SustAIn

A dedicated Chrome extension designed to raise awareness about sustainability when using AI technologies

🌱 SustAIn: Building a Sustainable Future for AI-Powered Web Experiences As artificial intelligence becomes increasingly integrated into our daily online experiences, a critical aspect remains hidden from the average user — the environmental cost of AI interactions. Each time we generate an AI response, run a model, or engage with AI-driven tools, we trigger compute-heavy operations that require substantial electricity, often sourced from carbon-intensive energy grids. This invisible footprint adds up significantly over time and across users, contributing to global carbon emissions in ways that remain unmonitored and unaddressed. SustAIn (short for Sustainable AI) is a pioneering Chrome extension designed to bring sustainability transparency to AI usage on the web. It is the first of its kind to estimate and display real-time environmental metrics — such as carbon emissions and energy efficiency — directly within the browser, precisely at the point where users interact with AI-powered services. Whether you're chatting with a generative model, using an AI content generator, or analyzing data with smart tools, SustAIn helps users visualize the environmental impact of each action and encourages more mindful digital behavior. Unlike existing browser add-ons focused solely on privacy, performance, or user experience, SustAIn introduces an entirely new category: Digital Sustainability Metrics. With the world moving toward carbon neutrality and green technology, SustAIn fills a critical gap by offering users and developers an easy, transparent way to track and reduce their AI-related carbon footprint. How It Works SustAIn operates silently in the background until it detects interactions with AI services. Once a query is submitted and the action icon is pressed, the extension triggers a lightweight backend process involving a custom-trained machine learning model hosted on Google Cloud Vertex AI. This model classifies the type of AI interaction, estimates the compute complexity, and, using real-time APIs for electricity data, geolocation, and data center power usage effectiveness (PUE), delivers accurate environmental metrics in milliseconds. The extension overlays these metrics non-intrusively on the page, ensuring the user experience is not disrupted. Users can quickly learn how much electricity was consumed, the estimated carbon emitted, and the relative efficiency of the AI service they're using. Why It Matters SustAIn isn’t just a Chrome extension — it’s a step toward accountable innovation. It empowers users to ask important questions: What is the environmental cost of my online behavior? Is this AI service optimized for power efficiency? Can I reduce emissions by choosing when and where I use AI tools? By answering these questions transparently, SustAIn drives digital sustainability from the ground up. It also supports researchers, developers, and cloud architects by offering a companion React component library (still under development). This allows sustainability metrics to be deeply embedded into enterprise AI platforms, dashboards, or research tools — helping teams measure and optimize the carbon footprint of their AI models at scale. Built with Responsibility SustAIn is developed with a strong ethical foundation. We chose not to rely on large foundation models or commercial LLMs within our stack. Instead, we built and trained a small-scale classifier model to ensure minimal compute usage and lower emissions from the extension itself. This principle of "building sustainably to measure sustainability" is core to our project ethos. All data is processed with privacy in mind — no personal data is collected, stored, or shared. The APIs used are purposefully lightweight and focused only on environmental context like IP region, electricity grid data, and timestamp-based efficiency metrics. Who Can Benefit Everyday users of generative AI tools can become more aware of their environmental impact. Developers and startups can integrate our open React components to inform their users and build greener applications. Researchers and data scientists can gather transparent benchmarks to evaluate AI system efficiency. Sustainability teams within tech companies can use the insights to optimize cloud region selection and model deployment strategies. Looking Ahead SustAIn is not just a browser add-on; it’s a movement to make AI usage visible, accountable, and aligned with our planet’s future. Our roadmap includes mobile integration, deep partnerships with cloud platforms, and support for enterprise-level emissions tracking. As AI continues to integrate into everyday web experiences, publishing SustAIn on the Chrome Web Store offers a unique opportunity to make environmental awareness a default feature of digital life. By making sustainability metrics easily accessible to millions of users, SustAIn transforms passive AI interactions into informed, responsible choices. With your support, this extension can spark a shift toward greener online habits, empower developers to build more efficient AI tools, and establish Chrome as a platform that champions transparency and environmental accountability.
