Can someone explain why we need satelites to estimate the CO2 emmissions of a power plant burning coal? Shouldn't it be a pretty trivial and accurate calculation to get that number either from the weight of the coal that you burn or by the megawatt hours you generate?

This is the place for discussing the potential collapse of modern civilization and the environment.
Collapse, in this context, refers to the significant loss of an established level or complexity towards a much simpler state. It can occur differently within many areas, orderly or chaotically, and be willing or unwilling. It does not necessarily imply human extinction or a singular, global event. Although, the longer the duration, the more it resembles a ‘decline’ instead of collapse.

MODERATORS
Yes, but that relies on reporting by the power plants themselves. Obviously that's not the most accurate thing.
Satellites offer an independent way to measure CO2 emissions not just from power plants but from all sources, all over the planet. So in that way it makes sense.
There are other ways to measure and those should be done as well, that way the data can be validated.
