TLDR: Meta has unveiled a groundbreaking AI-driven methodology to enhance the accuracy and coverage of Scope 3 emissions estimates across its vast IT hardware supply chain. This initiative, presented at the 2025 Open Compute Project (OCP) summit, combines machine learning and generative AI to standardize component classification, infer missing product carbon footprint (PCF) data, and drive industry-wide sustainable practices, aligning with Meta’s goal of achieving net-zero emissions by 2030.
Meta is making significant strides in its commitment to sustainability, announcing a sophisticated AI-based approach designed to standardize operations and substantially reduce carbon emissions within its IT hardware supply chain. This innovative methodology, detailed at the 2025 Open Compute Project (OCP) regional EMEA summit, is a critical component of Meta’s ambitious roadmap to achieve net-zero emissions across its value chain by 2030.
The core of Meta’s strategy involves a hybrid AI pipeline that leverages both machine learning (ML) and generative AI (GenAI) models. The primary objective is to improve the quality and consistency of Scope 3 emissions estimates, which are notoriously challenging to quantify due to complex supply chains and often inconsistent data from suppliers.
Meta’s engineers have developed a system that uses machine learning to estimate Product Carbon Footprints (PCFs) by identifying components with similar specifications. This is crucial because conducting a full PCF for every single component can be a time-consuming process, often taking months. By identifying ‘proxy components’ through natural language processing (NLP) algorithms, Meta can apply high-quality PCF data to similar parts, ensuring consistency and improving traceability of carbon footprint estimates across its hundreds of millions of components.
In parallel, a generative AI model plays a pivotal role in classifying hardware into a shared, standardized taxonomy for Scope 3 reporting. This addresses a significant challenge: the inconsistent naming and categorization of components across different suppliers. By employing GenAI to interpret diverse part descriptions and unify them under a common schema, Meta can achieve more consistent PCF assignments and reduce redundant disclosures for similar hardware. The company specifically utilizes large language models (LLMs), including Llama 3.1, for extracting and processing information from heterogeneous data sources, understanding potential component groupings for taxonomy creation, and strictly classifying components based on text strings. This LLM-driven approach significantly reduces the training time typically required for traditional AI models.
The methodology allows for a granular analysis of emissions, from individual screws to entire server rack assemblies, enabling Meta to pinpoint high-impact areas for emissions reduction interventions. For instance, if a component is identified with a disproportionately high carbon footprint, Meta can explore alternative materials, manufacturing processes, or even extend the useful life of components through testing and augmentation.
Meta is not only implementing this internally but is also committed to open-sourcing its taxonomy and methodology for server rack emissions accounting, as well as the GenAI-powered taxonomy builder. This collaborative effort with the OCP PCR workstream aims to encourage industry-wide adoption of common standards for measuring and reporting carbon emissions, fostering more sustainable manufacturing practices across the entire IT hardware ecosystem.

This initiative reflects a broader industry trend where AI techniques are increasingly applied not just to measure environmental impact, but to actively manage and reduce it across digital infrastructure. Other tech giants like Google and Microsoft are also integrating AI into their sustainability strategies, with Google reporting a 12% drop in data center emissions in 2024 due to AI-driven optimizations, and Microsoft applying machine learning to areas like power forecasting and grid-aware workload scheduling in Azure data centers.
