"Well...
I dont think that it is quite as simple as that.'Biofuels' such as ethanol, wood etc... all 'consume' CO2 in their lifetime, reducing the overall emissions."
And every bit of it is released- and then some when the bio product is processed and burned.
The real truth of the matter is man made co2 is only a tiny part of a fraction of the co2 produced and released by good ol' mother earth.
"Global warming" caused by co2, man made co2 at that, is a joke. Even is man stopped burning all fuels, stopped any and all activities which produced co2, the co2 levels would not be reduced by even 1%. It would be something like 1/10 of 1%.
Co2 is not a pollutant, it's a natural normal and needed element that supports all life on earth, Everything would die without it. Increased co2 just makes things grow better, which in turn reduces co2 over time. Co2 levels rise following global warming (which was in the 30's not now) Global warming and coolingf is simply a natural thing, caused by solar activity. The last "global warming" spell was in the 30's, we are still coming out of a mini ice age which began around 1400, and we still aren't as warm as we were at the time Christ walked the earth.
We still aren't as warm as we were 2000 or so years before that, when elephants, rhino's, tigers, hippo's, etc were abundant withinin the artic circle, living on lush green tropical forage which we see emerging from the ice.
Global warming is a money scam.
Still, that doesn't negate the need for cleaner and renuable energy.
