Artificial Intelligence (AI) & Environmental, Social, and Governance (ESG)
Artificial Intelligence (AI) has rapidly emerged as a transformative technology, revolutionizing various industries with its capabilities. From enhancing automation to improving decision-making processes, AI offers immense potential for organizations to increase efficiency and productivity. However, the widespread adoption of AI comes with environmental consequences, particularly in terms of its carbon footprint. Recent studies have shed light on the significant impact of AI on the environment, especially concerning the use of fresh water to cool AI servers. In this article, we will explore how the use of AI is increasing the carbon footprint of organizations and delve into the specific issue of water consumption.
The Carbon Footprint of AI - AI technologies rely heavily on computational power, necessitating substantial energy consumption. The training and inference processes of AI models demand vast amounts of computational resources, including electricity to power the servers and cooling systems. As a result, data centers housing AI infrastructure contribute to a considerable carbon footprint.
According to a report by OpenAI in 2019, training a large-scale AI model could emit more than 284 tons of carbon dioxide equivalent (CO2e), which is roughly equivalent to the lifetime emissions of five average U.S. cars. This estimation includes the energy consumed during the model's development, training, and subsequent use. As organizations increasingly deploy AI applications, these emissions can accumulate and have a substantial environmental impact.
Water Consumption for Cooling AI Servers Apart from the energy-intensive nature of AI, the issue of water consumption is also a growing concern. Data centers housing AI servers require efficient cooling mechanisms to prevent overheating. Traditionally, water has been the primary coolant in many data centers, where it absorbs heat and is then circulated through the cooling systems to maintain optimal operating temperatures.
A study published in the journal Nature in 2019 highlighted the alarming water usage by data centers. It estimated that the global data center industry consumes approximately 200 billion liters of water annually, equivalent to the water consumption of around 820,000 Olympic-sized swimming pools. The report also predicted that water usage by data centers could triple within the next decade if current trends continue.
AI-specific servers often require even more cooling due to their higher computational demands. As organizations expand their AI infrastructure to accommodate larger models and more complex tasks, the water consumption for cooling purposes is expected to rise accordingly.
Mitigating the Environmental Impact While the use of AI contributes to the carbon footprint of an organizations, it is important to note that AI can also be utilized to address and mitigate environmental challenges. AI-driven optimization algorithms, for instance, can optimize energy consumption and reduce waste in various industries. AI can also be applied to develop innovative solutions for renewable energy generation, smart grids, and sustainable resource management.

To minimize the environmental impact of AI, organizations can adopt several strategies. First, they can prioritize energy-efficient hardware and cooling systems to reduce overall energy consumption. Additionally, the adoption of renewable energy sources, such as solar or wind power, can significantly reduce the carbon footprint associated with AI operations.
Moreover, an organizations can explore alternative cooling technologies that require less water or employ water recycling techniques to minimize fresh water consumption. Advances in liquid cooling systems, which use non-conductive fluids, show promise in reducing water usage while maintaining optimal server temperatures.
