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 how to design, develop, and deploy software applications. This specification describes the carbon intensity of a software application or service.
