Carbon footprint of the main type of email
Your Digital Footprint Is Bigger Than You Think
We often think of climate change in terms of factories and cars, but the tools we use every day emails, video calls, and instant messages are also quietly contributing to the problem. The energy required to power data centers, servers, and networks for our digital lives creates a significant amount of carbon emissions. Digital pollution is invisible, but it’s very real.
The Carbon Truth About Your Communication
The carbon cost of our daily communication is a clear indicator of this hidden impact:
- A one-hour video conference call can produce up to 1000g of CO₂.
- A single email with an attachment can generate as much as 26g of CO₂.
- Even a simple message on platforms like Slack or Teams produces around 0.055g of CO₂.
- An SMS, in contrast, has a minimal footprint of just 0.00215g of CO₂.
When you multiply these numbers by the millions of messages and calls that happen every day, the emissions add up to megatons of carbon.
Small Changes for a Big Impact
The good news is that we have the power to reduce our digital footprint with a few simple changes:
- Turn off your video during calls when it’s not essential.
- Avoid sending unnecessary emails, like those one-word “thank you” replies.
- Declutter your inbox by deleting old emails you no longer need.
- Use chat or SMS for quick, short messages instead of email.
These small, sustainable swaps can make a meaningful difference. By being more intentional about how we communicate, we can start to clean up our digital world, one pixel at a time.
