Barclays has sunk over US$ 6 billion into ExxonMobil by providing direct lending and through underwriting bonds. ExxonMobil is currently leading the extremely dangerous and destructive ultra deep-sea drilling off the coast of Guyana. The massive oil & gas extraction project would turn the tiny country from a carbon sink with negative emissions to the world’s biggest per capita polluter. An oil spill - and ExxonMobil has a dark history in that regard - would irreversibly damage the entire Caribbean.
