I was looking at the song lyrics the other day and this line caught my attention (this is from "Comment est ta peine?" by Benjamin Biolay) -
J'ai fait le bilan carbone trois fois
Puis parlé de ta daronne sur un ton
qu'tu n'aimerais pas
Tu ne le sauras jamais car tu ne l'écoutes pas
If I understand correctly, the literal translation of that line in bold is "I calculated my carbon footprint three times" ... but it makes little sense to me at all. Is there possibly any other slang/colloquial meaning of "faire le bilan carbone" that I am unaware of?
Thanks! Merci beaucoup!
