Comparing users to MAU seems disingenuous. The fediverse has ~12 million users, according to fedidb and around 1.1 million active ones.

Most of them on Mastodon.

It will take some time but I will answer with sources. Can you post the source used in the map i have never been able to find anything that came close.

This map underrepresents emissions from NPPs. The emissions that are assumed for nuclear are lower than everything you find in literature and are 1/5th to 1/10th of what reputable sources state. That being said, this map is otherwise a great resource and i like it very much.

“Enlightened” centrism is not the answer…

Yes for Sulfur derivates and nitrous oxigens but no for CO2. The biggest contributord to CO2 emissions are electricity production and traffic.
