Located in Croissy-Beaubourg, France, the Pierre Chevet sports hall is made from hempcrete (a mix of hemp, lime, and water) blocks and has become the world’s very first carbon-negative public building.
According to Darshil Shah of Cambridge's Centre for Natural Material Innovation, hemp may capture carbon twice as well as trees. Furthermore, as Hemp Industry Daily pointed out, research has proved that hemp is one of the best carbon dioxide-to-biomass converters. It's even more efficient than planting trees. Per hectare of growing, industrial hemp absorbs between 8 and 15 tonnes of carbon dioxide. Hemp can reach a height of 13 feet (4 meters) in 90 to 120 days. It grows 100 times faster than an oak tree and is lighter and less expensive than wood.
