    CO2 emissions from the combustion and use of bio-mass, for purposes of controlling the global warming problem caused by atmospheric carbon dioxide and other greenhouse gases.

    Starting next year, neither EPA nor state air pollution control authorities will consider that an emission source can get credit for root-related carbon sequestration when the source burns or processes wood or other biomass fuels.

    Nothing the diarist has presented is a serious and quantified discussion that addresses the amount of CO2e emissions per unit of MWH of heat input or per MWH of electrical generation output showing such data for biocoal as compared to either Eastern or Western coal.   Any such consideration addressing bio-coal must address the emissions associated with bio-coal preparation, which the diarist does not address.

    Primary control of land management techniques and biomass harvesting techniques will always lie with the operator collecting the biomass.   This means that the most economical method of production of biomass will be used.   That means that whole tree harvest of mature trees not valued for other wood purposes will be the predominant wood production approach, particularly in areas with nearby public forests lands.

    See, for example, this dust-up:

      ... the material that is being combusted, and keep taking your idea off the important thing, which is how much CO2 is in the air.

      Even in the carbon-positive case, you are comparing burning a ton of carbon in the form of mineral coal for a net addition of a ton and a few pounds of CO2, to burning a ton of biomass for the net addition of a few points of CO2, with the ton of fuel itself consisting entirely of carbon recycled from the atmosphere.
