Introduction #
The Green AI Model is a comprehensive framework intended to guide stakeholders through the AI life cycle. It highlights key influencing factors and their interrelations that need to be considered to enhance the sustainability of AI systems. This model is pivotal in advancing the dual objectives of Green AI: mitigating climate change and minimizing environmental impacts. Green AI achieves this through two principal approaches: “Green by AI” and “Green in AI.”
This model focuses exclusively on the “Green in AI” dimension of sustainability, which aims to make AI itself greener rather than using AI as a tool for broader environmental purposes. It provides structured guidance for reducing the energy consumption, carbon emissions, and resource use associated with AI based software.
This model not only advocates for resource efficiency but also champions the adoption of practices that reduce the environmental footprint of AI operations. This guidance is intended to facilitate the transition of the AI community towards a more sustainable and environmentally friendly future.
Why does this model exist and why is it necessary? #
There are numerous guidelines and methods for measuring and assessing the environmental impact of AI systems. However, these often rely on flawed assumptions or inaccurate data, which can lead to erroneous conclusions. The Green AI Model addresses these issues. It provides a clear and comprehensive list of the factors that influence the sustainability of AI technologies, enabling stakeholders to make more informed and effective decisions. This model facilitates the establishment of consistent standards for evaluating the environmental impact of AI, ensuring that our efforts to make AI “greener” are based on sound scientific principles and are genuinely effective.
How is this model structured? #
This introduction establishes the fundamental distinction between two principal approaches: “Green by AI” focuses on leveraging AI technologies to enhance environmental sustainability. In contrast, “Green in AI” centers on developing AI solutions that inherently consume fewer resources and generate less waste.
Following the introduction, the model details the methods for quantifying the environmental impact of AI systems. It emphasizes the significance of precise measurements in order to comprehend and effectively address this impact of AI technologies. The model covers a range of sources and factors that contribute to the environmental impact of AI technologies.
The central focus of this model is to examine the various factors that influence the sustainability of AI. These are organized into five primary categories: Use Case, Model, Data, Hardware, and Tools. In each category, specific components or practices within AI systems that significantly affect their environmental impact are examined. This includes the energy consumption of data centers, the carbon footprint of hardware production, and the environmental impact of electronic waste disposal.
Furthermore, the model discusses the interplay and interrelationship between these influence factors. It highlights how these elements do not operate in isolation but interact in complex ways that can either amplify or mitigate their individual impacts. This section underscores the necessity of an integrated approach to optimizing ecological sustainability by aligning model complexity with use case requirements, optimizing data characteristics for efficient hardware usage, and selecting appropriate tools that enhance sustainability.
The discussion section addresses potential barriers to adoption, such as technological limitations, economic constraints, and the need for industry-wide standardization to ensure widespread implementation of sustainable practices in AI. Future work will explore real-world applications using the model and address the challenges of implementing the Green AI principles.
How to apply this model? #
This Green AI model can be applied in several ways. First, it can assist in the improvement of both existing and new AI applications. This is achieved by providing a comprehensive overview of the factors that affect environmental impact and demonstrating how to measure this impact. Second, the model serves as a guide for future research. It identifies open questions that need to be addressed in order to develop “truly” Green AI. Finally, it provides non-technical stakeholders, such as policy makers and business leaders, a clear understanding of the current challenges. This supports them to create informed policies and strategies that support the sustainable development of AI.
