The SCI Standard: Providing the Software Emissions Data CSRD Needs
A new white paper from GSF's Software Standards Working Group maps the SCI standard to CSRD's reporting requirements. Learn how to go from software energy data to a CSRD-compliant disclosure, and how SCI complements GHG accounting by adding the granularity needed to measure software impacts.
Designing SCI for Web: What We Agreed and What Comes Next
In autumn 2025, a group of GSF members reached consensus on the design foundation for SCI for Web. Here is what they agreed on, how the AI-assisted process worked, and what's next.
SCI for AI Specification Ratified: Standard for Measuring AI Emissions Across the Lifecycle
We're excited to announce the ratification of the SCI for AI specification, marking a major step in making the carbon footprint of AI systems transparent, comparable, and actionable.
Building Green Software through Standards and Collaboration
CAST, NTT DATA, and UBS share how they are reducing their software emissions and laying a solid foundation for a greener digital future.
Baselining Software Carbon Emissions - A Use Case by UBS
Using the SCI specification, UBS compares two banking applications with regard to their carbon emissions.
How Accenture Implemented the SCI Specification Score to Track Software Emissions
An in depth look at how Accenture implemented the SCI Specification Score to track software emissions.
Carbon-Aware Computing Whitepaper - How UBS succeeded in measuring and reducing carbon emissions of their core risk platform
The first enterprise-scale implementation of carbon-aware computing using the software carbon intensity (SCI) specification and carbon-aware-sdk is capable of avoiding multiple metric tons of CO2eq from entering the atmosphere -- every year.
