The Environmental Impact of Email Signatures and Spam
Every email requires energy to store, send, and display, and much of this energy comes from fossil fuels. The larger the email, the greater its carbon footprint. This is a little-known impact that can have a significant impact on the environment.
The Problem with Email Signatures
Many email signatures contain superfluous elements, such as legal notices, company logos, and promotional messages, adding unnecessarily to the quantity of information exchanged. These additional elements can increase the size of an email, resulting in a greater carbon footprint.
The Study
Joshua Pearce, professor of information technology and innovation at Western University, has examined this impact in a study published in the journal Sustainable Futures. He looked at two recent additions to signatures: the stating of gender pronouns and land acknowledgements. Although symbolically important, this information slightly increases the size of emails and, consequently, their carbon footprint.
The Consequences
His study reveals that in Canada, where around 15% of professionals add their pronouns to their signature, this addition could generate enough emissions to be responsible for one premature death a year. This is a striking figure, given that 1,000 tonnes of carbon dioxide emitted can cause the premature death of one person.
Solutions
Clearly, reducing the size of your emails could be a simple but effective gesture to limit your digital footprint. Solutions do exist. Rather than systematically including signatures, a simple link to a dedicated page could suffice. A more radical alternative could be to do away with signatures altogether. After all, emails already contain the sender’s details in the header, and nobody (or almost nobody) signs their SMS messages.
The Problem with Spam
In addition to signatures, there’s another scourge that adds to our carbon footprint: spam. Spam accounts for more than half of all emails sent, and even though it often remains unread, its storage and forwarding generate a sizable environmental footprint. There are measures in place to address this, such as taxes on emails or opt-in systems, but they do little to curb the phenomenon.
Rethinking Habits
At a time when digital technology is taking on an ever-greater role in people’s lives, it’s becoming essential to rethink habits. Reducing the size of your emails, avoiding superfluous messages, and streamlining your signatures are all simple gestures which, on a large scale, can have a real impact.
Conclusion
In the fight against climate change, every action counts… even clicking on "delete signature." By being mindful of the environmental impact of email signatures and spam, we can all play a role in reducing our digital footprint.
