Measure AI's Carbon Footprint with Purpose

A standardized specification extending the Software Carbon Intensity methodology to measure the carbon emissions of AI systems throughout their lifecycle.

AI systems have become increasingly resource-intensive, yet there's no consistent way to measure their environmental impact. SCI for AI changes that by providing the first consensus-based standard that makes AI's carbon footprint transparent, comparable, and actionable. Help refine this transformative specification with your feedback and experience as we revolutionize how we build and deploy sustainable AI.

Leading organizations collaborating to standardize AI carbon measurement

What is SCI for AI?

SCI for AI extends the globally adopted Software Carbon Intensity (SCI) ISO specification to address the unique characteristics of artificial intelligence systems. It provides a standardized methodology for calculating carbon emissions rates across the entire AI lifecycle, from data preparation and model training to deployment and inference.

Unlike simple energy metrics or carbon offsets, SCI for AI creates a comprehensive score that incentivizes real emission reductions. By making the true carbon cost of AI transparent and comparable, it transforms sustainability from an abstract goal into a measurable, optimizable metric that drives innovation in efficient AI architectures and influences strategic decisions across industries.

Why SCI for AI Matters

As AI becomes ubiquitous across industries, its environmental footprint grows exponentially, but measurement remains fragmented and inconsistent.

Industry Impact

SCI for AI provides the first consensus-based, standardized approach to measuring AI's environmental impact. This standardization drives innovation in efficient AI architectures, influences procurement decisions, and helps organizations meet sustainability commitments. By revealing the true carbon cost of AI development and deployment, it enables meaningful comparisons between different systems and approaches, transforming how organizations think about AI investments.

Business Benefits

Reduce operational costs through improved computational efficiency and optimized cloud resource consumption

Prepare for future carbon pricing and regulatory requirements with ISO-compatible measurement standards

Gain competitive advantage through transparent sustainability metrics for AI products and services

Make informed trade-offs between model performance and environmental impact with clear, actionable data

Build stakeholder trust through demonstrable commitment to responsible AI development

Environmental Impact

SCI for AI directly addresses the growing carbon footprint of AI systems by providing metrics that incentivize real reductions rather than offsets. The specification reveals hidden impacts in data preparation and training that often dwarf inference costs, encouraging practices like model optimization, efficient architectures, and carbon-aware computing. This comprehensive approach could significantly reduce AI-related emissions by enabling informed choices about when, where, and how AI systems operate.

Understanding AI's Carbon Lifecycle

SCI for AI measures emissions across every stage of AI development and deployment, revealing optimization opportunities throughout the entire lifecycle.

Inception

AI's Hidden Emissions

Traditional approaches often focus solely on inference costs, missing the significant carbon footprint of training and data preparation. SCI for AI provides comprehensive lifecycle coverage, including often-overlooked stages like data engineering and system integration. This holistic view enables organizations to identify and address the true sources of AI emissions.

Insights from the SCI for AI Workshop

In November 2024, representatives from over 20 leading organizations gathered to define the foundation of SCI for AI. This collaborative workshop brought together expertise from ACIS, Accenture, Amadeus, Google, IBM, Microsoft, and many others to establish consensus on methodology, metrics evaluation, and the specification roadmap.

The purpose of this specification is to assist AI practitioners in understanding and reducing the carbon footprint of AI systems. By making informed choices about model design, computational efficiency, and deployment strategies, practitioners can minimize emissions while maintaining performance.
