Not only that, but even then the 100 companies thing is complete BS. That's a measure of consolidation of energy companies, nothing more. If they all merged into a single gigantic hyper-corporation, it wouldn't change emissions. If they split into a million companies, all with 1/10000 the market share of the 100, again, the same.

The statistic is completely meaningless in the context of emissions. The only relevant statistics are total emissions. The atmosphere doesn't count a carbon atom differently by the market cap of the company that dig it up. It doesn't even count them differently if a person emits a tonne or 1000 people emit 1kg each.
