Why bankrupt only the small coal and oil producers? Seems a little "pro-big corporation" to me.
Well she didn't say, but I suspect it's because the big names are easily co-opted toward "progressive" agenda ideas. BP, Shell, etc, are all in on the "energy transition" and "renewables." Smaller companies are not so easily fooled.
But the bigger point, to me, is about government taking as an acceptable objective the bankruptcy of legally-operating enterprises, whether large or small.
