The most polluting investor-owned companies on the list are ExxonMobil, Shell, BP and Chevron
Just 100 companies are responsible for more than 70 per cent of global greenhouse gas emissions over the last three decades, new research has revealed.
The Carbon Majors Report, from the Carbon Disclosure Project, found that just 25 of those companies are the source of more than half of greenhouse gas emissions since 1988 – the year the Intergovernmental Panel on Climate Change was established.
The most polluting investor-owned companies on the list are ExxonMobil, Shell, BP and Chevron, while state-backed Saudi Aramco, China’s coal industry and Russia’s Gazprom have been the top three greenhouse gas emitters overall.
China’s coal industry, which is dominated by a collection of state-owned or managed firms, has emitted an estimated 14.3 per cent of the world’s industrial greenhouse gases since 1988. The report takes entities these together, making them by far the biggest contributor to man-made climate change. Saudi Aramco is next on the list, having contributed 4.5 per cent, followed by Gazprom with 3.9 per cent.
