According to your source, the top 1% emit 50 tonnes of CO2/capita/yr. The top 0.1% emit 200 tonnes of CO2/capita/yr. That is still an insane increase the wealthier one becomes.
Not saying that one should not try to limit their emissions (we definitely should stop buying stuff from amazon/big companies, if not to limit emissions, at least to break their monopolies), but there is definitely some low hanging fruit in that top percentage (e.g. having 800 people limit emissions is going to be harder when you have the same effect by just limiting the 8 at the top).
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)
