From the summary: "The four major oil companies the study focuses on account for more than 10% of global carbon emissions since 1965, the researchers said.." As with the title so with this little paragraph, the narrative behind them is perfidious, dishonest aimed to arouse emotions and prejudices. It is simply vulgar to think within boarders outlined by such lazy argument. If you are so concerned (authors) than do it right (with your wallet). Immediately stop using any and all oil based products and services rendered using oil or its derivative, not only used in transportation of raw or derived parts in any machine in the supply chain. Im puzzled how can a modern educated men produce or consume without outrage these arguments grounded upon such a childish complex of fallacies that we must form societal and political taboos in order that they cannot be argued away by even the most infantile of reasoning. *A serious debate upon transition from fossil fuels and products is beyond the scope, which has dimension of physics, geopolitics, culture, ecology, etc. It definitely does not being with a blame game of such a volume of stupidity as to shift it onto a private-state owned businesses.
