Здравствуйте, Nikе, Вы писали:

Дерево ж почти наполовину состоит из того самого углерода, который оно поглощает из атмосферы фотосинтезом.

CO2 molecule is made of one carbon atom and 2 oxygen atoms. The atomic weight of carbon is 12 and that of oxygen is 16. The molecular weight of CO2 will be 44. This means 12 Kg of carbon on complete combustion will produce 44 Kg. of CO2 or 1 Kg of carbon on complete combustion will produce 3.67 Kg. of CO2.

Wood is heterogeneous and exact amount of carbon in 1 Kg of dry wood will vary depending on the species of wood, age of wood etc. It is reported that 1 Kg of wood contain about 450 to 500 gm of Carbon. This means 1 Kg of wood is holding about 1.65 to 1.80 Kg of CO2. This is how wood or forest act as carbon sink.

... one tonne of wood has absorbed a net 1.7 tonnes of CO2 from the atmosphere, over and above the energy expended in growing, harvesting and processing.
