MIT Technology Review: Why the world’s biggest CO2-sucking plant would be used to … err, dig up more oil?

A Canadian startup plans to build the largest carbon dioxide removal plant in the world, capable of sucking half a million metric tons of the greenhouse gas out of the air every year. If the project is ultimately built, it will represent a big step forward for direct air capture, a technology that a growing number of studies find could be essential for preventing dangerous levels of global warming. But it comes with a catch.
