The Graphic Truth: Petrostates' grim low-carbon future

Reducing carbon emissions is good for the planet and good for your lungs, but there's one group of countries that might not be so keen on green: those that rely heavily on oil and gas exports to run their economies. As the rest of the world gets closer to "Net Zero" in the coming decades, these petrostates will be in big trouble unless they diversify their economies — fast. So, how vulnerable are the world's top oil and gas producers to a low-carbon future? We look at how the treasuries of the 20 most hydrocarbon-dependent nations will fare over the next two decades under what the Carbon Tracker Initiative refers to as a scenario in which global demand for oil and gas will be much lower than today.
