I did say removing tax exemptions and subsidies for fossil fuels.
Well, that gets into a new area of debate. Most of the parties which pay subsidies for oil are OPEC countries which have little interest in stopping such payments. In comparison, your average developed world country just isn't kicking that much out in subsidy. Most of the remaining subsidies are of the sort given to similar industries (such as the accelerated depreciation schedule given to resource extract industries, for example). I include the US military-industrial complex in that - which is really a subsidy for defense rent-seekers than oil producers.
Then there are the fantasy numbers attached to the alleged environmental harm of petroleum. Sure, if oil really did have a huge global warming externality attached to it, then yes, you could reasonably consider that akin to subsidy.
I don't consider complaints about petroleum subsidies very serious, when they ignore both that much of the alleged subsidies are either outside the control of the country they reside in or imaginary.
