Send an e-mail quickly and save paper as well: This is how environmental protection works in the office today!
Advanced climate rescuers even provide e-mails with the note "For the sake of environmental protection, check whether it is really necessary to print out this e-mail".
More radical minds even choose the less subtle “think before you print” hint.
There's no question about it: nowadays printing is at least as frowned upon as leaving a combustion engine running at the level crossing when the barrier is down.
And rightly so, of course: both a running engine and a printer pollute the environment and consume resources.
But true environmentalists go much further: They try, if possible, to only write e-mails in emergencies.
Because environmental organizations point out that sending e-mails also kills valuable reserves - in the form of energy, for example, which is required for the production and operation of the devices and the corresponding infrastructure.
Anyone who is aware of this can only get dizzy with the daily garbage, sorry, mail volume in offices around the world.
For example, a study commissioned by the British energy supplier Ovo came to the conclusion that around 16,000 tons of CO2 could be saved each year if every adult islander did not send one e-mail a day (like a pleasantry phrase) - that would correspond to more than 80,000 flights from London to Madrid.
Not only a high volume of mail is bad for the (work) climate.
An overflowing mailbox and the associated long storage times for emails also consume a lot of energy.
In a study commissioned by the energy company Eon, RWTH Aachen University estimates that by 2030, servers and data centers alone will account for 13 percent of the world's electricity requirements.
Note: real climate protectors think before they type.
