How we calculated this

Calculation methodology

The emissions calculation for a short email, defined as an email containing approximately 5 sentences or less, sent from a laptop to another laptop, is based on the energy consumption of data centers, networks, and end-user devices. This estimate considers the average energy usage and emissions factors for electricity consumption.

74,080 kg ÷ 0.0003 kg = 246,933,333 short emails sent

Our forest captured: 74.08 tonnes CO₂

Emissions per short emails sen: 0.0003 kg CO₂
