Obesity is a crisis in itself, however, when some 100 companies have produced 71% of global emissions[0], it's not individuals, who in total would potentially reduce CO2 emissions by 0.2%, that are causing this. It's these companies.
i.e. if a Norwegian oil company pulls oil out of the ground and I buy it from them to put in a private jet that flies around in circles while I party in it, rather than the CO2 emissions being attributed to me, they are attributed to the Norwegian oil company that pulled it from the ground.
Obviously, this is a completely useless study which only exists to shift blame. There is nothing insightful about it.
(And most of the firms listed are government run, Saudi Aramco, China Coal, etc...)
