Also you’re last sentence is quite hostile, BP definitely came up with it to avoid their responsibility and pivot it to other people. The idea might not be ‘bad’ per se, but if you do it so to avoid your own responsibility, it is definitely bad practice (which, again, is why each of us should try to limit our carbon emissions)
Of course. By the same token, individuals trying to avoid their own responsibility by parroting “big oil invented the idea of a carbon footprint” is definitely bad practice.
