Carrefour font here refers to the font used in the logo of Carrefour, which is a French multinational retailer, also one of the largest hypermarket chains in the world.
The wordmark of Carrefour, redesigned in 2009, seems to be custom designed or using a custom typeface, and for its former wordmark (as shown above), which can still be seen in some store chains, it is probably set in ITC American Typewriter. You can view more details about American Typewriter here.
