Making Real Zero Carbon Buildings with Carbon Storing Materials (What is Embodied Carbon?)

Interesting video on carbon sequestering. Do you think this video is accurate?



Overly simplistic for a number of reasons, but for one example, you are going to have to go out and grow tress for 30 years first, before you build, in order to take any additional carbon out of the system.


Trees sequester carbon while they are growing, and younger trees sequester more carbon than do older mature trees. Perennial plants are the key while annual crops are not as they release their sequestration quickly into the atmosphere. One must distinguish plant categories of C3 and C4 plants to understand the amount of sequestration or as the video presumes, carbon storage. But it all comes down to this; CO2 is not the main driver of climate nor is methane and keeping a balance in the ecosystem of the carbon cycle is the goal. Current CO2 concentrations have only helped biomass production increases, however over logging and the deforestation of the world’s forest may upset this cycle to a point where it may someday become an issue. At 415 ppmv of atmospheric carbon dioxide, it is not an issue.
