"Artificial trees" are a geo-engineering solution that use amine solutions to capture CO2 out of the atmosphere and sequester it underground.
Also known as "air capture" or "carbon scrubbers", the technology is currently in its formative stages but researchers in the US estimate one tree could take as much as 25 times more CO2 out of the atmosphere each year than a normal tree.
A handful of startups are currently looking to bring the technology to market.
