Well, it depends on the water content of the wood. But assuming the wood contains about 10% water (within the normal range of air-dried wood), a ton of wood, if burned, would produce approximately 1.5 tons Carbon Dioxide, or about 0.4 ton "carbon equivalent", which just means the weight of the carbon that is contained in the carbon dioxide.
Measuring the energy content of woody biomass is somewhat inexact due to the amount of moisture contained in the biomass. A 20% moisture content would contain approx. 6,400 Btu/lb. Bone dry biomass (0% moisture content) has a Btu value of 9,400 Btu/lb. Moisture content greater than 20% reduces the Btu value considerably. If your biomass has the equivalent of 7000 Btu (somewhere between "bone dry" and 20% moisture content), one pound of that material with a 100% conversion rate would produce just over 2kwh of electricity. 100% conversion is unlikely so assume a 50% conversion rate (which is excellent) and the result would be 1 pound of relatively dry biomass would produce 1kwh of electricity. The typical American home consumes about 1000kwh/month. So, powering a typical American home with biomass for one would require 1000lbs. of wood chips per month. The current price of woody biomass varies but $30/ton is a safe estimate. Even if the conversion factor were only 25%, one ton of woody biomass could power your home for a month for $30. How much is your electric bill from the power company? Of course there needs to be a device that converts the woody biomass to electricity.
Biomass energy produces 3% of the worlds energy
CO2
The burning of a wooden stick is a chemical process.
The released gases are carbon dioxide and water vapors; a simple test for CO2 is the absorption in calcium hydroxide.If the burning is not incomplete also carbon monoxide is formed; as impurities - sulfur and nitrogen oxides.
Burning magnesium reacts with co2. As a result white powders of magnesium oxide is produced along with black particle of carbon. 2Mg+Co2=2MgO+C.
CO, CO2, H2O and more comlicated structures.
Wood is better if you have plenty of wood available and can grow more trees while you are burning the old ones. That makes you carbon-neutral, because while burning wood produces CO2, growing wood takes CO2 out of the atmosphere in equal measure.

CO2
Carbon oxydation C + O2-------CO2
Water (H2O) and Carbon dioxide (CO2)
Burning one 20lb tire releases 60lbs of CO2.
44 grams of CO2 (1 mol CO2 from 1 mol C if enough oxygen, air, is available)
2.6 Kg of CO2
[ 34.3(gC3H8) / 44(g/mol C3H8)] * [ 3mol CO2 / 1molC3H8 ] * 44(g/mol CO2) = 103 gram CO2
It's all in the chemistry. CO2, from which the carbon in the wood was derived, is re-released into the atmosphere as the wood burns. (CH2O + H2O) + O2 --combustion--> 2H2O + CO2

Carbohydrates are burning inside. it will form CO2and energy.
