A new study reveals that AI emissions could surpass pollution from all 35 million vehicles in California by 2030
This growing concern has prompted California Governor Gavin Newsom to address the issue and explore strategies to balance technological progress with environmental sustainability.
As the home to 32 of the world’s 50 largest AI companies—including names like OpenAI, Anthropic, and Databricks—California plays a pivotal role in the development of AI technologies.
Governor Newsom acknowledges the state’s position at the forefront of this technological revolution but also warns about the unique challenges it faces due to increased energy demands and resource consumption.
On December 16, Newsom emphasized that California must stay competitive in the AI industry while also taking steps to address its environmental impact.

The Environmental Costs of AI: A Hidden Crisis

One of the most concerning issues related to AI’s growth is its environmental footprint.
According to research from the University of California–Riverside (UC Riverside) and the California Institute of Technology (Caltech), the rapid increase in AI demand is causing significant air pollution.
The energy consumption required to power AI data centers—where massive amounts of computational power are needed for training machine learning models—is contributing to a rise in harmful pollutants like nitrogen dioxide and sulfur dioxide.
These pollutants are known to cause severe health problems and are often overlooked when discussing the environmental impact of AI.
Shaolei Ren, an associate professor at UC Riverside and one of the study’s authors, explains that the pollutants generated by AI computing are the same types of particles found in car emissions.
These pollutants, which can penetrate deep into the lungs, contribute to a range of respiratory and cardiovascular problems.
The research finds that training AI models can produce pollution equivalent to making over 10,000 round trips between Los Angeles and New York City.
In 2023 alone, the health effects of AI-related pollution were comparable to the emissions from one-third of California’s entire vehicle fleet. By 2030, AI-driven emissions could exceed those of cars on California’s roads.
A Growing Problem: More Data Centers, More Pollution

The study suggests that the expansion of AI will dramatically increase the energy needed for data centers, which house the computer servers responsible for AI processing.
Energy consumption in these centers is expected to nearly triple by 2030, which could account for nearly 12% of all U.S. energy usage.
This surge in electricity demand is already placing pressure on power grids and contributing to higher water usage, as cooling systems for data centers often rely on large amounts of water.
Another significant concern is the reliance on fossil fuel-powered plants and backup diesel generators to supply energy to these data centers.
Diesel generators, in particular, emit up to 600 times more particulates than natural gas plants, worsening air quality.
As these facilities operate continuously, their environmental footprint grows, contributing to both air pollution and climate change.
The study highlights the need for a more thorough assessment of the health and environmental costs associated with AI’s rise, urging policymakers to consider these hidden consequences in their decisions.
Health Impacts: A Looming Public Crisis

The health implications of AI-linked pollution are dire. The study estimates that by 2030, the air pollution generated by AI could lead to about 600,000 new cases of asthma and more than 1,300 premature deaths annually in the United States.
These impacts would come with an economic cost exceeding $20 billion per year in public health expenses.
The broader effects of air pollution are well-documented, including links to heart disease, strokes, and other life-threatening conditions.
In 2019, the World Health Organization reported that air pollution was responsible for approximately 4.2 million deaths globally, making it the second leading cause of noncommunicable diseases, right after tobacco use.
In the U.S., the American Lung Association’s 2024 State of the Air report revealed that 40% of Americans live in areas with unhealthy levels of particulate pollution.
These pollutants don’t just stay local; they can travel long distances, affecting communities hundreds of miles away from their source.
This means that AI emissions from California could impact residents across the country, highlighting the need for national solutions to address this growing issue.
Proactive Solutions: Mitigating the Impact
www.smartsangat.com
Governor Newsom and the researchers stress that while AI has the potential to revolutionize many industries, its growth must be managed carefully to avoid exacerbating the environmental and public health crises.
Newsom has proposed that small modular nuclear reactors (SMRs) could help provide a carbon-free energy source to power data centers.
These reactors have smaller footprints and lower upfront costs compared to traditional nuclear plants, making them a potentially viable solution for addressing California’s energy needs without contributing to carbon emissions.
Ren and his colleagues also recommend other strategies, such as balancing workloads to take advantage of renewable energy sources like solar power.
Data centers could be designed to align their operations with times when solar energy production is at its peak, reducing the reliance on fossil fuels.
The researchers suggest that AI companies should be required to report their pollution levels and energy consumption, helping policymakers better understand the full environmental impact of their operations.
A more comprehensive cost-benefit analysis could help guide future decisions and ensure that AI’s benefits are realized without compromising public health.
Moving Forward: A Call for Equitable Solutions

Adam Wierman, a professor at Caltech and a co-author of the study, emphasizes the need for a balanced approach to AI’s development.
While AI has the potential to increase productivity, improve efficiency, and reduce costs across various industries, it is crucial that the negative consequences of this technology are not ignored.
The benefits of AI must be weighed against its environmental and health impacts, and efforts should be made to share these costs equitably, ensuring that vulnerable communities are not disproportionately affected.
As the AI industry continues to grow, it is clear that addressing its environmental and public health impact will require collaboration between tech companies, government officials, and researchers.
California’s leadership in AI technology comes with a responsibility to mitigate its negative effects and ensure that the state’s ambitious green growth goals are not undermined by the very innovations it seeks to promote.
California faces a complex challenge as it navigates the intersection of technological advancement and environmental responsibility.
The state must strike a delicate balance between fostering the AI industry and addressing the associated health and environmental risks.
With thoughtful planning and innovative solutions, California can continue to lead in AI development while also protecting the health of its residents and the planet.
