That's a measure of consolidation in the energy industry (a lot) and a measure of the proportion of anthropogenic carbon that comes from fossil fuels (also a lot, more than 71%, because there are more than 100 such companies). It wouldn't matter if that 71% of carbon was emitted by a million companies, or by one hyper-giant mega-corporation. Those fossil fuels were getting dug up and burned regardless of the logo on the side of the drilling rig.

Furthermore, as long as fossil fuels exist as a mainstream energy sources, fossil fuel companies, whether a great many small ones, or a few huge ones, will represent a very large proportion of the emissions. You can't change them, that's just literally what they are. You have to either stop them (e.g. make fossil fuel extraction illegal) or change everyone else to remove the market (e.g. encourage use of sustainables, including nuclear, everywhere).
