The reason this technology may work out well is that human prefer to lay concrete than to plant trees .
One thing is certain human will not stop using cement/concretes , So a cement that capture 3/4 ton of CO2 /per ton of cement more than conventional portland cement has got to be a green winner .
How this will compare with a small tree over its life time i dont know, But most of us humans don't want a tree house as their main residence.
