Observational studies across countries associate more AI with lower carbon emissions and lower physical climate risk. TRV-2026-0377TRV-2026-1231 Against that, a model projects US AI servers adding water use and emissions through 2030, and the biggest tech companies' reported emissions have risen with datacentre construction. TRV-2026-0474TRV-2026-0296
A systematic review of more than 35 studies shows wearable and related sensors detected lameness in grazing sheep with up to 85% accuracy. TRV-2026-0951 A validated comparison found a machine learning correction roughly doubled the skill of ECMWF's AI forecasting model at two to six weeks and beat dynamical models from six operational centres in a 2025 real time competition. TRV-2026-1465 In a study of 1,163 advanced wheat breeding lines, cutting 570,441 genetic markers to a few hundred per trait raised prediction accuracy 14.4% over random markers. TRV-2026-2110 Gap filled satellite data matched ground monitors for hourly PM2.5 in the 50 most populous US counties (daily R2 0.85). TRV-2026-1611
Microsoft, Amazon and Google's combined emissions rose from about 101m to 119m tonnes of CO2e in the year to March 2026, and company reports link the rise to datacentre construction for AI and cloud. TRV-2026-0296 Global Energy Monitor reports US gas capacity under construction jumped 76% in early 2026, with about half of new capacity tied to AI datacentres. TRV-2026-0884 A study of China's 2000 to 2024 data found AI robotics did not help lower CO2 emissions. TRV-2026-2379 Tested on countries they had not seen, emission classification models reached only 0.637 to 0.676 accuracy, against 0.91 on a random split. TRV-2026-1743
Many tools were tested only on datasets or simulations: an apple leaf system reported 99.95% accuracy but not on farms, and a retrofit planner for UK public buildings ran 30.03 times faster only in simulated cases. TRV-2026-0262TRV-2026-1729 Estimates of AI's water and carbon cost are modelled, not metered: one paper puts GPT-3 training at 5.4 million liters of water, and data center reports do not separate AI from other workloads. TRV-2026-2359TRV-2026-0433 Claims of local harm from planned datacentres rest mostly on residents' accounts; in East Fishkill the project is at an exploratory stage and impacts on rates, water and jobs remain unmeasured. TRV-2026-1401TRV-2026-1555
Panel data from 67 countries associate greater AI development with significantly lower carbon emissions, yet a study of China's 2000 to 2024 data found AI robotics did not help lower CO2 emissions. TRV-2026-0377TRV-2026-2379 A review of 146 studies found that in four countries technical performance and investment alone did not ensure sustainable outcomes. TRV-2026-1905 Among Chinese listed firms, real AI investment was associated with lower pollution intensity, while AI talk beyond actual investment was associated with higher intensity. TRV-2026-2116
Projections and company reports point to rising emissions and water use, though most of the figures are modelled estimates rather than metered measurements. TRV-2026-0474TRV-2026-0296TRV-2026-0433

Across 51 countries from 1996 to 2023, greater AI use was associated with lower physical climate risks, with a stronger effect where those risks were higher.
A study of G20 economies from 2015 to 2023 found that higher AI readiness was linked to better national sustainability performance, with a larger association than FinTech or Blockchain.
In panel data from 67 countries, greater AI development was associated with significantly lower ecological footprints and carbon emissions and faster energy transitions, with the strongest link for energy transitions.
A review of 146 studies found that AI's expansion in energy systems also raises electricity and infrastructure demand, and that in four countries, technical performance and investment alone did not ensure sustainable outcomes.
A review of 103 studies found AI environmental research centres on training and deployment energy, while water use, Scope 3 value-chain impacts and end-of-life hardware are thinly covered and cloud dashboards cannot be compared.
One review in this topic printed a pooled result: one figure calculated across many studies. They are the reviews’ own numbers, checked word for word against their abstracts. They often measure different things, so they are listed side by side, not added up.

A random-effects model shows a large, pooled effect (Hedges’ g = 0.92; 95% CI: 0.78–1.06; p < 0.001) for within-domain performance/sustainability outcomes.
Models detect microplastics, soil metals and wastewater sources well in lab or regional tests, but they miss sites and often overstate accuracy outside their training data. TRV-2026-1989TRV-2026-1744TRV-2026-0643TRV-2026-0932

A review of 80 publications from 2020–2025 found that Morocco's climate-resilience AI research is limited by sparse ground observations, restricted institutional data, limited spatial transfer testing and minimal explainable AI, constraining reproducibility and operational uptake.
