These accounting of subsidies almost always omit the bulk as not accounted in euros. The disaster liability subsidy, and the decommissioning subsidy are rarely so much as mentioned.
They don't account for theoretical subsidies of money, as then there would be more money in subsidies than there would be money. The theoretical subsidies that currently goes into fossil fuel to pay for global warming is reaching the point of infinitive money in the case that global warming goes beyond the tipping point. Theoretical subsidies are fun thought experiments but they aren't very valuable, as is infinitive money.
The report do account for decommissioning subsidy if there is actually government money going into the hands of power plants owners.
