Green investment hit a milestone in 2022: The world put as much money into replacing fossil fuels as it put into producing them, with clean energy investments jumping 31% from 2021 to top $1 trillion for the first time. Of course, it's not job done. Annual investments into decarbonizing the economy must triple for the rest of this decade. One area that's seen a dramatic expansion in investment lately is carbon capture.
Removing carbon dioxide from the atmosphere sounds like a fantastical solution to the climate crisis. Nevertheless, thanks to human interventions, an estimated 2 billion tons of CO2 are currently drawn down and locked up per year - underground, in tree trunks, within minerals, at the bottom of the ocean.
