So yes, in some sense the "fossil fuel industry" is being subsidized, but it's not like they're just receiving $550B in cash from world governments. Many of these countries sell oil domestically far below what the cost of production is. So if you don't subsidize it, their citizens simply wouldn't be able to drive cars or run generators. The oil companies simply can't produce as cheaply as these citizens would need to be able to afford it.
Of course, that would be a great force for incentivizing cheap renewable tech (or bicycles, etc) but the motivation behind said "subsidies" are quality of life and social unrest, and not corporate welfare.
Which is still a petroleum subsidy. They could just give the citizens the equivalent amount of cash and then it wouldn't be.
