in the paper.

assumptions (4)
  • domain assumption Efficiency gains in ICT lead to rebound effects that increase net energy and material consumption, so absolute impacts do not fall.
    Section 2.1 and the Introduction invoke 'a classic rebound effect' citing [4, 11]; this paper provides no original measurement, and the causal strength of rebound is load-bearing for the claim that Moore's Law belief undermines climate action.
  • domain assumption Techno-solutionism, the belief that technological solutions can solve systemic problems, is widespread and is a key driver of inadequate climate action.
    Introduction and Section 2 assert this as context; it is a framing assumption drawn from prior literature [9, 10, 22], not tested here.
  • domain assumption ICT GHG emissions in 2021 were equivalent to global air travel and data centre electricity demand could double by 2026.
    Section 2.1 cites [6] and [1]; these external estimates anchor the severity claim but are not verified in this paper.
  • domain assumption Workshop participants and discussions provide a representative basis for the field-level conclusions.
    Section 2 describes 30+ attendees and thematic synthesis; the paper generalizes from this sample to the ICT sector.

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.
