Tips on open source, environmentally friendly cloud storage

[mahesh]

Hello! I'm all in favor of open source and try to use it whenever possible. I'm also concerned about the environment and because of the current crisis with rising co2-levels try to lessen my dito footprint in the digital world. This my question; I've been using dropbox for a long time, but when I started to do a little research on how different tech companies handled the question of the climate, I found out that dropbox doesn't even have a policy on the issue. So I migrated my data and am now on Google drive, since they have a comparably good policy on reducing emissions etc. However, if there is an alternative that is about open source AND have a strong commitment to the environment (for example by only using renewable energy to power their servers), I would definitely go for that option instead. So far, I haven't been able to find anything along these lines, does anyone in here have any tips to provide?
