Check out this presentation to learn how a cloud-delivered software-defined wide area network (SD-WAN) is green, lowers carbon footprints and is good for the environment and Earth. Gain a better understanding of how reducing cooling and power requirements in the branch, lower carbon emissions and fewer devices is helping businesses do more for the environment while at the same time saving money.

Cloud-Delivered SD-WAN Eliminates Truck Rolls
Saving 4 Tonnes of CO2 per Year
• Thin branch edge device
• Remote cloud provisioning
• Business-policy based
orchestration
Zero Touch Branches
The average passenger vehicle emits
about 411 grams of CO2 per mile
One truck roll is ~100 mile round trip
100 miles x 411 grams x 100 branches
= 4 Tonnes of CO2 (or 4 carbon credits)
