On July 1, 2025, The New York Times reported a pivotal moment in U.S. AI regulation: the Senate voted 99-1 to reject an amendment that would have imposed a 10-year moratorium on state-level AI laws. This decision, a significant win for consumer advocates and Democrats, ensures that states retain the authority to regulate artificial intelligence (AI) without federal preemption. The vote underscores the growing recognition of AI’s transformative potential and its associated risks, prompting states to craft legislation addressing consumer protection, privacy, and ethical concerns.

However, as AI’s environmental footprint becomes increasingly apparent, some states are also beginning to address its sustainability implications. This article explores the agenda behind US state AI laws, their direct and indirect impacts on the environment, and the emerging focus on sustainable AI development.

Primary Agenda of US State AI Laws

The primary focus of state AI laws is to safeguard consumers and ensure ethical AI use. According to the New York Times article, nearly all 50 states have introduced AI-related bills over the past year, targeting issues such as consumer privacy, AI-generated child sexual abuse material, and deepfake videos of political candidates.

For example, states have implemented measures to strengthen privacy protections, ensuring that AI systems do not misuse personal data. Others have outlawed deepfakes to prevent misinformation in political campaigns, while some have banned AI-generated harmful content to protect vulnerable populations. Senator Maria Cantwell emphasized the importance of state-level oversight, noting that these laws enable states to combat robocalls and deepfakes and ensure the safety of autonomous vehicles. This agenda reflects a commitment to addressing immediate societal risks posed by AI’s rapid proliferation.

The defeat of Senator Ted Cruz’s amendment, which sought to impose a federal moratorium on state AI laws, was driven by concerns from consumer groups, state attorneys general, and child safety advocates. These stakeholders argued that a moratorium would allow AI companies to develop untested and potentially dangerous technologies without sufficient oversight. By preserving state authority, the Senate’s decision empowers states to tailor regulations to their specific needs, fostering a diverse and responsive regulatory landscape.

Environmental Impact of AI

AI’s environmental footprint is a growing concern, particularly due to the energy-intensive nature of developing and deploying large AI models. Data centres, which power AI computations, consume vast amounts of electricity, often sourced from fossil fuels, leading to significant carbon emissions. A 2019 study from the University of Massachusetts found that training a single large AI model can emit as much carbon dioxide as five cars over their lifetimes, equivalent to approximately 626,000 pounds of CO2. Beyond energy consumption, the production of AI hardware, such as graphics processing units (GPUs), involves mining rare earth metals and energy-intensive manufacturing processes, further contributing to environmental degradation. Additionally, data centres require substantial water for cooling, placing strain on local water resources.

Despite these challenges, AI also offers significant potential for environmental benefits. AI can optimise energy usage in smart grids, enhance the efficiency of renewable energy systems, predict climate change impacts, and improve agricultural practices to reduce waste. For instance, AI-driven models can forecast weather patterns or optimise irrigation, contributing to sustainable resource management. However, realising these benefits requires careful regulation to ensure that AI development does not exacerbate environmental harm.

Negative Impacts

• High energy consumption by data centres, often powered by fossil fuels, leading to significant carbon emissions.
• Resource-intensive hardware production, including the mining of rare earth metals.
• Water usage for cooling data centres, straining local resources.

Positive Impacts

• Optimisation of energy usage in smart grids and renewable energy systems.
• Predictive modelling for climate change mitigation and disaster response.
• Improved agricultural efficiency to reduce waste and resource use.

US State AI Laws Addressing Environmental Concerns

While most state AI laws focus on consumer protection and ethical use, some states are pioneering legislation to address AI’s environmental impact. In California, Assembly Bill 222 (AB 222), introduced by Assemblymember Rebecca Bauer-Kahan, requires data centers providing computing resources for developing covered AI models to estimate and report the total energy used in the development process. This information must be shared with developers and made publicly available, promoting transparency in AI’s energy footprint. The bill also mandates the California Energy Commission to monitor these reports, evaluate energy trends, and establish energy efficiency standards for data centres.

Additionally, AB 222 includes safeguards to prevent energy costs from being unfairly passed on to ratepayers, ensuring that the financial burden of AI infrastructure expansion is equitably distributed. These measures aim to foster sustainable AI development while protecting California’s electrical grid and consumers (California AB 222).

In Massachusetts, House Docket 4192, titled “An Act reducing emissions from artificial intelligence,” introduced by Representative David M. Rogers, directly targets AI-related emissions. Although detailed provisions are not yet fully available, the bill’s title and context suggest a focus on mitigating the environmental impact of AI technologies. This initiative reflects a growing recognition that AI’s energy consumption must be addressed to align with broader sustainability goals (Massachusetts HD 4192).

These state-level efforts complement broader calls for environmental accountability in AI. For example, the federal Artificial Intelligence Environmental Impacts Act of 2024, introduced by Senator Edward J. Markey, aimed to study and report on AI’s environmental effects but has not been reintroduced in the 119th Congress. The absence of comprehensive federal legislation has placed greater responsibility on states to address AI’s environmental footprint, with California and Massachusetts leading the way.

Potential Indirect Impacts

State AI laws that do not explicitly address environmental concerns can still indirectly influence sustainability. For instance, regulations that promote responsible AI development, such as those requiring impact assessments or transparency in AI applications, could encourage developers to consider energy efficiency and environmental impacts. Laws that limit the scope of AI applications to essential functions may reduce unnecessary computational demands, thereby lowering energy consumption. Conversely, if regulations fail to account for environmental factors, they could inadvertently allow unchecked growth in energy-intensive AI applications, exacerbating environmental harm.

Moreover, state laws that foster innovation in AI applications for sustainability—such as climate modelling, disaster response, or energy optimisation—could amplify AI’s positive environmental contributions. For example, states could incentivize the development of AI tools that enhance renewable energy systems or improve resource management, aligning regulatory frameworks with environmental goals.

Broader Context and Global Perspectives

Globally, there is a growing push to address AI’s environmental impact. The United Nations Environment Programme (UNEP) notes that over 190 countries have adopted non-binding recommendations on the ethical use of AI, including environmental considerations. However, specific policies targeting AI’s environmental footprint remain rare.

The European Union and the United States have introduced some legislation to temper AI’s environmental impact, but standardized procedures for measuring and reporting these impacts are still lacking. UNEP recommends establishing such standards, alongside promoting energy-efficient AI algorithms and renewable energy use in data centres, to mitigate AI’s environmental fallout.

In the U.S., the lack of federal AI regulation has led to a patchwork of state laws, creating both opportunities and challenges. States can experiment with innovative approaches to AI governance, including environmental regulations, but the absence of uniform standards may complicate compliance for companies operating across multiple states. As AI adoption accelerates, with over 40% of enterprise-scale businesses in the U.S. integrating AI, the need for cohesive and sustainable regulatory frameworks becomes increasingly urgent.

Conclusion

State AI laws in the U.S. are primarily driven by the need to protect consumers, ensure privacy, and prevent the misuse of AI technologies. However, as AI’s environmental impact becomes more evident, states like California and Massachusetts are taking proactive steps to address sustainability through targeted legislation. California’s AB 222 and Massachusetts’ HD 4192 represent an emerging agenda to integrate environmental considerations into AI governance, promoting transparency and efficiency in AI’s energy consumption.

Indirectly, other state AI laws can influence sustainability by shaping how AI is developed and applied. As AI continues to transform society, balancing its innovative potential with environmental responsibility will be critical. By preserving state authority to regulate AI, the Senate’s recent decision empowers states to lead the way in crafting regulations that ensure AI’s benefits are realised without compromising the planet’s future.
