Abstract

As AI systems proliferate, their greenhouse gas emissions are an increasingly important concern for human societies. In this article, we present a comparative analysis of the carbon emissions associated with AI systems (ChatGPT, BLOOM, DALL-E2, Midjourney) and human individuals performing equivalent writing and illustrating tasks. Our findings reveal that AI systems emit between 130 and 1500 times less CO2e per page of text generated compared to human writers, while AI illustration systems emit between 310 and 2900 times less CO2e per image than their human counterparts. Emissions analyses do not account for social impacts such as professional displacement, legality, and rebound effects. In addition, AI is not a substitute for all human tasks. Nevertheless, at present, the use of AI holds the potential to carry out several major activities at much lower emission levels than can humans.

AI snapshot

Written from the paper’s full text.

TL;DR

This paper compares the carbon emissions of AI systems and humans performing equivalent writing and illustration tasks, finding that AI emits far less CO2e per page or image under the study’s assumptions. It argues that concerns about AI’s emissions should be tempered by the much larger human footprint for these tasks, while noting social, legal, and rebound-effect caveats.

Key findings

  • AI writing emits 130–1500 times less CO2e per page of text than human writers: BLOOM is 1400× less impactful than a US resident and 180× less than an India resident; ChatGPT is 1100× less than a US resident and 130× less than an India resident.
  • AI illustration emits 310–2900 times less CO2e per image than human illustrators: DALL-E2 is ~2500× less than a US-based artist and ~310× less than an India-based artist; Midjourney is ~2900× less than a US artist and ~370× less than an India-based artist.
  • Per-query/per-image AI emissions are on the order of grams: ChatGPT ~2.2 g CO2e per query, BLOOM ~1.6 g per query, DALL-E2 ~2.2 g per query, and Midjourney ~1.9 g CO2e per image.
  • Human comparison values are much larger: a US resident writing a 250-word page is ~1400 g CO2e, an India resident ~180 g; a US-based illustrator is ~5500 g CO2e per image, an India-based illustrator ~690 g.

Methods

  • The study conducted numerical analyses following life cycle assessment stages: goal and scope, inventory analysis, impact assessment, and interpretation.
  • It compared four AI systems—ChatGPT, BLOOM, DALL-E2, and Midjourney—against human writing and illustration, including AI hardware/energy use but excluding software development and personnel, and using human annual carbon footprints apportioned by time spent on the task.
  • Data came from previously published sources including peer-reviewed articles, government reports, and databases; the authors also used ChatGPT for drafting/editing but state that data analysis, calculations, and conclusions were their own.

Limitations

  • The paper states results are not generalizable to all contexts, AI is not a substitute for all human tasks, and some tasks remain more efficient for humans (e.g., an in-depth, heavily referenced original article is beyond current AI; drawing a stick figure may be faster for a human).
  • The paper states it does not account for social impacts such as professional displacement, legality of training materials, and rebound effects, and notes future technology and societal changes will alter the AI/human emissions ratio.
  • Evident from the text: several estimates rely on assumptions or informal sources, including Mark Twain’s 300 words/hour as average writing speed, a $200 project cost and $62.50/hour illustrator rate to infer 3.2 hours per illustration, Midjourney CEO comments about petaoperations, an informal online ChatGPT estimate, and the EPA calculator’s simplification of CO2e conversion.

Percentages, sums and reported differences re-computed from the paper’s own numbers.

  • BLOOM's amortized training emissions are understated

    Minor

    At the stated usage of 300 million queries per month, 50.5 metric tons of training emissions amount to about 0.168 g per query, not 0.10 g. In the check, the denominator is expressed in millions of queries, so metric tons divided by millions of queries gives grams per query.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-09.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-09.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
