Impact Engine Framework is an Incubation project from the Open Source Working Group in the Green Software Foundation.
IEF is a framework to Model, Measure, siMulate and Monitor the environmental impacts of software
Modern applications are composed of many smaller pieces of software (components) running on many different environments, for example, private cloud, public cloud, bare-metal, virtualized, containerized, mobile, laptops, and desktops.
Every environment requires a different model of measurement, and there is no single solution you can use to calculate the environmental impacts for all components on all environments.
The friction to measuring software emissions isn't that we need to know how, it's that we run software on many things and each thing has several different ways to measure.
