Convert network energy use into annual CO2e emissions, per-device intensity and the trees needed to offset it.
Network emissions are entirely a function of energy drawn and how that energy was generated, so PUE and grid intensity matter as much as the equipment itself. The renewable share reduces the reported figure under market-based accounting. Sustainability reporting increasingly covers IT infrastructure, and the per-device intensity is the metric that justifies replacing older hardware on carbon grounds rather than performance alone.
Network Carbon Emission
emissions = IT kW × PUE × 8760 h × grid intensity × (1 − renewable share).
