Green Software Foundation's SCI specification becomes an ISO standard

The Green Software Foundation announces that its Software Carbon Intensity (SCI) specification v1.0, which measures software's carbon footprint, is now an ISO standard.

### What changes On 25 April 2024, the Green Software Foundation (GSF) announces that the **Software Carbon Intensity (SCI) specification v1.0** has been approved and published as an ISO standard (referenced by the GSF as ISO/IEC 21031:2024). ISO confirms it as a reliable, fair and comparable protocol to measure and reduce software's carbon footprint. Version 1.1 of the specification is already available, and the GSF offers tools to compute an SCI score, including the Impact Framework. ### Key facts - Status: version 1.0 of the specification is approved and published by ISO. - Method: a carbon-intensity score for software that includes neither neutralization nor offsets. - Intended use: choosing tools, architectures and services with emissions in mind. - Current version: SCI 1.1, with calculation tools such as the Impact Framework. - Steering: Accenture chairs the GSF; WattTime and Accenture co-chair the standards group. ### Why it matters IT departments and services firms receive more and more requests for carbon-footprint indicators, for sustainability reports and for tenders alike. An ISO standard gives a common, comparable basis, rather than methods specific to each provider. It underpins GreenOps practice, which links architecture decisions to emissions, for example the choice of a cloud region or of a run time. ### Takeaway Software now has a standardized measure of its carbon footprint, a support for GreenOps.
