How much CO2 does sending an email produce?

This is one of the issues that Stefano Forti, Researcher and Assistant Professor at the University of Pisa, discussed with us during the Red Symposium, an event organized by Extra Red every month.

The environmental theme is extremely relevant, and realizing that every email we send produces the equivalent of 20 g of CO2 is truly impressive (just thinking about all the emails I receive and send every day makes me sweat!).

We talked about sustainability, software engineering (specifically the GREENSOFT model), examined a case study, and looked at the regulatory framework.

A fascinating debate emerged, and among the various topics that came up, there are some very interesting aspects worth reflecting on:

• Quality is always a valuable asset: saving resources, optimizing software and processes, doing a better job than yesterday in the "usual" work pays off in every sense, not just economically but also environmentally.
• Act where you have control: we all have the power in our hands, and even if it's often small, it doesn't mean it has no effect. Similarly, we can act on our actions and not on others: let's focus on what we can do and do it!
• The issue is extremely complex: we live in a large and interconnected world, where dynamics are intricate, and the actions of some can have consequences for others. What may seem like a way to do good can turn into an authentic tragedy for others (is it beneficial to get a new, more efficient and less environmentally impactful computer if the old one is discarded in a hazardous waste landfill in a poor and exploited country? Have we as humanity gained or lost?).

There are no simple solutions to complex problems, and certainly what we can do is set a direction and do our best, gaining awareness and evaluating all the consequences of our actions.
