Pulling carbon dioxide out of thin air
Right now, there are machines that can pull CO2 out of the air. It sounds like a perfect solution to global warming, but as the FT’s Leslie Hook explains, the process is a complex one. It’s also far more expensive than some other methods of sequestering carbon, such as planting trees, although companies are working hard to bring costs down.
