Carbon Sequestration tax is coming in the future.
Do you know that Straw and other biomass from agriculture and/or horticulture will absorb about 1.78 kg CO2 per kg ?
Agriculture boards absorbs even more CO2 than most forests or trees this need many years to growing up.
At end of life the old ECO-Boards end products can refurbish or reused (the second hand upcoming sales markets ) as raw material for new ECO-Boards and thus the Carbon remains saved > is an example of cradle2cradle .
