There's no shortage of tips and how-tos for a more sustainable lifestyle; the internet is (thankfully) full of guides and checklists on avoiding plastic, saving electricity, saving water, and on and on. That's why here we only share with you the tips that we also implement ourselves, that come easily to us or that gave us a little " Aha " moment.

Do you have a tip for us that we should publish here? Then drop us a line!

CO2 in office and home office - Data as an energy guzzler

Whether home office or office, working behind a computer costs an unbelievable amount of energy. A small calculation experiment to clarify: How much CO2 is emitted by sending and reading an email is not entirely clear, but various sources assume 1-10 grams of CO2 per email. So let's take the average of 5 grams per mail. The new CO2 limit for cars is 95 grams per kilometer since 2021 . So if we send 20 emails, we have driven 1 kilometer by car in terms of CO2. Additionally, we should consider the storage and multiple backups of this one email. This is how you can reduce your footprint in the office:

Delete emails and write fewer of them

Do we really need that quick "OK"? Do I really need to CC all five of my colleagues? If we think about the necessity of emails for a moment, we can already save quite a bit of CO2. And for example, take time once a week to delete the emails you don't need anymore. Or get into the habit of deleting them immediately after reading or working with them. Every saved email costs data in the data centers. There is a lot of potential to save! And if you can't part with some mails, maybe you could save them locally?

Unsubscribe from newsletters

How many newsletters do you receive that you regularly click off? That's hundreds of unnecessary emails that are sent. Unsubscribing is not only worthwhile for more order in your inbox, but is also good for the environment. This can also be transferred to private life, where (at least in our experience) even more unnecessary newsletters are circulating through inboxes. But beware of spam mails: Under no circumstances should you reply to them or click the "unsubscribe" link! Better block the sender. More information here.

Deactivate signature in reply mails

Every character sent creates data. The less of it you send, the better! In addition, many signatures also contain images, which significantly increases the amount of data. And from the second email on, the signature no longer provides any real added value, as it is included in the email history.

Turn off the monitor during breaks and at the end of the day

A monitor on standby draws a lot of power. So always remember to turn it off completely when you are away from your desk for a while. And here’s an analogue tip for the forgetful among us: A small sticky note at the monitor's edge can help. 🙂

Don't become a data hog

Maybe it makes sense to keep different versions of a document during the course of a project. But at the latest after completion you can delete a lot of data. Even if they are stored locally, maybe you make a regular cloud backup? This unnecessary data is already consuming a lot of energy. It's a similar story with media. Here, a unified media database is worthwhile. This prevents a picture from being stored multiple times in different folders. So: Get to the folders and clean out your data garbage!

Avoid screensaver

The most beautiful vacation pictures, fancy shapes that twist and turn. Looks nice as a screensaver, but consumes unnecessary power. Lock your screen even during short absences (indispensable for data protection reasons alone) and then leave it black.
