To my knowledge, none of the proposed "green" fuels (ethanol, methanol) reduce or remove the emmission of CO2 as a by-product of their use. They <b>might</b> have a higher "unit energy per carbon unit" output. From the figures I have seen that return might be marginal at best - 5% or so. How does "bio-mass fuel" (and yes I know what it is) make any great difference - other than by reducing the use of <b>mineral</b> oil? That difference is not, I suggest, making any great difference to carbon emission. It does make a <b>strategic</b> difference to fuel availability but that does nothing for climate change.
