Green IT and Software Carbon Intensity
Green IT defines standards for reducing the environmental footprint of information technology. A key technical standard is Software Carbon Intensity (SCI), which measures the CO₂ emissions of software.
Core Concept
Sustainability is achieved through efficient programming (green coding), optimised hardware utilisation (right-sizing), and sourcing energy from renewable sources in data centres.
Relevance
- SCI Metric: Calculation of emissions per functional unit (e.g. per API call or user session).
- Circular Economy: Standards for the procurement and recycling of hardware.
- Energy Efficiency Labels: Use of certified cloud regions with low PUE values.
