Google’s newest annual environmental report reveals the true affect its current forays into synthetic intelligence has had on its greenhouse fuel emissions.
The enlargement of its knowledge centres to help AI developments contributed to the corporate producing 14.3 million tonnes of carbon dioxide equivalents in 2023. This represents a 48% improve over the equal determine for 2019 and a 13% improve since 2022.
“This outcome was primarily as a consequence of will increase in knowledge middle power consumption and provide chain emissions,” the report’s authors wrote.
“As we additional combine AI into our merchandise, decreasing emissions could also be difficult as a consequence of rising power calls for from the higher depth of AI compute, and the emissions related to the anticipated will increase in our technical infrastructure funding.”

Google claims it can not distinguish the element of general knowledge centre emissions that AI is liable for
In 2021, Google pledged to succeed in net-zero emissions throughout all its operations and worth chain by 2030. The report states this aim is now deemed “extraordinarily bold” and “would require (Google) to navigate vital uncertainty.”
The report goes on to say the environmental affect of AI is “complicated and tough to foretell,” so the corporate can solely publish knowledge centre-wide metrics as an entire, which lumbers in cloud storage and different operations. This implies the environmental harm inflicted particularly on account of AI coaching and use in 2023 is being stored underneath wraps for now.
That being mentioned, in 2022, David Patterson, a Google engineer, wrote in a weblog, “Our knowledge reveals that ML coaching and inference are solely 10%–15% of Google’s complete power use for every of the final three years.” Nonetheless, this proportion is more likely to have elevated since then.

Why AI is liable for tech firms’ elevated emissions
Like most of its opponents, Google has launched quite a few AI tasks and options over the past 12 months, together with Gemini, Gemma, Overviews and picture technology in Search and AI safety instruments.
AI methods, notably these concerned in coaching giant language fashions, demand substantial computational energy. This interprets into larger electrical energy utilization and, consequently, extra carbon emissions than regular on-line exercise.

In accordance with a examine by Google and UC Berkeley, coaching OpenAI’s GPT-3 generated 552 metric tonnes of carbon — the equal to driving 112 petrol automobiles for a 12 months. Moreover, research estimate {that a} generative AI system makes use of round 33 instances extra power than machines working task-specific software program.
Final 12 months, Google’s complete knowledge centre electrical energy consumption grew by 17%, and whereas we don’t know what quantity of this was as a consequence of AI-related actions, the corporate did admit it “count on(s) this pattern to proceed sooner or later.”
Google is just not the primary of the massive tech organisations to disclose that AI developments are taking a toll on its emissions and that they’re proving tough to handle. In Could, Microsoft introduced that its emissions have been up 29% from 2020, primarily on account of constructing new knowledge centres. “Our challenges are partly distinctive to our place as a number one cloud provider that’s increasing its knowledge facilities,” Microsoft’s environmental sustainability report mentioned.
Leaked paperwork seen by Enterprise Insider in April reportedly present Microsoft has obtained greater than 500MW of extra knowledge centre area since July 2023 and that its GPU footprint now helps reside “AI clusters” in 98 places globally.
4 years in the past, Microsoft President Brad Smith referred to the corporate’s pledge to turn into carbon unfavourable by 2030 as a “moonshot.” Nonetheless, in Could, he admitted that “the moon has moved” since then and is now “greater than 5 instances as far-off,” through Bloomberg’s Zero podcast.
Alex de Vries, the founding father of digital pattern evaluation platform Digiconimist, which tracks AI sustainability, thinks that Google and Microsoft’s environmental studies show that tech bosses should not taking sustainability as severely as AI growth. “On paper they could say so, however the actuality is that they’re at the moment clearly prioritising development over assembly these local weather targets,” he instructed TechRepublic in an electronic mail.
“Google is already struggling to gasoline its rising power demand from renewable power sources. The carbon depth of each MWh consumed by Google is rising quickly. Globally we solely have a restricted provide of renewable power sources accessible and the present trajectory of AI-related electrical energy demand is already an excessive amount of. One thing should change drastically to make these local weather targets achievable.”
Google’s skyrocketing emissions might even have a trickle-down affect on the companies utilizing its AI merchandise, which have their very own environmental targets and laws to adjust to. “If Google is a part of your worth chain, Google’s emissions going up additionally means your Scope 3 emissions are going up,” de Vries instructed TechRepublic.
How Google is managing its AI emissions
Google’s environmental report highlights quite a few methods the corporate is managing the power calls for of its AI developments. Its newest Tensor Processing Unit, Trillium, is over 67% extra power environment friendly than the fifth technology, whereas its knowledge centres are over 1.8 instances extra energy-efficient than typical enterprise knowledge centres.
Google’s knowledge centres additionally now ship roughly 4 instances as a lot computing energy with the identical quantity {of electrical} energy in comparison with 5 years in the past.
In March 2024 at NVIDIA GTC, TechRepublic spoke with Mark Lohmeyer, vice chairman and basic supervisor of compute and AI/ML Infrastructure at Google Cloud, about how its TPUs are getting extra environment friendly.
He mentioned, “If you concentrate on working a extremely environment friendly type of accelerated compute with our personal in-house TPUs, we leverage liquid cooling for these TPUs that permits them to run sooner, but in addition in a way more power environment friendly and because of this a more economical method.”
Google Cloud additionally makes use of software program to handle up-time sustainably. “What you don’t need to have is a bunch of GPUs or any kind of compute deployed utilizing energy however not actively producing, , the outcomes that we’re searching for,” Lohmeyer instructed TechRepublic. “And so driving excessive ranges of utilisation of the infrastructure can be key to sustainability and power effectivity.”
Google’s 2024 environmental report says the corporate is managing the environmental affect of AI in 3 ways:
- Mannequin optimisation: For instance, it boosted the coaching effectivity of its fifth-generation TPU by 39% with strategies that speed up coaching, like quantisation, the place the precision of numbers used to signify the mannequin’s parameters is lowered to lower the computational load.
- Environment friendly infrastructure: Its fourth-generation TPU was 2.7 instances extra energy-efficient than the third technology. In 2023, Google’s water stewardship program offset 18% of its water utilization, of which a lot goes into cooling knowledge centres.
- Emissions discount: Final 12 months, 64% of the power consumed by Google’s knowledge centres got here from carbon-free sources, which embody renewable sources and carbon seize schemes. It additionally deployed carbon-intelligent computing platforms and demand response capabilities at its knowledge centres.
As well as, Google’s AI merchandise are being designed to handle local weather change on the whole, like fuel-efficient routing in Google Maps, flood prediction fashions, and the Inexperienced Mild software that helps engineers optimise the timing of visitors lights to scale back stop-and-go visitors and gasoline consumption.
AI demand might overwhelm emissions targets
Google states the electrical energy consumption of its knowledge centres — which energy its AI actions, amongst different issues — at the moment solely makes up about 0.1% of world electrical energy demand. Certainly, in keeping with the Worldwide Power Company, knowledge centres and knowledge transmission networks are liable for 1% of energy-related emissions.
Nonetheless, that is anticipated to rise considerably within the subsequent few years, with knowledge centre electrical energy consumption projected to double between 2022 and 2026. In accordance with SemiAnalysis, knowledge centres will devour about 4.5% of world power demand by 2030.
Appreciable quantities of power are required for the coaching and operation of AI fashions in knowledge centres, however the manufacturing and transportation of the chips and different {hardware} additionally contribute. The IEA has estimated that AI particularly will use 10 instances as a lot electrical energy in 2026 because it did in 2023, because of the rising demand.

Knowledge centres additionally want large quantities of water for cooling and much more so when working energy-intensive AI computations. One examine from UC Riverside discovered the quantity of water withdrawn for AI actions might attain the equal of half of the U.Ok.’s annual consumption by 2027.
Elevated demand for electrical energy might push tech firms again to non-renewable power
Tech firms have lengthy been giant traders in renewable power, with Google’s newest environmental report stating it bought greater than 25 TWh-worth in 2023 alone. Nonetheless, there are considerations the skyrocketing demand for power on account of their AI pursuits will preserve coal and oil-powered vegetation in enterprise that will have in any other case been decommissioned.
For instance, in December, county supervisors in northern Virginia authorised for as much as 37 knowledge centres to be constructed throughout simply 2,000 acres, resulting in proposals for increasing coal energy utilization.
