Green Software Engineering @uritau 2022
Green software is software that is responsible for emitting fewer greenhouse gases. @uritau 2022
How? Using less physical resources Increasing life expectancy, sharing physical resources and optimizing its usage Using less energy Reducing the wasted energy, improving efficiency or in any way that could help Using energy more intelligently Consuming lower-carbon sources of energy or consuming electricity in a way that helps accelerate the energy transition
“If you can’t measure it, you can’t improve it.” Peter Drucker @uritau 2022
Software Carbon Intensity (SCI) @uritau 2022
The Software Carbon Intensity (SCI) specification gives an approach to developers to measure the carbon impact of their systems. @uritau 2022
SCI Amount of Carbon the software is emitting per Resource (API call, extra user, SaaS, microservice, ML Training system…)
SCI SCI = C * R
SCI ❖ Amount of Carbon the software is emitting per Resource (API call, extra user, SaaS, microservice, ML Training system…) ❖ The amount of Carbon is the sum of Operational emissions plus the embodied emissions
SCI SCI = (O + M) * R
SCI ❖ Amount of Carbon the software is emitting per Resource (API call, extra user, SaaS, microservice, ML Training system…) ❖ The amount of Carbon is the sum of Operational emissions plus the embodied emissions ❖ The operational emission is the location-based marginal carbon emission generated per the energy consumed by a software system
SCI SCI = ((E*I) + M) * R

3 main responsibilities Consumers ● Choose “green” services ● Reduce unnecessary tech usage ● Limit transfer ● Communication good practices ● Long life devices ● Green energy @uritau 2022
3 main roles Consumers “Experts” ● Choose “green” services ● No tech by tech ● Reduce unnecessary tech usage ● Conscious choices ● Evangelize ● Critical opinions ● Limit transfer ● Communication good practices ● Add “SCI” into decisions ● Long life devices ● 5g, crypto, FullHD ● Green energy @uritau 2022
