Review the videos and photos on your devices

We are used to taking several photos and videos of each situation in order to capture just the right moment. Now it is wise to delete those double frames and keep the most perfect one.
Did you know that photos and videos taken from one event can generate as much CO2 as driving a car for twenty kilometers?

Unsubscribe from unnecessary newsletters

Did you know that every e-mail that reaches your inbox generates at least four grams of CO2?
Go to your e-mail box and keep an eye on which newsletters you have subscribed to and which you don't even open. Don't just delete these emails, but also unsubscribe from them.

Review your old accounts and mailboxes that you no longer use

You might actually be surprised how much useless stuff you find there that you don't need anymore.
Arbitrary files can also be found in all kinds of cloud services that provide free space, such as Google Drive and Dropbox. Check what's there and delete anything that could pose a danger in the wrong hands.

Delete programs and applications that you no longer need

There are certainly plenty of programs on your computer and phone that you no longer use.
If you delete them, the devices will become faster and their life will be longer.

Check the Downloads folder

Many files that we don't really need can end up in this folder, but still are saved to our computer when we open them in our e-mail box.
Delete these files and then empty your device's trash bin.
