Sustainable email is an email service that lowers the environmental impact of digital communications. One effective way of doing this is to reduce carbon emissions by using energy-efficient email servers.
The average carbon footprint of an email of an email is 0.3g CO2e, which includes the IT infrastructure used to write, send and receive, and store the email. So, if you only send an occasional email, it does not have a major environmental impact. If you send hundreds of emails per week, however, you can consider reducing your carbon footprint by cutting down on unnecessary email sending and storage – for example by unsubscribing from mailing lists and newsletters you no longer read. In addition, deleting emails you no longer need can reduce the total energy used for email storage – which is why you might have seen the recommendation to “delete email - save the environment.” It is also helpful to choose an email provider whose data centers use green electricity and energy-efficient servers, like mail.com.
Emails have an environmental impact due to the energy needed to produce, send, and receive them. After all, you need an electronic device to access your emails, and emails can only be stored and transmitted using servers that need energy to run. However, due to the vehicles used in the delivery chain, sending a letter by conventional mail generates much higher carbon emissions than email. Emails also have the advantage of reducing paper waste – as long as we follow the reminder to “Think before you print”
