Land unsuitable for tree planting could still be used to reduce levels of carbon dioxide in the atmosphere thanks to new research.
Microscopic tubes that suck in carbon dioxide from the air are being developed by chemists, engineers and medical researchers at the University of Edinburgh, with funding from the RCUK Energy Programme, led by the Engineering and Physical Sciences Research Council (EPSRC).
Just one 1m² unit containing the tiny tubes could adsorb (suck in) the same amount of carbon as 10 average trees.
In the future larger versions of the units could be placed alongside places like motorways or on rooftops to make better use of land and spaces in reducing our carbon footprint.
