A specification that describes how to calculate a carbon intensity for software applications.
Created and managed by the Standards Working Group in the greensoftware.foundation.
This document, the Software Carbon Intensity technical specification, describes how to calculate the carbon intensity of a software application. It describes the methodology of calculating the total carbon emissions and the selection criteria to turn the total into a rate that can be used to achieve real-world, physical emissions reductions, also known as abatement.
Electricity has a carbon intensity depending on where and when it is consumed. An intensity is a rate. It has a numerator and a denominator. A rate provides you with helpful information when considering the growth of a software product. This specification describes the carbon intensity of a software application or service.
