How much CO₂ does your email activity emit?

The internet now makes up 4% of carbon footprint, more than the airline industry — and is predicted to even double by 2025.

Sending and receiving an email gives off 0.3g of CO₂ emissions; an email with attachments emits 50g of CO₂. If the average worker sends out 121 emails each day, that is equivalent to 1652g of CO₂ emissions! A typical business user’s email habits create 135kg of CO₂ emissions each year— the equivalent of driving 321km in a car!

According to the Carbon Literacy Project, changing your email habits can go a long way in reducing your carbon footprint.

Now, think about all the unopened newsletters you receive each day. Brands send about 1 to 4 emails each week — some, even more. If you get 100 emails a day and half of those are newsletters, you might want to consider unsubscribing from the ones you do not need.

Yahoo believes that sustainability is everyone’s responsibility.

Let’s make that happen together. This Earth Day, by pledging your support to declutter your digital activities, including your emails, you can do your part in reducing your online carbon footprint and help raise awareness on how we can all be part of the digital green solution.

Yahoo commits to amplify your support for our goal to help people be more conscious of their digital carbon footprint and to plant 200 trees — for every 25 pledges to #DeclutterWithYahoo for #YahooEarthDay, 1 tree will be planted in partnership with Treedom — and you can follow its progress from the nursery to the ground on the Yahoo Forest Page.

Treedom is the world’s first platform that allows you to plant a tree from a distance and follow the story of the tree-planting project it belongs to online. Since its foundation in 2010 in Florence - Italy, more than 3 million trees have been planted in Africa, South America, Asia, and Italy.
