Green Software

Info

Green software is part of Sustainable Computing / Green IT.

Green software can be divided into multiple aspects:

Energy-efficient → consume the least amount of electricity possible
Resource-efficient → use the least amount of resources possible (including embodied carbon)
Carbon-aware → do more when the electricity is cleaner and do less when the electricity is dirtier

Definition

Greening in software aims to reduce the environmental impact caused by the software itself. [...] Green specifications provide a way to indicate a service’s carbon footprint and eventually specify operational constraints to allow more flexibility during service provisioning.

Why does it matter?

Software engineers social and environmental responsibility

How to assess the footprint?

Life Cycle Assessment of Software

How to optimize?
