Carbon Footprint from Manufacturing a Network Switch and how to Reduce It?

In 2022, Dell'Oro Group reported that full-year shipments of alone 200 Gbps and 400 Gbps ports reached almost 20 million. That number is expected to rise in years to come. The production of an average switch is estimated to emit approximately 448 kg of CO₂ equivalent, with a standard deviation of 67 kg. Thus, the total annual carbon footprint for those two types of switches is immense.
