Once again, I would like to clarify. If you look up the definition of the word "subsidy,” basically, I think most people agree that the reference point is the World Trade Organization's definition. This has already been discussed. Starting from that definition of the word "subsidy,” the second step is to apply it more specifically to fossil fuels.

A recording is available from Parliament.
