I always see this in email footers:
"Save paper, consider the environment, do you really need to print this email?"
It got me thinking. Adding this surely has some cost to the planet, eg.:
- Extra bytes to shuffle over the network
- More battery drain on mobiles syncing emails
- Increased data storage required by mail servers
Do you think the added cost to the planet is greater than the resources saved by the few that actually choose not to print the email solely because they read the footer message?
UPDATE: see my comments to Joe's answer below for a killer added cost that'll probably kill the planet.
