The Korea Occupational Safety and Health Agency conducted a ‘Mailbox Cleanup Campaign’ to participate in environmental protection by deleting unnecessary emails.


Emails consume electricity during the process of storing digital information, generating digital carbon.


Digital carbon refers to the carbon emissions produced during the use of digital devices. Typical examples include carbon dioxide generated from the power consumption of network equipment used for data transmission and the electricity used for cooling data centers that store data.


Generally, deleting 1GB of unnecessary emails reduces carbon dioxide emissions by approximately 14.9 kg and decreases server usage capacity, resulting in electricity savings.
