New research from scientists at the University of Waterloo and the Georgia Institute of Technology challenges the prevailing notion that artificial intelligence (AI) significantly contributes to global greenhouse gas emissions. The study indicates that AI’s impact on worldwide pollution is minimal and suggests that increased adoption of the technology may actually promote environmental and economic progress.
The researchers analyzed U.S. economic data alongside estimates of AI tool usage across various industries to project environmental outcomes stemming from the anticipated rise in AI adoption. According to the U.S. Energy Information Administration, 83 percent of the nation’s economic activity is dependent on fossil fuels such as petroleum, coal, and natural gas, which generate greenhouse gases when combusted. However, the study found that the total energy consumption attributed to AI in the United States is comparable to Iceland’s electricity use, categorizing this figure as negligible on both national and global scales.
“It is important to note that the increase in energy use is not going to be uniform,” said Dr. Juan Moreno-Cruz, a professor in the Faculty of Environment at Waterloo and a Canada Research Chair in Energy Transitions. “It’s going to be felt more in the places where electricity is produced to power the data centers. If you look at that energy from the local perspective, that’s a big deal because some places could see double the amount of electricity output and emissions. But at a larger scale, AI’s use of energy won’t be noticeable.”
While the study did not delve into the economic ramifications for specific communities hosting data centers, the researchers identified several optimistic outcomes. “For people who believe that the use of AI will be a major problem for the climate and think we should avoid it, we’re offering a different perspective,” Moreno-Cruz added. “The effects on climate are not that significant, and we can use AI to develop green technologies or to improve existing ones.”
The findings emerged from a comprehensive review conducted by Moreno-Cruz and Dr. Anthony Harding, who examined various economic sectors, the types of jobs within those sectors, and the proportion of tasks that could potentially be automated through AI. They plan to apply the same analytical framework to other countries, aiming to assess how the adoption of AI might shape environmental outcomes on a global scale.
The study contributes to an ongoing debate about the environmental implications of advanced technologies. As AI continues to permeate different sectors, understanding its energy consumption and potential for fostering sustainable practices will become increasingly critical. The researchers’ insights may encourage further exploration into how AI can not only mitigate its impact on greenhouse gas emissions but also drive innovations in green technology.
With discussions surrounding climate change and sustainability growing more urgent, this research offers a fresh perspective that could influence policy and investment decisions in AI and clean technology. As industries adapt to new technological landscapes, the balance between innovation and environmental responsibility will remain a pivotal challenge for policymakers and business leaders alike.
